Abstract

The paper reports on a research program to evaluate the effectiveness of the reverse osmosis process in removing the contaminants with minimum of pretreatment of feedwater. The Las Gallinas Valley Sanitary District, Marin County, California, installed a 160-tube reverse osmosis (RO) unit for a pilot study on application of this process to renovation of municipal wastewater. The main objective of this research program was to evaluate the performance of the RO unit in renovating wastewater with minimum of pretreatment applied to the process. During the two-year study, the unit performed well considering large amounts of micro-biological and chemical impurities in the feedwater. The downtime for cleaning of membranes amounted to about 5 hours per week. Other interruptions in operation of the system were mostly due to external causes, such as power failures or malfunctioning of the multi-media filter pump. The product water from the RO unit is used for irrigation of landscaped areas, and as such, it must meet certain health standards based on the bacteria count.
