The quartz sand in pure water equipment has always played a bridging role, and there is also a particle size issue with this material that troubles us, which is not knowing how to choose, afraid that selecting an unsuitable one will affect the equipment.

Quartz sand, as one of the indispensable filtering materials in pure water equipment, can remove some pathogens, bacteria, and organic chemical substances in water, making it more hygienic and safe. The quartz sand in pure water equipment uses plastic film filtration, infiltration filtration, and touch filtration functions to remove particle residues, suspended solids, colloidal solutions, etc. from the water. Can reasonably reduce the turbidity of the source water, making the water clearer and clearer. Quartz sand in pure water equipment is suitable for industrial water filtration, domestic water filtration, and other sewage purification solutions. More suitable for the early solution and circulating water treatment of tap water in the production and manufacturing of dry crude oil, chemical plants, mining, metallurgical industry, thermal power plants, papermaking industry, printing and dyeing plants, leather factories, food and other industries.

Quartz sand selection method: The sum of the bulk density and wear of the quartz sand filter material cannot compete for 1.5% (percentage by quality, the same). The relative density of quartz sand filter material shall not be less than 2.55g/cm3. Except for those with unique requirements for relative density in applications. The quartz sand filter material should have no visible soil, biotite, or organic chemical residues. The water extract of the filter material should be free of toxic substances, and the powder content should not exceed 1%. The composition of light chemical substances with a relative density below 3g/cm3 shall not exceed 0.2%. The burning reduction of quartz sand filter material should not exceed 0.7%. The sulfuric acid solubility of quartz sand filter material shall not exceed 3.5%.

The quality of a company's products can actually be detected by checking, and the reliable output rate of the company's machinery and equipment are very strict and attractive, and the machinery and equipment will give people a sense of hierarchy. Another thing is to check if the sound card frame of the purified water equipment is level during welding. The pipeline connection regulations for machinery and equipment must be aesthetically pleasing, horizontal and flat, and must be clearly marked to enable customers to understand. Moreover, all pipelines should be connected using UPVC or standard 304 stainless steel plates to ensure that the machinery and equipment are not easily affected by pipeline problems in the middle and later stages of normal application.

The particle size range of quartz sand filter material for single-sided or two-layer biological filters is generally 0.5-1.2 millimeters. The particle size range of quartz sand filter material in a three-layer filtration material biofilter is generally 0.5-0.8 millimeters. In various particle size categories of quartz sand filtration materials, the particle size below the specific low limit shall not exceed 3%, and the particle size exceeding the specific limit shall not exceed 2%. The reasonable particle size and non-uniformity coefficient of quartz sand filter material shall be determined by the application enterprise.
