Factory Supplier Top Mount Stainless Steel Pool Sand Filter

Working principle of stainless steel swimming pool sand filter:

The pool sand filter uses a special sand filter to eliminate the tiny dirt in the pool. Sand, as a medium for removing dirt, is filled in the cavity inside the filter. When the control knob is set to the "FILTER" position, the pool water containing suspended dirt particles is pressed into the filter pipeline by the pump, and then guided by the control switch to the outlet of the filter. The pool water passes through a filter, and tiny dirt is captured and filtered by the sand bed. The filtered clean water is returned to the swimming pool through the control switch at the bottom of the pool sand filter and then through the pipeline. This whole set of procedures is continuous and automatic, and provides a complete circulation process for the pool sand filter and piping system of the swimming pool. After a period of use, the accumulated dirt hinders the water flow and weakens it. At this time, the pool sand filter should be cleaned. Turn the control switch to the "BACKWASH" position, then the water will flow in the opposite direction. The water will directly reach the bottom of the chamber of the FILTER crying device, then it will be flushed up through the sand layer, and the previously collected dirt and residues will be flushed up and discharged from the sewage outlet. After each backwash, turn the control switch to the "RINSE" position, turn on the water pump for 0.5 to 1 minute, and then turn it off to the "filter" position to restart the normal filtration.

The Advantages of Stainless Steel Pool Sand Filter:

1） The stainless steel pool sand filter is never broken, and its effective service life is at least 50 years. The life of glass fiber sand tank is 5 years.

2） Stainless steel pool sand filters are very environmentally friendly and will not cause secondary pollution to water quality. The glass fiber sand tank will slowly dissolve, causing secondary pollution to water quality, while the glass fiber dissolved in water will cause serious damage to human body, which is a strong irritant and a powerful carcinogen. Glass fiber sand tanks have been banned in developed countries;

3）Stainless steel pool sand filter are very corrosion resistant, and they are the necessary filtering equipment for mariculture and aquarium, while glass fiber sand tanks cannot be used for this purpose;

4） The effective temperature resistance of stainless steel pool sand filter can exceed 300 degrees, while that of glass fiber sand tank is only 43 degrees; Therefore, it is the first choice of filtration equipment for hot springs;

5）Stainless steel pool sand filter has smooth surface and excellent texture, which can effectively improve the grade of swimming pool equipment;

6) Stainless steel pool sand filter can be customized with any flow rate.
