Self-cleaning filters are now used in water treatment in various industries and have become an indispensable equipment for enterprises. However, it is impossible for any equipment to be free of problems all the time, and self-cleaning filters are no exception. So what are the factors that cause problems in the operation of self-cleaning filters? Self-cleaning filters use high-strength stainless steel mesh to handle a large amount of dirt. The service life of self-cleaning filters is relatively long, the cleaning power is relatively high, and it also has the function of saving water.
The main reasons for the abnormal operation of self-cleaning filters are:
1. The selection of filter media for self-cleaning filters. The filter media uses anthracite and quartz sand. The selection of such graded filter media increases the operating resistance due to the small particle size. In the case of incomplete backwashing, it is very easy to produce filter media compaction.
2. Backwash intensity of self-cleaning filter. Backwash intensity = backwash water volume (L)/filtration area (m2) × flushing time (s). The backwash intensity requirement should not exceed the flushing intensity allowed by the upper filter material (anthracite), and it should also ensure that the base quartz sand has enough backwash time to flush it clean. If it is too large, it is easy to leak material, and if it is too small, the backwashing is incomplete.
3. Self-cleaning filter head. Because the plastic material selected for the filter head is not strong enough, it is damaged, resulting in the loss of filter material.
4. The filter material is hardened and leaks material seriously, and the filtering effect is poor. The filter material must be replaced every 6 months to 1 year, and the water quality of the effluent fluctuates greatly, and the oil removal effect is not good. The electric self-cleaning filter still uses uninterrupted water supply during the self-cleaning process. While ensuring the quality of the effluent, it also improves the working efficiency. In this way, the electric self-cleaning filter can not only reduce the pollution of sewage to the river, but also convert sewage into recycled water that can be used by humans, which is also a concrete manifestation of my country's water conservation action.
The water treatment function of the self-cleaning filter is very strong and it is a widely used device. The device is favored by users because of its simple operation and super strong decontamination function. If you encounter abnormal operation of the device, you can learn the reason through this article.
