    Industrial wastewater treatment and reuse

    Securing water supply is of high importance for many industries. Whether for use in breweries, pulp & paper, textile, electronics, pharmaceutical or cooling tower applications; water is indispensable. To put this into perspective, industry accounts for about 40% of total water abstraction globally. Many industries are located in water-scarce parts of the world, and more than two-thirds report on exposure to water risks for their business.
    With our direct nanofiltration technology, we enable:
    treatment of surface water and well water to remove color, humic acids, dissolved solids, organics, micro plastics and micropollutants in one single step;
    wastewater reuse for industrial processes or preventing discharge of polluted wastewater;
    recovery of valuable raw materials from wastewater streams, such as indigo in the textile industry or cleaning chemicals such as caustic in breweries.


    Treatment of wastewater can significantly reduce discharge costs and bring the discharge within compliance. Wastewater is becoming a valuable resource in many regions around the world and wastewater reuse will reduce the water footprint by reducing the raw water intake. Biologically treated waste water effluent is an excellent water source to treat with our direct nanofiltration membranes. In many cases waste water streams can also be treated directly with direct nanofiltration, resulting in a very compact and efficient reuse process.

    Wastewater treatment

    Municipal wastewater contains residues of household chemicals, body care products, pesticides and pharmaceuticals such as antibiotics and hormone-like substances. This group of compounds is generally called “micropollutants” and existing conventional wastewater treatment plants based on biological treatment are capable of degrading or removing them. As a result, they are commonly discharged into water bodies, like rivers, causing harm to the fauna and flora of these habitats. Further, these receiving water bodies are often the source of water for drinking water production plants which would similarly pass the micropollutants. Therefore, there is an urgent need to implement new technologies to further treat effluent from conventional wastewater treatment plants.

    Wastewater Reuse

    Micropollutants present in wastewater constitute one of the great challenges in water treatment. Pharmaceuticals and estrogens, along with personal care products, microplastics and surfactants present in greywater and wastewater effluent could lead to contamination of surface and ground water, soil, and even agricultural products if not eliminated. Many of these pollutants are not removed or even reduced by conventional wastewater treatment plants and therefore further treatment is required. NX Filtration hollow fiber nanofiltration membranes demonstrate high retention of low molecular weight organic compounds (including micropollutants) and are operated at low transmembrane pressures resulting in low operational costs in comparison with conventional membrane technologies.
