| dc.description.abstract | The present study was conducted to evaluate the efficiency and performance of the wastewater Sewage
treatment plant at Gazipur City Corporation. The performance of this plant is an essential parameter to
monitor because the treated effluent is discharged for irrigation purposes. Wastewater samples were
collected from different unit operations of the plant. The main untreated outlet, primary treated outlet and
the final outlet. These samples were analyzed for various physio-chemical characteristics such as pH, TDS,
TSS, TS, hardness, alkalinity, DO, BOD. The results obtained have concluded that the waste water treatment
plant is efficient in the treatment of waste water. After the final treatment, it is found that the treated water
is satisfactory for irrigation. Dissolved oxygen was increased from zero (waste water) to 7.8 mg /liter after
secondary treatment. Total alkalinity and biochemical oxygen demand to tend to decreased with secondary
treatment. Total suspended solids and hardness decreased in treated water | en_US |
