Ultra Filtering of Organically Loaded Wash Water prior to Reverse Osmosis

Project Brief

Ultra filtering membranes where used instead of media filter for the more challenging and slightly organically loaded wash water. This, to make it suitable for reverse osmosis and for re-using as a utility type water.

Project Benefits:

• Prevents disposal costs to drain and additional borehole extraction costs
• Total organic carbon of water was approximately 200 TOC
• After pre treatment with ultra filtering membranes, the result was marginally dirty water to be cleaned by RO
• 50 to 60% recovery between the UF and RO filtering
