Abstract
A chitosan enhanced dewatering bag reduces the amount of silt, sedimentation and suspended solids from incoming water. The dewatering bag includes a first permeable membrane having a first open end or opening, and one or more applications of chitosan located within the bag. A second permeable member may be attached to the first permeable membrane so that it defines at least a portion of the outer surface of the dewatering bag. A baffle wall may also be located inside the dewatering bag to reduce the access of silt and sediment to this second permeable membrane. Fluid entering the first opening can readily flow through the dewatering bag, while unwanted dirt and other solids are impeded from such flow.
