The main reason for the inhibition of coconut shell activated carbon adsorption
Some organic matter in coconut water in drinking water is difficult to be oxidatively decomposed by microorganisms or general oxidation methods, such as phenol, benzene, petroleum and its products, pesticides, detergents, synthetic dyes, amines and many synthetics. Organic substances, after biochemical treatment, are difficult to meet the standards for discharge in water bodies with high emission requirements, and also seriously affect the reuse of drinking water, so deep treatment is required.

Is the water filtered by coconut shell activated carbon plus resin healthy?
Is the water filtered by coconut shell activated carbon and resin healthy? Some water purifiers are mainly filtered by activated carbon, resin, etc., which are easy to breed bacteria, pollute water sources, and fail to achieve the effect of clean water. Now, there is an ultrafiltration on the market. The filtering technology has solved the defects of the previous water purifier, filtered out the harmful substances in the water, and retained the minerals beneficial to the human body. Therefore, when choosing a water purifier, be sure to ask the filtration technology and filter material to see if it meets your own needs.
Is the water filtered by coconut shell activated carbon plus resin healthy? As health has become a hot topic nowadays, more and more people are paying attention. The first question to be concerned about health is how to use clean water, how can we drink healthy water? With the rapid development of the domestic water purifier industry, the kitchen water purifier will solve these problems? What should be chosen? The water purifier? The answer is simple. In addition to the selection of the above filter elements, we must add the above several precautions, whether there is a perfect after-sales service system. Many consumers can't find the address of the repair service phone or the repair service company after purchasing some brands. This situation makes the consumers helpless and wastes resources. Many water purifiers have become furnishings. The water purifier is mainly concentrated on the replacement of the filter element after the sale. If the filter element is not replaced for a long time, it will pollute the water source, and the water purifier will also become a "sewage device". Therefore, the choice of water purifier must choose a perfect after-sales service. For example, the customer service system is used to track customer information, prompting customers to periodically replace the filter element.
What is the main reason why coconut shell activated carbon is hindered in the drinking water process?
Coconut shell activated carbon adsorption is based on conventional feed water treatment. It is usually set after sand filtration. It can also be combined with sand filter material to filter double-layer filter material or coconut shell activated carbon filter instead of sand filter. In the process of deep treatment of drinking water by coconut shell activated carbon adsorption, it was found that a large amount of microorganisms were grown on the coconut shell activated carbon filter material, which improved the effluent water quality and prolonged regeneration, thus developing a cost-effective way to remove micro-polluting in water.

The main reason for the inhibition of coconut shell activated carbon adsorption
The production process of coconut shell activated carbon, the process is raw water - (adding coagulant) - clarification - filtration (adding ozone) and then using coconut shell activated carbon adsorption, and finally effluent.
[Main factors affecting the treatment of coconut shell activated carbon drinking water]
1 properties of coconut shell activated carbon adsorbent
The larger the surface area of ​​coconut shell activated carbon, the stronger the adsorption capacity; coconut shell activated carbon is a non-polar molecule, easy to adsorb non-polar or low-polarity adsorbate; coconut shell activated carbon adsorbent particle size, pore structure and Distribution and surface chemistry also have a large impact on adsorption.
2 properties of coconut shell activated carbon adsorption
Coconut shell activated carbon depends on its solubility, surface free energy, polarity, size and unsaturation of adsorbate molecules, concentration of attached substances, etc.
3 coconut shell activated carbon drinking water PH value
Coconut shell activated carbon generally has a higher adsorption rate in an acidic solution than in an alkaline solution.
The pH value of coconut shell activated carbon affects the state and solubility of the adsorbate in water, thus affecting the adsorption effect.
4 coconut shell activated carbon coexisting substances
When a variety of adsorbates are coexisted, the adsorption capacity of coconut shell activated carbon for an adsorbate is poorer than that of a single adsorbate.
5 coconut shell activated carbon temperature
Temperature has little effect on the adsorption of coconut shell activated carbon
6 coconut shell activated carbon contact time
It should be ensured that the coconut shell activated carbon has a certain contact time with the adsorbate, so that the adsorption is close to equilibrium and the adsorption capacity is fully utilized.
[Application of coconut shell activated carbon adsorption method in water treatment]
Coconut shell activated carbon adsorption is widely used in urban drinking water treatment, drinking water and industrial drinking water treatment.
(1) coconut shell activated carbon urban drinking water treatment
Some organic matter in drinking water is difficult to be oxidatively decomposed by microorganisms or general oxidation methods, such as phenol, benzene, petroleum and its products, pesticides, detergents, synthetic dyes, amines and many synthetic organic substances, biochemical After treatment, it is difficult to meet the standards for discharge in water bodies with high emission requirements, and it also seriously affects the reuse of drinking water, so it requires advanced treatment.
