Van Dalen Metals, Brabantse Delta.
At ground of metal processor Van Dalen Metals the contaminated rainwater must be treated . After rainfall, the water ends up in an underground pipe system. Through this system the water is separated to 2 E.S.A. Flexible Water Treatment Installations. Number 1 for Brabantse Delta stands on the front site of the property and number 2 for Rijkswaterstaat is standing on the back. The project what you see on the photo belongs to number1. Here the water is purified by means of a physical chemical reaction in the E.S.A. Reactor. After the treatment in the reactor, the water passes through a laminated filter. After this the water is ready and may be discharged into the sewer.
