Preliminary tests are often required for the selection and design of new water treatment plants. For this  Weil Wasseraufbereitung GmbH can provide various rental facilities. Based on our experimental experience, we adapt these for every application, deliver the rental system and install it on site. After a briefing, the test facilities can be operated directly. By remote maintenance module, the company can. Because water treatment support the operation. The data obtained from the tests can then be used directly for the planning of the large-scale plant.
