Effective solution for the collection of potential harmful sediments from dirty water pumped out of excavation works including flood water that would otherwise pollute the surrounding environment Sediment-laden water is simply pumped into the filter bag which trap the solids inside Allows filtered water to flow freely out through the geotextile fabric to disperse into the surrounding ground Detains both oil and sediment/silt, offering a combination of benefits not available in alternative dewatering bags Light, compact and easy to store Accommodates up to 102mm diameter discharge hose Single use only Material: 8 oz. Non Woven NOTE: To increase the efficiency of filtration, the bag can be placed on an aggregate or haybale bed to maximize water flow through the surface area of the bag
