How to prolong the service life of stainless steel filter element

Add Date:2020-12-30 General view:57

The reasons for shortening the cycle of stainless steel filter element are as follows:

 

1. The raw water quality of stainless steel filter element is unstable and fluctuates frequently, which leads to too much particulate matter entering the filter element and shortens the cycle;

 

2. The operation effect of stainless steel filter element pretreatment is poor. The flocculant and scale inhibitor are incompatible with each other or do not match with the water source. The viscous substance formed adheres to the surface of the filter element, resulting in the reduction of the effective filtering area of the filter element and frequent replacement of the filter element;

 

3. The quality of stainless steel filter element is not good. The inner and outer pore diameters of poor quality filter elements are basically the same. In fact, only the outer layer plays the role of interception. The filtration pore diameter of good filter elements is gradually reduced from the outside to the inside. The inner layer filtration accuracy is 5 ± 0.5 μ m, the pollution capacity is larger, and it takes a long time to ensure that the water quality is qualified.

 

After the above finishing, the following measures can be taken to extend the service life of stainless steel filter element:

 

1. Generally, the water source is fixed and should not be changed easily;

 

2. Improve the operation effect of pretreatment, optimize the dosage of flocculant and coagulant aid, select the scale inhibitor suitable for the water source, adjust the pretreatment equipment to achieve the best operation state, strictly comply with the requirements of the operating procedures, and ensure the quality of the pretreated effluent;

 

3. The stainless steel filter element adopts the brand filter element with guaranteed quality, which can not only prolong the service life of the filter element, but also ensure the effluent quality of the filter.

 

In order to prolong the service life of stainless steel filter element, the most important thing is to pay attention to the selection of its quality and the methods in the process of use.
