Activated Carbon Pellets for Air Purification

图片
Activated Carbon Pellets for Air Purification PRODUCT DESCRIPTION Yihang Activated carbon pellets  for air purification is made of high quality anthracite coal, wood or coconut shell. Through the depth of activation and unique aperture adjustment process, the activated carbon has a lot of holes, and the size of the hole slightly bigger than the toxic gases, specific surface area is more than 1300 square flat/g, for benzene, methyl , ammonia and other toxic or harmful gases have highly efficient adsorption ability, It can effectively remove gaseous pollutants and harmful odor substances in indoor air, and then achieve the purpose of reducing pollution and purifying air. It can also be used for disinfection and filtration of gas masks and protective equipment. Activated Carbon Pellets features :  Less impurities, high quality, developed space, strong adsorption capacity. Technical specification  Items  Index Iodine value  mg/g   850~900 CTC  %   ≥40 Particle diameter  mm   0.8 Particle s

How to reduce COD in wastewater?

In the context of rapid economic development, the impact of environmental pollution is becoming increasingly serious. The water pollution caused by sewage discharge is the most direct and serious consequence because it is related to the life safety and quality of life of people. Therefore, it is very important to reduce the discharge of harmful substances in wastewater and increase the utilization rate of recyclable wastewater. So, how to reduce COD in wastewater?   1. What is COD? Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in water samples, which is often expressed by the symbol cod. Cod is expressed in mg / L. COD values detected by water quality monitoring instruments can be divided into five categories. Among them, COD of the first and second categories is less than 15mg / L, which basically meets the drinking water standard. The remaining three COD values can not be used as drinking water. The third type

Honeycomb activated carbon for aquarium water purification

    Honeycomb activated carbon , using high quality and high iodine value of coal, fruit shell activated carbon and organic additives mixture as raw material, with natural adsorbent attapulgite mixed pressing molding, is made through extrusion molding, carbonization and  steam activation. Honeycomb activated carbon is characterized by high iodine value and large specific surface area, small through hole resistance, strong adsorption capacity,  developed  micropores, high adsorption capacity, long service life, etc.   Waterproof  honeycomb activated carbon is used for aquarium water purification. Waterproof  honeycomb activated carbon is a spectral adsorption material. Its has developed void structure, large specific surface area, and very extensive adsorption and purification effect. It can effectively absorb sulfur dioxide, nitric oxide, carbon disulfide, carbon tetrachloride, hydrogen sulfide, as well as benzene, aldehydes, phenols, esters, ketones and other substances. Such as gasol
