Since 1979 HAR has gained extensive expertise in process and waste water applications, becoming one of the leaders in membrane separation technology. HAR systems are usually designed in close cooperation with customers from pilot plant trials, design engineering, construction through start-up. Over 10% of HAR annual revenues are devoted to the company’s research and development efforts.

The result is an on-going technological upgrading of its products and applications, and Oil-Water separation, solvent and catalyst recovery represent the latest developments.

According to the increasingly stringent environmental legislation, HAR designs and supplies complete plants "Zero Discharge Water Recycling", able to obtain purified water suitable to reuse or to discharge according to the law restrictions.
