Abstract:

Tests were conducted to determine the feasibility for using nitrification and denitrification to control electrical conductivity in an industrial wastewater treatment process effluent. A laboratory-scale sequencing-batch reactor (SBR) system provided 98.5% COD removal and 99.5% nitrification when operating at a solids retention time of 12 days. The resulting average effluent COD concentration was 20 mg/L. Complete nitrification occurred within six hours of aeration but twelve hours of reaction time was required for denitrification. The nitrate-N concentration in the decanted SBR effluent averaged 21 mg/L. Completion of denitrification in downstream denitrification filters will reduce the EC from 1,210 to 852 μS/cm, thereby allowing the plant to meet its EC discharge standard.
