“In the field of water treatment, RWB is a valued partner. In particular, the available knowledge, short lines of communication and direct contact with the RWB (service) employees are of added value in order to guarantee the continuity of our installation.

The mechanics know the installation, ask the right questions have all the parts available to act immediately. Many companies can supply a water treatment installation, but RWB has specific knowledge in-house to provide a cost-efficient and reliable installation. When necessary, swift and appropriate action is taken to ensure our business continuity.”

“One of the most important water-saving projects in 2017 is the recovery of backwash water from the existing water treatment plant. Previously, this backwash water (from the sand filters for the removal of iron and manganese) went directly to the biological wastewater treatment plant as cold water.

This year we have decoupled the process. The backwash water is now treated by means membranes and then reused. This does not only result in a water saving of at least 0.1 hectoliters (3%) per filled hectoliter of packaged beer, but the waste water is also stabilized in temperature. This will allow the existing anaerobic reactor to function better. This results in a larger part of organic load. In other words, an increased biogas production of 2%.”
