Abstract
Talkha generation power plant is the only power plant located in El-Mansoura. It generates electricity using two different methods by steam turbine 2×210MW/h using mainly natural gas as fuel or mazout in case of deficiency of natural gas, gas turbine 8×25 MW/h, and combined cycle of steam and gas turbine 2×50 MW/h using natural gas or light fuel oil (Solar). Both plants draw its water from the River Nile 208m3/h. The plant has different units for treatment for producing drinking water 100m3/h, for water deminralization 108m3/h, for treating domestic waste 900m3/d, and for treating the industrial waste (400m3/d). The study aimed at studying the efficiency of the different treatment plants with suggesting suitable measures to improve the efficiency of the treatment plants. From all the treatment plants, except the water demineralization plant, a monthly sample was taken over one year from the different stages of treatment. With the water demineralization treatment plant, a monthly sample was collected along the first half year of the study from the different stages of treatment. Drawn water from the Nile is purified for drinking purpose. The units of water purification include coagulation, filtration, and disinfection. The raw water showed slightly alkaline medium (7.4-8) which was attributed to that natural water usually contain carbonates and bicarbonates of the alkali and alkaline earth metals. The annual mean values of standard plate count (SPC), total coliforms, fecal coliforms, and the total algal count of the raw Nile water samples were 313.3C.F.U./1ml, 2717/100ml, 1.3/100ml, and 3×104 org./l. The average removal efficiency of clarification for turbidity 55.5 after treatment by coagulation with alum was in compliance with EPA study (40-96). The annual removal efficiencies of the coagulation/sedimentations treatment process for SPC,
