Study of Liquid Waste Quality and Potential Pollution Load of Motor Vehicle Wash Business in Bekasi City (Indonesia)

摘要

The increasing number of motor vehicles in Bekasi city each year has led to the development of the motor vehicle wash business that can cause water pollution due to the resulting liquid waste. The use of various chemicals in these activities is one factor that affects the quality of liquid waste. This study aims to identify the quality of the liquid waste from motor vehicles wash in Bekasi city. The sample in this study was the liquid waste from the semi-automatic motor vehicles wash business in the North Bekasi region. The result of the research conducted in 3 locations showed that the processing of liquid waste produced was not carried out before being discharged into the environment. The results of test parameter presented in location 1, location 2, and location 3, respectively, were pH around 6.0, 5.0, and 4.8. TSS was 279.7 mg/l, 259.4 mg/l, 333.6 mg/l, COD was 657.1 mg/l, 182.1, 460.0 mg/l, oil and fat were 79.1 mg/l, 46.2 mg/l, 86.7 mg/l, phenol was 2.7 mg/l, 1.5 mg/l, 3.2 mg/l, and the highest potential pollution load was in COD parameter and TSS. Therefore, it is recommended that a motor vehicle wash business begins to pay attention to the impact of liquid waste by processing it before discharging into the environment and the Bekasi City government should begin to control water pollution, especially in those businesses.
