Maintenance method of Pool Sand Filters
Today's sand filters are basically made of very durable materials. The inner filter of FRP sand filtration tank is made of FRP reinforced polymer resin by blow molding, and its shell is reinforced by FRP winding. It has fine texture, strong structure, wear resistance and durability, and its service life is generally more than 10 years.
Then how to maintenance the sand filters, please see below ways:
1. The sand filter of the swimming pool should be used normally, which means the circulation system should be used normally. Some swimming pools don't pay much attention to this. The circulation system is idle there as a decoration. It won't be opened once every six months or a year. This is not only not responsible for water quality, but also detrimental to the circulation system. Too long idle can cause problems with individual components. It's not as good as if the house is idle for too long, it's easy to collapse, and the circulation system is idle for too long, it's easy to malfunction.
2. Regular inspection, that is, regular inspection of whether the circulation system can be used normally, whether there is water leakage or other problems, whether there is aging and failure of components, if there is, it should be improved.
3. Clean regularly. The filter system has been used for a long time. There will be a lot of impurities, grease and other dirt accumulated in the sand tank and pipeline. The accumulation of these things will affect the filtering effect of the system and even make the water quality worse. Therefore, it is necessary to clean it half a year or once a year. These stubborn stains should be cleaned with professional detergent and professional methods. The sand tank uses the sand tank cleaning agent, fills the sand tank with water, pours the cleaning agent to soak for about 24 hours, and carries on the back washing. Clean the pipeline with pipeline cleaner.
4. Replace slilicon sand regularly. Silicon sand filtration is an important step in water purification. Silicon sand is very important. It has a long service life and can be used for several years under normal maintenance. However, the silicon sand needs to be replaced once in about 3 years. Due to long-term filtration, water infiltration and so on, the adsorption capacity of sand to dust will be weakened, and the filtration effect will also be reduced, so slilicon sand should be replaced once in almost three years.
