There is no fixed time for how often the filter element of the security filter should be replaced. It mainly depends on the actual use. When the water quality decreases significantly, the filter element needs to be replaced. If you have to say how long it takes to replace it, it is about 3-6 months.
The security filter is equipped with a precision filter element. The security filter element generally adopts external pressure type. Water passes through the tiny pores of the filter element and enters the center tube of the filter element to discharge water. The micropores intercept the fine impurities in the water quality. The impurities intercepted are mainly determined by the pore size of the filter element. The filter element needs to be replaced after a period of use.
How often the filter element of the security filter is replaced, and the service life of the precision filter element is not a fixed time. How long it needs to be replaced depends mainly on whether it is standardized during use and whether it is well maintained.
Generally, the filter element needs to be replaced in the following situations:
1. The filter element is deformed or damaged;
2. When the filtration accuracy of the precision filter is reduced and the water outlet requirements are not met
3. The water output of the system does not meet the standard, etc.
The general reasons for frequent replacement of security filter cartridges are:
1. The raw water quality is unstable and fluctuates frequently, resulting in too much particulate matter entering the filter cartridge, causing the cycle to be shortened.
2.The pretreatment operation effect is poor. The flocculants and scale inhibitors added in the pretreatment are incompatible with each other or do not match the water source. The sticky substances formed adhere to the surface of the filter cartridge, resulting in the effective filtration of the filter cartridge.
3. The quality of the filter cartridge is poor. The inner and outer apertures of the poor quality filter cartridge are basically the same. In fact, only the outer layer plays an interception role. The filtration aperture of the good filter cartridge is gradually reduced from the outside to the inside. The inner layer filtration accuracy is 5±0.5µm, the pollution holding capacity is larger, and the water quality of the outlet can be guaranteed to be qualified after a long time of use.
