Screening of fungal coagulants and their application to reduce turbidity of river water

Surface and ground water contain both dissolved and suspended particles. Coagulation and flocculation processes are used to separate the suspended solids portion from the water. Conventionally suspended solids and turbidity are removed from raw water by various chemical coagulants but most of them a...
