How to Maintain The Wholesale Swimming Pool Sand Filters Correctly?

The wholesale swimming pool sand filter is the main equipment of the circulation system, which is used to filter the pool water and purify the water. So, what is the working principle of the sand tank? We all know that quartz sand is filled in the swimming pool sand filter. Why do you want to fill the sand? We all know that water can penetrate into the surface to become clear groundwater; when we do experiments, we can filter the turbid water into the deep sediment of the sediment to filter out clean water. Yes, the pool filter is also based on the principle of deep filtration. When the pool water passes through the swimming pool filter, the impurities in the water will be trapped by the sand, and the water will flow back to the pool through the pipeline.

 

The stone filled in the above ground pool filter is quartz sand, which is the special filter sand to eliminate the tiny dirt in the pool water. The sand filter does not have to fill the entire sand tank, and it is probably filled in 2/3 position. When the control knob hits the "FILTER" position, the pool water containing suspended dirt particles is pumped into the filter line by the pump and then guided by the control switch to the water outlet of the filter. The pool water is filtered through the sand filter, and tiny dirt is intercepted by the sand bed. The filtered water is returned to the pool from the bottom of the filter via the control switch and then from the pipe. This complete set of procedures is continuous and automatic, and together with the pool sand filter and the pipeline constitute a complete circulation system.

The circulatory system is often used, and it takes a long time. The surface of the sand filter covers a large amount of impurities that are filtered and retained. The more these impurities accumulate, the less the filtration effect of the sand filter is weakened, and the filtration effect of the entire circulation system is weakened. Therefore, after a certain period of time, the filter needs to be cleaned, which is what we usually call backwashing. Backwashing is the most important aspect of the maintenance of a swimming pool sand filter. First, turn the control switch to the "BACKWASH" position, so that the water flow will flow in the opposite direction. The water flow will go up from the bottom of the sand filter and backflush through the sand layer. The accumulated dirt will be intercepted and the residue will be washed away and discharged from the sewage outlet. Clean the inside of the sand filter. After backwashing, turn the control switch to the "RINSE" position, turn the pump on for 0.5 to 1 minute, then turn it off, then hit the "FILTER" position and resume normal filtration.

The above is the working principle of the sand filter. Maybe you want to know how long the sand tank can be used. How can it be used to maintain the longest service life? You don't have to worry about this. Because the current sand cylinders are basically made of very durable materials. The inner wall of the FRP filter sand tank is formed by blow molding using FRP-reinforced polymer resin, and the outer casing is reinforced with FRP fiber winding. The art is fine and the structure is solid. Durable and durable, its service life is generally more than 10 years. Let's take a look at the maintenance method of the pool filter.

The structure of the inground pool filter is tight, the quality is too strong, and it can be used for a long time. It is not a problem for more than ten years, and it can even be used for a longer time.

1. Sand filter to the normal use of the swimming pool, which is the circulatory system to normal use. Some swimming pools don't pay much attention to this, and the circulatory system is idle as a decoration, and it will not be opened once every year for half a year. This is not only responsible for the water quality, but also for the circulatory system. If it is idle for too long, it will cause problems for the components. For example, if a house is left idle for too long, it will easily collapse, and if the circulation system is idle for too long, it is prone to failure.

2. Regular inspection, that is regular inspection of whether the circulatory system can be used normally, whether there is water leakage or other problems, whether the components are aging or faulty, if any, should be improved.

3.Clean regularly. The filtration system has been used for a long time, and many impurities, grease and other dirt will accumulate in the sand filter and the pipeline. These things accumulate more and block inside, which will affect the system filtration effect and even make the water quality worse. Therefore, it is necessary to carry out cleaning once every six months or one year. These stubborn stains should be cleaned with professional detergents and professional methods. The swimming pool filter system uses the sand tank cleaning agent, and the sand tank is filled with water, and poured into the sand tank cleaning agent for about 24 hours to perform backwashing. Use a pipe cleaner to clean the pipe.

4. Regularly replace quartz sand. Quartz sand filtration is the most important step in water purification. Quartz sand is very important. These sands have a long service life and can be used for several years under normal maintenance conditions. However, it is generally necessary to replace the quartz sand once in about 3 years. Due to long-term filtration, water infiltration, etc., the dust adsorption capacity of the sand is weakened, and the filtration effect is also reduced. Therefore, the quartz sand should be replaced once in about three years.
