Liqui-Floc Chitosan 1%, 1.5%, 2% and 3% Acetate Is an organic water clarifier used in the removal of sediment and turbidity in storm water run-off. Chitosan-Enhanced Sand Filtration technology typically utilizes a chitosan acetate solution metered into a pipe to flocculate suspended solids prior to filtration. It is also used in gravitational settling, bio-filtration and conventional filtration systems. This natural biopolymer is 100 percent biodegradable through simple natural enzymatic activity, leaving you no bioaccumulation concern. Currently being used in construction, industrial, municipal, and log yard water treatment systems.
