Chitosan based high performance filter with self-regenerating ability |
| abstract |
A self-regenerating chitosan based filter medium for disinfecting and purifying organic pollutants and other pollutants in a gas or liquid is disclosed herein. Porosity and surface charge of said filter medium is manipulative/tunable by varying one or more of the following parameter(s): concentration of chitosan, crosslinking density, amount of copolymers and additives, freezing temperature, freezing profile, and/or types of crosslinker used. The present filter medium is capable of self-regenerating under exposure to ultra-violet light for sufficient time and removing over 90% of the pollutants from each influent flowing through the filter medium. |
