REVERSE OSMOSIS

How reverse osmosis works

Applied pressure moves water across a semi-permeable membrane. A treated stream passes onward while a reject stream carries concentrated dissolved material to drainage.

• Membrane filtration
• Pre-filtration
• Post-filtration
• Storage where applicable
• Direct-flow systems
• Reject-water connection

System requirements

Feed pressure, recovery rate, drainage, electrical supply, available space and outlet demand determine whether a storage or direct-flow arrangement is appropriate.

Finished water and maintenance

Remineralisation may be specified for taste or application. Membranes and filters follow condition and manufacturer schedules, supported by routine servicing.
