Analysis of the Causes Affecting the Adsorption Effect of Activated Carbon Filter

The activated carbon filter was designed and manufactured by our company after taking the advice of the majority of users. It changed the original water inlet and sewage direction, making the water purification effect better and more popular among users. This product is a necessary equipment for water treatment such as drinking water and food water. After the turbidity <5 mm / liter of water is treated by the equipment, it can be clear and transparent, dry and mellow, non-toxic, sterile, no odor, and can be directly consumed by drinking water. The activated carbon filter can remove the discoloration, odor and mercury, lead, cadmium, zinc, iron, manganese, chromium and other heavy metals in the clear water, as well as remove the arsenic, hydride, sulfide, residual chlorine and other polymer compounds in the clear water. Radioactive substances such as radon and radium remove and kill bacteria and E. coli and other carcinogens in the water. It is an ideal water supply equipment for drinking water, food, beverage, pharmaceutical, chemical and other industrial purified water. The activated carbon filter has a simple structure and convenient operation and maintenance. Applicable to food, beverage, chemical and other enterprises and institutions with high water quality requirements, also applied to restaurants, hotels, *, stations, terminals. Water supply equipment for industrial water and domestic water.

Activated carbon filter adsorption principle

Activated carbon is a very fine carbon particle with a large surface area, and there are finer pores in the carbon particles - the capillary. This capillary has a strong adsorption capacity and is sufficiently in contact with gas (impurities) because of its large surface area. When these gases (impurities) hit the capillary, they are adsorbed and purify.

The main factors affecting the adsorption of activated carbon:

1 properties of activated carbon adsorbents

The larger the surface area, the stronger the adsorption capacity; the activated carbon is a non-polar molecule, which is easy to adsorb non-polar or low-polarity adsorbate; the size of the activated carbon adsorbent particles, the pore structure and distribution, and the surface chemistry. It also has a great influence on the adsorption.

2 properties of adsorbate

Depends on its solubility, surface free energy, polarity, size and unsaturation of adsorbate molecules, concentration of attached substances, etc.

3 wastewater PH value

Activated carbon generally has a higher adsorption rate in an acidic solution than in an alkaline solution.

The pH value affects the state and solubility of the adsorbate in water, thereby affecting the adsorption effect.
