Equipment such as water softener, filter, EDI electric salt removal equipment 5 Edi water treatment module is an important part of ultra-pure water device,The purity of the water is directly affected by the operating state of the edi film block of the ionic water equipment,Therefore, regular maintenance and cleaning of EDI film blocks must be carried out,Ensure long-term stable operation of equipment.1. empty cleaning system.2. if the direct cleaning method is used,The EDI system cannot be emptied before or between the cleaning steps (if more than one step has been worked ).If recycling cleaning is used,Then drain the EDI system before or during the cleaning process (if more than one step has been worked ).3. import fresh water by closing EDI system,Fresh water exports,Fresh water flushing outlet,Concentrated water discharge,And the extreme water outlet valve separates the EDI system from the upstream and downstream.4. isolate the thick water pipeline from the fresh water and extreme water pipelines
What are the main performance indicators of air filters? Filtration accuracy refers to the maximum diameter of the impurity particles allowed to pass. The key to affecting the filtering accuracy is the filter element. different filter elements can be selected according to the needs of the following components to achieve the corresponding filtering accuracy. \ R flow characteristic refers to the relationship curve between the air flow through the filter and the pressure drop at both ends of the filter at a certain inlet pressure. in actual use, it is best to lose less than 0 pressure. selected within the range of 03MPa. In the air filter, the main factors that affect the flow characteristic are the body and the filter element. \ R water separation efficiency refers to the ratio of separated water to the water content in the air inlet. Generally, the water separation efficiency of the air filter is not less than 80%. the main factor affecting the water separation efficiency is the guide plate.
