In industrial production, metal filter elements are often used to filter industrial water. When using filter elements, it is necessary to understand the correct installation method of filter elements and the replacement method of metal filter elements.
How to replace the metal filter?
1. Close the power of the filter element system and the front and rear valves of the metal filter element.
2. Open the sewage outlet and drain the water in the metal filter element.
3. Open the upper cover and pull out the metal filter element.
4. Flush the inner cylinder wall of the metal filter element.
5. Install the metal filter element and seal the upper head.
6. Seal the drain outlet of the metal filter element, and open the front and rear valves of the metal filter element.
When do metal filters need to be replaced?
| 1 | When the quality of the influent water is unstable and frequently shakes, the particulate matter entering the metal filter element is too much, and the formation cycle is shortened. |
| 2 | When 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, and the formed sticky substances adhere to the surface of the metal filter element, resulting in a reduction of the effective filtration area of the metal filter element. Form metal filter element replacement frequently. |
| 3 | The quality of the metal filter element is not good. The inner and outer pore diameters of the poor-quality metal filter element are basically the same. In fact, as long as the outer layer has a blocking effect, the filtration pore size of a good metal filter element is gradually reduced from the outside to the inside, and the amount of pollutants is large. A long time can also ensure that the quality of the effluent is qualified. |
