Activated carbon is a very fine carbon particles have a large surface area, and there are more fine carbon particles in the hole - a capillary. This capillary has a strong adsorption capacity, due to the large surface area of the carbon particles, they are able to fully contact with the gas (impurities). When these gases (impurities) across the capillary is adsorbed from the purification. Activated carbon is a very fine carbon water filter systems particles primary water filter systems filter paper box has a large surface area, and there are more fine carbon particles in the hole - a capillary. This capillary has a strong Activated carbon is a very fine carbon particles have a large surface area, and there are more fine carbon particles in the hole - a capillary. water filter systems Such capillary with the glove box has a strong adsorption capacity, due to the large surface water filter systems area of the carbon particles, they are able to fully contact with the gas (impurities). When these gases (impurities) across the capillary is adsorbed water filter systems from the purification. nature of the larger surface area of activated carbon adsorbent, the stronger the adsorption capacity; charcoal non-polar molecules, easy-to-quality non-woven filter adsorption of non-polar or polar low; the structure and distribution of the activated water filter systems carbon sorbent particle water filter systems size, pore as well as surface water filter systems chemistry, also has a great influence on the adsorption. depends on the nature of the solubility of the adsorbate, the surface free energy, the polarity, the size of the adsorbate molecules and the degree of unsaturation, with a mass concentration of the activated carbon, etc. water PH value in the acidic solution is generally higher than that of the alkali solution, The adsorption rate. PH value will have an impact in the presence of adsorbate state and solubility in water, thus affecting the adsorption effect. The surface area of activated carbon activated carbon adsorption principle is very important, the specific surface area of activated carbon test data only using the BET method detected the result is authentic, there are many domestic instrument can only do direct contrast detection, the country now has also been eliminated. At home and abroad water filter systems than the surface area of the test unified multi-point BET method, at home and abroad to develop the specific surface water filter systems area measured by standard test methods are based on the basis of BET, see our national standard (GB / T 19587-2004) - BET gas adsorption principle solid material method for determining the specific surface area. The specific surface area detection is actually relatively time-consuming work, due to the adsorption capacity of different samples tested some samples may need to spend a full day's time, if the test process is not fully automated, and that testers can not leave at all times, and to highly concentrated, observe the instrument panel, control knobs, a little inattentive will lead to the failure of the testing process, which will waste a lot of valuable time testers. F-Sorb 2400 tester is truly specific surface area BET method enables detection instruments water filter systems (both direct contrast), and more importantly than the surface area of the F-Sorb 2400 tester is so far the only fully automated intelligent than the surface area of the testing equipment high test results with international consistency, stability is also very good, while reducing human error and improve the accuracy of test results. Maintenance of long-term without filtration equipment, filters must be cleaned, unplug the filter, wash drying, sealed in plastic bags to store not contaminated, wipe the filter efficiency filter storage, not damaged. To change the filter down when immersed in the acid-base washes, the soaking time should not exceed 24 small strainer, the acid-base water filter systems fluid temperature is generally 25 -50 . Recommend acid or alkali with water is better than 10-20%. High protein water filter systems content of the filtrate, filter, preferably with an enzyme solution soak, cleaning effect, updated re-use, must be cleaned and then steam sterilization, cleaning and disinfection of water filters and filter drier is very important. Filter sterilization should be careful to take the time and temperature, preferably polypropylene to 121 high temperature sterilization cabinet, with steam sterilization at 0.1MPa steam pressure to 130 / 20 minutes is appropriate, polysulfone and Teflon steam sterilization, can reach 142 , pressure 0.2MPa, water filter systems for 30 minutes water filter systems or so, if the temperature is too high efficiency filter, time is too long, too much pressure can damage the filter.
