Surface water generally contains impurities, on either a permanent or temporary basis. These impurities may be harmless, but the possibility also exists that they constitute a potential health hazard. Therefore, as a rule, multi-stage treatment processes are required to ensure that treated water is fit for human consumption at any time and does not cause problems during storage, distribution in networks, or various industrial applications.

In order to be able to guarantee an optimum solution for every specific problem, customised concepts are prepared using a wide range of process technologies (coagulation, sedimentation, flotation, filtration, ozonisation, activated carbon filtration, membrane processes, advanced oxidation, disinfection, etc.).
