This pilot allows the knowledge of the basic processes of the Physico-Chemical Engineering of water treatment. These coagulation and flocculation processes facilitate the removal of MES and colloidal compounds. Coagulation consists of removing the electric charges present on the colloids to form larger particles that can more easily sediment by flocculation. The removal is carried out in the subsequent solid-liquid separation step: decantation. Under the action of gravity, the solid particles heavier than the liquid sediment. This method makes it possible to clarify important flow rates of solution.
This installation offers the possibility of varying the volume flow of the sludge:
(water flow) x (% sludge decanted in a given time)
horizontal surface of the clarifier
and to implement the levels of reagents obtained experimentally through the jar-test.
