Quartz sand Basic principle of filter material filtration: quartz sand filter material has filtering effect, just as water penetrates into the ground according to sand and stone, it blocks suspended solids in water. The key is these weak suspended solids.

The general quartz sand filter material is generally suitable for wastewater treatment. It has no problem after three to five years of application. It is only necessary to avoid the loss of quartz sand, and environmental pollution is not important. Due to wastewater treatment, sludge can itch or anaerobic respiration, and pollutants in wastewater are dissolved. If it is used for pure water treatment, it is mainly used for fine quartz sand filter material.

In filters, it usually needs to be replaced for 2 to 3 years. Generally, after the pollutants are encapsulated by quartz sand, they can no longer have good filtering effect, and only need to be replaced.

For customers of quartz sand filter material, special attention should be paid to filling or replacing the quartz sand filter material immediately. The key factor is that the quartz sand filter material will be lost in the whole process of application, and will also be polluted by the environment, reducing its own actual filtering effect. Therefore, in order to better maintain the actual filtering effect of quartz sand filter material, the quartz sand filter material is replaced and added immediately because the quartz sand filter material is improved.

The basic of filtering the actual effect.

When replacing the quartz sand filter material, attention should be paid to: generally, the quartz sand filter material is not easy to have any problems in sewage treatment within three to five years. What we should do is to avoid the damage of the quartz sand filter material.

It is not important that quartz sand is polluted by waste water environment. Sludge can itch or anaerobic respiration, dissolving pollutants in water. But for the fine quartz sand filter material, if the pure water is treated, it can be used for 2-3 years. Once the environment is polluted, it can be replaced immediately, otherwise the actual filtering effect will be seriously affected.

Snow white sand It is a kind of commodity for mining, production and processing. Natural quartz sand is widely used in people's daily life, which shows the necessity of natural quartz sand in the market. The precious network resources that can not be regenerated by natural quartz sand are not inexhaustible network resources. The actual effect of natural quartz sand filtration material in sewage treatment is excellent, and the market share will become smaller and smaller. Quartz sand is also a major mineral raw material for industrial production, non chemical dangerous goods, which is widely used in laminated glass, casting, porcelain and refractory insulation materials. Ferrosilicon smelting plant, melting agent for metallurgical industry, metallurgical industry, engineering construction, chemical plant, plastic, rubber, wear-resistant materials and other fields.
