DHP RO High Pressure Pumps For All Possible Applications

Reverse Osmosis is a technology that is used to remove a large majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane. Commonly referred to as RO, is a process where you demineralize or deionize water by pushing it under pressure through a semi-permeable Reverse Osmosis Membrane. It is the process of Osmosis in reverse. Whereas Osmosis occurs naturally without energy required, to reverse the process of osmosis you need to apply energy to the more saline solution. A reverse osmosis membrane is a semi-permeable membrane that allows the passage of water molecules but not the majority of dissolved salts, organics, bacteria and pyrogens. However, you need to 'push' the water through the reverse osmosis membrane by applying pressure that is greater than the naturally occurring osmotic pressure in order to desalinate (demineralize or deionize) water in the process, allowing pure water through while holding back a majority of contaminants.

The high-pressure reverse osmosis applications we mentioned include environmental protection markets and seawater desalination. The environmental protection market refers to landfill leachate, zero liquid discharge (ZLD), Material Separation. These applications correspond to the DHP series RO high pressure pumps. Reverse osmosis is the process of turning sea water into drinking water. Typical desalination applications are on yachts and remote areas (e.g., islands). Our duplex/super duplex pumps generate the pressure needed to send the incoming salt water through the membranes and as a result drinkable water is separated from the salt water.
