Membrane Separation Systems/ Reverse Osmosis

Membranes in any membrane separation system are the heart of the plant and the process. The performance of an RO / UF membrane can be impaired by impurities that foul the membrane suface during operation. These foulants/impurities can foul the membrane and cause loss in production of clean water and hence reduce overall plant efficiency.

Fouling is attributed to (1) Scaling due to mineral deposits, (2) Fouling of suspended solids (3) microbial fouling or development of biofilm due to growth of bacteria in the system.

The performance of an RO plant can be improved by

Good pre-treatment to remove suspended solids, colloidal matter and other impurities

Chemical solutions.
