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.

“…Therefore, since BMED was incipiently adapted to practical industrial applications in the 1980s, there has been a large number of experiments conducted using this technology to extract resources from high-salinity wastewater [ 8 , 9 ]. Mohammadi Mariam rapidly separated ammonia from high salt wastewater via BMED technology and recycled it into ammonium hydroxide solution [ 10 ]. Arif Hussain designed a multi-stage intermittent process in a BMED process which can further increase the concentration of acids and bases prepared via BMED technology [ 11 ].…”

Actual high saline wastewater containing concentrated organics and sodium chloride is a bioenergy and renewable resource. This study compared two different bipolar membrane electrodialysis membranes from two companies’ stacks to recover HCl and NaOH from sodium chloride solution and actual chemical wastewater. The results demonstrated that the electrolysis rates were around 1.5 kg/m2h, the HCl and NaOH production rates were about 0.9 kg/m2h, energy consumption was in the range of 1.05–1.27 kWh/kg, and the economic benefits were above 1 yuan/h in BMED systems. From analyzing the performance of seven different BMED membrane stacks, the B2 stack was chosen for electrolyzing actual high salt wastewater to observe the effect of chemical oxygen demand on BMED systems, where electrolytic salt performance, HCl-NaOH alkali production rates, and energy consumption show linear dependence on time for 5000 mg/L chemical oxygen demand wastewater. It illustrated chemical oxygen demand can enhance energy consumption and reduce electrolytic salt performance and the acid and alkali production rates, due to improving the membrane area resistance. In this study, the effect of high COD saline wastewater on the performance of a BMED membrane stack was clarified and the mechanism was analyzed for its practical application in treating chemical high salt wastewater.
