Sludge Dewatering Tubes are manufactured from high strength permeable geotextiles with specifically engineered retention and drainage properties and then fabricated into a variety of sizes. Excess water drains through small pores in the geotextile while the sludge and sediment is retained inside the tube resulting in effective dewatering and efficient volume reduction of the sludge. This volume reduction allows for repeated filling of the dewatering tube. Often, the quality of the decanted water is such that it can be returned to native waterways. After repeated filling and dewatering cycles, the retained sludge and sediment material will continue to consolidate and dry. When your desired consolidation is achieved, dispose of your retained sediment in a landfill or by other suitable method.
