This research program was initiated with the objective of bringing information concerning performance and cost of new wastewater treatment technologies to the attention of the metal finishing community. Many novel approaches to treatment of electroplating wastewater have been evaluated based on available information under an earlier effort. The most promising of these were selected for further investigation to include sampling, performance verification, and cost analysis. This report presents the results of that investigation for the three emerging technologies selected. The treatment methods included a system for treatment of electroplating wastes with ozone, a technique for chrome recovery by ion transfer, and a method of treating mixed wastestreams using ion exchange. Performance of each of these technologies was evaluated through sampling and analysis of prototype operation under normal production conditions. Performance data and cost projections for each system are presented herein.
