RPSEA Project 07122-12 TECHNICAL ASSESSMENT OF PRODUCED WATER TREATMENT TECHNOLOGIES 1st Edition been shown to be a highly efficient method for restoring membrane performance without the need for chemicals [72]. However, chemical cleaning and the addition of scale inhibitors may be required for both the FO and RO subsystems depending on feed water quality. The service life of an FO-RO system is currently unknown, however RO membrane elements will likely require replacement within 3 to 7 years of operation [36]. Industrial scale FO-RO systems would be highly automated systems, and would require relatively little supervisory oversight. The FO subsystem is capable of treating highly variable feed water qualities and protects the RO membrane modules from harmful membrane foulants. The system would require few major maintenance periods; however, the system would need to undergo brief, routine backwashing and mechanical cleanings several times each day. Optimization is underway. The FO component of an FO-RO system provides excellent pretreatment capabilities, while the concentrated brine generated from the RO system is continuously recycled in the system. The most significant waste stream that will require either further treatment or disposal is the concentrated feed stream. Additionally, the FO draw solution may require infrequent disposal and addition of a new draw solution as sparingly soluble solutes and other membrane foulants slowly accumulate in the draw solution reconcentration loop [92]. A summary of the technical assessment for an FO-RO system is listed in Table 21. Table 21. Summary of technical assessment of hybrid FO-RO system. Criteria Industrial status Feed water quality bins Product water quality Production efficiency (recovery) Energy consumption Chemicals Life cycle Description/Rationale One pilot-scale test on secondary effluent from a municipal wastewater treatment plant. No previous utilization for CBM produced water treatment. The estimated TDS application range is between 500 mg/L and 35,000 mg/L. High removals of monovalent and divalent ions, metals, and organics is expected. Treatment process permeate quality is dependent on feed water salinity and operating conditions. Pilot-scale studies report greater than 99% rejection of TDS in RO permeate. Product water recovery is estimated to exceed 96%. Energy requirements are estimated between 5.68 to 11.36 kWh/kgal (0.24 to 0.48 kWh/bbl) [91]. Chemical cleaning rates depend on feed water quality. Cleaning will typically occur after certain design specifications are exceeded, and may require the use of NaOH, Na4EDTA, or HCl. No data is currently available for hybrid system; however, RO elements will likely require replacement between 3 and 7 years of operation. Infrastructure considerations This treatment process will require a larger footprint that conventional RO systems. Chemical storage will be required, in addition to a FO membrane bank. System mobility is reduced compared to conventional RO systems. 55PDF Image | TECHNICAL ASSESSMENT OF PRODUCED WATER TREATMENT TECHNOLOGIES
