The Indian Wells Valley Water District (District) in Ridgecrest, California, is located in the Mojave Desert about 150 miles inland from Los Angeles. As part of their planning for future water supplies, the District undertook a study to evaluate treatment of local brackish groundwater sources (TDS in the range of 1,300 to 2,000 mg/L). Pilot testin...

Direct, non-biological microfiltration (MF) of primary effluent has been tested at a number of locations over the last decade, including in the USA. Pilot testing of an MF system treating primary effluent was carried out at the City of Corona, CA, Treatment Plant No. 2. During th planned 4-month pilot test utilizing a Pall Corporation 0.1 micron Pv...

Recycled water projects that include some form of potable reuse are becoming more common in the water industry. They are being built to help alleviate water shortages throughout the world by allowing the reuse of available water. Many of these systems utilize membrane processes to remove soluble and insoluble contaminants to produce high quality pr...

Cal Poly Pomona, Carollo Engineers, Inc., and Pall Corp. are participating in a water reuse research funded by Bureau of Reclamation to evaluate novel treatment train ?integrated membrane anaerobic stabilization (IMANS)? system for wastewater treatment and water reclamation, the performance of microfiltration (MF) and reverse osmosis (RO) of primar...

This paper presents a successful story for optimizing the design of an industrial reuse facility using MF/RO/UV. Design parameters were established based on pilot testing and engineering evaluation. However, the sizing of the MF / RO system and the feed and product tanks becomes very challenging due to site restrictions and the dramatic variability...
