Reverse Osmosis Treatment of Central Arizona Project Water for the City of Tuscon: Appraisal Evaluation

摘要

This report addresses the feasibility and estimated costs of reverse osmosis (RO) treatment of Central Arizona Project (CAP) canal water. The study was sponsored by the Science and Technology Program and Phoenix Area Office of the Bureau of Reclamation and by the City of Tucson. RO is a water treatment process that cleans and purifies water by using pressure to push water, but not dissolved salts and many other contaminants, through membranes. The low-salinity RO finished product water has economic benefits, including reduced corrosion of water fixtures and appliances. RO treatment provides public health benefits, including serving as an effective barrier for removal of waterborne microorganisms, such as cryptosporidium and giardia, and producing water that meets all primary and secondary drinking water standards.
