EDR technology produces low salinity irrigation water from reclaimed municipal wastewater

摘要

San Diego sells more reclaimed water for irrigation by expanding the electrodialysis reversal system (EDR) capability in its municipal wastewater reclamation plant. Advantages such as 85% water recovery rates, no need for chemical additives tofeedwater, and fully pre-assembled trailer EDR systems helped city officials to opt for Ionics' solution. The US city of San Diego, California, shares a common problem with many other Western cities — not enough readily available water supplies. Continuous growth is making the supply of adequate water in the future an even greater challenge.
