How often does the security filter element need to be replaced?

The security filter element actually needs to be replaced after a period of use. The replacement frequency of the security filter element is relatively frequent. Why? There are three main reasons: First, the raw water quality is unstable and frequent fluctuations, resulting in too much particulate matter entering the filter element, resulting in a shortened cycle; Second, the pretreatment operation effect is poor, the pretreatment dosing flocculants, scale inhibitors, etc. Incompatible with each other or mismatch with the water source, the formed viscous 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. The outer layer plays a role of interception, and the filter pore size of a good filter element is gradually reduced from the outside to the inside, and the dirt holding capacity becomes larger. The long time used can ensure the qualified water quality. So, what can be done to reduce the frequency of replacement of the security filter element? The main methods are divided into the following aspects: 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 the scale inhibitor suitable for the water source, and adjust each pretreatment The treatment equipment reaches a good operating condition, and strictly follows the requirements of the operating regulations to ensure that the pretreatment effluent quality is qualified; ③The use of quality-guaranteed brand filter elements can not only extend the life of the filter element, but also ensure the effluent quality of the security filter. For example, Lvyuan security filter element. This kind of filter element is unmatched in terms of retaining water dirt, lower pressure loss, and longer service life than most similar filter elements.
