Careful selection of filter material for swimming pool sand tank filter

The sand of the swimming pool sand tank filter is a kind of hard and wear-resistant quartz sand, which is mainly used in swimming pools for filtration, and quartz sand is the main filter material of the sand tank, so the quality of the quartz sand directly determines the quality of the sand tank. filter effect. The shape of the quartz sand used for sand tank filtration is that the regular hexahedron of the swimming pool filter sand tank has eight corners. When the sand tank is stacked, there will be gaps between the corners of each quartz sand and the corners. These gaps allow water to pass through smoothly, but impurities larger than the gaps cannot pass through, so that it can play a purifying role.

The size of the gap determines the filtration accuracy of the sand tank. When the gap is small, the filtration accuracy is higher, but if the gap is too small, the water output of the entire sand layer will be reduced, thereby affecting the water output of the sand tank. Therefore, the gap between the quartz sand determines the filtering effect, and the size of the quartz sand and the integrity of the quartz sand directly determine the size of the gap in the quartz sand. Therefore, it can be known that the size of the British sand and the integrity of the quartz sand are the most important factors for the filtration of the sand tank.

The advantages of the stainless steel sand tank: 1. The stainless steel sand tank is not bad forever, and the effective service life is at least 50 years. The life of the glass fiber sand tank is 5 years; 2. The stainless steel sand tank is very environmentally friendly and will not cause secondary pollution to the water quality. The glass fiber sand tank will slowly dissolve, causing secondary pollution to the water quality, and the glass fiber dissolved in water will cause serious damage to the human body, and is a strong irritant and a strong carcinogen.

The use of glass fiber sand tanks has been banned in developed countries; 3. Stainless steel sand tanks are very corrosion-resistant and are the necessary filter equipment for mariculture and aquariums, while glass fiber sand tanks cannot be used for this purpose; 4. The effectiveness of stainless steel sand tanks The temperature resistance can exceed 300 degrees, while the temperature resistance of the glass fiber sand tank is only 43 degrees; therefore, it is the preferred filter equipment for hot springs; 5. The surface of the stainless steel filter sand tank is smooth and the texture is excellent, which can effectively improve the grade of swimming pool equipment; 6. Stainless steel sand tank The cylinder can be customized for any flow rate equipment. The above is the detailed introduction of "Swimming pool sand tank filter material selection needs to be cautious".
