Evaluation of the New Compressible Medium Filter at Higher Filtration Rates for Unrestricted Water Reuse Requirements

Because a high quality effluent is produced after filtration of secondary effluent, the potential for reusing treated effluent is being examined by a number of agencies. In California, before treated wastewater can be reused, certain water quality criteria, set by the California Department of Public Health Services (CDPH), must be met. The filtered effluent turbidity must be less than 2 NTU (24 hour average value) as specified in the Title 22 Water Recycling Criteria for unrestricted wastewater reuse applications. The CDPH evaluates the available filtration technologies and issues Title 22 approvals for systems meeting the required performance criteria.
