Small town, high-tech solution

Article Abstract:

Toluca is a small community in Central Illinois, which uses the high-tech reverse osmosis system for producing potable water from source water with high total dissolved content, for the community water supply. The $700,000 system was established in Feb 1992 to ensure compliance with the Safe Drinking Water Act of 1986. The technique produces high-quality water at an economical rate of $2.50 per 1,000 gal. The system requires little operator attention, enables continuous monitoring of conductivity and pH, and includes a provision for automatic shut-down if inadequate water quality is produced.

Desalination facility tests three membrane technologies

Article Abstract:

A water treatment facility in Oxnard, CA, utilizes three desalination technologies in demineralizing the water, namely, nanofiltration, reverse osmosis and electrodialysis. Moreover, the plant will be used as a research facility that will compare the performance and costs of the technologies. The water treated by each membrane technology is mixed with water imported from the California State Water Project before its distribution to residents. The facility intends to supply cleaner and more potable water which is better than the perceived inferior groundwater supply.
