Laundry detergents and shampoo often include artificial surfactants in order to precipitate cleansing process. Since shampoo and detergents easily blend with tap water, they are likely to pollute water after being disposed into rivers. Considering the harm of artificial surfactant, this study is aimed to discover the malfeasance of artificial surfactants by mixing products containing artificial surfactant with river water and reducing the malfeasance. Measuring malfeasance rate is conducted by mixing experiment samples with tap water and river water from Han River in Seoul, South Korea. The standard for lower malfeasance and harmless product shows smaller negative deviation from the ORP rate and smaller positive deviation from the conductivity rate. Based on the result of the malfeasance experiment, the study about reducing malfeasance is conducted with blending materials for reducing pollutants such as citric acid, effective microorganism (EM), and egg yolk oil. Samples with EM showed the greatest effect in water purification process.
