RPSEA Project 07122-12 TECHNICAL ASSESSMENT OF PRODUCED WATER TREATMENT TECHNOLOGIES 1st Edition Polymeric MF/UF membrane Polymeric MF/UF membranes are made from materials like polyacrylonitrile (PAN) and polyvinylidene (PVDF). Because there is a large market for polymeric ultrafiltration membranes, there are many vendors and suppliers for these membranes. They are also relatively inexpensive. Typically, package systems are purchased and installed by the vendor. An important consideration for polymeric MF/UF membranes is integrity testing to ensure that the membrane is not damaged and is operating properly. Typically, the filtrate turbidity is monitored to give a rough indication of membrane integrity. Membrane integrity can be tested through a pressure decay test. In this test, pressurized air is applied to the membranes at a pressure less than would cause the air to flow through the membrane, and the pressure decay is measured. Regular monitoring of membrane performance is necessary to ensure the membrane system is operating at the most effective loading rate and backwash regime. Membrane life is typically estimated at 7+ years with manufacturer warranties covering 5 years in municipal applications. Waste includes pretreatment waste, backwash flow, retentate flow (if applicable), and CIP waste. Waste streams are either discharged to the sewer or treated if discharging to surface waters. Waste streams being discharged to surface waters are typically processed for turbidity removal through settling ponds or other treatment systems. CIP waste is neutralized and usually combined with the rest of the waste. A summary assessment of polymeric MF/UF membranes is provided in Table 11. Table 11. Polymeric MF/UF Membrane Assessment Criteria Industrial status Feed water quality bins Product water quality Production efficiency (recovery) Infrastructure considerations Energy consumption Life cycle O&M considerations Description/Rationale Polymeric membranes are used extensively in the municipal water treatment industry. Applicable to all TDS bins, independent of salt type and concentration. Product water is free of suspended solids. DOC removal is approximately 10%. Nearly all non-dissolved organic carbon removed. 85% to 100% depending on feed water quality and mode of operation (dead-end vs. crossflow). A feed tank, feed pump, coagulant dosing pump, and rack structure for holding the membrane modules are required. Not available. 7 years or longer. Integrity monitoring is required. Chemicals Pre-coagulation may be used to enhance contaminant recovery. Doses usually range from 1 to 5 mg/L depending on water quality and the type of coagulant used. Common coagulants include polyaluminum chloride, ferric chloride, and aluminum sulfate. Chemical enhanced backwash may be used which would require the use of acidic and alkaline chemicals. Periodic chemical cleaning is required. Acids, bases, surfactants, and oxidants are commonly used. Overall costs Capital cost for polymeric ultrafiltration systems vary based on the size of the plant and feed water quality. Approximate capital costs will be near $1 - $2/gpd ($0.02 to $0.05/bpd) and O&M costs approximately $1 to $2/kgal ($0.02 to $0.05/bbl). 24PDF Image | TECHNICAL ASSESSMENT OF PRODUCED WATER TREATMENT TECHNOLOGIES
