In an effort to minimize their short and long-term environmental impact, industries across the globe are facing increasing challenges and costs in the treatment of their process wastewater.

As a result, many of these industries have built their own treatment systems in order to treat and reuse process streams, reducing discharge costs to municipal treatment plants and recovering valuable products from effluent.

Follow the Berghof Membranes project reference story commissioning for Holland Malt, one of the largest malt production facilities in Europe.
