Background

The circulating purifying system for swimming pool is that the water in the swimming pool overflows from the pool at a certain flow rate and flow speed, and after being filtered and purified, the water is disinfected and sterilized and then returned to the pool for reuse. The filtering stage is a key process of the pool water purification treatment, and is a link capable of generating energy-saving and emission-reducing effects in a water quality treatment system of the swimming pool.

Colloidal substances in water are main factors for forming turbidity, can be in a stable state for a long time and are difficult to remove by gravity; and the colloid can not be oxidized by the disinfectant and can only be removed by filtration. Therefore, the use of a filter having a higher filtration accuracy in a water treatment system for a swimming pool is an effective measure for achieving a lower turbidity of the pool water. Therefore, the filtration is the most critical process in the water quality treatment system of the swimming pool.

The diatomite is a porous biological silicalite formed by remains of unicellular aquatic plant diatoms through long-term diagenetic action, and is processed into white diatomite through a physical and chemical method. Has larger specific surface area and porosity as high as 90 to 92 percent. The main component of which is SiO₂Greater than 90% and containing a small amount of Al₂O₃The particle size of the particles is 0.001-0.5 mm, and the particles are nontoxic, tasteless and good in chemical stability. The high-precision porosity reduces the filtration resistance and filters fine colloids.

After the filter is used for a period of time, the filter screen needs to be backwashed, so that filter material particles adsorbing impurities can be washed, and in order to realize the recycling of the filter material, a filter material recycling device is necessary.
