Abstract
WATER CURTAINS AND WATERFALL STRIPPING SYSTEMS ARE WIDELY USED IN PAINTING OPERATIONS. THE WATER USED IN THESE SYSTEMS BECOMES CONTAMINATED WITH PARTICULATES, PAINT SOLVENTS AND METAL IONS. CURRENT TREATMENT TECHNOLOGIES ARE INADEQUATE AND THESE WATERS HAVE OFTEN TO BE SENT TO HAZARDOUS WASTE TREATMENT FACILITIES FOR DISPOSAL. THIS PROPOSAL DESCRIBES THE DEVELOPMENT OF A COMBINED FILTRATION, REVERSE OSMOSIS AND PERVAPORATION SYSTEM TO TREAT SUCH WASTE STREAMS. THE UNIT WOULD USE A MICROPROCESSOR CONTROL TO SWITCH BETWEEN VARIOUS OPERATING MODES TO MAXIMIZE WATER RECYCLE AND NIGHT TIME USE OF THE TREATMENT SYSTEM. IN THIS WAY, A SMALL, ECONOMICAL SYSTEM COULD BE USED TO HANDLE THE FLOW PRODUCED BY A LARGE WATERFALL OPERATION. THE MAJOR TECHNICAL INNOVATIONS ARE THE USE OF A PERVAPORATION SYSTEM FOR VOC REMOVAL AND THE MICROPROCESSOR CONTROL UNIT.
