What is the Plate Activated Carbon Filter?

Activated carbon filter function:

The activated carbon adsorption filter cylinder body adopts the design of hydraulic simulation long diameter, and adopts high-efficiency activated carbon with reasonable particle size and specific surface area greater than 1000 g, so that it has the functions of both upper special effect filtration and lower high-efficiency adsorption, which greatly improves the degree of permeate purification and the service life of carbon.

Residual chlorine content of water treated by activated carbon adsorption filter: .

It has outstanding properties on odors, organic matter, colloids, iron and residual chlorine in water bodies.

It also has a good effect on reducing the turbidity and color of the water body, purifying the water quality, and reducing the pollution of the follow-up system (reverse osmosis, ultrafiltration, ion exchanger).

Filtration process: the filter material in the activated carbon filter adsorber, the bottom can be filled with meter-high quartz sand suction, as a support layer, the particles of quartz sand can be used as 20-40 mm, and the quartz sand can be filled with rice granular activated carbon as a filter layer. The filling thickness is generally 1000 2000mm.

Before the activated carbon filter is charged, the quartz sand at the bottom of the filter material should be tested for the stability of the solution, and after soaking for 24 hours, the following requirements are met: the increase in the total solids does not exceed 20mg l. The increase in oxygen consumption does not exceed 10 mg l.

After immersion in alkaline media, the increase in silica does not exceed 10 mg l.

The activated carbon filter quartz sand should be carefully cleaned after being rinsed into the equipment, the water flow should be washed from top to bottom, and the dirty water should be discharged from the bottom until the effluent is clear, and then loaded with granular activated carbon filter material, and then cleaned, the water flow is washed from the bottom to the top, and the dirty water is discharged from the top.

The function of the activated carbon filter is mainly to remove macromolecular organic matter, iron oxide, and residual chlorine. This is because organic matter, residual chlorine, and iron oxides are easy to poison ion exchange resins, while residual chlorine and cationic surfactants will not only poison resins, but also destroy the membrane structure and make the reverse osmosis membrane ineffective.

2. Working principle

After the raw water enters the activated carbon filter tank, through the water distributor at the top, the raw water fully enters the activated carbon filter layer, and after the filter material of the 1200mm filter layer, the impurities in the raw water such as suspended solids, particulate matter, flocculents, and gels are removed by adsorption filtration, and the water enters the bottom outlet space through the filter cap of the middle partition plate, and is output from the bottom nozzle, and the filtration step is completed since then. When the filter impurities inside the tank increase, manually open each valve or automatically open the activated carbon filter backwash step, so that the activated carbon filter material can restore the filtration activity and continue to filter the raw water.

Features of activated carbon filters:

Activated carbon is not easy to flow due to particle forming, and impurities such as organic matter in water are not easy to block in the activated carbon filter layer, and its adsorption capacity is strong, and it is easy to carry and replace.

Activated carbon has a biochemical degradation effect and a catalytic effect on the surface.

Activated carbon can remove dissolved organic pollutants in water that are difficult for microorganisms to degrade or cannot be decomposed by general oxidation methods.

The role of the activated carbon filter:

For advanced treatment of feed water:It can effectively degrade, remove color and odor, and improve the quality of drinking water.

For the treatment of brackish water:It can effectively remove the bitter and astringent taste, and make the water quality higher than that of ordinary tap water.

It is used for pretreatment of ion exchange, electrodialysis and reverse osmosis: it can effectively remove organic pollutants and residual chlorine in water, prevent resin pollution and membrane poisoning, ensure the service life of ion exchange resin and membrane, and ensure the normal operation of the system.

Made of SUS304 or SUS316L high-quality stainless steel material, corrosion-resistant and durable, the filter plate of this machine adopts a thread-like structure, which can be used according to different filter media and production processes (primary filtration. Semi-fine filtration. Fine filtration) requires that different filter media be replaced and microporous filter membranes can be used directly to achieve the purpose of sterility.

Users can also reduce or increase the number of layers according to the size of the filtration volume, so that the flow rate is suitable for the filtration requirements, the machine is pressurized and sealed when working, the liquid material is not lost, the liquid clarity is good, the machine can also be specially made according to the user's needs multi-stage filter device, the first level can store coarser filter material, the second level can put finer filter material, which not only saves production time and cost, but also can meet the production needs, all sealing parts of this machine use silicone rubber sealing ring, high temperature resistance. Innocuity. No leakage, good sealing performance and can improve the filtration accuracy, but also can be equipped with a return device, the filter material assembly or cleaning is very convenient, after the pump stops rotating, open the return valve, all the sediment will automatically come out, and at the same time can be used to backflush from the return pipe with clean water.

The activated carbon filter of Shanghai Feizhuo has the characteristics of large surface area and strong adsorption.

It should be an activated carbon filter, with aluminum honeycomb, plastic honeycomb, and paper honeycomb with a through-hole structure as the carrier. Compared with the traditional activated carbon filter, it has better gas dynamic performance, small bulk density, large specific surface area, high adsorption efficiency and small drag coefficient. The honeycomb activated carbon filter is made of powdered activated carbon on polyurethane foam, and its carbon content is about 35%-50%.

It has the efficient adsorption performance of activated carbon and can be used for air purification to remove volatile organic compounds formaldehyde, toluene, hydrogen sulfide, chlorobenzene and pollutants in the air. The air resistance is small, the energy consumption is low, and it can deodorize, remove odor, purify the environment, and have a good purification effect under a certain air volume.

Analysis: Activated carbon, like diamond and graphite, is an allotropic element of carbon, a form of carbon element, honeycomb structure, there are many small crystals, the mechanism of action is adsorption, because of its large specific surface area, there are many voids, small pores, so it has a strong adsorption capacity, can adsorb pigments, toxic gases and toxic buried substances, used for decolorization, purification of water, gas and liquid. It can be desorbed by heating.

Activated carbon, generally using bamboo, wood, fruit and other carbon-containing substances as raw materials, heated at high temperature in the case of air isolation, and continuously introduced water vapor to remove the decomposed water gas, wood tar and other organic matter.

What is Activated Carbon?

Answer: Ordinary activated carbon is a kind of porous substance carbonized by a special firing process, which has a very rich pore structure and a large surface area, which can adsorb odors and harmful gases, but cannot be decomposed. We also have some models that use activated carbon, but we use catalytic activated carbon that has been specially treated, which not only has a good physical adsorption effect, but also has a catalytic decomposition effect on pollutants, and will not form secondary pollution.

There is still a disadvantage compared with photocatalysis, and it still needs to be replaced after a long time, and the function is not as comprehensive as photocatalysis. )

Activated carbon has a very important physical property, that is, adsorption.
