How to improve RO membrane efficiency with CMF?
RO membranes may be subjected to particles and organics that foul the membranes due to the properties of sea water. It should come as no surprise that our climate is constantly changing; new discoveries suggest that this change in climate has generated many red algal blooms in diverse places. Algal blooms, like other particles in water, are extremely problematic for RO membranes. Contaminants like this must be eliminated before they hit the final desalination membranes, or else the membrane will fail.
What distinguishes cross-flow micro-sand filtration (CMF) in terms of pre-treatment capabilities?
Cross-flow micro-sand filters are made out of pressure containers filled with fine silica sand and utilising cross-flow hydraulics. CMF generally runs at speeds ranging from 30 to 60 m/h while removing submicronic particles. They are compressed mono-media filters that are used as dead-end filters.
What distinguishes this technology is its filtering capability, which removes tiny material down to submicron levels while maintaining a small and compact footprint. The modular architecture of the technology allows for the addition of many units at a later date, horizontally and/or vertically. Beachfront property is expensive, therefore a solution that lowers the need for further building and land acquisition might make future growth easier.
RO membrane efficiency with cross flow:
Employing a membrane pre-treatment system that satisfies your requirements will assist you in:
• Lowering operating and maintenance expenses
• Extending membrane life
• Creating high-quality water at a higher flow rate
• Reducing downtime by eliminating unexpected treatment failures.
What is actually the CMF technology?
Certain filters have a filtering diameter cut-off of 20 to 30 microns. Even when a chemical additive is used, the best outcome is the elimination of particles as small as 10 microns. CMF technology has a cut-off diameter so narrow that it eliminates particles as tiny as 0.5 microns in size. This same CMF technology is a slightly elevated filter that removes small particles that quickly clog the RO membrane. The CMF technology is a highly efficient filter, removing those fine particles that rapidly foul the RO membrane.
Would current facilities be upgraded to use CMF for pre-treatment, even if space is limited?
Unquestionably!
CMF treatments make use of high-velocity filtering. To fit into a small space, the system is built with skidding equipment. The dimensions of a CMF system are 75% smaller than those of traditional media filtering systems. In the same application, a flow that would require four MMF filters may only require one CMF filter. Eventually, a water treatment facility may be able to be retrofitted with fewer units while increasing flow within the same footprint. The treatment plant could then manage higher flow rates while maintaining or improving water quality.
How might CMF pre-treatment benefit plant operations and maintenance?
According to the CMF investigation, the energy required to operate the filters is the same as that required to operate regular MMF filters. However, because CMF technology can filter tiny particles, it requires less energy to run the RO membrane system for a longer period of time. Some chemical feed components can be eliminated or reduced because CMF technology allows you to use fewer chemicals because they perform better in a healthier environment. Renewal of cartridge filters that protect the RO filters is also reduced, often by a degree or two.
