Treatment of Metal-Bearing Solids - Using a Buffered Phosphate Stabilization System

摘要

A pH-buffered phosphate chemical fixation process (patented), which has been used successfully at hundreds of uplands sites, has also been implemented at full-scale in sediment settings. With minimal engineering controls it is an economic, environmentally friendly, and robust process that can be applied in situ for lead-, cadmium-, and zinc-contaminated sediments.
