Water Reuse Study for Big Bear, California. Desalination and Water Purification Research and Development Program Report No. 154

摘要

Reverse osmosis (RO) and nanofiltration (NF) were tested using microfiltered municipal wastewater for producing water for irrigation and wetlands habitat. Vibratory shear enhanced processing (VSEP) was tested for high recovery of RO concentrate. NF concentrate had the best quality for irrigation. Product water from both NF and RO would be pure enough for wetland augmentation. Maximum recovery possible with the VSEP process was 93.5%. Cost estimates and preliminary design are provided for a 1-million-gallon-per-day ultrafiltration (UF)/RO and UF/NF system.
