Reverse Osmosis uses the principal of “osmosis” to produce high-quality drinking water
Reverse Osmosis is a process which forces a highly concentrated stream of dissolved salts through a semi-permeable membrane into a stream of purified water, known as permeate; and a stream of the removed highly-concentrated dissolved solids, known as concentrate or reject. Water pressure at typical pressure of 200 to 400 psi reverses the natural osmotic tendency of the solution, hence the term “reverse osmosis”.
The typical simplified Reverse Osmosis Plant consists of:
Typically of less than 5 micron rating.
Main feed pump
Multi-stage simplex or duplex pumps to generate osmotic pressure.
Membranes and Element housings containing reverse osmosis membranes
membrane housing interconnected with 316 stainless steel pipework.
Incorporating pressure gauges, flows, alarms, conductivity measurement and meters.
(Normally all skid-mounted for ease of installation)
The image shows a paint line rinse water package installed and commissioned by Cedek this plant replaced a 25 year old Demineraliser and has made considerable cost savings for our client in the amount of water used on the paint line rinse. This package is on a bimonthly service contract.
