3 INFORMATION RECEIVED FROM BIO PURE COMPANY The treatment system proposed is a Bio-Pure extended aeration, complete mix, batch-reaction system manufactured by AquaClear Technologies, Inc. The Bio-Pure process has been certified by the National Sanitation Foundation (NSF) using the C-9 Criteria. A copy of the letter of certification is available upon request. The National Sanitation Foundation Basic Criteria C-9 test results were obtained using a production model of the Bio-Pure 30E secondary system. All subsequent production models, of all sizes, use the same process design. The similarity of the NSf test results and the actual results of the typical Bio-Pure plant effluent are nearly identical . Once the plant has stabilized (about 10 days after start up) , its performance is highly predictable. At secondary-level treatment, the pH ranges from 6. 8 to 7. 5 ; biochemical . oxygen demand (BOD) ranges from 6. 0 to 11. 5; dissolved oxygen (DO) ranges from 3 . 5 to 8 . 0; suspended solids (SS) range from 5 . 5 to 12, sludge volume in the SSV-60 tests will range from 80 to 380 mg/L, and fecal coliform counts will be less than 23 organisms per 100 ml. The system for this project will include pressure filtration and disinfection by both chlorine and ozone. With pressure filters and an ozonator, the Bio-Pure system will exceed State of California Title 22 requirements for reclaimed water for use as recreation or unrestricted irrigation water. California Title 22 is the most stringent water reclamation standard in the nation, and perhaps the world. It s 500 times more stringent than the equivalent standards set by the World Health Organization (WHO) . After system stabilization, the effluent will contain less than 10 mg/L biochemical oxygen demand, less than 10 mg/L suspended solids, and less than 2 . 2 coliform organisms per 100 m/L. The design goal of the system for this project shall be less than 5 mg/L each of biochemical oxygen demand and suspended solids and zero coliform organisms. With the ozonator, an output of zero biochemical oxygen demand, zero suspended solids, and zero coliform organisms is attainable. A copy of the AquaClear/Bio-Pure warranty is available upon request. The computer-controlled system operation is smooth and error-free. Once the field programmable unit is programmed, the operation will continue automatically and reliably until reprogrammed. The Bio-Pure system maintenance and testing (to meet typical NPDES permit requirements) will take less than 1. 5 hours daily and must be performed by a registered sanitarian or by a firm licensed to perform such testing and maintenance. The selected operators will receive a minimum of 8 hours of Bio-Pure system theory, training, and instruction by AquaClear Technologies. The Bio-Pure batch treatment process design for this project is
