FOURD  is a water treatment pharmaceuticals, equipment manufacturers, has many years of water treatment. Many users of reverse osmosis pure water equipment in the use of pure water equipment when there are a lot of incorrect place, resulting in shortened service life of the equipment. Today we are talking about pure water equipment in the use of the process need to pay attention to what matters.
1, precision filter is mainly used to remove the water and other large particles of sediment material, the new filter is white, with the use of time, will become brown, mainly because the filter above the retention of a large part of the dirt, Dirt will remain on the surface of the filter element. To change the filter regularly. Not timely replacement filter, the water quality will drop.
2, activated carbon is used to remove residual chlorine and odor in water, most of the cases, activated carbon is needed to replace once a year. In appearance above, activated carbon can not see the change.
3, reverse osmosis membrane, ultra-pure water equipment is the most important components. Most of the reverse osmosis membranes are used for 2 to 3 years.
4. To prevent the filter into the reverse osmosis device: select the appropriate filter effluent device to prevent the filter leakage leakage activated carbon; select the appropriate activated carbon, to prevent the use of the process of powder.
5. It is best to set up an independent water supply system for large pure water equipment with tap water as the source of water. This will ensure the stable operation of the water supply system and reduce the instantaneous impact of the RO system on the whole plant water supply pipe network. When the RO device directly from the original water pipe network, should be set up high and low voltage protection facilities, because most of the water pipe network pressure fluctuations.
6. First consider the compatibility between agents and pharmaceuticals, followed by pharmaceutical and membrane materials should consider the compatibility. For example, coagulants, coagulants, bactericides, reducing agents and scale inhibitors are often used in RO systems. Since colloids in natural water are generally negatively charged, positively charged cationic coagulants are commonly used. In order to prevent scaling of the R0 device, almost all of the inlet side of the RO has taken into account the measures of adding the scale inhibitor, which are almost negatively charged. Therefore, it should be avoided that the cationic coagulant reacts with the anionic scale inhibitor to prevent the formation of colloidal compounds from the reaction. The following are the same as the "
