• Industrial water treatment

    The availability of process water plays an important role in industry since virtually every production process requires water. Whether it is for cooling, cleaning or as a starting material for aqueous solutions – depending on the application, the unwanted substances must be removed from the raw water or the desired substances added.

     

    This task is performed by water treatment plants, thus ensuring a functioning circuit. The GEMU product range can provide reliable solutions for components for measurement and control systems for these plants.

     

    A huge variety of valve types and automation components

    Durable, robust and optimised for their specific use: GEMÜ produces and supplies butterfly valves, diaphragm valves, globe and control valves, ball valves, as well as components for plant and plant sections for industrial water treatment.
