The raw water pretreatment plant is designed principally for solids removal from the incoming Hanover county sewage effluent (grey water), backwash water and wastewater from the oily water collection system. Raw water enters a coagulation/flocculation chamber followed by a clarifier and dual media depth filters. Backwash water from the filters is periodically returned to the clarifier. Clarifier sludge is dosed with polymer before being thickened and then sent to the filter press for dewatering. The cake is sent to landfill and the recovered water returned to the clarifier.
What is the water used in CMF-S?
Raw (surface) water is pre-screened, and dosed with lime and carbon dioxide in a contact reactor to control alkalinity and corrosion. Next, water is dosed with a coagulant, liquid aluminium chlorohydrate (ACH) prior to entering the CMF-S plant to remove colour, some organic content, and dissolved metals.

Why is surface water more contaminated than ground water?
Typically, surface water requires more treatment and filtration than ground water because lakes, rivers, and streams contain more sediment and pollutants and are more likely to be contaminated than ground water. Some water supplies may also contain disinfections by-products, inorganic chemicals, organic chemicals, and radionuclides.

How are coagulants introduced into water?
These coagulants are introduced in the water when it enters the treatment plant. The water is then passed through flocculation basins where slow mixing takes place. This mixing makes sure that thorough coagulation takes place. Once coagulation is completed, the water is pumped into a sedimentation basin. Water is allowed to sit thus enabling the ...
