Metal-working factories generate a lot of oily effluent as a result of manufacturing processes. The coolant emulsions tailored to the individual application contain oils, waxes, greases and preservatives, as well as a cocktail of ingredients to improve product properties. The emulsions used must not be discharged untreated into the drain system or open bodies of water; they must be disposed of at high cost.

TenCate Geotube technology dewaters primary, secondary and overflow sludge from the sewage treatment plants’ digesters and lagoons. This municipal dewatering solution is used in water and wastewater treatment applications including lagoons, tanks, and digester cleanouts. The containers can provide dewatering and containment in one operation, with 85% to 90% reduction of BOD in the effluent. Most of the time, the dewatered effluent is clear and safe enough to be returned to the sewage treatment plants.
