Fungal flocculants to reduce turbidity of river water

River water contains both dissolved and suspended particles. Coagulation and flocculation processes are used to separate the suspended solids from the water. Conventionally, suspended solids and turbidity are removed from raw water by various chemical coagulants but most of them are costly and non-e...
