If we purchase an edi pure water equipment, the cost will definitely be considerable, so we must consider its advantages and characteristics comprehensively before deciding how to choose. Generally, how long can such equipment be used?

When using EDI pure water equipment, attention should be paid to the following aspects: before using EDI pure water equipment, clean the water inlet channel first, and be sure to clean it with filtered water, otherwise it is very likely to cause debris and dirt from the pipeline to enter the control module, damaging all machinery and equipment. Manipulate the strength of water seepage. If the water seepage intensity exceeds 0.5ppm or there are other conditions that cannot meet the target value, the emergency operation will damage the control module. Methods such as timely acid cleaning and softening of the concentrated water pipeline can be used. Regularly inspect the seepage water body of the control module to ensure that it meets the specified indicator values, such as checking the permanganate index or other reducing agents in the water.

The principle of ion exchange membrane in EDIro reverse osmosis pure water equipment is similar to that of ion exchange epoxy resin, which can selectively pass through positive ions. In this process, the anion exchange membrane only allows cations to pass through and does not allow positive ions to pass through; The cation exchange membrane only allows positive ions to pass through and does not allow cations to pass through. Filling a mixed ion exchange epoxy resin between a pair of anion and cation exchange membranes produces an EDI module.

Generally speaking, under all normal operating standards of pure water equipment, RO reverse osmosis membranes are also likely to be contaminated by inorganic compound deposits, colloidal solutions, microbial strains, hydroxides, and other environmental pollutants. These chemicals accumulate on the surface of the membrane, causing a decrease in the load rate or desalination rate of the pure water system, an increase in pressure difference, and even irreparable damage to the membrane. Therefore, in order to better restore good permeability and desalination characteristics, chemical water treatment must be carried out on the membrane. Generally, it should be cleaned every 3-12 months. If it is necessary to clean it once a month, it indicates that the preparatory processing system software should be improved and the main operating parameters should be adjusted. If cleaning is necessary every 1-3 months, it is necessary to improve the operational level of the machinery and equipment. It is difficult to distinguish whether it is necessary to improve the software of the preparatory processing system.

EDI is a pure water production technology that closely combines the technical aspects of ion exchange method, ion exchange membrane technology, and positive ion electrotransfer technology (electrodialysis technology). This technology utilizes ion exchange to remove salt from electrodialysis polarization, which cannot be completely desalinated. It also utilizes electrodialysis polarization to produce water ionization, causing H+and OH -. This ion continuously reconstructs ion exchange epoxy resin to maintain its good performance.

Throughout the operation of EDI pure water equipment, it is necessary to determine the total flow rate of various types of water, such as the total flow rate of water, the total flow rate of concentrated water discharge, etc. Only with sufficient total flow rate can the safety and normal operation of the linked equipment be guaranteed. Be careful when using plastic pipes and sockets, as these positions are relatively sensitive.
