Which type of activated carbon is used in water purification and water treatment?

Released Date: Oct 19,2015 Article Source: Yuanlai Water Treatment

Activated carbon can be classified into wood-based carbon and coal-based carbon according to the raw materials used in production. Activated carbon made from raw materials such as wood, sawdust, fruit shells, and plant fibers is called wood-based carbon. Another type of activated carbon made from lignite, peat, bituminous coal, semi-bituminous coal and anthracite is called coal-based carbon. If classified by particle size, there are powdered carbon (less than 200 mm) and granular carbon (1.6-3.2mm). If classified by application, there are catalyst carrier carbon, recovery adsorption carbon, desulfurization and decolorization carbon, and activated carbon for water purification. Finished activated carbon is a black solid substance with no odor or taste. Its main component is carbon, accounting for over 80%, and the rest are hydrogen, oxygen, iron, sulfur, phosphorus, calcium, as well as moisture and ash. It is insoluble in water and solvents. All types of activated carbon are spongy substances composed of microcrystalline carbon. Activated carbon for water purification is generally made from anthracite as raw material and is crushed

Activated carbon for water purification is generally made from anthracite as raw material. After crushing, it is directly carbonized and activated by steam. It appears as irregular granular carbon with a particle size of2~4mmIn the liquid phase, Jun has a relatively high adsorption capacity for both low-concentration and high-concentration organic substances, such as the adsorption amount for phenol being150mg/gIt has a well-developed pore structure, with relatively well-developed filter pores. Therefore, its adsorption of large-molecule organic substances in coal chemical and petrochemical wastewater is superior to that of common activated carbon. Due to its simple manufacturing process and readily available raw materials, it has a relatively low cost and good mechanical strength. Like common granular materials, it can withstand multiple high-temperature regenerations and is a promising low-cost adsorbent. On the other hand, in water treatment, people still prefer to use wood-based activated carbon. Wood-based activated carbon has a large adsorption capacity and high iodine adsorption values and methylene blue adsorption values. Currently, most household or group water purifiers produced are filled with wood-based activated carbon.

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
