Quartz sand filter material is made of natural quartz ore, which is crushed, washed, dried and screened twice. No impurities, no edges, high density, high mechanical strength, strong dirt interception ability and long service life. It is an ideal material for chemical water treatment. Refined quartz sand filter material, ordinary quartz sand filter material, etc.
Made of natural quartz ore, processed through crushing, screening, washing and other processes.
The appearance is polygonal, spherical, pure white, and has the characteristics of high mechanical strength, strong dirt interception ability, and good acid resistance. Quartz sand filter material
At present, natural river sand and sea sand are used as filter materials in some areas. Although the cost is low, the service life is short, the mechanical strength is poor, and it is easy to break. The service life of quartz sand is three times longer than that of natural sand. Moreover, the water quality after filtration is stable. From the perspective of economic benefits, relatively speaking, this quartz sand is much cheaper than river sand and sea sand. Domestic quartz sand filter media has reached the world's leading level.
What is quartz sand
Quartz sand packaging and storage:
Among all influencing factors, matrix factors and values determine the incoming water quality. The control of these factors mainly relies on daily monitoring and strict enforcement of relevant regulations and laws. For general urban sewage, most of these factors will not have much impact, and each parameter can basically be maintained within an appropriate range. Temperature changes are related to climate. For a 10,000-ton urban sewage treatment plant, especially when using the activated sludge process, temperature control is difficult to implement, and it is not very feasible economically or engineeringly. Therefore, the processing requirements of different temperature changes are generally met through appropriate selection of design parameters to achieve the processing goals. Therefore, the main goal of process control falls on the activated sludge itself and the environmental factors that can be changed through control means. The main task of control is to take appropriate measures to overcome the influence of external factors on the activated sludge system so that it can Function continuously and stably.
Quartz sand filter material is made of natural quartz ore as raw material, which is processed by crushing, washing and fine screening. It is currently the most widely used and largest water purification material in the water treatment industry. It has no impurities and is pressure-resistant and durable. Grinding machine has high mechanical strength, stable chemical properties, strong interception ability, high efficiency and long service life. It is suitable for single-layer and double-layer filter pools, filters and ion exchangers. All indicators meet the (C/) standard. . We process refined quartz sand, pure white quartz sand, acid treatment agent, and ordinary quartz sand to meet the needs of different users. Commonly used specifications: .. ..
Ordinary quartz sand filter material plays a filtration role, just like water penetrates into the ground through sand and gravel, blocking suspended objects in the water, mainly for those fine suspended objects. Quartz sand technology has reached the leading domestic level. Scope of application of quartz sand filter material: The ordinary quartz sand produced by our company is generally a water treatment filter material made of natural quartz ore, which is crushed, washed, dried and screened twice..., refractory degree ℃, appearance part Large particles with yellow skin cysts on the surface. Quartz sand filter material has the characteristics of: no impurities, no correction, high density, high mechanical strength, long service life of dirt-carrying capacity, and is an ideal material for chemical water treatment. Quartz sand is an important industrial mineral raw material and a non-chemical dangerous product. It is widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. Technical requirements for quartz sand filter material: The sum of the crushing rate and wear rate of quartz sand filter material should not be greater than (percentage based on mass, the same below). , The density of quartz sand filter material should not be less than ./c, unless there are special requirements for density during use. , The quartz sand filter material should not contain visible soil, mica and organic impurities, and the water leachate of the filter material should not contain toxic substances. The mud content should not be greater than, and the content of light substances with density less than /c should not be greater than. , The ignition loss of quartz sand filter material should not be greater than. , The hydrochloric acid solubility rate of quartz sand filter material should not be greater than. Glass sand... is made from selected high-quality ores for complex processing. The particle size range is suitable for use and can be produced according to user requirements. The appearance is white or crystalline.

Characteristics of quartz sand filter material:
High hardness, good corrosion resistance, high density, high mechanical strength, long service life of dirt-carrying capacity, it is an ideal material for chemical water treatment quartz sand filter The material plays a filtration role, just like water seeping into the ground through sand and gravel, blocking those suspended objects in the water, mainly targeting those fine suspended objects.
Quartz sand filter materials are mainly divided into the following categories:
Ordinary quartz sand filter materials: mainly used in sewage treatment, can be used for years, as long as the loss of quartz sand is prevented, it does not matter if it is contaminated, because In sewage treatment, sludge can undergo aerobic or anaerobic respiration to degrade pollutants in sewage.
Quartz sand filter material: used in pure water treatment. In sand filters, it can generally be used for years. Usually after it is contaminated, the pollutants wrap around the quartz sand and it can no longer play a good filtering role. Can be replaced.
Quality standards: Quartz sand filter media has passed quality system certification.
Technical requirements for quartz sand filter material:
The sum of the crushing rate and wear rate of quartz sand filter material should not be greater than (percentage based on mass, the same below).
The density of quartz sand filter material should not be less than ./c, unless there are special requirements for density during use.
