Chitosan Passive Treatment Sock (PTS) is designed to treat construction and industrial storm water run-off by using an environmentally friendly biopolymer that does not contain any acrylamides. The fabric “sock” containing a dry form of chitosan, made from crab shell and is 100% biodegradable leaving no bioaccumulation concerns behind. PTS is a controlled dosing system for the passive treatment of suspended sediment in storm water, requiring no chemical injection pumps, or liquid chemical handling. Turbid water passes over the PTS unit and the chitosan product dissolves and releases through the fabric continually treating the water. When the water stops, the PTS unit dehydrates and remains static until storm water flows again.
