Activated carbon filters
Activated carbon filters work is done through the carbon bed
activated carbon air filter is a more commonly used in water treatment equipment, water desalination system as a pre-treatment can effectively ensure the life of the equipment after class, to improve water quality, pollution prevention, in particular to prevent post-reverse osmosis membrane, ion exchange resin than the free state of oxygen poisoning pollution.
hydraulic fluid filter to collect various forms of pollutants is to filter pollutants and trap material as the filter apparatus. The magnetic absorption of pollutants known as magnetic magnetic filter. There are also electrostatic air cooler filters, discrete filters. In the hydraulic system, where the collection of fluid in the pollution particles are Yigai called hydraulic filters. Currently the most widely used in addition to hydraulic filter material or porous thin gap winding method to intercept pollutants, there are magnetic filters and electrostatic filters used in hydraulic systems.
activated carbon adsorption principle is: the balance of its surface layer of particles on the surface concentration of organic matter in laboratory furniture then adsorbed to activated carbon particles of impurities, the use of the beginning Medical Center of the adsorption is very high. But over time, the adsorption capacity of activated carbon will be reduced to varying degrees, resulting in reduced adsorption. If the aquarium water turbidity, high organic content in water, activated carbon filter will soon be lost. Therefore, the activated carbon should be regularly cleaned or replaced.
activated carbon adsorption capacity and proportional to the time in contact with water, the longer the exposure, the better the water after filtration. Note: The water should be filtered out slowly filter layer. The new activated carbon in the wash before first use clean, otherwise the black ink flowing out. Activated carbon filter before the load should be at the bottom and top of the overlay 2 to 3 cm thick sponge, is to prevent algae and other impurities get into large particles, activated carbon 2 to 3 months after the effect is reduced if the filter should be The new exchange, activated carbon, sponge layer should be changed regularly.
Activated carbon is a very small carbon particles have large surface area, and there are more tiny carbon particles in the hole – capillary. The capillary has a strong adsorption capacity, due to a large surface area of ??carbon particles, so with gas (impurities) to fully brand name underwear contact. When these gases (impurities) to be met by capillary absorption, from the purification. The surface area of ??activated carbon is very important, specific surface area of ??activated carbon BET method of detection data detected only by the result is authentic, there are a lot of domestic equipment can only do a direct comparison method of testing, and now the country will also be eliminated. Unity at home and abroad BET multi-point BET method, worked out at home and abroad than the BET surface area measurements are based on test method standards-based, see our national standard (GB/T 19587-2004) – Principles of gas adsorption BET Determination of specific surface area of ??solid material way. Detection of specific surface area is relatively time-consuming work, the adsorption capacity of the sample, some of the test samples may need to spend a full day, if the testing process does not achieve a fully automated, all the time that testers can not leave, and to high concentration, observation instrument panel, control knobs, too easy to fail the testing process will lead, it will waste a lot of valuable time testers. F-Sorb 2400 tester is the real specific surface area BET method can achieve detection instruments (both direct comparison method), more importantly, F-Sorb 2400 BET instrument is so far the only fully automated detection of the specific surface area of ??intelligent equipment, the test results consistent with the international high stability is also very good, while reducing human error and improve the accuracy of test results.
activated carbon particle size on the adsorption capacity is also affected. In general, the smaller carbon particles, the larger the filter area. Therefore, the total area of ??activated carbon powder largest adsorption best, but powdered activated carbon is easy with the water into the aquarium, difficult to control, rarely used. Granular activated carbon particles formed due to flow easily in water and other impurities in the organic layer of activated carbon filters are not easy to block, the adsorption capacity, portable and convenient replacement.
pretreatment system in the water, activated carbon filter can absorb before the class can not be filtered to remove the residual chlorine level after the reverse osmosis membrane to prevent by its degradation, but also absorption over the previous level leakage of small molecule organic compounds and other pollutants substances, odor in water, colloidal and pigment, heavy metal ions adsorption removal of a more visible role, also has reduced the role of COD. RO water can further reduce the SDI value, to ensure that SDI 5, TOC 2.Oppm.
activated carbon filter’s job is done through the carbon bed. Carbon bed composed of activated carbon particles have a very large number of pores and specific surface area, with strong physical adsorption capability. Water through the carbon bed, organic pollutants in water adsorbed by activated carbon effectively. Besides activated carbon, there are some non-crystalline part of the oxygen tube to groups, so that through the carbon bed of organic pollutants in water adsorbed by activated carbon effectively.

Mechanical filters and activated carbon filter and the flow rate of introduction Introduction
1, mechanical filter
water filters are usually devices, water distribution systems, major equipment, and sometimes used the device into the air. Peripherals in a variety of filters necessary pipes and valves. Mechanical filters are commonly used fiberglass tanks, stainless steel and carbon steel lining of the coating is made of commonly used filter media are: quartz sand, marble, anthracite, manganese ore and dolomite, the granule diameter of about 0.5- 1.5. The filter can be filled with a filler, but also filled two or three fillers.
filter operation is as cyclical, each cycle can be divided into filters, anti-washing and washing three steps.
The purpose of
backwash is to remove the dirt accumulated in the filtering layer to restore the filter layer of the interception capability. It is the filter to run an important step. In order to counter the effect of washing well in the backwash Shihai usually pass into the air.
normal operation of the filter flow rate of about 8 ~ 10m/h, when it runs into the water flow pressure drop of filter layer to allow the limit, stop filtering operation, began to back wash. At this point the filter the water discharged into the upper edge of the filter layer so far, and then into the strong Maternal and Child Supplies degrees to 18-25L/(m?. S) of compressed air, blowing 3 ~ 5min later, in the case continue to supply air to the filter into backwash water, the strength of the filter layer expansion rate should be about 40% to 50% . Finally, water is the first pass down to the water before they began formal filtering operation.
such filters, in addition to the water through filter layer according to the pressure drop to determine the need for cleaning, but also can be run in accordance with a certain time to be cleaned. Allowed to run its cycle, should be obtained by adjusting the test. The filter should always be in the suspended solids through the washing when the party should be slightly in advance, otherwise difficult to clean the filter layer, the long run will generate media agglomeration. Generally allow the pressure drop of about 0.5bar.
2, activated carbon filter
major role in activated carbon filter to remove organics and residual chlorine in water, the water can also remove the odor, color and so on. Typically, the activated carbon are advised to use high-quality shell class to have to ensure good mechanical strength and fast absorption, adsorption capacity, activated carbon has a dual role: first, adsorption; Second, filtration, activated carbon surface and a large number of hydroxyl and hydroxyl functional groups can to online game the nature of the organic matter of various chemical adsorption, and electrostatic forces, and, accordingly, activated carbon can remove humic acid, rich-dimensional acid, lignin sulfonate and other organic substances; organic pollutants (such as phenolic compounds); also able to remove the residual oxidant, free chlorine, odor, harmful gases. Activated carbon can also remove heavy metal ions in water, water in the Hg, Cd, Cr and so on.
activated carbon filter typically run a flow rate of 10-20m/h.
within the activated carbon filter media activated carbon porous structure and the nutritious organic matter, provide breeding environment for the bacteria, therefore, activated carbon filters require periodic disinfection or chemical treatment.
backwash mode: joint air and water backwashing, backwashing strength of 0.5m?/(m?. s), anti-washing time is 10-15min (or backwash flow rate 20-30m/h, backwash Time 4-10min ,3-6 天 anti-wash, filter layer expansion rate of 30% -50%).
carbon life: typically 2-3 years, saturated carbon can be regenerated or replaced. Just loaded activated carbon, first of all must be filled with water, soak for 24 hours or more, to make it fully wet, remove its internal pores when carbon particles in the air, the carbon material does not float in water, and seal the manhole, pressure test, and
Activated carbon filter in the application of power plant water treatment
Abstract: The chemical replenishment contaminated, organic matter content increases, the chemical pretreatment can not get rid of, it is necessary to increase the activated carbon filters remove organic matter, organic matter into the boiler so as not to endanger the safe operation of the boiler.
containing various organic compounds in natural water by coagulation and filtration water treatment can remove the part, but most of the organic matter will enter the follow-up equipment, if the follow-up device is ion exchange resin, the resin it will cause organic pollution; if follow-up treatment is fine filtration – membrane separation, it will cause early failure of precision filter, if the organic matter into the thermal system, it will be broken down into low molecular weight organic acids, affecting the quality of water and steam boilers. Sometimes in order to reduce the organic matter content in the pre-chlorination, and maintain a certain amount of residual chlorine. In order to prevent the subsequent treatment of residual chlorine ion exchange resins and membranes harm must be considered to remove residual chlorine in water treatment have to consider the removal of organic matter will have to consider removing chlorine, activated carbon adsorption is an effective methods. Activated carbon absorption modern cheongsam with the main principle of organic matter and chlorine is the use of activated carbon surface bodies of the physical and chemical adsorption, so as to achieve removal purposes.
1 need
added a thermal power plant water chemistry from the reservoir, through an industrial river connected to the plant. Odd/years, the quality of raw water quality changes very little, the whole operation of chemical desalination system is relatively stable. 1998 8/start, the plant industrial cooling water system to the DC open loop cooling, after cooling, the chemical make-up water in industrial cooling water intake and water intake are with a well, add water, often by the industrial chemical recycled water back the impact of a higher concentration ratio of the chemical circulating water desalination system seriously affect the safe operation; the last two years from the reservoir to the plant was built along the river a lot of industrial plants, industrial waste water discharged by them often river pollution The high salt content and organic matter content of the water desalination system also seriously affected the safe operation of chemical. Although starting from May 2000 has been completely eliminated the impact of industrial circular water, but the industrial waste water discharged by factories along the Hypertension , and water pollution did not decrease, the contrary there is an increasing trend in Table 1 for the past two years, added chemical changes in organic content in water:
can be found from Table 1, when the industry along the river by the impact of industrial emissions and waste water from the filter out of the organic matter content is greatest when the original 6 to 7 times the average has reached 4 to 5 times the original. If the chemical added the long-term water quality does not improve, a large number of organic chemical raw water pretreatment process (that is, inclined tube pool, no valve filter, mechanical filter) and can not be removed, then most of the organic matter will go directly to desalination system, organic matter enters the desalination system, which dissolved the negatively charged carboxylate anion resin and strongly basic ion exchange between, and macromolecular structure of organic matter stuck in the resin gel part of the many tangles, when the first performance for the resin exchange capacity decreased rapidly increasing consumption of acid-base (as in the November 1998 cycle of the plant bed system of yin and yang of water from the normal time of around 10 000 m3 down to about 2 300 m3, showing a large decline in resin exchange capacity, contribute only about a quarter of the original, and because repeated regeneration, an increase in acid-base fees to be about 30 million). Accompanied by partial desalination system is running with a load of organic matter is slowly released, was brought to the water than salt water; and neutral organic and colloidal organic matter directly through the ion exchange resin and with access to water desalination. Once the organic matter into the boiler through the water after boiling in the boiler water temperature thermal decomposition occurs, producing organic acids, as well as a small amount of hydrochloric acid and sulfuric acid. These acids decrease the boiler water pH values ??(such as the 1998 November 19, No.3 furnace plant water pH value fell to 7191), resulting in localized acid furnace wall corrosion, thereby undermining the tube surface protection film of magnetic iron oxide caused furnace tube rupture (such as more than a year after the plant in January 2000 three consecutive 3 boiler pipe explosion, the three burst pipe has been identified as hydrogen corrosion. which boiler water is acidic hydrogen corrosion is an important reason .) At the same time to carry small amounts of volatile acid vapor into the turbine house, causing internal corrosion (eg, June 3, 2000 to find steam separator machine overhaul, leaves and steam room where there are varying degrees of tanks and other corrosion). Visible, due to the presence of organic matter caused serious harm to the follow-up of equipment, the removal of organic matter is particularly important.
2 rehabilitation programs
Through the above analysis, one is the increasing organic matter in water; the other hand, organic matter can not be removed in the chemical pretreatment equipment, then the organic matter in water will enter the boiler with water, organic matter under high temperature in the furnace After a series of reactions caused serious harm to the safety of boiler operation. Must be increased in the desalination system, a carbon filter before, complete removal of organic matter in water. Three existing mechanical filter plant, each rated output is 150 t/h, actually pay about the normal boiler 100 t/h or so, if a mechanical filter will be converted into activated carbon filter, and the remaining two of two mechanical filter rated output is 300 t/h, can meet the need for chemical pretreatment plant. The factory filter system is shown in Figure 1.
rehabilitation programs for the mechanical filter for the 3rd converted into activated carbon filter, then add two valves, the modified system shown in Figure 2. Little change before and after the system transformation, the operation is also very easy
3 to run the program
When they find clean water for organisms increases, the activated carbon filter in use, the specific operation is as follows: open the valve 3G5, 3G4 off valve. If the water to reduce organic matter to the normal state, the activated carbon filter out of operation, the specific operation is as follows: open the valve 3G4, 3G5 off valve. Actual effect is shown in Table 2:
4 Conclusion
1) water quality because the plant chemicals are often contaminated, it must take effective measures to solve.
2) the current transformation of a mechanical filter is activated carbon filter is feasible.
3) changes in the transformation process system less easy to operate, invest less, you can also save a lot of acid-base fee
