Can activated carbon filtered water be used repeatedly?

Of course. However, the effect and time of repeated use are greatly reduced. Because the activated carbon adsorbs other substances, it is difficult to remove it by general methods, especially the substances like filtered edibles, such as water, which are more difficult to do, and the industrial use is easier to deal with, because the method of processing activated carbon must use substances such as acid and alkali, if it is not cleaned after treatment, it is better not to use it more safely.

You don't want to eat those acids and alkalis.

The treatment method is generally: boil the used activated carbon with water, keep the temperature for more than one hour, then wash it with a large amount of water, and then dry or dry it, and pay attention to the time of use, about one-third of the time of using the new product must be replaced.

Yes, if it is a large-scale device, such as a filter tank, it is best to find an activated carbon manufacturer to regenerate and reuse the activated carbon contained in the filter. If it is a household or a small device, you can find a container to isolate the air and heat it until it turns red, just like the red light of a fire, and then it will be naturally cooled and reused after ten minutes.

Activated carbon has an adsorption capacity for the adsorbed substance, and can not be used again after saturation, if it is to filter the tap water at home, 1 kg of qualified activated carbon can filter about 2 cubic meters of water, I hope it will help you.

Activated charcoal can be used over and over again. It is a carbonized material with a relatively developed void structure, and the pore adsorption will become saturated after the use of the time, and then it is necessary to restore the activity of the product through certain technologies, and exposure to the sun is one of the very good ways, which is relatively simple.

At present, activated carbon has been widely used in environmental protection, industry and civil use, and has achieved considerable results, but after the activated carbon is replaced by adsorption saturation, the user unit will be discarded, buried or burned, resulting in waste of resources and re-pollution of the environment.

Activated carbon adsorption is a physical process, so high-temperature steam can also be used to desorb the impurities in the used activated carbon and restore its original activity, so as to achieve the purpose of reuse, which has obvious economic benefits. The recycled activated carbon can still be used for continuous reuse and regeneration.

Precautions for the use of activated carbon

1. Wash and remove dust before use, otherwise these black dust may temporarily affect the cleanliness of water quality. However, it is recommended not to rinse directly with fresh tap water, because the porous pores of activated carbon can cause damage to the water quality once it adsorbs a large amount of chlorine and bleach powder in the tap water, and then it is placed in the filter for use.

2. It is impossible to clean the clogged debris in the porous pores of activated carbon by simple cleaning. Therefore, it is important to replace the activated carbon regularly to avoid the activated carbon losing its efficacy due to "adsorption saturation". And the timing of replacement should not wait for it to fail before replacing it, so as to ensure that the activated carbon can continuously remove harmful substances from the water quality of the aquarium.

It is recommended to replace the activated carbon 1-2 times a month.

3. The efficiency of activated carbon in treating water quality is related to its treatment amount, which is usually "the effect of treating water quality with more dosage is relatively good".

No problem. In the water pretreatment system, the activated carbon filter can adsorb the residual chlorine that cannot be removed from the pre-filtration to prevent the oxidative degradation of the post-RO membrane.

At the same time, it also adsorbs polluting substances such as small molecule organic matter leaked from the pre-stage, and has obvious adsorption and removal effects on odors, colloids, pigments, and heavy metal ions in water, and also has the effect of reducing COD.

Chemical properties: There are a large number of oxygen-containing groups such as hydroxyl (-OH), carboxyl group (-COOH), etc. on the surface of carbon, which have electrostatic adsorption function, and have a chemical adsorption effect on hexavalent chromium, which can effectively adsorb hexavalent chromium in wastewater, and the adsorbed wastewater can meet the national discharge standard.

The treatment of chromium-containing wastewater with activated carbon is the result of the comprehensive effect of activated carbon on the physical adsorption, chemical adsorption and chemical reduction of hexavalent chromium in solution. Activated carbon treatment of chromium-containing wastewater has stable adsorption performance, high treatment efficiency, low operating cost, and certain social and economic benefits. Therefore, the treatment of chromium-containing wastewater with activated carbon has been widely used.

No, the activated carbon inside the water purifier is like a very thin filter. It can filter out impurities in the water, and if it takes a long time, the impurities will fill the activated carbon itself, and it will not be able to continue to filter impurities.

Therefore, the activated carbon of the water purifier needs to be replaced regularly, and if it is not replaced in time after adsorbing a large number of pollutants, not only the purification effect will become worse and worse, but also cause secondary pollution.

Yes, as long as the strength is there, there is no problem, of course, it needs to be recycled.
