Abstract-This research investigated three alternatives in recycling grey water from washbasin for reusing in toilet flushing system. Grey water were collected from all washbasins from 2nd floor to 9th floor of a 9 stories university building. The water were treated in three experiment systems in order to reuse in flushing systems such as men urinals and toilets. A recommended grey water treatment system is a set of a sedimentation tank, an aeration tank, a sand and carbon filtering tank, and a final sedimentation tank. Water quality after the treatment has SS, BOD 5 , and turbidity of 1.67 mg/l, 3.33 mg/l, and 3.33 NTU, respectively. Fecal coliform bacteria and E.Coli were not found in the treated water. Efficiency in reducing SS, BOD 5 , and turbidity are 90%, 78%, and 75%, respectively. In conclusion, grey water can be recycled and reused in flushing systems to use water more efficiently in buildings.Index Terms-Grey water, recycle, wash basin, and water efficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
