There is increasing interest in the use of membrane processing of wastewater for reuse as industrial process water, groundwater recharge, and irrigation. Status reports are presented on six current projects. The 1 mgd San Pasqual, California facility processes municipal effluent for irrigation. The 0.2 mgd Vero Beach, Florida facility processes secondary municipal effluent for reuse as boiler makeup for a power plant. The 0.13 mgd Mexico City, Mexico facility will process secondary municipal effluent for reuse by a tree farm that will raise 30 million pine seedlings per year to reforest the region. The 0.75 mgd Livermore, California demonstration project will process municipal effluent for groundwater recharge and irrigation with proposed eventual expansion to about 6 mgd. The 0.05 mgd Scottsdale, Arizona pilot facility will process secondary municipal effluent for ground water recharge and irrigation with proposed full-scale expansion in stages to about 40 mgd. The 1.1 mgd Chandler, Arizona facility will process industrial effluent from a semiconductor chipmaking facility for reuse.
