Wastewater treatment decolorization powder activated carbon

粉状活性炭Mostly made from sawdust and coal as raw materials, it is processed through carbonization, activation, and refining. It has a large specific surface area, strong adsorption capacity, fast adsorption rate, and has flocculation and filtration effects. Due to its low construction investment and operating costs, it is highly favored in water and sewage treatment plants. It has a wide range of applications in the fields of food, medicine, decolorization, crystallization, filtration, and substance purification. It is also the main material of activated carbon filter felt and carbon foam plastic.

We all know that when choosing粉状活性炭When choosing different types of activated carbon based on one's own needs, an important indicator of activated carbon is iodine value. So, how to easily identify the high or low adsorption value of activated carbon without detection equipment?

1. Look directly at the indicators provided by the manufacturer. 2. Judging by volume: To improve the adsorption performance of activated carbon, it is necessary to create as many pore structures as possible on the activated carbon. The more pores there are, the looser the activated carbon will be, and the relative density will also be lighter. Therefore, good activated carbon will have a lighter hand feel. In the same weight packaging, high-performance activated carbon will have a much larger volume than inferior activated carbon. 3. Look at the bubbles. Put a small handful of activated carbon into water, and due to the permeation effect of water, the water will gradually penetrate into the pore structure of the activated carbon, forcing the air in the pores to be expelled, thereby generating a series of extremely small bubbles. Pull out a small bubble line in the water, and at the same time, make a faint bubble sound, which is very interesting. The more severe and long-lasting this phenomenon occurs, the better the adsorption capacity of activated carbon. 4. Check the decolorization ability. Another manifestation of the adsorption capacity of activated carbon is its decolorization ability. Activated carbon has the ability to turn colored liquids into light or colorless onesAbility is actually caused by the adsorption of pigment molecules in colored liquids by activated carbon. The stronger the decolorization effect, the better the adsorption capacity of activated carbon.
