Lifelt security high-throughput filter adopts large flow pleated filter element, which is mostly used for security filtration, cleaning filtration, backwash filtration, condensate filtration, etc. in water treatment with large flow. Relying on many years of filtering technology, the company has continuously improved the structure and process, and now produces this kind of filter, which has a compact structure, advanced technology, stable and reliable quality, and has been widely used in many fields. The equipment uses imported large flow pleated filter elements such as 3M, Parker, Lifelt, etc., which can obtain a larger effective filtration area. Ensures stable filtration in a compact space.

Conditions for replacing the security filter element:

1. The quality of the filter element itself is not good. The inner and outer pore diameters of poor quality filter elements are basically reduced step by step from the outside to the inside. The filtration accuracy of the innermost layer is 5+0.5um, and the dirt holding capacity can also become larger. Use The time can also ensure that the water quality of the effluent can meet the regulations.

2. The operation effect during pretreatment is relatively poor. When the flocculant and scale inhibitor added during pretreatment are incompatible with each other or do not match the water source, sticky substances will be formed and adsorbed on the surface of the filter element. It will reduce the effective area of the filter element and cause the blockage of the filter element;

3. The water quality of the source water is already unstable, and it will fluctuate frequently, resulting in too much particulate matter entering the filter element, which will shorten the cycle;

How to replace the filter element of the security filter:

1. Turn off the reverse osmosis device system;

2. To remove the pressure, press the button of the pressure relief valve on the equipment until the indication on the pressure gauge is zero;

3. Use a professional wrench to rotate the filter bottle to open;

4. Pull out the old filter element and replace it with a new one;

5. Use a professional wrench to rotate and tighten the filter bottle of the filter.
