The effect of electrochemical precipitation (EP) on tap water disinfectants is being investigated. Without the use of chemical additives, this procedure involves delivering electricity through electrodes submerged in water to precipitate dissolved metals, such as hardness. This study assesses the impact of EP on disinfectants in tap water. In addition to hardness, residual disinfectants found in tap water are essential for preventing possible pathogens from entering the water supply before they reach customers. Free chlorine levels in drinking water must be kept between 0.2 mg/L and 4 mg/L, according to USEPA regulations. The chemical makeup of chlorine species can change during the EP process due to pH variations close to the electrodes. In contrast to the sacrificial metallic cathodes used in traditional EP procedures, a newly created conductive concrete block is used in this work. Constructed from concrete, these blocks have conductive graphite flakes imbedded in them. The purpose of the study is to quantify the amounts of free and total chlorine in tap water under various treatment circumstances, including pH levels, chloride concentrations, current densities, and treatment times. Greater amounts of free chlorine disinfectants are found in water with greater chloride concentrations, longer treatment periods, and higher current densities, according to preliminary research findings. This study presents conductive concrete and EP as a novel way to eliminate hardness and maybe improve disinfection. It seeks to present early data demonstrating its effectiveness and value addition as a disinfection technology.
