In an effort to increase plant efficiency and recover more product water while reducing sewer
discharge of concentrate waste and associated sewer fees, Irvine Ranch Water District (IRWD) evaluated increasing the overall
system recovery of its Deep Aquifer Treatment Facility (DATS). The DATS, an 8-mgd (30280m<sup>3</sup>/day)
nanofiltration (NF) plant utilizes a negatively charged, organic selective membrane that was specifically
manufactured to remove natural color causing organics with low salt rejection. To increase the current
system recovery of 92 percent, a pilot study was conducted to evaluate treatment of the concentrate
waste stream with ultrafiltration or nanofiltration membranes. This paper presents an overview of the
pilot test, membrane selection process, and results. Includes 5 references, tables, figure.
