Dewatering of contaminated sediments
The dewatering technology of TenCate Industrial Fabrics delivers solutions with unique filtration and retention properties. High performance filtration fabric consists of a high strength woven fabric. This technology can be utmost helpful for applications as marine remediation, mining and mineral processing, power and utility processing, pulp and paper industries, and industrial, agricultural or aquacultural businesses.
Our dewatering technology allows excess water to drain through small pores in the fabric during containment of fine grain sludge, hazardous contaminated soils, or dredged waste material. The result is effective dewatering and efficient volume reduction of the contained sludge. The run-off water from the dewatering process can be reused or returned to native waterways.
After the final containment and dewatering cycle, the retained fine grained materials in the filtration tubes of TenCate continue to consolidate by desiccation, which allows residual water vapor to escape through the small pores of the fabric. The captured solids in the tube container can now be disposed of properly. This dewatering technology offers an environmentally clean and cost-effective solution to handling dredge material and industrial sludge. It can take place on site and without interruption to industrial processes.

(1) Polluted and contaminated sludge from e.g. rivers, mineral processing, agriculture, light industrial areas, wastewater treatment and paper mills.
(2) Polymer dosing unit where application specific - environmental safe - polymers are added to the sludge
(3) Mixing sludge and polymers
(4) Dewatering system: Clear effluent water simply drains from the tube into the dewatring basin and solids remain in the TenCate Geotube® dewatering system.
(5) Dewatering basin to collect the run-off water using TenCate Nicolon® impermeable coated reinforced geomembrane and TenCate Polyfelt® nonwoven to protect this membrane.
(6) The bottom of the basin is filled with a layer of gravel, TenCate Miragrid® is applied to prevent gravel from damaging the TenCate Geotube® dewatering system
(7) Clear filtrate water that in many cases is of a quality that can be returned to native waterways or can be reused.
