Aqua-Lator High Speen Surface Aerators

Water TechnologiesAqua-Lator®High Speed SurfaceAerators

OverviewTHE PRODUCTThe Aqua-Lator® aerator is a high speed floatingmechanical aerator for wastewater treatment. Powerfulpumping action transfers oxygen by breaking up thewastewater into a spray of particles, creating more surfacearea for atmospheric pressure to drive oxygen into thewastewater. At the same time, the oxygen enriched water isdispersed and mixed. The result: Effective wastewatertreatment.The Aqua-Lator® aerator represents years of accumulatedresearch and field testing in a broad range of municipal andindustrial applications throughout the world. No otherfloating mechanical aerator is as ruggedly built, more efficient,or as versatile. It provides excellent oxygen transfer,low operating costs, trouble-free performance andunequaled resistance to the environmental extremes towhich aerators are continually exposed.THE FIRSTThe Aqua-Lator® aerator was the first high speed floatingaerator. Introduced in 1963, it created imitators, but nonewho could ever duplicate its superior performance andreliability.EXCELLENT VALUEFrom the beginning, Aqua-Lator® aerators have deliveredexcellent value for thousands of municipal and industrialwastewater operators. Driving this track record has been aconsistent product philosophy of providing reliableperformance, simplicity of operation and ease ofmaintenance.SATISFIED CUSTOMERSSatisfied customers span the complete range ofwastewater treatment operations, from large citymunicipal treatment plants to the smallest village plant;from pulp and paper mills, food and beverage processorsand petrochemical plants to textile manufacturers.Industrial customers range from the top 500 corporationsto small companies.2

RESOURCES AND CAPABILITIESWe are located in a 40,000 square foot facility on 13acres in Roscoe, Illinois. Test facilities include a100,000 gallon circular tank and a 500,000 gallonsquare basin. These tanks are used for all vibrationtesting, performance evaluation and research anddevelopment programs. Our engineers can assist inthe selection of the optimal aerator size, placementand mooring.With the full resources of Siemens WaterTechnologies to support it, we offer the widest rangeof horsepower, materials of construction, motoroptions and electrical and mooring accessories.EXCEPTIONAL VERSATILITYThe Aqua-Lator® aerator offers exceptionalversatility. Units may be easily added,repositioned or upgraded to cope withchanging conditions. As additional aerationcapacity is required, new equipment canoften be placed in operation the same dayit is delivered. Because the Aqua-Lator®aerator is self-adjusting to varying waterlevels, it ensures continuous, optimumoperating efficiency for the many industrialusers who operate waste treatmentfacilities by the batch method or othersystems where the fluid level fluctuates.BROAD RANGE OF APPLICATIONSAqua-Lator® aerators are used in a widevariety of installations – aerated lagoons,sequencing batch reactors (SBR),stabilization basins, activated sludge andaerobic digestion systems, as well as forstream aeration, reservoir stagnationprevention and upgrading existing ponds.3

MooringAccessoriesMOORING CABLEMooring cables are designated by thenumber of strands in the cable andthe number of wires in each strand. Inthe cable that we specify, 7x19 means7 strands of 19 wires each. Allmooring cable is manufactured of7x19 strand, 304 stainless steel.HP DIA WGHT STGH2-30 3/16 65 3,70040-75 1/4 110 6,400100 3/8 243 12,000HP – Aerator horsepowerDIA – Cable diameter in inchesWGHT – Approximate weight per 100feet in pounds.STGH – Nominal breaking strength inpounds.SHACKLEHeavy-duty shackles, manufacturedof 304 stainless steel, are availablein 3/16”, 1/4”, and 3/8” for use withthe corresponding diameter mooringcable. The shackle is attached to thethimble. This allows for easydetachment of the aerator fromthe mooring line.EXTENSION SPRINGIn applications where there are smallamounts of variation in the waterlevel, stainless steel extension springsare used. The springs are installed atthe mooring points to allowapproximately 10 inches of expansionfor each springTHIMBLEHeavy-duty thimbles, manufacturedof 316 stainless steel, are available in3/16”, 1/4”, and 3/8” for use with thecorresponding diameter mooringcable.SNAP HOOKHeavy-duty snap hooks, manufacturedof 304 stainless steel, are available in3/16”, 1/4”, and 3/8” for use with thecorresponding diameter mooringcable. The snap hook is attached tothe thimble. This allows for simpledetachment of the aerator from themooring line for scheduledmaintenance or other services.3/16” - 1/4” MOORING HARDWAREARRANGEMENTFor up to 30 HP, mooring consists of 1thimble and 1 clip on each end of themooring line. Above 30 HP, use 1thimble and 2 clips on each end.WIRE ROPE CLIPHeavy-duty U-bolt clips, manufacturedof 316 stainless steel, are available in3/16”, 1/4”, and 3/8” for use with thecorresponding diameter mooringcable.12MOORING RINGMooring rings, manufactured of 304stainless steel, are used to connectaerators together when the aeratorsare not moored to shore, posts, orconcrete blocks.3/8” AND LARGER MOORINGHARDWARE ARRANGEMENTMooring consists of 1 thimble and 2wire rope clips on each end of themooring line. Install the U-bolt sectionof the wire rope clips on the “dead” orshort end of the cable, and the saddleon the “live” or long end of the cable.Apply the second clip as near thethimble as possible.

Typical MooringArrangementsAeratorAccessoriesSHORE MOORINGMost common mooring arrangement.Shore end connection is made toeyebolt or embedded anchor.LOW TRAJECTORY DIFFUSERThis fiberglass ring is bolted to thetop of the discharge cone to lowerthe aerator spray pattern. In colderclimates, this will help reduce thewindblown spray and minimize icing.ANTI-ICE DIFFUSERThis cast aluminum ring is bolted tothe top of the discharge cone tominimize ice build-up. The ringcontains heating cable and rangesfrom 1000 to 5000 watts, based onthe horsepower of the aerator. Theanti-ice diffuser is equipped with anintegral junction box which containsthe automatic thermostat. The anti-icediffuser requires its own 2-conductorelectrical power cable for operation.RESTRAINED MOORINGFor applications with large variationsin water level. A triangular frame withthree rings is attached to the float.These rings, which are removableU-bolts, fit around three posts,permitting the unit to slide up anddown the posts with varying waterlevels.ANTI-EROSION ASSEMBLYThe anti-erosion assembly consists ofa standard intake cone with anintegral plate, sized for that particularhorsepower. These antierosionassemblies are available in stainlesssteel or epoxy coated steel. Thisassembly causes water to be drawnfrom the sides, rather than fromdirectly below the aerator, thushelping to prevent bottom erosionthat can sometimes occur in earthenbasins. These assemblies are also usedto prevent disturbance of the sludgeblanket in facultative lagoon systems.DRAFT TUBEThe draft tube is simply an extensionof the intake cone to allow for adeeper intake of water in specificcustomer applications to promotecomplete oxygen dispersion andsolids suspension. Draft tubes areavailable in stainless steel or epoxycoatedsteel. Deep basins, in whichthe depth is more than 1.5 times thelength of the shortest wall, mayrequire anti-vortex precautions whendraft tubes are used.13

ElectricalAccessoriesCONTROL PANELControl panels, with NEMA®compliant enclosures, are available formanual, semi-automatic, orcompletely automatic operation. Astandard control panel consists ofacross-the-line starters, pushbuttonstart-stop switches, and a maindisconnect safety lever switch. Otherspecial enclosures which require suchitems as timers, pilot lights, alarmhorns, or elapsed time meters, areavailable upon request.MOTOR OPTIONSIn addition to all the standard featureson the Aqua-Lator® aerator motors,the following additional features areavailable:• Dual-speed• ES “Energy Saver”• Space heaters• Thermal overload protection• Explosion-proof• Special OSHA colorsSpecial NotesSPECIFICATIONS AND DIMENSIONSThe specifications and dimensions in thiscatalog are intended to be representativeand illustrative, of the size, function andappearance of our products.
