Activated Carbon When does it fail in water treatment:

1. Fruit shell carbon is used for sun lamps and wastewater treatment. Microfiltration is this kind of filtration technology. The particle size range is usually 0.05/10/m, close to the matrix and ultrafiltration membrane. Different from basic filtering, it belongs to the separation and extraction goal driven by working pressure, does not change the phase state, and does not produce page quality migration. Basic filtration is generally divided into deep filtration and filtration filtration. Materials used, such as paper, asbestos, glass fiber, porcelain, cloth, felt, etc. As a porous structure, it has the appearance of its porous structure. The diameter distribution is so wide that it is impossible to indicate its diameter. If you worry too much, the object will be blocked due to the shaking inside the material. Its closure rate B6 is regulated by working pressure, with large material thickness, large particle size and wide application range.

2. The replacement circulation system of shell carbon is related to the leaking water body. Whether the shell carbon is invalid should be determined according to the water content of compounds in carbon import and export trade. After all normal backwashing, determine that the water content of the soil at the inlet and outlet is higher than that of the imported compound. This means that the carbon in the shell has failed and needs to be replaced. The replacement cycle time of shell carbon is usually 1~2 years (the actual time should be determined according to the leakage water body, the carbon filling amount in the shell and the accumulated operation time). Therefore, in understanding the price of carbon, people should also pay attention to how to use carbon in daily life, otherwise I don't know how to use it is not such a waste.

There are many ways to judge the adsorption performance of shell carbon. The simple way is to look at the appearance and quality.

1. Appearance and quality:

The appearance of the shell carbon is black and irregular granular, like columnar carbon and honeycomb carbon, which are generally coal based carbon. The shell carbon has a large specific surface area and well-developed pore structure, so it is relatively loose and light in weight. Compared with other carbon of the same weight, the volume of good shell carbon must be much larger than others.

2. From the perspective of raw materials:

The carbon of coconut shell is better than that of other fruit shells, both in terms of adsorption capacity and quality. The coconut shell has a different manufacturing process from others, and has strong compression resistance and many micropores, so it has good adsorption capacity.

3. Technically:

The shell with good adsorption capacity Activated carbon It will not be rough in process. Just like buying clothes of good quality, clothes of good quality will not have threads, and clothes of poor quality will have many threads. If the carbon surface is very mottled, and there is a lot of dust, not pure black, or the surface is uneven, it will affect the adsorption capacity of carbon. Abstract: How to determine the cause of failure of shell carbon can be understood from the above three aspects, and when to correctly replace the shell carbon. I hope this article can help you understand that there are three knowledge points, so that you can know when the failure occurs!
