摘要：The Tala drain is the second major source of pollution along the Rosetta branch. The Tala drain receives discharge from dairy industry and agricultural drainage, as well as untreated domestic wastewater. This research involved attempting to improve water quality at the Rosetta branch by improving water quality at the Tala drain. Water quality at the Tala drain will be improved through improving effluent water quality from the dairy industry using aluminum chloride (AlCl3) as a coagulant, with injections of carbon dioxide (CO2), and constructing a new WWTP. Results indicated that the optimum aluminum chloride dosage was 225 mg/L at a pH value of 6.15. The estimated treatment cost of 1.0 m3 of dairy wastewater is $0.0425 per day. The river pollutant (RP) modeling was also used to study the effect of improving water quality at the Tala drain in the Rosetta branch water quality. The RP modeling showed that applying the proposed solutions will significantly improve water quality at the Tala drain and at the Rosetta branch.
