Produced Water TreatmentNutshell media filters are commonly used in the treatment of produced water to reduce the oil and solids contentof the water prior to injection for Enhanced Oil Recovery (EOR) or prior to subsequent treatment such assoftening the water as feed to steam generators, used in heavy oil production.The Spectrum Plus Micro Media Filter is a nutshell filter with a difference. It has the unique ability to remove oiland suspended solids to much lower levels than can be achieved by conventional nutshell filters.ProblemResidual oil and suspended solids which are present in nutshell filtrate result in downstream operationalproblems.SolutionImproved filtration provided by Spectrum Plus Micro Media Filter results in significant improvement todownstream processes.Typical Produced WaterTreatment ProcessesPolishingFiltrationInjection well for disposal orwater floodingUpgrade FilterPerformance withSpectrum PLUSMicro Media Filteroffshore oceandischargeSoftenerSoftenerPolymerReverseOsmosisInjection well forpolymer floodingSurface dischargefor irrigationCPISkimTankIGFNutshellFilterSoftenerSteam generationfor steam injectionTypical Filtrate QualityOil: 2 - 5 ppmSuspendedSolids: 2 - 5 ppmLimeSoftenerFilterSoftenerSteam generationfor steam injectionSpectrumMicro MediaFilterTypical Filtrate QualitySuspendedSolids: 2 - 5 ppmTypical Filtrate QualityOil: 2 micronSoftenerEvaporatorSteam generationfor steam injection

Spectrum Plus Micro Media FilterSuperior DesignSpectrum’s lower layer of micromedia features a very small particlesize and acts as a barrier to smallsuspended solids. The Spectrummicro media is a proprietary, inert,long-life (virtually permanent) media.It is much heavier in density thannutshells or sand which ensures thatit reclassifies (resettles below thenutshells after backwashing) and isvirtually impossible to backwash outof the filter vessel.Nutshell MediaParticle Size: 20 - 30 meshConventionalNutshell FilterSpectrum PlusMicro Media FilterNutshell MediaParticle Size: 20 - 30 meshDesigned for simple, low cost operation• Nutshell media is effectively scoured using air or gas - no separate pumps or agitators are required• 15 standard models ranging from 1,500 - 60,000 BPD (50 - 2,000 gpm, 11 - 450 m 3 /hr)Spectrum Micro MediaParticle Size: 80 - 230 meshSuperior PerformanceAccording to field testing on produced water going into and out of filters during nomal heavy oil production operations- Traditional Sand/Nutshell Filters vs. Spectrum PLUS Micro Media FiltersSpectrum Plus Micro Media Filtervs. Conventional Filter PerformanceSpectrum Plus Micro Media FilterSolid Particle Removal by SizeConventional (Nutshell or Sand Filters)Spectrum Plus Micro Media FilterSpectrum removes 99.8% of particlescompared to 75% by traditional filters.Measured by a Standard Method test1.2 micron Millipore paperSpectrum Micro Media Filtereffectively removes virtually allparticles down to 1 micronAccording to Particle Size Analyzer

Benefits of Superior Filtration by Spectrum Plus Micro Media FilterDownstream Process Problems With Conventional Nutshell Benefits With Spectrum PlusInjection WellCartridge Filters Before InjectionWellIon Exchange SoftenerLime Softener• Suspended solids result in rapid clogging ofwell or reservoir• Suspended solids result in high material andlabor costs in cartridge filter replacement• Suspended solids result in flow restrictionsand/or channeling in resin beds• Oil results in fouling of resin• Results of above are either higher hardness intreated water which causes other downstreamproblemsor• Higher operating costs in terms of regenerantchemicals and resin replacement in order tomaintain softened water quality• Oil interferes with chemical performance oflime softener• Longer injection well operating life and improved flowthrough oil field• Cartridge filters can be eliminated saving capital cost andsignificant labor and material costs• Spectrum Filter filtrate is comparable to a 1 microncartridge filter - far better than the 5-10 micron ratedfilters often used in such service• Elimination of fouling of downstream ion exchange bysuspended solids - the very small solids that pass througha Spectrum Filter will pass through a conventional ionexchange softener• Reduction of oil fouling of ion exchange resins• Results of above are more consistent ion exchangerperformance and consistently softer treated water• Cleaner resins require less regeneration and cleaningchemicals and labor to maintain them• Cleaner resins last longer - reducing downtime and costfor resin replacement• Reduced oil entering lime softener improves limesoftening process because particles do not becomecoatedwith oil• Less chemicals may be used• Fewer process upsetsEvaporator • Oil interferes with operation of evaporator • Reduced oil entering evaporator improves crystallizationand overall process and reduces scaling potentialA 30,000 BPD Spectrum Plus Micro Media Filterfeeding an Eco-Tec RecoPur ® SAC brineregenerated softener supplying a steam generator.Contact Eco-Tec for more information aboutRecoPur ® water softeners!eco-tec.comFor more information, or to request a quick proposal, visit our website or contact:Eco-Tec Inc.1145 Squires Beach RoadPickering, OntarioCanada L1W 3T9Phone: (1) 905-427-0077Fax: (1) 905-427-4477ecotec@eco-tec.comEco-Tec Western Canadian OfficeSuite 325, 400 5th Avenue SWCalgary, AlbertaCanada T2P 0L6Phone: (1) 403-303-2855Fax: (1) 403-264-9218ecotec@eco-tec.comEco-Tec Solutions - IndiaNo 5 City Center,930 Synagogue Street, Camp,PUNE, India 411 001Phone: (91) (020) 64001056Fax: (91) (020) 26052160eco-tec@eco-tecsolutions.comProsep Technologies LimitedUnit 6A, Zone 4, Burntwood Business ParkBurntwood, StaffordshireEngland WS7 3XDPhone: +44(0)1543 675731Fax: +44(0)1543 679484ptl@eco-tec.comAll statements, information and recommendations contained herein are, to our knowledge, true and accurate.
