What factors affect the resistivity of EDI ultrapure water equipment? Author: With the advancement of the industry, demand for water equipment more widely, but pure water equipment during operation, as affected by a number of factors, which led to water quality not up to standard. Today, the editor of environmental protection will talk about the factors that affect the conductivity of EDI ultrapure water equipment.  1, the change of water temperature  The reverse osmosis membrane is one of the important parts of ultrapure water equipment. Generally, the water temperature of the inlet water is about 25 degrees. When the equipment is used in winter, the water temperature will be relatively low, and the water filtration capacity will gradually decrease after the reverse osmosis membrane is put into use, so the demand for water production must be enlarged to 1.5-2 times the nominal water production of the equipment when purchasing.  2. Changes in water quality   The changes in the quality of the incoming water will also lead to changes in the electrical resistivity of the pure water equipment. For example, the decrease in the quality of the incoming water will result in an increase in electrical resistivity, which will affect the water outlet effect.  3, pretreatment    pretreatment is to remove impurities in the incoming water, such as particles and other objects, these impurities will affect the service life of the reverse osmosis membrane and other accessories, and will also reduce the water outlet effect.  4. Reverse osmosis membrane    The reverse osmosis membrane of the equipment needs to be cleaned in time, otherwise once the impurities on the reverse osmosis membrane exceed the standard, the accessories of the equipment will be damaged over time and the conductivity will increase.   The above is about several reasons that affect the resistivity of EDI ultrapure water equipment. If you don’t understand, please consult the editor.
