DESI ChitoVan - Chitosan Acetate
Developed for Active Treatment. ChitoVan Chitosan Acetate is a high quality industrial grade chitosan solution containing the acetate counter-ion and is available in 1% (CA100) and 1.5% (CA150). ChitoVan CA is a clear viscous solution that is very stable (18-month or greater shelf life) in comparison to other flocculents that may degrade rapidly. Chitosan-Enhanced Sand Filtration technology typically utilizes a chitosan acetate solution metered into a pipe to flocculate suspended solids prior to filtration. ChitoVan CA is a powerful flocculent, and when used in CESF systems, is capable of consistently reducing turbidities by more than 95% to less than 10 NTU in almost every case. CESF construction site stormwater treatment with ChitoVan CA100 has been thoroughly tested through the Washington Department of Ecology Technical Review Committee and had been awarded a General Level Use Designation for batch, infiltration and flow-though to all receiving waters of the state.
ChitoVan CA is commonly used to treat stormwater run-off, dewatering water, ground water, waste water, process water, etc. Industries served include: construction, gravel washing, sand and gravel, food waste, mining, environmental remediation, log yard, boat yard, etc.
ChitoVan CA is offered in several volumes including: 5-gallon buckets, 55-gallon drums and 275-gallon totes. In most cases, turbid water (200 - 1000 NTU) requires approximately 10 gallons of ChitoVan 1% to treat 100,000 gallons (1 mg/L).
ChitoVan chitosan acetate is a powerful, safe and natural water treatment biopolymer that removes suspended sediment and other contaminants from water. ChitoVan is a powerful flocculent and when used with sand filtration, is capable of consistently reducing turbidities by more than 95% to less than 10 NTU. ChitoVan has been used across the U.S. and Canada to clean billions of gallons of water since its introduction in 2006.

Chitosan (shown above) is a natural biopo-lymer derived from chitin - the structural material found in crustaceans. Chitosan is a long chain polymer and possesses a strong positive charge. Dirt particles typically are negatively charged. Chitosan flocculates (clump together into a large mass) these fine particles causing the sediment to settle thereby clarifying the dirty water. (See before and after treatment below.)
ChitoVan is a versatile polymer with a wide range of water treatment applications throughout the construction and industrial field.
