What are the characteristics of garnet filter media

Garnet filter material is processed from natural silicate mineral garnet with stable chemical properties, which has high melting point, specific gravity, high hardness, strong acid and wear resistance, good chemical stability, and is a new type of wear-resistant water purification material. Garnet filter material has the characteristics of specific gravity, high hardness, good toughness, wear resistance, acid and alkali resistance, and moderate porosity, and is widely used as high-density filter material (heavy medium filter material) in the field of sewage treatment. Garnet has a strong competitiveness in the filter media used as a water filter for the gravel layer, showing a broad prospect, because it has some points that the filter media does not have, such as the filter media of garnet as a water filter is free of organic matter, no broken or ground minerals, and also does not contain acid-soluble components and other fine-grained materials.

Garnet filter material has the characteristics of specific gravity, high hardness, good toughness, wear resistance, acid and alkali resistance, and moderate porosity, and is widely used as high-density filter material (heavy medium filter material) in the field of sewage treatment. Now the better domestic garnet mining is Rizhao City.

The filter material is an island-like structure of aluminum (calcium) silicate, also known as jade sand, natural corundum, etc., with strong hardness and good acid and alkali resistance, garnet can be used as a water filter medium, is a new type of filter material with high efficiency and long life, and is widely used as a high-density filter material in the field of sewage treatment.

The proportion of garnet filter material is large, and there will be almost no garnet filter material overflow when the sewage treatment tank or water overflows, which improves the efficiency of water pollution treatment. The shape of garnet filter media particles is commonly diamond-shaped 12-sided or four-corner 38-sided crystals, and the polyhedral characteristics can produce more suitable voids between the particles of ordinary shape than other filter materials, which can play a better filtration effect. Rizhao Garnet Mining is a company specializing in garnet products.

Garnet filter material is different, and it is sold for four or five hundred yuan a ton in China, and some are sold for one or two thousand. There are generally three reasons:

1. The source of goods is different.

In China, the production areas of garnet are mainly concentrated in Japan, such as Jiangsu, Sichuan, Inner Mongolia, Xinjiang and other places. Especially in Rizhao and Jiangsu, garnet is the most. I heard that the garnet of Rizhao Garnet Mining occupies half of China, and the quality of the ore is also good.

There are some good judgments that may be done by friends, ** higher than the manufacturer, and some are imported from abroad, so ** is higher. I heard that some foreign ones were sold for seven or eight thousand yuan, and I was dizzy.

2. The degree of particle processing.

The processing time of a large particle is shorter than that of a small particle, and the effort is different, and it must be different.

3. The quality of the filter material is different.

Whether the thing is good or not, you will know it after using the comparison, and the garnet has a difference in service life and filtration effect according to the different ingredients.

Garnet filter material is made of aluminum (calcium) silicate minerals with island structure and excitation source, with good mechanical strength, specific gravity, high melting point, stable chemical properties, strong acid resistance and wear resistance, suitable for various water treatment, open air filter and filter tank, is a new type of wear-resistant water purification material. Common specifications: 1-2mm 2-4mm 3-6mm 4-8mm 5-10mm.

The price of different specifications is also different, and sometimes the price will be different due to the limitation of the supply, but it is roughly about 1,000 yuan.

600-1300 a ton range, the number of mesh is different, from 10 mesh to 200 mesh specifications.

The price of garnet itself is determined by the specifications and quality, but if it is only a filter material, it should be about 700 1000. Specifically, it is more accurate to consult with the hail manufacturer.

Common specifications of garnet filter material: 1-2mm 2-4mm 3-6mm 4-8mm 5-10mm Garnet filter material use: garnet can be used not only as a water filter medium, but also as a non-slip road surface, exterior wall coating, rubber filler (such as automobile tire conveyor belt filler, which can increase wear resistance), etc., and is widely used in optical, electronic, mechanical, instrument and other industries.

Garnet has a high specific gravity, and the garnet filter media will hardly flow out when the sewage treatment tank overflows.

Garnet is a natural mineral with very high hardness, low breakage rate, and long-lasting product use.

Garnet filter material is also known as "jade sand" or "natural corundum", Qiao Duan Kai has strong hardness and good acid and alkali resistance, is a kind of island structure of aluminum (calcium) silicate, it is beautiful color, by high purity magnetic selection of gray, red, green, white and other chromosomes, burning old is a new foreign development of three-dimensional spray wall coating, or the only glass shell factory can do color shell sandblasting wear-resistant material. Due to its many internal chemical molecules, good chemical stability and other characteristics.

Garnet filter material is made of natural silicate mineral stone with stable chemical properties and processed by garnet, which has high melting point, specific gravity, high hardness, strong acid resistance and wear resistance, good chemical stability, and is a new type of water purification material that is resistant to eliminating defects. The average chemical composition of garnet filter media is SiO2-38%, Al2O3-19%, FeO-22%, Fe2O3-3%, CaO-12%, MGO-5%, TiO2-1%, and MNO<1%.

Granet is a type of ruby, whose name is derived from the Latin word "granatus", because its crystals resemble pomegranate seeds in the rock.

The crystallization habit of the sedan chair garnet belongs to the equiaxed crystal system hexahedral crystals, and the common shapes are diamond-shaped twelve-sided D, quadrangular three-octahedral N and the convergence of the two.

The average chemical composition of garnet filter media was SiO2-38%, Al2O3-19%, FeO-22%, Fe2O3-3%, CaO-12%, MGO-5%, TiO2-1%, and MNO<1%.

Garnet filter media characteristics:

1) Specific gravity (When the sewage treatment tank or water overflows, there will be almost no garnet filter material overflow, which improves the efficiency of water pollution treatment.

2) Garnet is a physical treatment method, which does not contain free silicon, contains heavy metals, is non-radioactive, and is harmless to the human body.

3) Garnet abrasive is polyhedral structure (generally 12 or 38 masks), compared with ordinary elliptical or round filter materials (activated carbon, sponge iron, manganese sand, etc.), after stacking, there is better porosity (bulk density: , filtration effect is significantly better than other filter materials.

4) Natural non-metallic minerals, high hardness (, low crushing rate, high reuse rate.

5) Acid and alkali resistance, the solubility in acid and alkali is less than 1%.

Garnet filter media is widely used, and in civil engineering, it is often used as sandblasting and anti-corrosion on the surface of buildings.

Manganese sandIt contains mNO2, mnO2 is an oxidation catalyst, ** manganese can oxidize the divalent iron in the water into trivalent iron, and at the same time form a catalytic "active filter membrane" on the surface, and the active filter membrane formed is attached to the surface of manganese sand to further participate in catalytic oxidation, so the pre-treatment effect is better if manganese sand is used as a filter material, the effluent quality is good, and the maturity cycle of the filter material is short.

Garnet filter mediaThe main ingredient is iron-aluminosilicate, which is mainly used to remove suspended particles and impurities in water and reduce the SDI value in water. It is mainly used in physical sewage treatment, which can be used with quartz sand and anthracite, or it can be used separately in mechanical filters.

Garnet filter media is a commonly used sewage treatment material, if you pay attention to the following 3 points when using it, you can better play its performance:

1. Do not expose unused garnet filter material to the sun.

This is mainly because long-term exposure to the sun is easy to cause cracking, which makes the hardness and compressive resistance of the garnet filter material worse. Therefore, when storing it, try to store it separately in a clean place with less dust content.

2. Arrange the thickness of the filter material reasonably.

In the process of laying materials, avoid mixing with other filter materials. The thickness of the spreading material is determined according to factors such as the severity of the sewage and the main impurities of the sewage.

3. Regular cleaning and replenishment.

The long-term use of garnet filter material surface adsorbed impurities are too much, affecting the filtration effect, to be cleaned regularly, regular feeding, generally one to two years to replenish it.

Hope it helps.
