Abstract:
The effluent of nitro-phosphate plant contains very high amounts of total dissolved solids (TDS), total suspended solids (TSS), chemical oxygen demand (COD) and biochemical oxygen demand (BOD). These amounts are not in accordance to the standard of Government of Pakistan as mentioned in NEQs (National Environmental Quality Standards). The purpose of this project report is to design an industrial waste water treatment process for the effluent from Fatima Fertilizers Industries. The process includes equalization and neutralization (for flow and pH control), coagulation and sedimentation (for TSS removal), membrane bioreactor (for COD and BOD removal), ultrafiltration (for sludge and TSS removal) and reverse osmosis membrane system (for TDS removal). After the processing of the effluent TDS, TSS, COD and BOD are brought down to required NEQ standards
