Laundry Wastewater Characterization and Treatment for Reuse Purposes in Muscat, Oman

EasyChair Preprint 3063

Abstract

The present study aim and focuses on a comparative study for the cleanup of laundry wastewater characteristic from domestic and commercial sources in Muscat, Oman. The laboratory analysis performed to investigate the effluent quality parameter from commercial and domestic of laundry water for ten run cycles for the parameters of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solid (TDS), Total Suspended Solids (TSS), Turbidity, Electrical Conductivity (EC), Dissolve Oxygen (DO), Copper (Cu), Iron (Fe), Magnesium (Mg), Hardness, Temperature. Sand filter is used to upgrade the effluent quality to comply with the Omani standards for discharge of non-housed liquid waste into sewage system. Treatment of laundry wastewater by sand filter involved collection of wastewater in storage tank where the wastewater pass through the sand filter by gravity upon vertical system. The adequacy of the treated laundry wastewater was assessed by Caledonian College of Engineering (CCE). Commercial color cloths wastewater treated by sand filter shows the removal of approximately 30% for TSS, 70% for TDS, and turbidity 20%. The result of this study shows that all wastewater quality parameters, (pH, TSS, TDS, Turbidity, Electrical conductivity, Temperature, DO, Hardness, Fe, Cu, Mg) are complied with Omani standards for discharge of non-housed liquid waste into sewage system. As consequence, the discharge of the laundry liquid waste from commercial and domestic has no impact on the wastewater facilities in Muscat.
