Technical characteristics of quartz sand filtersThe quartz sand filter material layer is thicker, the filter tank is deeper, and the civil construction cost is higher. The filtration efficiency is high, the filtration effect is better, there is no need to stop the backwashing, and the operating cost is low. The head loss is high, and it is generally necessary to set up a secondary lifting pump room, which increases the operating cost.

The activated sand filter can flexibly increase or decrease the number of filters according to the change of water volume, and is mainly suitable for small-scale sewage treatment plants.

The activated sand filter is a continuous filtration equipment integrating flocculation, clarification and filtration, which is widely used in the fields of drinking water, industrial water, advanced sewage treatment and reclaimed water reuse treatment. The system adopts the principle of upflow flow bed filtration and a single homogeneous filter material, the filtration and sand washing are carried out at the same time, and can run continuously and automatically for 24 hours, and the ingenious sand lifting and sand washing structure replaces the traditional high-power backwashing system, and the energy consumption is extremely low.

The common specifications and densities of quartz sand are as follows:

6-8mm quartz sand particle size, main data, specific gravity, bulk density;

4-6mm quartz sand particle size, main data, specific gravity, bulk density;

2-4mm quartz sand particle size, main data, specific gravity, bulk density;

1-2mm quartz sand particle size, main data, specific gravity, bulk density;

Quartz sand particle size, main data, specific gravity, bulk density;

40-70 mesh quartz sand particle size main data specific gravity, bulk density;

70-100 mesh quartz sand particle size main data specific gravity, bulk density;

Quartz powder particle size, main data, specific gravity, bulk density;

The common ones are the densities of two types of quartz sand:

is true density = equivalent to the true density under the complete crystal structure of SiO2.

Bulk density = fixed number of sand, piled up, with a gap in the middle. Divide the weight of this pile of sand by the volume of the pile.

Whether it is or if it is a density, then it is a ton of cubic meters, or kg l (cubic decimeters), the unit of the building is also kg l, but it should be the density of the quartz sand itself (that is, the density of a single quartz sand), and the density of the quartz sand should usually be the bulk density, that is, the pile (such as the weight of 1 cubic meter or 1 liter of quartz sand).

Common specifications of quartz sand: common specifications of quartz sand are: mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh.

Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. It can be transported by car, train and water. Industrial production is generally 50kg or 25kg packaging and export ton bag packaging.

Common specifications: 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm(mm is in millimeters).

Quartz sand filter material, compressive and wear-resistant, high mechanical strength, stable chemical properties, strong dirt interception ability, high efficiency, long service life, suitable for single-layer and double-layer filter pools, filters and ion exchangers, all indicators have reached (CJ T43-2009). Refined quartz sand, pure white quartz sand, acid treatment agent, ordinary quartz sand are processed to meet the needs of different users. Common Specifications:

1-2mm 2-4mm 4-8mm 8-16mm 16-32mm。

The number of meshes, which is the number of holes, is the number of holes per square inch. The larger the mesh, the smaller the aperture. In general, the mesh aperture (number of microns) = 15000.

For example, the pore size of a 400-mesh screen is about 38 microns; The pore size of the 500 mesh screen is about 30 microns. Due to the problem of porosity, that is, because of the different thickness of the silk used in weaving the net, the standards of different countries are not the same, there are currently three kinds of American standards, British standards and Japanese standards, of which the United Kingdom and the United States are similar, and the difference between Japan is large. Our country uses the American standard, which can be calculated using the formula given above.

Therefore, if you want to know how much purpose quartz sand is, the simple way is to use a sieve to sift it, and how many mesh sieves can be completely passed, and how many purposes of your quartz sand is. That's what the instrument does.
