DRY ELECTROSTATIC FLY ASH PROCESSING FOR ACTIVATED CARBON RECOVERY

RESEARCH ON SEPARATION AND RECOVERY OF ACTIVATED CARBON FROMFLYASH, TOGETHER WITH RECOVERY OF AN ASTM-APPROVED CEMENT SUBSTITUTE USING ADVANCED ENERGY DYNAMICS' STATE-OF-THE-ART ELECTROSTATIC SEPARATION PROCESS IS PROPOSED. THIS PROCESS USES THE DIFFERENCES IN WORK FUNCTIONS OF PARTICLES OF DIVERSE COMPOSITION TO EFFECT A SEPARATION OF PROCESSED MATERIAL. IT HAS THE POTENTIAL OF TRANSFORMING FLYASH FROM AMAJOR POLLUTANT AND WASTE DISPOSAL PROBLEM INTO COMMERCIAL PRODUCTS, USING A DRY, LOW-COST, ENVIRONMENTALLY ACCEPTABLE METHOD. THE RECOVERY OF A LOW-COST ACTIVATED CARBON PRODUCTHAS THE POTENTIAL TO ALLOW ECONOMIC IN SITU TREATMENT OF CONTAMINATED GROUND WATER. MANY OTHER WATER POLLUTION PROBLEMS COULD BE IMPROVED WITH LOW-COST ACTIVATED CARBON.
