The decolorized powdered activated carbon is made from high quality wood, fruit shell and coconut shell by physical method and chemical method, which is carbonized by high temperature steam and activated and refined, it is mainly used for decolorization and purification of tap water, monosodium glutamate, citric acid, amino acid, beer, refreshing beverage, edible oil, food additive and chemical products, sewage treatment and waste incineration power generation.

Due to its strong specific surface area and well-developed pore structure, activated carbon has its own adsorption capacity has given it a very strong decolorization characteristics. Therefore, it is widely used in the decolorization of brown sugar to white sugar in the sugar industry. And the better the adsorption performance of activated carbon, the stronger the decolorization ability.
1) in the two-stage method, in the heavy pigment solution, the powdered activated carbon which had been used once was first treated once, then the new powdered activated carbon was put into the second decolorization, the used powdered activated carbon can be used for the second time, and then used for the crude decolorization.
2) the powdered activated carbon mixed with water is pumped into the decolorization tank, and then filtered with different types of filters. In order to achieve continuous decolorization, granular activated carbon packed decolorization tower, consisting of a series of towers, continuous decolorization, distribution regeneration, the use of powdered activated carbon for filtering decolorization of the process is mostly through intermittent operations to complete. Most of the decolorization methods used in factories are“Two-stage method”, that is, in the case of heavy pigment load, solution impurities, the first decolorization with powdered activated carbon, filter and then through the granular activated carbon decolorization refining. Powdered activated carbon (PAC) is a kind of simple and commonly used separation method, which is used to filter and decolorize, and it is mainly used to separate suspension.
Different decolorization objects, the amount of powdered activated carbon, the concentration of solution with decolorization, decolorization time and temperature, solution time and temperature, solution PH value, etc. , it can be improved and accelerated by pressure, heating and agitation; most importantly, the index of powdered activated carbon is very important, the higher the iodine value and methylene blue index, the better the adsorption effect.
The powdered activated carbon produced by Zhengzhou Jiasheng Water Purification Material Co. , Ltd. can be made into different grades of activated carbon with different adsorption performance, different decolorization ability and different fineness according to the requirements of users. Powdered activated carbon adsorption rate is extremely fast, with flocculation effect and filter aid effect. Good quality, competitive price, welcome to contact us.
