SUCCESS STORIES OF AN INNOVATIVE WATER RECYCLING METHOD USING CARBON ADSORPTION TO RECOVER HEAVY METALS FROM INDUSTRIAL WASTEWATER

摘要

The metal finishing and electronic industries are searching for ways to recycle materials and reduce costs. The areas of heavy metal waste and water recycling has gained new interests with the potential of impacting the operation's bottom line. Lewis Environmental Services, Inc. has completed numerous heavy metal recovery and effluent recycling projects with its ENVIRO-CLEAN PROCESS for government and private sector clients. This patented process utilizes a proprietary chemically treated granular activated carbon with enhanced heavy metal adsorption capabilities combined with electrolytic metal recovery to produce a saleable metallic product. The process generates no sludge or hazardous waste and the effluent meets EPA limits. This paper covers several heavy metal removal projects, two full-scale commercial installations, and one treatability case study.
