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.展开更多

The main purpose of this research was to manage water quality at the Rosetta branch by improving effluent water quality at the Abu-Rawash WWTP. This research involved attempting to determine the optimal dose of aluminum chloride (AlCl3) to reach an acceptable treatment at the Abu-Rawash WWTP. A dose of 2.0 mg of AlCl3 for each liter of wastewater was selected. Another approach involves discharging flow from Al-Buhairi Water Canal to the El-Rahawy drain in order to increase the dissolved oxygen (DO) concentration and reduce pollutant concentrations at the El-Rahawy drain. Applying these approaches will significantly improve water quality at the El-Rahawy drain. The river pollutant (RP) modeling was also used to study the effect of improving water quality at the El-Rahawy drain on the Rosetta branch water quality. The RP modeling showed that applying the proposed solutions will significantly improve water quality at the Rosetta branch.展开更多

The main purpose of this research consisted of investigating alternatives of managing water quality at the Damietta branch;a comparison was conducted between the current situation and two proposed scenarios. The first scenario involved changing the effluent path of the Omar-Bek drain to another drain is called “Main Western drain”. The second scenario centered around improving water quality at the Omar-Bek drain by constructing a WWTP with a design capacity of more than 150,000 m<sup>3</sup>/day (39,625,800 gallons) and by improving water quality at this drain by increasing the efficiency of WWTPs that discharged daily about 60,000 m<sup>3</sup> (15,850,300 gallons) of partially treated wastewater to the drain. The current situation and the two proposed scenarios were simulated by using river pollutant (RP) modeling. It was concluded that the Omar-Bek drain has no significant effect on the Damietta branch water quality and that, instead of changing the path of the drain, improving the efficiency of the existing WWTPs discharging to the Omar-Bek drain and preventing the direct discharge of domestic wastewater to the drain will provide the most effective ways of increasing the water quality of the Damietta branch.展开更多

Water quality at the El-Rahawy drain is expected to improve after discharging water from the Al-Buhairi Water Canal to the El-Rahawy drain and improving effluent water quality at the Abu-Rawash WWTP.
