Which specification of quartz sand is used for swimming pool filter sand tank

Quartz sand has many uses, and it is mainly filled in the sand tank in the form of filter material in swimming pool water treatment. The swimming pool sand tank is the most important component of the filtration system, which plays a role in purifying water quality. The quality of filtered water also mainly depends on the function of quartz sand, which can trap and absorb impurities in the water, so that the discharged water is clean and clear.

However, swimming pools have different specifications, and sand tanks also have different specifications. The specifications and quantities of quartz sand that need to be filled are naturally also different. So which specification of quartz sand is more suitable? Let's find out below.

Quartz sand is an essential filter material for swimming pool filtration, and it is also the filter material for its main function. The filter is to use special quartz sand to eliminate the tiny dirt in the pool. First, the swimming pool water is pumped into the sand tank by the water pump.

Microscopic dirt in the water is captured and filtered out by the sand bed. The filtered clean water passes through the control switch at the bottom of the filter and returns to the swimming pool through the pipeline. This is a set of continuous and automatic circulation process, which makes the swimming pool water get purified.

The quartz sand is closely arranged in the sand tank, and the pool water is from top to bottom. The solid suspended matter in the water is adsorbed and trapped by the quartz sand. At the same time, these trapped impurities overlap and bridge to form a thin film to continue to filter the water. Impurities. If the quartz sand is to be closely arranged, the specification should be smaller. This is so that it can be arranged tightly.

Has a good alignment effect. Generally, the most commonly used quartz sand specifications are 1-2mm, 2-4mm, and 4-8mm. It can be selected according to the size of the sand tank, or it can be mixed and arranged in layers, and the effect is also very good.

Generally, larger sand tanks will be mixed. The bottom layer will be filled with larger-grained quartz sand, while the upper layer will be filled with finer-grained quartz sand. In this way, they cooperate with each other to achieve the best filtering effect. If it is a small sand cylinder, it is enough to adapt to the smaller size of quartz sand.

In addition, the quartz sand does not need to fill the entire sand cylinder, only about 2/3 of the amount can be filled. Note that the sand tank should be backwashed every six months or a year to clean the sand tank and quartz sand and restore the filtering function.
