Total Fluids Recovery - PumpsQED AP4+ Autopump®The Next Generation AutoPumpEasier to Disassemble and CleanThe AP4+ was made easier toclean by borrowing from ourHammerHead® pump design, using3 bolts to attach the pump inlet andopen up the pump. This is easierthan having to rotate the inletmultiple turns to unthread it fromthe center tube inside the pump,especially under field conditionsof silt, deposits and coatings.Removing the inlet is also aided bythe new, precision ID pump casing,ensuring a more controlled fit.The new pump casing’s smootherinternal surface has the addedbenefit of reducing the rate ofbuildup of solids and coatings insidein some cases. The Easy Fittingsmake it a snap to remove the tubingfrom the pump without cutting, andthe float is now easily removed bypulling a clip.Upgraded MaterialsThe new AP4+ features upgradedmaterials for many parts to furtherextend the service life of thepump and to broaden the rangeof conditions each model can beused in. All nonmetallic internalparts are now made of PVDF*; thisis a high-grade engineering plasticwith higher strength at elevatedtemperatures and extremely broadchemical resistance, includingto acidic and oxidizing cleaningagents sometimes used for pumpmaintenance. All stainless steelparts have been upgraded to304 grade or higher for improvedcorrosion resistance.Expanded 5-year WarrantyThe new and improved warranty,a straight 5-year warranty with nopro-rating, is proof of the AP4+’ssuccessful history and continuedimprovements.Of course, the new AP4+ iscompatible with the AutoPumpFamily ofAccessories, including:• Sheathed nylon pump tubing setsfor maximum chemical resistance,reduced weight, less tangling andeasier handling, another innovationlead by QED.• QED’s Easy Fittings for affordable,quick connection and removalof the pump from its tubing set,built to function easily even underhigh solids well conditions. Theseare now available pre-installed topump and tubing so pump systeminstallation just snaps together!• QED’s Easy Bolts for rapid access toflanged wellheads.• The industry’s widest range ofwellhead completions to matchyour site so that pump installationgoes smoothly.

Total Fluids Recovery - PumpsGROUNDWATERREMEDIATIONLeachate Knock-Out PotLandfill Gas (LFG) is saturated withwater vapor. As the gas cools in theextraction system piping, the vaporcondenses into droplets that becomeentrained in the gas flow. Eventually,the droplets combine and pool asLFG condensate. Accumulations ofcondensate in LFG pipelinescan obstruct and in some cases,completely block gas flow. This canlead to surging in the gas lines,making extraction system controland tuning difficult. Therefore, LFGcondensate must be removed in acontrolled manner. In cases whereenvironmental regulations prohibitthe return of condensate to thelandfill, the Knock-Out (KO) PumpSystem plays an integral role inachieving regulatory compliance.Key Benefits• Completely prefabricated andfactory tested• Easily installed and maintained• Safe and reliable pneumatic orelectric design• Quick-connect fittings• Durable Polyethylene or PVCconstruction• Corrosion resistant componentsAutomatic OperationReduces CostsGas velocity moves the stream ofentrained moisture through thepipeline and into the KO unit wherethe condensate is separated fromthe LFG stream using a cyclonicseparation process. Eliminationof direct impact reduces pressuredrop.While LFG exits the outlet pipe, thecondensate is temporarily held inthe intermediate transfer reservoir.A pneumatic AutoPump andlevel controller mounted directlyabove the reservoir, automaticallydischarges the condensate to anappropriate point of disposaleliminatingthe costs of dailychecking and manually pumpingindividual traps, low spots andother collection points.KOInlet/Outlet SizeFlow Rate(SCFM)PressureDrop(Inches H 20)200mm (8”) 1140 2.0250mm (10”) 1700 1.9300mm (12”) 2400 2.1350mm (14”) 2400 1.9TypePneumaticSubmersibleMax.FlowMax.DischargeHead30 lpm 61mKnock-Out in-line DesignSimplifies InstallationsThe KO system is designed tobe installed in-line with the LFGpipelines, with its inlet and outletattaching to a straight or slopingpipeline segment.

Total Fluids Recovery - PumpsQED Pulse PumpCleanup well conditions canbe extremely hostile: powerfulsolvents, gasoline and fuel oil,strong acids, caustic bases,corrosive chlorides. That’s why QEDmakes the Pulse Pump series (ourbasic gas displacement pumps) ina variety of proven materials thatwon’t just survive, but will deliveryears of trouble-free performance.Every Pulse Pump model has onlytwo moving parts downwell andhigh-clearance, self-cleaningball check valves. This simplicitykeeps them working when highsolids, viscosity, or chemical attackcause other pumps to clog orbreakdown. An external controller isrequired to control the alternatingpressurisation and venting cyclesfor the pump.The Pulse Pump design is especiallysuited for sinking hydrocarbons(DNAPL) recovery, which is oftencomplicated by high viscosity and/or extremely aggressive solvents.Intrinsically safe Pulse Pumpsystems are fast and easy to install,with no electrical connections atthe wellhead.Flow optimisation is simple too;rugged, dependable pumps andcontrollers (the solar/AC poweredC100M and the all-pneumatic L360)deliver reliable operation withoutneeding frequent attention orrepair.Suitable for harsh environments,including the most demandingground water cleanup, leachatecollection and sinking layerrecovery applications.How it worksThe Pulse Pump is air-poweredand requires an external timerbasedcontroller to control theair cycling OFF and ON to thepump. The external controllerprovides alternating cycles ofventing to allow the pump to fill,and pressurising to discharge theliquid from the pump. The pumpfills through the intake check valveduring the refill portion of the cycle,while the pump discharge checkvalve is sealed.

Total Fluids Recovery - PumpsGROUNDWATERREMEDIATIONQED Slider PumpDesigned forangled wells 20° to 90°The increased availability of specialdrilling equipment has caused morelandfills and cleanup projects toappreciate the unique advantagesof low-angle (slanted or horizontal)wells or risers where conventionalvertical wells are inefficient orimpossible to use.Sloped landfill risers for leachateand/or landfill gas allow wellheadinstallations and other equipment tobe placed outside landfill cells, notin the middle of them. This protectsheaders and other equipment andfacilitates normal landfill operations.Cleanup projects can also benefit.Narrow water or product layers canoften be more efficiently interceptedby a horizontal well. Inaccessiblecontaminant plumes under buildingsor sensitive areas can be reached;the technique is also a cost-cuttingalternative to trenches for capturingwidespread floating layers.QED Slider pumps provide theanswer. They have proprietaryangle-independent valves tooperate at any orientation andcan deliver reliable flow, at ratesup to 35.9 Lpm/51.7 m3/day in 5in.(125mm) and larger wells. They canalso be modified to fit 4in. (100mm)wells. They are especially suitedfor tough landfill duty, providingexcellent resistance to sedimentclogging and solvent attack.

GROUNDWATERREMEDIATIONHydrocarbon Recovery - Guide to Product RecoveryEquipment SelectionGuidelinesSelecting the best equipment forLNAPL and DNAPL source reductiondepends on matching it to the siteconditions and project goals.The major factors to consider are:What are the project goals andconstraints?• Importance of pumping LNAPLor DNAPL only, and not water• Expected duration of project• Total volume of LNAPL or DNAPLto be removed• Availability of site labor forservice• Overall budgetWhat is LNAPL?The USGS defines light non-aqueousphase liquids as liquids that aresparingly soluble in water and lessdense than water. For example, oilis an LNAPL because it “floats” ontop of water and does not mix withwater. Hydrocarbons, such as oil andgasoline, are examples of LNAPLs.At LNAPL contaminated sites LNAPLcan form a pool in the subsurface ontop of the water table.USGS Website:http://toxics.usgs.gov/definitions/lnapls.htmlAccessed 18/08/08What is DNAPL?According to the USGS, DNAPL(dense non-aqueous phase liquid)is a liquid that is denser than waterand does not dissolve or mix easilyin water (it is immiscible).In the presence of water it formsa separate phase from the water.Many chlorinated solvents, such astrichloroethylene, are DNAPLs.USGS Website:http://toxics.usgs.gov/definitions/dnapl_def.htmlAccessed 18/08/08Does everything fit into the well?Equipment selection depends onwell diameter, well depth, depth towater and its fluctuation and LNAPLor DNAPL layer thickness.What’s being removed?The type of fuel or solvent, itsviscosity, density, temperature,age of spill and the presence ofbiological growth or debris affectequipment performance.What LNAPL or DNAPL removalrate is needed?The hydraulic conductivity of theformation, the LNAPL or DNAPLrecovery rate in the wells and thepumping strategy determine themaximum LNAPL or DNAPL flowrate that will be required.12

At the same timethat these parameters affect themigration of the plume, they alsoplay a very important role in theselection of the right skimmer forthe cleanup application.SOS InletThe SOS inlet uses a float with aninlet port inside a hydrophobic,or water-rejecting screen. Thehydrophobic screen prevents waterfrom being taken in and pumpedto the surface, even if the floatoccasionally sticks or drags as theliquid level fluctuates. The SOS inletscreen is subject to plugging due topotential debris or slimes presentin the well, therefore the SOS inletworks best on fresh gasoline and jetfuel spills and less so on weathereddiesel.GROUNDWATERREMEDIATIONItem CodeCannisterVolumeOrdering InformationQED301079 SOS2 Passive Skimmer,600cc, 30cm travel for50mm wellsQED301080 SOS2 Passive Skimmer,900cc, 30cm travel for50mm wellsQED301032 SOS4 Passive Skimmer,3000cc, 46cm travel, for100mm wells and largerQED301033 SOS4 Passive Skimmer,6000cc, stainless steel,46cm travel, for 100mmand larger wellsWell DiameterTravelRangeOverallLengthQED301079 600 cc 50mm (2 in.) 30 cm 165 cmQED301080 900 cc 50mm (2 in.) 30 cm 196 cmQED301032 3,000 cc 100mm (4 in.) 46 cm 173 cmQED301033 6,000 cc 100mm (4 in.) 46 cm 216 cm15

The use of abladder pump eliminates air contactwith the LNAPL fluids, minimisingemulsification and eliminating VOCemissions.The AutoGenie uses an integralpneumatic timer to control thepump fill and discharge times. Acomplete line of matched accessoriesis available to help with installationand performance, including in-welltubing, well caps, ON/OFF timers,LNAPL collection tank full shutoffsand other items.How it worksThe LNAPL enters the skimmersystem through the floating inlet,flows down through a flexibletube, then is pulled upward by thepump’s suction action during thefill cycle.During the discharge cycle,the bladder is squeezed by thecompressed air and the LNAPL ispumped to the collection systemat the ground surface. Then, duringthe fill cycle, the compressed airaround the bladder is exhaustedagain and the bladder expands,resuming its original shape. Thispulls fluid into the bladder throughthe check valve at the bottom ofthepump.SPG InletThe SPG (specific gravity) inlet usesa float with a controlled specificgravity that causes it to float onwater but not in the LNAPL. TheSPG float has its fluid inlet portpositioned near the top so that itis always above water. If the LNAPLlayer gets too thin, the SPG inletwill also be above the LNAPL layerand cease recovery of hydrocarbonsuntil more enters the well.To accommodate a range of finalLNAPL layer thickness, the SPG floathas multiple, variable inlet portsthat can be opened or plugged toadjust the level of the inlet port.Why isn’t the SPG always setfor the thinnest possible LNAPLlayer?The reason is that any float in asmall diameter well has a tendencyto occasionally stick as liquid levelsmove up and down, so setting theinlet port too low increases thechance of allowing water to bepumped instead of pumping onlyLNAPL. So, a trade-off must bemade between achieving desiredfinal LNAPL layer thickness andprevention of pumping water.SOS InletThe SOS inlet uses a float with aninlet port inside a hydrophobic,or water-rejecting screen. Thehydrophobic screen prevents waterfrom being taken in and pumpedto the surface, even if the floatoccasionally sticks or drags as theliquid level fluctuates. While this is adistinct advantage of the SOS inletover the SPG type, the SOS inletscreen is more subject to pluggingdue to potential debris or slimespresent in the well. The SOS inletworks best on fresh gasoline and jetfuel spills and less so on weathereddiesel.GROUNDWATERREMEDIATIONChoose the mosteconomical system1-3 wells: AutoGenie4+ wells: Programable Genie& controllerProgrammable GenieSee page 200»»17

Hydrocarbon Recovery - LNAPL Recovery (Floating Product)QED AutoSkimmerFor High Recovery WellsThe AutoSkimmer Pump Systemautomatically recovers LNAPL layersand pumps on demand when thepump is filled.Advantages• High flow, automatic operation forrecovery wells with high LNAPLrecovery rates.• Versatile design allows floatinginlet removal for conversion tototal fluids pumping after theLNAPL later is largely eliminated.• Air-powered, intrinsically safe.• Built-in ON/OFF control withinternal float.• Proven reliability and durability.Combining the industry-leadingAutoPump with the rugged SPGfloating inlet, the AutoSkimmerdelivers higher LNAPL flows forwells with very high floating layerrecovery rates. The system can thenbe switched to even higher flow,total fluids pumping by removingthe floating inlet.When site conditions call for thisapproach, nothing beats theAutoPump/SPG inlet combination;both of these technologies havebeen proven in the field for manyyears around the world.The AutoPump mechanism meansthat the pump cycles only whenit is filled with LNAPL, reducingair consumption without addingany additional controls or sensors.The SPG inlet includes selectableside inlet ports for versatility infine-tuning LNAPL intake whenthe floating layer is reduced inthickness.How it worksSpecific gravity and viscosityare two of the most importantproperties of hydrocarbons(LNAPL) as far as their mobility inthe subsurface. At the same timethat these parameters affect themigration of the plume, they alsoplay a very important role in theselection of the right skimmer forthe cleanup application.SPG InletThe SPG (specific gravity) inlet usesa float with a controlled specificgravity that causes it to float onwater but not in the LNAPL. TheSPG float has its fluid inlet portpositioned near the top so that itis always above water. If the LNAPLlayer gets too thin, the SPG inlet willalso be above the LNAPL layer andcease recovery of hydrocarbonsuntil more enters the well.To accommodate a range of finalLNAPL layer thickness, the SPG floathas multiple, variable inlet portsthat can be opened or plugged toadjust the level of the inlet port.Why isn’t the SPG always set forthe thinnest possible LNAPL layer?The reason is that any float in asmall diameter well has a tendencyto occasionally stick as liquid levelsmove up and down, so setting theinlet port too low increases thechance of allowing water to bepumped instead of pumping onlyLNAPL.

GROUNDWATERREMEDIATIONFerret® In-Well SeparatorIn-Well SeparatorFerret® In-Well Separators providean alternative method for reliablyand safely removing floatinghydrocarbon (LNAPL) layers fromwater at remediation wells, sumpsand tanks. Instead of relying solelyon a selective inlet float to avoidpumping water, the Ferret® usesa unique internal separator valveto sense the difference in specificgravity between the hydrocarbonand water, then pumps purehydrocarbon and rejects any waterback into the well.Hydrocarbon Recovery - LNAPL Recovery (Floating Product)Advantages• Unique design uses specificgravity differences to separateLNAPL from water down well.• For sites with well conditionsthat hinder proper functioning ofhydrophobic screens.• Available in sizes to fit 2in. and4in. wells.• Simple, rugged. Air-poweredpump is durable and easy tomaintain.• Programmable, solar-poweredcontroller provides easy flexibilityof pumping rates and OFF timesto optimise LNAPL recovery rates.This in-well separation methodcan be advantageous for wellconditions that hinder theperformance of hydrophobicscreens. Fixed Inlet Ferrets havethe best resistance to fouling indifficult wells. All Ferrets use theextremely rugged and simple airdisplacement pumping principle topump the LNAPL to the surface andthe programmable, solar-poweredC100M Controller to select pumpingcycle times and system OFF periodsto match LNAPL recovery rates.Ferret models are available in sizesto fit 2in. and 4in. wells. Models areoffered with or without floatinginlets to match site needs and userpreferences; floating inlets canimprove overall LNAPL pumpingrates, but the restrictions inherentin floats and tubing coils can hinderLNAPL flow in wells that are highlyfouled or have high viscosity fluids.A complete line of matchedaccessories is available tohelp installation and systemperformance, including in-welltubing, well caps, LNAPL collectiontank full shutoffs and other items.NameHigh Capacitywith Fixed InletHigh Capacitywith Floating InletStandardwith Fixed InletStandardwith Floating InletModel No. HIWS42 HIWSFI12 AIWS22 AIWSFI12Overall Length 58 cm 128 cm 76 cm 119 cmOD 90 cm 90 cm 45 cm 45 cmFloating LayerDensityMax Viscosity0.90 cc 0.90 cc 0.90 cc 0.90 cc1,000 cSt350 cSt 100 cSt 4 cSt22Min Liquid Depth 46 cm 89 cm 54 cm 89 cmInlet type andRangeMax Flow Rate*Max LNAPL Volumeper Cycle**Compatible FloatingLayer LNAPLsStationary1137 Lpd with 91 cmLNAPL1,300 mL if no watertaken inFloating with 31 cmrange0140 Lpd with 30 cmLNAPL1,300 mL if no watertaken inStationary379 Lpd with 30 cmLNAPL280 mL if no water takeninGasoline, jet fuel, kerosene, fresh and weathered diesel, #2-#5 fuel oil, lightweightmotor oils, and hydraulic fluidsFloating with 31 cmrange379 Lpd with 30 cmLNAPL280 mL if no water takeninGasoline, jet fuel,kerosene, fresh dieselfuel, and #2 fuel oilMaterialsStainless steel, brass, Delrin®, Viton®; Floating inlet models include epoxy float and fuel grade tubing coil.FittingsBrass compression: discharge - 1/2 in.

Hydrocarbon Recovery - AccessoriesQED Tank Full ShutoffFor the ultimate in safety andreliability, QED offers premium, allpneumatictank full shutoff controlsin wall-mount (301425) and tankmount(301426) versions. Both ofthese field-proven controls use failsafeand redundant mechanismsto ensure that the pumping systemis reliably switched off when theLNAPL or DNAPL collection tank isfull.Method of OperationThe TFSO System will cease passingcompressed air to downstreamsystems when the recovery tank isfull.The hoses are colour coded and allthe fittings are different so only theproper connections can be made.The TFSO control includes a twostage filter/regulator. Another filteris provided into the control box foradded reliability; this filter also has avisual indicator.Features• Hoses and tubing are colourcoded and all the fittings aredifferent so only the properconnections can be made.• System operation is simple,straightforward and automatic.Built-in safety features result inoperator-free operations even onnights and weekends.• The TFSO system can beupgraded to monitor additionalrecovery tanks.• The TFSO system is small andlightweight and can easily bemoved from site-to-site.• The Wall-Mount TFSO has a threewayvalve that allows the operatorto shut down the system,exhausting all downstream airwithout disconnecting hoses or“tripping” the system.• Rugged construction ensureslong system life, even underharsh conditions.• The entire system ispneumatically powered withno electrical components, thusavoiding sparks in control powerand sensing devices.C100M Level SwitchOverfill Protection DeviceWhen high levels are detected,the C100M will discontinue pumpoperation and will enter andremain in a “Tank Full” and “SystemDisable” mode; to resume normaloperation, the tank level must belowered sufficiently to deactivatethe switch and the C100M must bemanually reset.Once installed, any disconnectionsor breaks in the switch cablewill also cause a “Tank Full” and“System Disable” response.GROUNDWATERREMEDIATIONOrdering InformationQED301425 Wall mount tank full shutoff control boxQED301426 Tank full shut off, tankmount control boxWall mount shutoffTank mount shutoffOrdering InformationQEDCTRLSW Downwell Pump LevelSwitch Kit, to be used in combinationwith the Model C100M Digital ControllerQEDCTRTFO Tank Full Shut-Off Kit, tobe used in combination with the ModelC100M Digital ControllerFor C100M ControllerSee page 205»»25

GROUNDWATERREMEDIATIONQED Pulse PumpCleanup well conditions canbe extremely hostile: powerfulsolvents, gasoline and fuel oil,strong acids, caustic bases,corrosive chlorides. That’s why QEDmakes the Pulse Pump series (ourbasic gas displacement pumps) ina variety of proven materials thatwon’t just survive, but will deliveryears of trouble-free performance.Every Pulse Pump model has onlytwo moving parts downwell andhigh-clearance, self-cleaningball check valves. This simplicitykeeps them working when highsolids, viscosity, or chemical attackcause other pumps to clog orbreakdown. An external controller isrequired to control the alternatingpressurisation and venting cyclesfor the pump.The Pulse Pump design is especiallysuited for sinking hydrocarbons(DNAPL) recovery, which is oftencomplicated by high viscosity and/or extremely aggressive solvents.Intrinsically safe Pulse Pumpsystems are fast and easy to install,with no electrical connections atthe wellhead.Flow optimisation is simple too;rugged, dependable pumps andcontrollers (the solar/AC poweredC100M and the all-pneumatic L360)deliver reliable operation withoutneeding frequent attention orrepair.Suitable for harsh environments,including the most demandingground water cleanup, leachatecollection and sinking layerrecovery applications.How it worksThe Pulse Pump is air-poweredand requires an external timerbasedcontroller to control theair cycling OFF and ON to thepump.

Hydrocarbon Recovery - DNAPL (Sinking Product)QED EliminatorThe Eliminator is a high capacitybladder pump designed for LNAPLand DNAPL removal in 2in. (50mm)and 4in. (100mm) wells. TheEliminator is also used to handleviscous contaminants, such as crudeoil.Advantages• 100% air-powered operation.• No contact between drive air andcontaminated fluids.• Effective skimming of viscoushydrocarbons, such as crude oil.• Available for 2in. (50mm) and 4in.(100mm) wells or larger.The Eliminator uses a bladder of PTFEor elastomer to isolate the pump airsupply from the pumped liquid. Asa result, there is no contact betweenthe drive air and the contaminatedfluids inside the bladder andtherefore, no emissions of potentiallycontaminated air.Eliminator pumps provide reliabletop-inlet skimming or bottominletpumping. A wide range ofaccessories is available, including“roving” well caps to allow accuratepump inlet positioning, and bladderreplacement kits for easy fieldmaintenance.The Eliminator is powered bycompressed air and requires anexternal timer based controller tocontrol the air cycling ON and OFFto the bladder pump.Compressed air is supplied directlyto the Eliminator via an externalcontroller.When the bladder is squeezed fromthe outside by the compressed air,fluid within the bladder is forcedout through a check valve at the topof the pump.Then, when the air pressurearound the bladder is exhausted,the bladder expands resuming itsoriginal shape. This pulls fluid intothe bladder through either the topor bottom inlet, depending on thepump inlet configuration.Model No. 301301 301311 LP1702Pump TypePneumaticbladderPneumaticbladderPneumaticbladderInlet Top or Bottom Top or Bottom Top or BottomOutside Diameter 4.3 cm 4.3 cm 7.5cmLength 145 cm 208 cm 102cmWeight 1.6 Kg 1.6 Kg 5.2 kgMaterialFittingsFitting SizesStainless Steel,brass,Viton®, Teflon®,urethanebladderBrass quickconnectsLiquid Discharge:1/4 in.

Miscellaneous RemediationAutoTracker®Vacuum Extraction InletHow to Supercharge YourDual-Phase Extraction ProjectThe patented AutoTracker FloatingExtraction Inlet optimises dual-phaseextraction and bio-slurping systemperformance by assuring proper airto-waterratios even as water levelschange.Groundwater fluctuations can causesevere disruptions for dual-phaseextraction systems using a fixedentrainment drop pipe.When the water table falls belowthe elevation of a fixed extractioninlet, groundwater recovery ceasesand treatment efficiency decreases.When the water level rises above theend of a fixed inlet, vapor recoverybecomes impossible. AutoTrackerFloating Extraction Inlets eliminatethese common causes of systemshutdowns and missed recoverygoals.The Problems with ConventionalFixed Drop Pipe Systems are:• Conventional fixed drop pipeDPE system depends on precisepositioning• Small changes in well liquid levelcan shut the operation down• AutoTracker eliminates theseproblemsHow it worksDual-phase extraction (DPE) is thesimultaneous recovery of gases andliquids from the same remediationwell without the use of pumps andcontrols at each well. High velocityvapor flow entrains the water andallows it to be extracted fromdepths beyond the static suctioncapability of the vacuum source.With the right site conditionsand with the gas and liquid inletsproperly positioned, this canbe a highly effective method ofcontaminant recovery from boththe saturated and vadose zones.However, installation of systemswith a fixed entrainment tubecan be complicated and timeconsuming,and changing liquidlevels in the remediation wellcan cause costly downtime andnecessitate frequent site visits formaintenance, increasing both O&Mand life cycle costs.AutoTracker Floating ExtractionInlets from QED will deliveroptimum performance from yourDPE system by continuously andautomatically reacting to changesin well level, positioning gas andliquid inlets properly and allowingthe system to function at peakefficiency at all times.Case studies with AutoTrackershow that you can:• Cut O&M costs by 20% instantly• Clean up your site 33% faster• Save 1/2 of the life cycle cost.GROUNDWATERREMEDIATION31

GROUNDWATERREMEDIATIONActivated CarbonFiltration DrumsActivated Carbon has a variety ofuses in remediating contaminatedair, liquid and water. Carbonfilters are used for air and liquidpurification covering the entirespectrum of applications and flowrates.Drums of carbon can be expectedto adsorb up to 10-15% of theircarbon mass with hydrocarboncontaminants and up to 30% forchlorinated compounds. This simplerule will allow you to estimate howlong a drum of carbon will last atyour site. Simply divide your ppmconcentration into the weight of thecarbon to get the volume the drumscan process. Maximum influentconcentrations for liquid streamsare 40 ppm.
