Implementing CCDTM Reverse Osmosis to Minimize Water Footprint

This presentation provides a general overview of the water issues surrounding the southwestern United States and sustainable measures that can be implemented to reuse valuable wastewater resources for agriculture and indirect potable reuse applications. As the growing population of the southwest moves inland, the need for maximizing water resources and minimizing wastewater generation is urgent. This paper focuses on a case study of a closed circuit reverse osmosis system operated by the Sanitation Districts of Los Angeles who independently documented and validated its performance. Operating reverse osmosis membranes in a semi-batch configuration rather than in a conventional once-through plug-flow configuration can reduce wastewater generation by up to 75%, significantly reducing overall water footprint.
