Function and purpose
In order to prevent the suspension particles that are not completely removed or newly generated in the pretreatment from entering the reverse osmosis system and protect the high pressure pump and reverse osmosis membrane, the filter element type security filter is usually set up before the reverse osmosis water. Generally, the aperture is less than 10μm, and it can be designed to be 5μm or lower according to the actual design situation.
component
The security filter is mainly composed of the filter shell, filter element, etc., the filter shell is mostly composed of R304 stainless steel material. If used in acid and alkali resistance and other special occasions, R316 stainless steel can be used as the shell. It can be divided into flange type and clamp type, and flange type shell is mainly used in the occasion of large filter flow. The filter element in the middle of the filter shell is mainly PP filter cotton core. In some cases, wire wound filter element or activated carbon filter element can also be used. The number of filter element installation can range from one to dozens, mainly according to the size of the processing capacity to determine.
