Treatment of Dug Well Water in Kubu Raya, West Kalimantan, with Electrocoagulation

Abstract Dug well water is one of the clean sources used in Kubu Raya Regency. However, through initial testing, physical and chemical qualities were inadequate to meet hygiene sanitation demands daily living following Regulation No. 32 Minister Health Indonesia 2017. Consequently, objective this study was examine treatment dug by electrocoagulation electrocoagulation-coagulation employing Poly Aluminium Chloride (PAC) as a coagulant with varying periods (45, 60, 75, 90 minutes). Increasing processing time enhanced pH TDS values while lowering color, turbidity, Fe, Mn metals. The value increased for treatment. Conversely, concentrations Fe metal, metal dropped, however, increased, exceeding threshold. Ultimately, more effective at reducing contaminants, measured advances efficiency pH, Mn.
