Reverse osmosis (RO) is a method of producing pure water using membrane separation technology to remove all particles, molecules and ions from water. It is often used in desalinization plants, boiler make up water, and many other applications where any water impurities can cause fouling or deposits that can interfere with normal operation.
Because RO’s are designed specifically to operate at a given temperature, colder water will be thicker and can cause a decrease in flow capacity. There is roughly a 3% loss of product flow for every degree F the system operates at lower than the designed operating temperature.
A solution to ensure that the RO is consistently operating at its designed capacity is to use a direct steam injection Hydroheater for inlet water temperature control. By using internally modulated direct steam injection, a Hydroheater can keep the inlet water temperature at ±1°F of the set point so the RO can operate at the designed capacity without wasting energy over heating the water.
