… treatment consists of a chemical treatment step with chemical precipitation, flocculation, sedimentation and filtration, and a final step with a carbon and peat filter. Renova has to ensure that the condition of the leachate reaches the regulation set for the landfill before it …
… been compared with current guidelines for vehicle washes. A new washing and flocculation method have been developed during the study. The proposed new method is suitable as pretreatment of the water before discharging it, as it reduces metal emissions and provides better washing …

… is 567 mg/l. Before the anaerobic step the water is pre-treated by adding of flocculation chemicals and sedimentation. The total amount of suspended material is reduced by 50 % in the pre-treatment and the load on the UASB-reactors is 100 mg/l. With a hydrologic retention time …
… lignin degradation) do not degrade remarkable during wastewater treatment. Flocculation of COD is one way to reduce the discharge to the recipient. Addition of 2,6 g/l PAX-18 (a high charged aluminum complex) to the wastewater from the bleaching plant gives a reduction of 40 % …
… system. The water purification starts with a mechanical grid followed by flocculation and then through a sand filter before pH adjustment and chlorine. To adjust water levels in the pools drinking water is added when needed. Chlorine is a common and effective disinfectant but …
