Washoe County, Nevada, conducted a five-week pilot test at the South Truckee Meadows Water
Reclamation Facility (STMWRF) to evaluate cloth-membrane filtration and sodium hypochlorite
disinfection in meeting state water quality regulations for unrestricted reclamation uses. Based on the
Nevada Water Quality Regulations, the targeted performance conditions for the filter included effluent
quality of total suspended solids (TSS) concentrations less than 5 mg/L and turbidity levels less than 2.0
NTU. The disinfection effluent quality standards included a maximum total coliform limit of 2.2 MPN.
Since the STMWRF supplements secondary effluent with diverted creek water to meet the local reuse
water demand, the pilot unit was operated in three modes: plant effluent only; blended effluent and creek
water; and creek water only. The pilot test results showed that, while the cloth-membrane filter unit
effectively produced filtered secondary effluent meeting the performance criteria, the unit was
unsuccessful in treating the blended and creek-water only conditions. Includes tables, figures.
