KAJIAN INSTALASI PENGOLAHAN AIR LIMBAH INDUSTRI ELEKTROPLATING YANG EFISIEN

In order to decrease the investation and operational cost of electroplating industry waste,study on various kind of electroplating indusfry waste water treatment technology is needed. Inthis research, the studied waste water treatment technology for electroplating industry was Physic-Chemistry Process conducted with the technology of Continuous Stream Tank with Stirring Rod and Ion Exchange Process with Fixed Bed Technology. This research aimed to yield an eflcient electropIating industry waste water treatment technology and process measured j?om it's operational cost aspect, and also the quality of treatmentproduct water which meets Waste Water Quality Smuimd. Research was conducted with physic-chemise process using FeS04 as reductor, NaOH and CU(OH)a~s precipitator. Process variables at FeS04-NaOH combinafion : acidity degree @H) : 5, 7, 9,11, dan 13; at FeS04&a(OH)2 combination : acidity degree (pH) : 5, 7,9, dan 11, and waste water low velocity : 200,400,600,800,IOOO ml/minute
