The term reverse osmosis comes from the process of osmosis, the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration if no external pressure is applied. In simple terms, reverse osmosis is the opposite of osmosis. It is the process of pushing a solution at high pressure through a filter that traps the solute on one side and allows the pure solvent to be obtained from the other side.
Reverse osmosis will remove most elements from a water source. We understand the critical nature of pure water to the process.
The reverse osmosis membrane is extremely fine and sensitive to fouling and contaminants. For this reason the pretreatment to and RO plant is critical. The supply water should be softened to eliminate the potential for scale fouling the membrane. The supply should then be filtered using fine sediment filters to remove debris and carbon filters to remove any chlorine, organics, taste, odours etc.. as seen on the above chart. RO membranes will be consumed by chlorine very rapidly if it is allowed.
Halpin & Hayward can manufacture specialized RO units for specific applications such as hospital implement autoclaves. These autoclaves have a pure, hot water requirement that must be delivered above a specific pressure. Our skid mounted unit comes prebuilt for ‘plug & play’ ease of installation. On the skid is all required pumps, pressure sets, the filtration and softening pretreatment, the RO system and a lagged, stainless steel hotwell. (maintained at >75ºc) (insert alternating pic of skid RO)
We also supply and fit all necessary Parts & spares, and other consumables.
Our Dublin warehouse holds stock of our most commonly used products and what we do not have in stock can be quickly sourced.
