Suspended solids and colloidal materials in feed water are one of the biggest problems in reverse osmosis systems. Even though most systems have some pretreatment including 5 microns pre filters, these fine particles are responsible for fouling of reverse osmosis membranes In order to have some measure of the degree of this fouling problems, a concept called silt density index is used. Here a 0.45 microns filter is exposed to the feed water under pressure and filtration rates are calculated. A detailed description of the test is available in our operating manual. *500 ml. measuring beaker and 0.45 micron filter paper.
