Like normal Reverse Osmosis processes, OARO uses a high-pressure pump to drive desalinated water through the membrane, by overcoming the osmotic pressure differential between the feed and the permeate side.
The system operates at RO (Reverse Osmosis) pressure resulting in low power consumption versus other traditional methods, and producing desalinated water and near saturation brine, which can be crystalized into high purity salt at competitive prices.
The osmotic-pressure differential between the feed and permeate sides allows continual concentration of ultra-saline feeds at pressures lower than 70 bars, meaning OARO’s maximum recovery is not limited by the burst pressure of standard RO membranes.
