Evaluation of natural flocculant efficiency in the harvest ...

13/05/2021· The significant contribution of this paper is to test different coagulants in different conditions of concentration in the coagulation and flocculation processes followed by sedimentation to evidence the best coagulant and the best condition for harvesting of Monoraphidium contortum biomass. So the proposed methodology aimed to perform preliminary tests using a tannin-based cationic coagulant ...

Coagulants and Flocculants | Walter Louis Fluid …

The most common use of cationic polymers in water treatment is for the coagulation and flocculation of sewage treatment sludge in the dewatering step. No separate coagulant is needed in many cases which actually means the polymer is both a coagulant and a flocculant. Anionic polymers are used commonly to treat water which has gone through a coagulation step with alum. Very small amounts, in ...
