The application of ionization technology to reduce water pollutant level of domestic wastewater

Abstract

Increased human activity in households leads to an increase in the amount of wastewater. Domestic wastewater comes from organic matter, namely food waste and detergents which contain high total suspended solids phosphorus (TSS), chemical oxygen demand (COD) and biological oxygen demand (BOD). This can reduce environmental quality if the waste is disposed of directly without prior treatment. one of the treatments is by applying ionization. Ionization technology is used in the treatment process by using ions, high energy electrons, and active species to remove color and organic compounds through the flow of direct current (DC) from the anode to the cathode. This series of studies connects ionization technology with contact times of 30 and 60 minutes with an electric voltage of 20 kV which aims to reduce the level of wastewater pollutants in the Tunjungsari 2 Tembalang boarding house. Among the analyzed wastewater parameters, we succeeded in reducing wastewater pollutants, namely TSS removal reached 54.85%, BOD 85.99%, COD 79.45%, ammonia 55.06%, fatty oil 78.77%, total coliform 85.71% and pH conditions increased in value up to 54.38%. For optimal results, it is better to improve the ionization technology series from procedures to analysis.
