Industriewater Eerbeek (IWE) in the Netherlands, is responsible for the purification of the effluent from three different paper mills (approx. 4 million m3 of waste water per year). In summer 2018 IWE experienced a world first with a new decalcification process for reducing the calcium content of the effluent water. Now effluent can be reused as process water in the papier mills again. For both the pilot and the final full-scale decalcification plant, Landustrie supplied the LANDY surface aerators. The official opening of the new installation took place by State Secretary Mrs Van Veldhoven (Infrastructure and Water Management). In addition to these surface aerators, Landustrie earlier supplied a new LANDY screw pump for the influent pumping station and refurbished the clarifiers of the existing primary settling tanks.
