The direct discharge of bathroom greywater (BGW) into water bodies without any treatment which contains xenobiotic organic compound (XOCs) due to the consumption of personal care products (PCPs) caused escalating concentrations of a broad range of pollutants in water bodies. Therefore, the aim of this study is to determine the type of physiochemical and XOCs in greywater result from the PCPs use in BGW. Next is to evaluate the efficiency of solar water distillation (SWD) to treat the bathroom greywater. The sample were taken from the direct discharge of Residential collage of Tun Fatimah bathroom activity, and treated with SWD to compare the concentration of greywater before and after the treatment. Based on Gas Chromatography Mass Spectrometry analysis, Methyl paraben was found in the BGW. Whereas the concentration before, 150 mg/L and after treatment by using SWD decreased to 80 mg/L. For the greywater quality, the highest removal percentage for Biochemical Oxygen demand (BOD) is 62.3%, while for Chemical Oxygen demand (COD) is 81.41%. The peak percentage removal of Total Suspended Solid (TSS) is recorded at 46.15%. It is worth mentioning that bathroom greywater pH ranging from 6 – 7 which is neutral. Lastly, Dissolved Oxygen (DO) show a positive result which is in the range of 6 – 8 mg/L. The findings prove that the treatment of greywater using SWD technique can enhance the quality of greywater.
