Although activated carbon is a good adsorption and decolorization product, the dosage is very important during the use process. For the decolorization process, the dosage directly affects the decolorization effect. According to years of experience, activated carbon The amount of decolorization added for the first time should generally be controlled to about 5%, and then added in a certain proportion according to needs until the decolorization standard is reached!

During the decolorization process of activated carbon, there is a certain relationship between temperature and time. The stirring time of adding activated carbon at room temperature is about thirty minutes. If the temperature is too high, the stirring time will definitely be shortened. We would like to remind customers before using When decolorizing activated carbon, in addition to controlling the proportion, the stirring time must be determined based on the water temperature.  

Decolorization of different products depends on the time of adding activated carbon: Soy sauce, vinegar and other substances have relatively high impurity content and require decolorization to meet hygienic standards. For this type of substance, it is recommended to filter the raw materials first, then add an appropriate amount of activated carbon and stir thoroughly. Under the premise of ensuring that the carbon particles are completely dispersed, the longer the carbon addition time, the better the effect will be.

The size of activated carbon particles also affects the decolorization effect. The smaller the carbon particles, the larger the surface area and the stronger the adsorption capacity. However, the cost of small carbon particles is high and there are certain requirements for filtering equipment. It is recommended that manufacturers choose the most appropriate carbon particle size based on actual needs.

 Referring to the production process of soy sauce, approximately 20kg of activated carbon is generally required for every 1,000 liters of soy sauce. However, the specific addition amount needs to be determined according to the quality of the raw materials and decolorization requirements. Experimental research shows that the amount of activated carbon added should not be too much or too little. Too much may increase production costs, and too little may affect the decolorization effect.  

In addition to carbon particles, there is also a black activated carbon powder on the market. Compared with carbon particles, carbon powder is easier to suspend in liquid, so it is widely used in some decolorization processes with higher requirements. However, the turbidity of the suspension of carbon powder is higher than that of carbon particles, and the suspension needs to be filtered before use.

 After adding activated carbon, the liquid needs to be stirred to make the carbon particles disperse evenly. In order to achieve the best decolorization effect, the residence time of carbon particles is generally 6 to 8 hours. If forced to filter in advance or leave the stirring state too early, the decolorization effect may be affected.   Temperature is also an important factor affecting the decolorization effect. The adsorption capacity of activated carbon decreases at low temperatures, while activated carbon decomposes at high temperatures. Therefore, after adding activated carbon, you should ensure that the temperature of the liquid is within a suitable range.

Precautions for activated carbon decolorization

1. Choose high-quality activated carbon The adsorption capacity of activated carbon is closely related to its physical and chemical properties, so when choosing activated carbon, you should try to choose high-quality products. Indicators such as pore size, specific surface area and porosity of activated carbon need to be considered.

2. Storage method The adsorption performance of activated carbon will be affected by factors such as ambient temperature and humidity. Therefore, when storing activated carbon, it should be placed in a dry, cool place to avoid direct sunlight and high temperature and high humidity environments.

3. How to use When using activated carbon for decolorization, you can put the activated carbon directly into the water or add activated carbon in advance. Note that during treatment, the water flow rate and contact time should be controlled to ensure that the activated carbon can fully absorb harmful substances in the water.

4. Replacement cycle Activated carbon usually gradually loses its adsorption capacity during use, so it needs to be replaced within a certain period of time. When using activated carbon for decolorization, it needs to be adjusted appropriately based on the actual adsorbent dose and water treatment capacity, depending on the situation.

5. Operating specifications When using activated carbon for decolorization, operating specifications should be followed to avoid excessive or inappropriate input of activated carbon to avoid negative impacts on water quality. At the same time, you need to pay attention to self-protection during use and avoid contact with activated carbon until the high-concentration adsorbates are treated.
