What are the factors that affect the service life of coconut shell activated carbon? Compared to other types of activated carbon, coconut shell activated carbon has a unique property: when it comes into contact with adsorbate molecules that are close to each other on its surface, the molecules on one side can be atoms on that surface; even if they are non-polar, this can immediately lead to asymmetry in electron distribution, resulting in the formation of separated electrodes and prompting the corresponding atoms or molecules to break away from those electrodes. In these two sub-electrode problems, they then attack each other with weak electrical forces. Assuming an average time, a very weak gravitational force occurs in the presence of atoms or molecules, which is referred to as a \"Lennard-Jones\" dispersion. Typically, the service life of coconut shell activated carbon in water treatment is 2 to 3 years, but this is a general calendar-based figure. There are many factors that influence the optimal application time; for example, the quality of activated carbon matters. High-quality activated carbon should have a specific surface area of 1000 m2/g, with a mechanical strength of over 90%. When the particles are not easily displaced, impurities such as organic matter in water are less likely to clog the activated carbon filter layer, resulting in stronger adsorption capacity and faster filtration speeds. The particle size typically chosen is between 10 and 24 mesh. Let me tell you the factors that affect the lifespan of coconut shell activated carbon: 1. When the water quality is acidic, its pH value is relatively low ； When the water quality is alkaline, the adsorption capacity of activated carbon for cationic substances decreases. An unstable pH value of the water also affects the adsorption capacity of activated carbon. The adsorption capacity of activated carbon is proportional to the contact time with water. The longer the contact time, the better the quality of the water after filtration. 2. High water temperature: the higher the water temperature, the stronger the adsorption capacity of activated carbon. However, when the water temperature reaches 30°C, the adsorption capacity reaches its limit and begins to decline. 3. The water output: assuming a high volume of water output, the service life of the activated carbon will be relatively shortened, with each kilogram of activated carbon being capable of filtering around 20 tons of water.
