With the increasing car wash businesses in urban areas and cities in Nigeria, there is an increase in the volume of wastewater generated from these carwash sites. These wastewaters contribute to environmental pollution as they often found themselves flowing into the environment without any control or modifications. This study aimed to develop a simple and efficient treatment process for carwash wastewater based on coagulation and flocculation using natural coagulants namely Carica papaya dried seeds and Aluminium sulphate (Al2(SO4)3,18H2O) in addition to a natural filtration system. The carwash wastewater samples were collected from different carwash sites located at Asaba, Delta State Nigeria. The management of the wastewater samples was planned prototype incorporating four phases namely: aeration, coagulation plus flocculation, sedimentation and filtration.
