How to extend the service life of the security filter element?

The better way to use the security filter element and the skills to extend the service life need to be formulated in response to its problems. First of all, we must know what factors affect the service life of the security filter element. The main factors that lead to frequent replacement of the security filter element: 1. The raw water quality is unstable and frequent fluctuations, resulting in too much particulate matter entering the filter element, resulting in a shortened cycle; 2. The pretreatment operation effect is poor, and the pretreatment dosing flocculation Agents, scale inhibitors, etc. are incompatible with each other or do not match the water source, and the formed sticky substance adheres to the surface of the filter element, resulting in a reduction in the effective filter area of u200bu200bthe filter element and frequent replacement of the filter element; 3. The quality of the filter element is not good, and the inner and outer pore diameters of the poor quality filter element Basically the same, in fact only the outer layer plays the role of interception, and the filter pore size of a good filter element is gradually reduced from the outside to the inside. The filtration accuracy of the inner layer is 5±0.5μm, the dirt holding capacity is larger, and the long time can be guaranteed. The effluent quality is qualified. Measures to prolong the service life of the security filter element: ①The water source is generally a fixed water source and cannot be easily changed; ②Improve the pretreatment operation effect, optimize the dosage of flocculants and coagulant aids, select scale inhibitors suitable for the water source, and adjust The pretreatment equipment reaches a good operating condition and strictly follows the requirements of the operating regulations to ensure that the pretreatment effluent quality is qualified.
