Reverse Osmosis

RO is a membrane technology process that uses pressure to force a fluid through a membrane. It is the opposite of the natural osmosis function, in which a substance moves across a membrane from an area of high concentration to an area of low concentration. The process separates water from dissolved ions and compounds to form a clean stream (permeate) and a waste stream (reject). The RO process can reject up to 99.9% of viruses, bacteria, and pyrogens and up to 99% of dissolved ions and organic compounds.

Pre treatment requirements for RO systems depend on the feed water quality. Membrane life and cleaning frequency can be optimised with the correct up stream treatment regime. Puresep will assess the feed water quality and can advise on this – however typical pre-treatment options can include:

Puresep’s systems are modular skid mounted and compact in design allowing for future expansion. Process control systems for forward flow, re-circulation, process alarms and cleaning cycles range from manually operated control panels to PLC controlled plant with operator touch screen, SCARA interface and actuated valve assemblies – all implemented by Puresep’s engineers.
