Literature Research• Process selection• Bench testing for desalination of produced wateridentified an optimum process train includingoil/water separation, DAF, microfiltration, carbonadsorption, and RO• Biotreatment bench tests reached endpointconcentration for COD due to “recalcitrant organiccompounds” but is considered “cheap, effective andenvironmentally friendly” for COD reduction
Literature Research• COD in treated effluent• Multiple studies showed COD concentrations in therange of 200 to 300 mg/L• Extensive analytical program to identifycomponents of recalcitrant COD resulted inapproximately half “unknown”• One study reported 230 mg/L COD in treatedeffluent as “non-toxic to Artemia salina, which arevery frail organisms used to assess ecotoxicity”
