Abstract
DISCLOSED IS A SYSTEM FOR WASTEWATER TREATMENT FOR COMPLETE REMOVAL OF DIISOPROPANOLAMINE (DIPA) IN HIGH CONCENTRATION (UP TO 30,000 PPM). THE SYSTEM IS A PROCESS (100) FOR TREATING WASTEWATER (110) TO REMOVE A PLURALITY OF ORGANIC CHEMICALS HAVING HIGH ECOTOXICITY AND LOW BIODEGRADABILITY PRODUCED FROM AN OUTLET OF A REFINERY OR GAS TREATMENT PLANT (102). THE PROCESS (100) ACCORDING TO A PREFERRED EMBODIMENT OF THE PRESENT INVENTION STARTS BY PROVIDING A PHOTOCATALYST REACTOR (112) TO PERFORM THE PHOTODEGRADATION PROCESS. THE PHOTOCATALYST REACTOR (112) DECOMPOSES THE PLURALITY OF ORGANIC CHEMICALS INCLUDING DIPA. H202 (108) IS MADE AVAILABLE TO THE PHOTODEGRADATION PROCESS UNDER VISIBLE LIGHT RADIATION FROM A LIGHT SOURCE (106) FOR ENHANCING THE PROCESS OF REMOVING DIPA. THE SYSTEM SHOWED COMPLETE REMOVAL OF DIPA FOR BOTH SYNTHETIC (30,000 PPM DIPA, 55,050 PPM COD) AND ACTUAL WASTEWATERS (27,000 PPM DIPA AND 61,880 PPM COD) EMPLOYING THE 2-STAGE PROCESS USING MONOMETALLIC FOLLOWED BY BIMETALLIC PHOTOCATALYSTS IN THE FORM OF FE/TIO2 AND CU-FE/TIO2, RESPECTIVELY, WITH ADDITION OF H202 UNDER VISIBLE LIGHT IRRADIATION. TOTAL COD REMOVAL OBSERVED FOR THE SYNTHETIC AND ACTUAL WASTEWATERS WERE 80% AND 70%, RESPECTIVELY. THE TREATED WATER (114) HERE NEEDS TO UNDERGO BIODEGRADATION PRIOR TO DISCHARGE. THE TWO-STAGE PHOTODEGRADATION OF WASTEWATER WITH ADDITION OF H202 UNDER THE IRRADIATION OF SUNLIGHT AND AT AN OPTIMAL TEMPERATURE ABOVE ROOM TEMPERATURE TO BELOW 60°C AND UNDER A REACTION PH BETWEEN PH 8 TO PH 11 RESULTS IN ZERO RESIDUAL SLUDGE, SUSPENDED SOLID AND/OR ZERO RESIDUAL WASTEWATER FOR DISPOSAL. THE PHOTOCATALYSTS ARE SEPARATED FROM THE TREATED WATER BY ANY SIMPLE FILTRATION MEANS. MOST ILLUSTRATIVE DIAGRAM:
