Greywater traditionally receives the least attention compared to other aspects of environmental sanitation. In Malaysia, most of village houses discharged lots of significant portion of greywater into stream without any treatment. Laundry Greywater (LGW) is one of the largest portion of greywater that has been directly discharged to the stream. The aim of this study was to identify the physical and chemical characteristic of laundry greywater quality from the houses and also to evaluate the efficiency of using ceramic waste coarse aggregate filtration for LGW treatment. The effectiveness of the treatment systems was optimized with different Hydraulic Retention Time (HRT) and volume of samples by using Response Surface Methodology (RSM). The samples were taken from the direct discharge point of the laundry greywater at two houses. The results revealed that the efficiency of designed filtration system depended on HRT and volume of samples. The highest Chemical Oxygen Demand (COD) removal from 1 L of LGW and after 3 hrs was 43.31%, while the highest removal of orthophosphate (PO₄) (100%) and sodium (Na) (27.48%) were recorded with 2 L and after 2 hrs. It can be concluded that the ceramic waste coarse aggregate filtration was effective in reducing the pollutants in the LGW before the final disposal into the environment.
