How do I know if pretreatment will be required in front of a reverse osmosis (RO) system being used for boiler feed water?
A common oversight in designing reverse osmosis systems is the Silt Density Index of the water to be fed to the RO system. RO membranes have a fine porosity and are susceptible to fine particles called silt which may not be apparently visible. This is a relatively simple and short test that can prevent frequent RO membrane cleanings and even membrane fouling. It is especially important to test river water and is also recommended to test city water intended to be used for boiler feed water. Once the silt density index is known, an experienced water treatment company or consultant can recommend the type of pretreatment that will be required.
