Within Pennosan® there is over 25 years of experience in natural solid/liquid separation aids and clarification in wastewater treatment. Chitosan, the main active ingredient in Pennosan’s Floχan® range of water clarification and solid/liquid separation aids, comprises blends of the natural product chitosan, which is produced from fibres extracted from crustacean shells (typically crabs, shrimp, scampi and lobster). As such, the Floχan range is effective in a broad range of applications as well as being wholly biodegradable, safe to handle and easy to use.

Floχan formulations are prepared from chitosans with a range of molecular weights and high levels of deacetylation. In the Floχan range there are chitosan formulations suitable for all applications. In some applications, Floχan formulations can outperform many inorganic and synthetic polymer coagulating agents in removing partially soluble pollutants from solution. For other applications there are Floχan formulations that are as effective as non-biodegradable, petrochemical-derived flocculants at flocculating colloidal material and dewatering concentrated bio-solids sludges.

The big advantage of using Floχan chitosan formulations for industrial and environmental water treatment applications, particularly in those applications where there could be a direct impact on the natural environment, is that Floχan products are 100% biodegradable, safe and clean.
