摘要: ABSTRACTHousehold wastewater is originated from common people's activities and has a potential harmful impact on the environment if discharged directly without proper treatment. Toilet or black water (BW) contains urine, faeces, toilet paper flushing it majority of pollutants obtained single household. In this study, focus was BW treatment using chemical methods. The main goal current research to define possibility applicability conventional coagulants flocculants in direct vacuum-collected remove particles, organic matter phosphorous. After definition dosing ranges, based equivalent doses municipal industrial data, aluminium iron coagulants, polyelectrolytes (polymers with anionic, neutral cationic charge different molecular weights) their various combinations were tested well-known jar-test laboratory method to...
