Reverse osmosis is an established water purification technique which exploits the properties of natural processes to purify water. It utilises a semi-permeable membrane which allows water to cross but prevents other components of a liquid. RO water treatment removes molecules and ions from impure water and is vital in many applications important everywhere from laboratories to industrial factories.
How Does RO Water Treatment Work?
In RO water treatment, an applied pressure is used to overcome osmotic potential and force water molecules from an area of high solute concentration to an area of low solute concentration (which is the reverse of natural osmosis). RO water is generally considered to be the output of a reverse osmosis machine that utilises an RO membrane. It can also refer to the water that is'rejected' by the membrane which is commonly reused as feedwater to improve system efficiency. Membranes used in reverse osmosis purifiers have varying pore sizes, although most pore that are less than 1nm in diameter will remove at 90% of ionic contamination. Membranes are most commonly composed of a thin polyamide film that is stable over a wide pH range.
Veolia Water Technologies offer a range of RO water systems including the latest RO, UV, deionisation and recirculation technology to ensure maximum purity of treated water. The RO water process has an exceptional purifying efficiency and is a cost effective way to purify water.

What Are the Benefits of RO Treated Water?
RO water has many benefits over water produced using other purification methods, the most significant of which is that it effectively removes contaminants such as colloids, pyrogens and salts. What's more, it doesn't leave any residual materials like other water treatment techniques, e.g. chlorine disinfection. It is, however, advisable to pre-treat RO feedwater to prevent contaminants damaging the RO membrane.
