Treatment of laundry wastewater (LWW) using different filters media

Abstract

In this study, the reuse of household wastes as filter media was explored for treating laundry wastewater in addition to
sand media. These wastes included walnut husks and aluminum foil used in pharmaceutical drug packaging. For eight days,
the filtration system operated at flow rates between 0.02 and 0.04 m3/h. PO4, TDS, and TSS were the variables examined.
The results demonstrate that compared to sand and walnut husk filters, aluminum foil filters were more successful in
removing phosphate, total suspended solids, and total dissolved solids. The results showed that the wastewater's pH is
naturally alkaline, measuring at 7.8, which is the typical guideline value for laundry wastewater. TDS and TSS values
ranged (10400-8600) mg/L higher than the permissible limit. Maximum removal efficiency values were (72.55%, 49.67%,
and 78.48) for (PO4, TSS, and TDS) respectively for flow rate of0.02 m3
/h were accomplished by the suggested new
aluminum foil filter.
