Plants of our Envopur®  product line cover the full range of membrane separation processes for water treatment, recirculation and effluent treatment. They are suitable for most types of industrial process water and have proved robust and versatile during many years of operation.
Often efficient solutions can only be realized by combination of different treatment processes. We offer a variety of processes. Dependung on your specific application we combine the following processes to achieve the optimum customer solution: e. g. Envopur® in combination with physico-chemical processes, biological processes or we combine different membrane processes.
Membrane filtration is the selective separation and concentration of dissloved as well as non-dissolved substances from the feed under pressure. The pore size of the membrane determines which molecules pass the membrane. According to the type of the feed and the required degree of purification specially membrane types are used.
