CTO activated carbon rod is composed of the first letters of chlorine (chlorine), taste (taste) and odor (smell), which means a filter element for removing chlorine gas, odor and improving taste. The pore size of the filter element is about 10 microns, which can deeply absorb the color, odor, residual chlorine, fine impurities, sludge and suspended particles in the water. It has adsorption effect on organic matter, bacteria and heavy metals such as iron and manganese. It can process up to 3750 gallons of water (under the condition of 0.2PPM chlorine content as a fixed value), effectively remove more than 95% of VOCs (volatile organic compounds). It is used for the third stage in the pure water machine, and also plays the role of protecting the RO membrane, and the service life is generally 3-6 months.
1. Compressed activated carbon rod: use coal or coconut shell activated carbon powder as raw material, add binder to heat up and compress, and extrude it. The manufacturing process is simple and the equipment investment is small.
2. Composite sintered activated carbon rod: Using high-quality carbon powder and various composite filter materials as raw materials, it is formed by special processes such as stirring, filling, pre-pressing, high-temperature baking and post-processing. The manufacturing process is flexible, and it can manufacture activated carbon filter elements of various shapes and different filtration performances. It can retain to the greatest extent, optimize the void structure and surface area of activated carbon, and the uniform physical bonding can effectively increase the filtration time. In addition to high chemical adsorption capacity, it also has good physical interception and filtration capacity.
3. 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 activated carbon rod and Granular activated carbon?
(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.
