Comparison of two traditional water treatment equipment for swimming pools

There are more and more swimming pools being built, and the water quality of the swimming pool is an important factor in the length of running the swimming pool. There are two traditional types of filtration equipment for swimming pool water treatment equipment on the market. The following are detailed introductions: Swimming pool filter sand tank: Generally, a certain scale of quartz sand is placed in the swimming pool filter sand tank. The size and specification of quartz sand are different within a certain range. In the sand tank, the quartz sand is arranged from top to bottom, from small to large. During normal filtration, water enters from the upper layer of sand and comes out from the lower layer. When water flows through the filter layer from above, part of the solid suspended matter in the water enters the tiny holes formed by the upper filter material and is trapped by the surface layer of the filter material due to adsorption and mechanical retention. At the same time, the suspended matter between these trapped Overlapping and bridging occurs again, as if a thin film is formed on the surface of the filter layer, which continues to filter the suspended matter in the water, which is the so-called membrane filtration of the surface layer of the filter material.

This filtering effect is not only on the surface of the filter layer, but also has this interception effect when water enters the middle filter layer. In order to distinguish it from the filtration of the surface layer, this effect is called osmotic filtration. In addition, because the sand particles are closely arranged with each other, when the suspended particles in the water flow through the tortuous channels in the sand layer, there will be more opportunities and time to collide and contact with the surface of the filter material. The suspended solids in the sand layer bond with the flocs on the particle surface of the sand layer to form a contact coagulation process. To sum up, the filtration of the sand tank is to further purify the water through the process of membrane filtration, osmosis filtration and contact filtration.

The principle of buried circulation filtration: The buried circulation filtration system is an intelligent circulation filtration system integrating pump room, filtration, dosing and disinfection, etc., which changes the traditional sand tank filtration method. It is suitable for the standards of public swimming pools in many countries such as China and Australia. It is a filtration system specially used for large public swimming pools and competition swimming pools with a volume of more than 500 cubic meters. The principle of wall-mounted and embedded is the same as that of buried, but the installation method is different.

To sum up, swimming pool operators can choose swimming pool filtration equipment according to their own economic strength to ensure the safety and hygiene of swimming pool water. Poolking is the best swimming pool equipment manufacturer and supplier in China. Poolking exists to provide the highest quality swimming pool equipment while offering competitive pricing..

Bigger is not always better when it comes to pool pumps. A pool pump that is too large can hinder filtration and can even damage a pool’s filter and/or heater. It is therefore very important to know the size of a pool before purchasing a pool pump. If there is additional equipment (such as water features) installed into the pool, it will have to be taken it into account when deciding what size pump is going to be purchased. The more equipment is installed into a pool, the more powerful the pump needs to be.
It is important to consult with a pool equipment expert, such as Poolking's Pumps, before buying a pool pump. The team at Poolking will be able to give our customers professional advice regarding the size of the pump they will need to purchase.
After about 5~10days ,or when the reading of the pressure gauge on the pump side of the filter has increased by about 0.2bars since the last backwash , backwash the filter as follows:
1. Stop the pump
2.Close the valves on the suction and return lines.
3.Open the cover of the pump and empty the filter gasket .
4.Refit the cover
5.Open the valve to the drain outlet
6.Turn the lever to BACKWASH
7. Open the valves to the suction and return lines.
8.Start the pump .Rinse the filter for about 1 to 2 minutes until the water in the sight glass is clear .
NOTE : Any electric heater must be off .
