Granular activated carbon filter

1. Introduction

1. Also known as activated carbon black, it is black powder or granular amorphous carbon. The main raw material can be almost all carbon-rich organic materials, such as: coal, wood, nut shell, coconut shell, walnut shell, etc.

2. Using charcoal, various fruit shells, high-quality coal, and high-quality coconut shells as raw materials, carbonization (simmering furnace), activation (activation by high temperature steam at 800°C in Sleep activation furnace), crushing by physical and chemical methods , screening, air selection, washing, drying and other processes of refining, and then made by removing impurities, activation screening and other processes.

3. Under the same conditions, coconut shell carbon has the best quality and characteristics, and has the largest specific surface area. The market price of coconut shell activated carbon is 25,000-35,000 yuan per ton, the regular factory activated carbon is about 300-350 grams per filter element, and the carbon cost in the activated carbon filter element is about 7.50-12.50 yuan per piece.

2. Function:

1. It has the advantages of developed pore structure, large specific surface area, strong adsorption capacity, high mechanical strength, low bed resistance, good chemical stability and durability. Odorless, tasteless, non-sand, insoluble in any solvent, selectively adsorbs gas, and has high-capacity adsorption capacity for organic pigments and nitrogen-containing alkalis. It can quickly absorb impurities, odors, pigments, pollutants, etc. in the water into its own structure for the purpose of purification.

2. It integrates adsorption, filtration, interception and catalysis. Can remove 99% chlorine, odor and taste, color, colloid, organic matter, (synthetic detergents, pesticides, herbicides, synthetic dyes, trihalomethanes, haloacetic acids, endocrine disruptors), heavy metals (such as mercury, silver, cadmium) , chromium, lead, etc.), radioactive substances, etc.

3. Disadvantages:

1. Long-term adsorption of impurities, organic matter, pollutants, etc., will parasitize a large number of bacteria and microorganisms on the surface of activated carbon, and the adsorption of organic matter will provide nutrients to bacteria and other microorganisms. With the continuous proliferation of bacteria, the total number of bacterial colonies in the water will eventually exceed the standard. At the same time, the microorganisms convert the ammonia nitrogen in the water into nitrite nitrogen, and the nitrite nitrogen increases the nitrite content in the water. Although nitrite itself is not a carcinogen, the nitrosamines formed by its reaction with amines in water are strong carcinogens.

2. There is a large gap between the carbon particles, if the contact with the water flow is insufficient, it will affect the filtering effect.

What is the advantage of activated carbon rod filter?

1. No desorption, no secondary pollution: After a specific process, except for a little black water when it is used for the first time, there will be no black water in the subsequent use, and no secondary pollution will be formed due to adsorption.

2. Dual functions: Because of its abundant and tortuous micropores, it not only has a good adsorption effect, but also has the effect of intercepting relatively large impurities, which can be said to kill two birds with one stone.

3. High removal efficiency, high efficiency and no waste: After the activated carbon is ground into ultra-fine powder and made into a rod-shaped product, the specific surface area will be increased, and the adsorption micropores will also be greatly increased.

4. Wide range of use: The granular activated carbon filter has a single function and is rarely used in combination with other filter materials; while the activated carbon powder can be mixed with a variety of functional filter material powders and processed into a rod-shaped functional filter element, which can specifically remove various water pollution.

The sintered activated carbon filter element processed by the special process of granular activated carbon can increase the filtration accuracy to 1-5 microns after sintering together. In addition to the effect of activated carbon, it also has a certain role of PP cotton.

No matter what form the activated carbon filter is in, the problem of bacteria breeding after a period of use is inevitable.

The sintered activated carbon filter is generally placed in front of the RO membrane, and its main function is to filter the residual chlorine missed by the granular activated carbon and the impurities greater than the filtration accuracy of the sintered activated carbon, so as to better protect the RO membrane.

The activated carbon filter should be replaced every 3-5 months. There is a certain relationship with the water consumption, 3 months for large water consumption, and 5 months for small water consumption

what's the difference between CTO and granular activated carbon cartridge?

(1) Technical differences, the former is organic bonding and then fired at high temperature, the organic binder is carbonized, and micropores are formed, so that the main body of the filter element is 100% carbon material; the latter is plastic mixing and kneading molding, and some carbon particles are Wrapped in plastic, the real and effective adsorption of carbon particles is only 40%.

(2) The former has fine carbon particles, larger than the surface area, using pore technology, the pore size is tortuous, and the ability to absorb pollutants is stronger, and the efficiency of filtering residual chlorine and other organic matter in the water can reach more than 99.9%; the latter has large particles due to technical factors. , smaller than the outer surface area, the pore size depends on the gap of the particles to form a linear pore size, and in the process of processing, most of the micropores of the activated carbon are blocked, the filtration power is low, and the adsorption is not complete. Dirt is weak.

(3) The former has a good decolorization effect, and the color of cola and soy sauce can be completely removed at a filtration rate of 1l/min, which has an excellent convincing effect on the terminal demonstration of the product; the latter can hardly remove the color of cola and soy sauce. Lose.

(4) The former has high filtration precision, more abundant, and guaranteed water taste.

(5) The filtration precision of the former is controllable, and the filtration precision is controllable within the scale of 0.1um-30um, which can meet the different needs of customers and can have some effect of replacing the ceramic filter element; the latter does not have this feature.

(6) The former is more environmentally friendly, and 100% carbon materials are easy to regenerate and reuse, and will not pollute the environment after discarding; the latter degraded organic materials are difficult to regenerate, expensive, and pollute the environment after discarding.
