In Reverse Osmosis water treatments, feed water is pumped at high pressure through permeable membranes, separating salts from the water. It is called Desalination of Reverse Osmosis (RO). The feed water is pre-treated to remove particles that would clog the membranes. RO membrane will purify water from almost all chemicals. What can pass through the RO membrane is water and molecules smaller than the water molecule.

FILMTEC™ RO Membrane

FILMTEC™ membranes provide highly effective technologies, such as reverse osmosis (RO) and nano-filtration (NF), FILMTEC™ membranes reject more dissolved solids and organics, and use less energy to produce permeate, than typical elements.

FILMTEC™ reverse osmosis membrane elements are very effective at industrial process water treatment plants. In many industrial systems, RO elements also serve as pre-treatment for ion exchange (IX) resin beds. FILMTEC™ RO elements that are installed before ion exchange beds, which help reduce demineralizer operating costs dramatically. The FILMTEC™ RO membrane elements that are used in double-pass RO systems, which produce high-purity water in a continuous process; for applications with less stringent water-purity requirements, these elements can be used cost-effectively in single-pass RO systems as well.

Application:

• Desalting of well waters for municipal drinking water supplies
• Production of boiler make-up water for power plants
• Municipal wastewater plants
• Industrial surface and waste waters
• Seawater desalting
