The relationship between company Dow Deutschland Anlagengesellschaft mbH (DOW) with its underground brine chamber sites around Ohrensen, Germany and Reinhart Hydrocleaning SA (RHC SA) is a success story in itself. Prior to explaining the different ways of mechanical cleaning brine pipelines one has to know that RHC SA has worked with DOW since 2007 providing cleaning solutions for different pipelines. Approximately 91 km of DOWs’ pipeline network in the area around Ohrensen is cleaned by RHC SA.
