Compact flocculation system with sludge and separators and thickeners at the Langenau Waterworks. Development and construction of a high-capacity flocculation system
A high-capacity flocculation method for processing river water into high grade drinking water is presented. Each step of the flocculation process is related to an exactly measured reaction space fitted with an agitator with adjustable speed. The sludge blanket is separated by lamellar separators. The two-way compact flocculation system ensures optimum purification even of extremely impure untreated water, with a flow-through time of 20 min. The amount of solids in the effluent is 0,5 ppm. The possibility of operating the former flocculation systems as bioreactors allows two stage biological NH4 elimination, and thus chlorine-free treatment even during cold months.
