Dewatering Bag
Dewatering or Filter bags are used to collect silt, sediment and debris from dewatering operations
cfm dewatering bags are manufactured from 16 oz. non-woven needle-punched geotextile filter fabric with double-stitched seams. (AOS of 100 U.S. sieve and 50 gpm/ ft2). Bags can also be made using 8 oz. and 12 oz. non-woven fabrics.
To maximize performance of the bag, it should be placed on a level area. Insert the hose and clamp the fabric to the hose using wire, ties or clamps to create a seal.
Standard sizes:
10’x15’ for 2” discharge hose
20’x15’ for 3” discharge hose
25’x15’ for 4” discharge hose
