Post-treatment

Reverse osmosis permeate can be corrosive, so Osmoflo has a number of technologies to improve its characteristics such as calcite filters to improve alkalinity and pH correction using degassing towers.

Osmoflo also design, build and operate demineralisation plants for boiler feed for industry and power generation using ion exchange resin systems and electro-deionisation processes.

Electro-deionisation (EDI)

Electro-deionisation of EDI, uses semipermeable membranes and Direct Current to purify water. The positively charged ions in the solution are drawn through the membranes towards the negative electric charge, and visa versa, leaving behind a purified water system.

One application for EDI is 'polishing' treated water to produce ultra high purity water, suitable for use in the semi-conductor industry.

Ion Exchange

Chemical processes such as ion exchange, where the water passes through high pressure vessels which use resins to absorb the dissolved salts, leaving behind purified water.

Ion exchange is used to treat relatively clean brackish water to produce high purity water for applications such as boiler feed in power stations, required to maintain heat transfer efficiency.

Water Sterilisation

After water has gone through the RO process, it is generally free of bacteria and other contaminants. If the water is for potable use it is generally stored in tanks before being used, making it susceptible to contamination. Chlorine Dosing and Ultra Violet sterilisation provide a reliable method to keep stored drinking water safe.
