TASK Industrial Environmental Techniques products

Industrial wastewaters from certain industries don`t meet the standards (eg. Vlarem in Flanders) for discharge, and certainly not for reuse as processwater. First of all, the toxic components have to be removed from the wastewater flow. Physicochemical wastewater treatment is a frequently used technique in the area of wastewater treatment. Physicochemical wastewater treatment techniques are applied for the removal of heavy metals, oils and greases, suspended matter and emulgating organic substances, organic and inorganic components, difficult to decompose non polar organic substances, toxic pollutants or high salt concentrations, phosphorus,... The physicochemical wastewater treatment techniques are used as pretreatment, final treatment as well as specific treatment for wastewater reuse as processwater.

Membrane technology - membrane filtration - water reuse - treatment and reuse of process water - degassing of liquids - membrane degasification. Based on the separative capacity of the membranes, there are mainly four different steps to be distinguished in the field of membrane filtration: microfiltration : separation of approx. 0,1 to 1 μm size particles (big proteins, yeast cells, microorganisms, …). Physical separation in function of membrane pore size. Possible applications in the field of wastewater treatment are e.g. : microorganism separation from wastewater, separation of oil/water emulsions, pretreatment of waste and process water prior to nanofiltration or reverse osmosis.
