SAFE, COST EFFECTIVE ALTERNATIVES TO CHLORINE TREATMENT OF DRINKING WATER FOR DISTRIBUTION AND DISINFECTION HAVE BEEN SOUGHT FOR SOME TIME. CHLORINE DIOXIDE IS A VIABLE ALTERNATIVE TO CHLORINE FOR THE TREATMENT OF EVEN POOR QUALITY WATER SUPPLIES AND THE REDUCTION OF POTENTIAL CANCER CAUSING CHLORINATED ORGANICS. ITS WIDESPREAD USE HAS BEEN INHIBITED BY THE COSTS AND/OR COMPLEXITY OF ITS PRODUCTIO ...

THERE ARE NUMEROUS INDUSTRIAL PROCESSES REQUIRING THAT MATERIAL BE HEATED AND THEN SUBSEQUENTLY COOLED. IF MOST OF THIS HEAT IS RECOVERED AND RECYCLED TO THE OVEN, THE NET POWER INPUT TO THE OVEN COULD BE SUBSTANTIALLY REDUCED. THE KEY TO ACCOMPLISHING THIS IS AN INCREASE OF THE HEAT TRANSFER COEFFICIENT BETWEEN GAS AND MATERIAL SO THAT THE HEAT EXCHANGERS ARE RESASONABLY COMPACT. SIMPLE EXPERIMEN ...

RINSE WATER AND OTHER AQUEOUS WASTES FROM METAL FINISHING OPERATIONS PRESENT A DISPOSAL PROBLEM BECAUSE OF THEIR HEAVY METAL AND AGGRESSIVE CHEMICAL CONTENT. GENERALLY, THESE WASTES ARE TREATED CHEMICALLY TO PRECIPITATE THE METALIONS AS OXIDES OR HYDROXIDES. THIS TREATMENT IS COSTLY BECAUSE IT INVOLVES THE ADDITION OF CHEMICALS, DISPOSAL OF SLUDGE WITH LOSS OF VALUABLE METALS, AND LOSS OF THE HIGH ...

Electrokinetic remediation of metal contaminated soils is a promising in-situsoil remediation technology. In electrokinetic soil remediation, a current isapplied to two electrodes buried in the soil and the ionic contaminants movetowards the electrodes for subsequent cleanup of the localized contaminant.However, implementation of electrokinetic soil remediation is prohibited by1) buildup of a pH ...

The objective of Faraday Technology's Phase I program is to demonstrate thefeasibility of a novel treatment technology for in process recycling ofwastewaters generated by the printed wiring board (PWB) and metal finishingindustries. Specifically, their electrochemical ion-exchange (EIX) process willenable in-process recycling of both water to rinsing operations and metal saltsto plating operation ...

OVER THE LAST SEVERAL YEARS, THE EPA HAS DEVOTED MAJOR EF- FORTS TO IDENTIFY AND DOCUMENT THE MAGNITUDE OF THE RISKS OFENVIRONMENTAL POLLUTION DUE TO LEAKING UDERGROUND STORAGE TANKS (UST). IN APRIL 1987, THE EPA PUBLISHED THE PROPOSED REGULATIONS FOR THE OWNERS AND OPERATORS OF UST, WHICH ARE EXPECTED TO BE FINALIZEDD IN EARLY 1988. THESE REGULATIONS INCLUDE REQUIREMENTS FOR TANK TIGHTNESS TESTS, ...
