Reverse Osmosis RO is widely applied for any desalination process. Even low concentrations of biodegradable organic compounds can quickly block a complete system by forming biofilms on the membrane, clogging the system. A common approach is an extenden mechanical pretreatment by ultrafiltration or the use of toxic chemicals to avoid any organic action.
The patented BiosS-Treat combines a precipitation step with a subsequent biological active filtration. This way, substances responsible for fouling are removed. This is supported by a soft dosing of chemicals. Results show a very reliable and safe operation of subsequent RO-units, even when SDI values are still high.
Different customers rely on this approach as a pretreatment to RO and have experience for several years. Plants are placed both in China and Europe.
