What is reverse osmosis and how is it best used?

In wastewater treatment, reverse osmosis is a water purification technology that, like ultrafiltration, uses a semipermeable membrane to remove larger particles from drinking water. But in reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential, a thermodynamic parameter.

Using cold boiler feed water for energy recovery

Feeding membrane deaerated cold boiler feed water to appropriate units will enable waste heat to replace substantial steam duty in a refinery
Steam at different pressure levels is used for many purposes in refineries, including power production (steam turbines), heating, steam tracing, stripping, atomising and deaeration.
