Abstract


Diverse contaminations occurred such as water pollution. The developing nations experienced increase water pollution problems in these recent times. The discharge of untreated greywater in an uncontrolled manner to the main rivers is a key issue which pollutes the surroundings and causes unpleasant odours. Commonly, in village areas they discharge from the houses into the drains without any treatment.  It represents water that can potentially be intercepted at the household level for reuse. The purpose of this study is to establish a sustainable greywater treatment system in village house. The treatment system is aimed to provide simple and less maintenance for village household. Therefore, greywater was collected at the outlet pipe from the kitchen and bathroom using buckets with grabbing method at individual house Parit Hj. Rais. The treatment system consisting of sand, gravel and limestone in layer one; clamshell and ceramic in layer two and sand in layer three. The effluent was evaluated every week by using HRT 1 to HRT 4 day in 30 day treatment process. Besides, analyses of samples were collected from the outlet tank. The efficiency of greywater treatment achieves high percentage removal of BOD 98.04%, COD 97%, SS 99.24% and pH 6.60. The quality greywater parameters were accepted compared to previous study and standard of effluent discharge. Therefore, contaminant will be resolved by this treatment to avoid infectious diseases and pollution flowing into the drains. By increasing public awareness and upgrading the laws necessary to control the discharge of greywater in order to protect river systems from further degradation, exploitation and contamination is recommended.
