Coprecipitation Removes Trace Metals
Date: 6/905

Treating wastewater to protect the public and environment from pollutants has become an important issue for regulators and utilities. Reflecting this concern, effluent permits are becoming more restrictive, especially when EPAdesignated trace metals are present in electric power station wastewater. Given this situation, utilities have three options: treating the discharge, employing dry systems, or restricting systems to limited or zero discharge through recycling and reuse. When utilities want to maintain wet systems and discharge options, iron coprecipitation is an effective method to reduce trace metals to micrograms per liter. Moreover, iron coprecipitation costs 40% less than its leading competitor.
