Dewatering Filter Bags

Sediment filtering dewatering bag

Volm Dewatering Filter Bags are effective in collecting sediment from dewatering operations. Sediment-laden water is pumped into the bag. Volm Dewatering Filter Bags should be placed on a level area. (Bags can roll down slopes.) Insert pumps discharge hose into bag and secure the connection with clamp or tie wire. Volm filter bags can handle most applications utilizing 1″ – 6″ discharge hose.

Made from 8 oz. nonwoven needle punched geotextile with a AOS of 70 US sieve and 100 gpm/ft2 water flow, Volm’s Dewatering Filter Bags are strong and permeable. High pumping rates and high sediment loads can cause the bag to burst.

Applying our years of experience with woven poly meshes to the challenges facing the other industries just makes sense. The same top-quality mesh and poly (polyethylene) fabrics and specialty products can be used for erosion control (e.g. erosion control blankets, silt fencing, sand bags, etc.) and construction sites (e.g., privacy, theft management, and safety). Many applications are also helpful for agricultural and horticultural purposes. Examples of fencing materials include privacy fences, ski/snow fences and garden fences.
