Wastewater treatment

Taking responsibility for a valuable resource.

Water is used in the greatest variety of ways – as widespread as it is, that is how many applications there are. Our customers, too, have the widest range of requirements for water quality and for the measurement technology designed to ensure that quality. For this reason, we offer you individualized consulting, with the goal of always making the best possible selection of measurement technology. If customer-specific solutions make sense, we are able to develop them in consultation with you. Furthermore, we provide services such as system commissioning and maintenance contracts – anytime and anyplace.

Wastewater treatment – economical and efficient.

Optimally designed measurement and control systems make it possible to run sewage treatment plants efficiently while also saving costs. Auxiliary materials, such as chemicals used in precipitation reactions or neutralizations, can be dosed as needed and energy costs reduced, for example, in aeration for the biological treatment stage. Threshold values are thus reliably maintained, and sewage treatment fees can be reduced. In all areas of industrial or community wastewater treatment, KROHNE provides support for the optimization of your processes.
