Abstract

FOR REUSING OF THE INDUSTRIAL WASTEWATER SHOULD DECREASE AMOUNT OF MATERIALS SUCH AS AMMONIA BECAUSE, THE AMMONIA CAN CAUSE CONNECTOR PIPES CORROSION. VARIOUS METHODS HAS BEEN USED TO REDUCE THE AMOUNT OF AMMONIA PRESENT IN THE EFFLUENTS; IN THIS PROJECT, WE WORKED ON TWO METHODS WHICH WERE BIOLOGICAL SEPARATION AND ION EXCHANGE RESINS (SORBENT SILICA-CONTAINING SOIL). IN BIOLOGICAL SEPARATION PROCESS, NEGATIVE AND GRAM POSITIVE BACTERIA THAT WAS CAPABLE TO CONSUMPTION OF AMMONIA FOR PROVIDING NEEDED NITROGEN AND ANOTHER ONE WAS ADSORBENT SILICA-CONTAINING SOIL WITH SPECIFIED MESH. WE FOLLOWED PROGRESSION OF EACH PROCESS BY SAMPLING AND MEASUREMENT OF AMMONIA THROUGH KJELDAHL PROCEDURE. THE LAST SATISFACTORY RESULTS WERE ACHIEVED BY USING ION EXCHANGE RESINS WHICH AMMONIA CONCENTRATION CAN BE REDUCED FROM 300 PPM TO 1 PPM, OF COURSE CAPACITY OF COLUMN CONTAINING ADSORBENT SILICA-CONTAINING SOIL IS LIMITED HOWEVER UTILIZATION OF THIS METHOD HASN’T BEEN LIMITED DUE TO OTHER SIDE BENEFITS ASSOCIATED WITH THIS METHOD SUCH AS MAKING CONCENTRATED COMMERCIAL AMMONIA SOLUTION; ON THE OTHER HAND THE NEXT METHOD IS ALSO PREFERABLE BECAUSE THESE BACTERIAS ARE EASILY ACCESSIBLE BUT THE LIMITING ASPECT OF THIS METHOD IS DURATION OF ITS FULFILLMENT; IN THIS STUDY APPLYING A SPECIAL SORT OF BACTERIA TOOK ABOUT 5 DAYS TO ATTENUATION THE CONCENTRATE OF AN INDUSTRIAL SPECIMEN FROM 300 PPM TO 17 PPM.
