Intensification of low-turbidity colored water treatment in a sludge blanket clarifier (part 1)

Summary

The specific features of high colored low turbidity water treatment in clarifiers with sludge blanket during representative time periods with low temperatures and water alkalinity are considered by the example of the Vologda water treatment facilities. The results of investigating chemical pretreatment of water from the Vologa River and Koubenskoye Lake during flood periods with the use of various oxychloride and aluminium sulfate trademarks as well as cationic and anionic flocculants are presented. The advanced methods of enforcing water treatment process in a sludge blanket are covered. The results of studying a «clarifier-filter with floating media» combined system are presented.
