Do you know how to make activated carbon ?
Posted On 10/21/2020 03:58:22

Making activated carbon is a two-step process. First, the source material (nutshells, coconut husk, peat, wood, or coal) is carbonized – that is, heated to around 600 Celsius in an environment absent oxygen, so it can’t burn – and then activated. coconut shell activated carbon manufacturers Carbon is activated by exposing it to an oxidizing agent – such as oxygen, steam, or carbon dioxide – in a superheated environment (again, around 600 Celsius), which opens up pores on the surface of the carbon, greatly increasing the surface area.


Additionally, this process gives the carbon a positive charge, which attracts particles that pass through the filter and binds it magnetically to the surface.


As air passes through the carbon filter, the regular filter media captures dirt, dust, animal dander, and other particles as the air passes through the filter. wholesale bulk activated carbon The carbon, with its microscopic pores and its positive charge, binds with gasses and odors that are in the air. This is a chemical process known as adsorption. In the case of my friends, paint fumes and construction dust and dirt still in the air.


Just like a regular air filter, over time, the nooks and crannies of the carbon particles get filled with gasses and other particulates, and the filter will need to be replaced.


Usually, a good carbon filter will last for three months, but if you live in a home with exceptionally strong odors, or a lot of dust and dirt – just like my friends – you may need to replace it more often. But with a carbon air filter in your home, you’ll breathe easier.

How to clean aquarium activated carbon correctly?
Posted On 10/21/2020 03:56:56

Activated carbon is a widely used water filtration agent. People have been using this for a long time to preserve their fish tank. If you have an interest in fish keeping, you will know the benefits of using activated carbon in aquariums. But, what happens after the carbon stops working?  How to clean activated carbon for aquariums?


Activated carbon usually has a short life span. When you put it in your aquarium, it starts working right away.activated carbon for air purification  It discards the toxin substances like chlorine and heavy metals. You can see the water getting cleaner, giving off a fresh smell that is healthy for the fish living in the tank.


But it will wear off after a period. The depletion of activated carbon takes almost three or four weeks. Some might not last that long due to the dirty water condition of the aquarium. To utilize it to the fullest extent, make sure your aquarium is clean before putting the Activated Carbon in it.


So, when do you know that your activated carbon has stopped working? It is when you notice the water color turning into a yellow one, but the most significant change will be the scent. You can’t always detect the color change. So if you start getting an odd smell from the water, you will know that it is time to change the carbon.


Sometimes activated carbon gets jammed up by the existing debris of the tank. coconut shell based activated carbon pellet In that case, you just have to clean the charcoal filter, and it will start working fine like before. Cleaning activated carbon is not a hard thing to do. You only need to take some proper measures regarding the cleaning method.


Step 1: First of all, shut off all the electrical connections of the aquarium. If you have any water controlling valve, switch it off as well. Then carefully remove the filter bag from the aquarium.


Step 2: After carefully taking off the filter, move it to a basin or bathtub. Try to avoid spilling the dirty water on the floor.


Step 3: Your filter could have the charcoal in a casing, or in a loose state. Either way, take out the container or the loose charcoal from the filter.


Step 4: Immerse the charcoal into distilled warm water for five minutes. Then again rinse it with running water for several minutes. It will eradicate any extra residues from the charcoal body.


Step 5: After cleaning it thoroughly, take out the activated carbon. Now try holding up the coal near your ear. Can you hear anything? If you can hear faint cracks or crunching sound coming from it, put it back in the filter. If no sound can be heard, then the carbon is no longer functional. You need to replace it.

What is the difference between HEPA filter and carbon filter?
Posted On 10/21/2020 03:55:37

Both HEPA filters and carbon filters work to improve indoor air quality. However, due to differences in filtering capabilities, HEPA and carbon filters are often used in different industries.activated carbon pellets supplier Ideally, both of of these two filters should be used together given that they both filter out different contaminants.This article will explore the differences between the two in more detail below.


HEPA Filters


HEPA filters are some of the most popular and widely known filters on the market. HEPA stands for high efficiency particulate air.


HEPA filters remove 99.97% of contaminants in the air that are 0.3 microns in size, making these filters highly effective at sanitizing the air. HEPA filters are capable of capturing such small particles such things as bacteria, mold, dust mites and pollen. For this reason, not only are HEPA filters found in household vacuums, for example, but they are also used in the healthcare industry, schools and offices.


HEPA filters were originally used in World War II to eliminate the radioactive particles in the air that were affecting soldiers’ respiratory systems. Unlike carbon filters, HEPA filters are not designed to remove odours, smoke, fumes or chemicals. HEPA filters also trap microorganisms, which is why it is recommended to use both HEPA filters and carbon filters.


Carbon Filters


Carbon or charcoal filters were designed to filter out odours, smoke, fumes and other chemicals. Therefore, carbon filters are suitable to commercial buildings where chemicals are common. Carbon filters come in many different forms, including foam, powder, cloth and solid carbon.


In short: charcoal is treated with oxygen, which opens up the pores between the carbon atoms. As contaminants pass through the filter, the tiny pores chemically react and neutralize. ningxia yongruida carbon Once all of the pores have been filled with contaminants, the filter needs to be replaced so that it can remain at optimal performance. Keep in mind that carbon filters can also purify liquids, which is why these filters are also used in coffee machines and when distilling whisky.


In short, HEPA filters are capable of removing dust and other allergens, such as mold, while carbon filters are capable of filtering out smoke, fumes and other chemicals. Both, however, are necessary for improved air quality across many different industries.

What are the applications of activated carbon?
Posted On 10/15/2020 04:07:12

Activated carbon is used in gas purification, decaffeination, gold purification, metal extraction, water purification, medicine, sewage treatment, air filters in gas masks and respirators, filters in compressed air and many other bulk activated carbon pellets


One major industrial application involves use of activated carbon in the metal finishing field. It is very widely employed for purification of electroplating solutions. For example, it is a main purification technique for removing organic impurities from bright nickel plating solutions. A variety of organic chemicals are added to plating solutions for improving their deposit qualities and for enhancing properties like brightness, smoothness, ductility, etc. Due to passage of direct current and electrolytic reactions of anodic oxidation and cathodic reduction, organic additives generate unwanted breakdown products in solution. Their excessive build up can adversely affect the plating quality and physical properties of deposited metal. Activated carbon treatment removes such impurities and restores plating performance to the desired level.


Medical Applications:

Activated carbon is used to treat poisonings and overdoses following oral ingestion. It is not effective for a number of poisonings including with: strong acids or alkali, iron, lithium, arsenic, methanol, ethanol or ethylene glycol.


Incorrect application (e.g. into the lungs) results in pulmonary aspiration which can sometimes be fatal if immediate medical treatment is not initiated. The use of activated carbon is contraindicated when the ingested substance is an acid, an alkali, or a petroleum product.


Analytical chemistry applications

Activated carbon, in 50% w/w combination with celite, is used as stationary phase in low-pressure chromatographic separation of carbohydrates (mono-, di-trisaccharides) using ethanol solutions (5- 50%) as mobile phase in analytical or preparative protocols.


Gas purification

Filters with activated carbon are usually used in compressed air and gas purification to remove oil vapours, odour, and other hydrocarbons from the air. The most common designs use a 1 stage or 2 stage filtration principle in which activated carbon is embedded inside the filter media.Activated carbon is also used in spacesuit Primary Life Support Systems. Activated carbon filters are used to retain radioactive gases from a nuclear boiling water reactor turbine condenser. The air vacuumed from the condenser contains traces of radioactive gases. The large charcoal beds absorb these gases and retain them while they rapidly decay to non-radioactive solid species. The solids are trapped in the charcoal particles, while the filtered air passes through.


Chemical purification

Activated carbon is commonly used on the laboratory scale to purify solutions of organic molecules containing unwanted colored organic impurities.


Sound Absorption

Activated carbon can filter air and water. Sound energy is found within air and water and activated carbon can be used to absorb that energy. With its high degree of porosity in each activated carbon granule, sound energy has numerous areas to enter into and be converted to heat. With the energy change to heat, the process of sound absorption occurs.


Activated carbon in its granule form can be used to absorb middle and high frequency ranges provided the absorbers design lets air pass through the carbon. Activated carbon can also be used inside of diaphragmatic absorption technology to increase the rate of absorption within the diaphragmatic absorber.activated charcoal wholesale price

What are the main functions of activated carbon?
Posted On 10/15/2020 04:06:27

Having pre-filters inbuilt into purifiers is a hefty advantage over cleaners that don’t. This is the first step in the filtration process where the pre-filters job is to capture large particles the main filter usually can’t, or particles that get stuck to it. It prevents debris getting into the main filter, and this is why pre-filters come in handy as an additional strength in filter technology.activated carbon for water treatment


Pre-filters can be vacuumed, washed, or replaced which helps to prolong the life span of your air cleaning unit. If they are washable, it’s a definite plus because you’re getting an efficient, cost saving unit. A pre-filter needs to be replaced at certain times because after using it and battling with harmful pollutants, it can get damaged and particles such as dust, fur, pollen and hair get stuck. If you want to replace or wash pre-filters it’s your choice, but if you really want to keep it safe you can always replace them when you feel the need for it.


Filter technology based on several levels of filtration like the ones utilizing pre-filters are usually more efficient at removing particles because they keep them in instead of releasing them back into the air. However, there are purifiers that don’t utilize pre-filter technology, so be aware of this when deciding which unit suits you best. Not only do pre-filters have their own purpose, they also prolong the life of the main filter, such as a HEPA filter. Additionally, some pre-filters keep the interior of the machine tidy as well which makes it easier to maintain your purifier.


Activated carbon filters are special in a few ways. They tend to capture more dirt and dust than standard filters. These pollutants are usually smaller and harder to catch. Nevertheless, they use chemically engineered carbon to do what they do best. Along with that, they also eliminate unpleasant odors in the room which comes quite in handy. If you’re a smoker, or the house is filled with unwanted smells of any kind, a carbon activated filter is the perfect “accessory” in an air purifier.


Activated carbon is also called activated charcoal which goes through a process with oxygen to open up the pores between atoms. The main function of activated charcoal is to adsorb the odors or colored substances from liquids or gases. Do be aware though that carbon filters can’t be vacuumed or washed, they can only be replaced due to the nature of the job they perform.


There’s also the powerful combination of an activated carbon pre-filter. That’s double the precaution and filtration. Nothing gets through, dust, gases, or smells. Activated carbon filters are rarely used alone to clean the air, but as a helper they work wonders!coconut shell activated carbon company

What types of air filters do you know besides activated carbon filters?
Posted On 10/15/2020 04:05:37

Ultra Violet (UV)


Air purifiers using this technology have a UV lamp installed inside of them; as microorganisms pass by the UV rays radiated from the lamp, cellular or genetic damage occurs, destroying the microorganism. Although UV technology is effective at killing viruses and bacteria, it is best used with a filter system ahead of the lamps. Without a filter system, too many microorganisms get shaded from the light by particulates.ningxia activated carbon


Negative Ion


Negative ion air filtering technology has proven to be less effective than others because it simply masks the polluted air as opposed to actually cleaning it. This type of air purifier does not have the ability to absorb or dispose of the harmful contaminants in the air. The negative ion simply takes the airborne particles out of the air and transfers them to walls and other solid things in the room. When stuck to walls and other surfaces, they have the ability to become re-circulated back into the air. For this reason, I do not recommend negative ion filters.




Ozone air purifiers produce the gas ozone (O₃). Health professionals have refuted the claims made that these devices are safe, and no agency of the federal government has approved of these devices. Exposure to ozone may ignite asthma symptoms and a high enough level can even scar the lungs. Many of the chemicals found in indoor environments take months or years for ozone to react, making them virtually ineffective. Ozone does not remove particles such as dust and pollen. Obviously, I do not recommend ozone filters.




We’ve all heard this term (which stands for High Efficiency Particulate Arrestance), but probably don’t know exactly what it means. HEPA filters must trap at least 99.97% of all particles larger than 0.3 microns; many of the particles caught in a HEPA filter (including many chemicals) are so tiny they can’t be seen with the naked eye. HEPA filters also trap mold, viruses, and bacteria, so they create a more sanitary environment, and of course they also trap larger particles that can cause lung irritation. (Side note: Make sure your vacuum cleaner is a HEPA-sealed model, too.)


Activated Carbon


Activated carbon filters are comprised of trillions of molecular sized pores that have high absorbent and chemical bonding ability. They are very effective at capturing pollutants like chemical emissions, gases, tobacco smoke, and odors. Once captured, these pollutants are not released back into the air. Activated carbon filters are very helpful to people with Multiple Chemical Sensitivity (MCS) because they absorb formaldehyde, which is found in the adhesives used in carpeting, wood paneling, and upholstered furniture. Fragrances, as well as many chemicals found in household cleaning products, are also removed from the air, making the environment much more breathable, especially for babies, children, the elderly, and those suffering from

What components does the sandblasting system include?
Posted On 10/09/2020 03:34:18

Sandblasting uses high-pressure compressed air to propel blasting media on the project. This reliable technique suits a wide range of surfaces and a selection of treatments including a variety of abrasive media. Sandblasting equipment removes contaminants such as stripping rust, grease and old paint to provide surface adhesion for new coatings. Sandblasting systems include these components:


Air blast rooms: These are clean rooms that are environmentally controlled with abrasion media recovery for highly-productive and efficient operations.silicon carbide wholesale


Air blast tumble equipment: This equipment consists of mill driven tumble blast machines that use oscillating nozzles and cyclone separators inside a rubber-lined chamber.


Portable blasting stations: Mobile air blast systems have pressure pots in various sizes for increased productivity in portable configurations.


Blast cabinets, suction and pressure: This stationary sandblasting equipment also ranges in size. It uses a siphon feed system and a balancing pressure regulator to ensure equilibrium inside the blast cabinet.


Bulk blasting systems: These are large sandblasting units available in stationary models or truck-mounted for total portability.

Blast and recovery systems: More sophisticated sandblasting equipment have systems that blast and vacuum simultaneously and avoid any open air contamination.


Cryogenic deflashing systems: Very cold temperatures allow certain surfaces like rubber, diecast, plastic, magnesium and zinc to be deflashed with precision.


Wet blast equipment: Occasionally, sandblasting equipment uses water to eliminate friction heat and prepare surfaces by scrubbing instead of abrasion caused by dry blasting.

Activated Charcoal: Legitimate Health Benefits and Uses
Posted On 10/09/2020 03:33:36

Treated with oxygen, which opens up the millions of tiny pores between its carbon atoms, the end product -- activated charcoal -- is really porous. It has a chalky black texture and can be found in a number of forms from powders to pills to filters and sponges. It’s added to foods like juices, ice cream, even pizza, and cocktails. In Japan, a new jet black “Kuro Burger” even contains activated charcoal. It’s also added to facial masks and toothpaste. Not to mention that it’s used to filter water as well as purifying the air. Its porous nature and squid ink color have made it the ultimate health and beauty trend.bulk activated carbon pellets


Legitimate Health Benefits and Uses


1. Filters water.

Activated charcoal water filters have been around for a while now and they’re great for cleaning up tap water. Activated charcoal can be used in its unprocessed form to remove contaminants like pesticides, heavy metals, and other impurities from your water. These Kishu Charcoal sticks ($18) do the trick very inexpensively for up to 4 months at a time.


2. Reduces gas and bloating.

A study published in the July 1986 edition of the Journal of Gastroenterology found that taking activated charcoal reduced gas and bloating in study participants. In this case, you would take it orally via a pill, and, according to Dr. Axe, dosing is 500 mg at the onset of gas or bloating. Talk to your doctor before consuming activated charcoal pills.


3. Whitens teeth.

Activated charcoal can remove stains from your teeth. But it is abrasive and can damage tooth enamel if its used on a daily basis, says Mia Stern, wellness coach and owner of Organically Thin. It’s recommended that you mix a pinch of activated charcoal powder with your toothpaste and then brush your teeth with it weekly. Let sit on your teeth for three minutes before rinsing well. Homnan activated charcoal powder ($8) and Fine Vine All Natural Teeth Whitening Powder ($20) are both great choices.


4. Adds vibrancy to skin.

Just as activated charcoal works at filtering water, it’s also fabulous for drawing impurities out of the skin, which makes for a great facial mask. Stern says it has an amazing ability to absorb chemicals, poisons, toxins, and even bacteria.. Boscia Luminizing Black Mask ($28) is a great choice.powdered activated carbon manufacturers

Benefits of Bamboo Charcoal Air Purifiers
Posted On 10/09/2020 03:32:22

Bamboo is antimicrobial: By nature, bamboo is antimicrobial which means all the air that passes through the bamboo charcoal leaves when all the bacteria are dead. This makes bamboo charcoal purifiers ahead of the other purifier types since most of them don’t kill bacteria while purifying the air. So, choosing bamboo charcoal as your purifier will give you the extra advantage of killing bacteria in the air on top of purifying it.granular activated carbon price


Bamboo charcoal is a good dehumidifier: Bamboo charcoal has pores that are large enough to allow both air and water molecules to pass through. If air with a slightly high humidity passes through the bamboo charcoal purifier, some of the water will be absorbed by the charcoal and the purified air will leave with the right amount of moisture. On the other hand, if the incoming air is very dry, the charcoal will release some of the moisture into the air which in turn makes the outgoing air more moist.


Bamboo is a natural deodorizer: Most of the artificial air purifiers/fresheners add some form of scent into the contaminated air as a way of dominating the bad smell to make the target space smell better. In cases where the bad odor in the space is so strong, these artificial air purifiers may not do a good. On the other hand, bamboo charcoal doesn’t add any new smell into the air but removes the components that bring about the bad odor in the air. At the end of the purification, the outgoing air comes out with a natural scent that smells fresh to your nose. This is the healthy air that you’re supposed to breathe and not the good scent created by chemicals in the artificial purifiers that could even be dangerous to your health.


It removes all sorts of pollutants from the air: Besides removing the bad odor, bamboo charcoal also removes most of the pollutants from the air that could be dangerous to our health. Some of the pollutants that bamboo charcoal removes include; ammonia, carbon dioxide, benzopyrene, carbon monoxide and other components of smoke that might be present in the air.


Long-lasting: Another reason why bamboo charcoal beats the rest of the purifiers is its capacity to be used for a long time before replacing it. Bamboo charcoal purifiers can last more than one year as long as you reactivate the charcoal every after 2 months. Reactivation means putting your pack of bamboo charcoal in direct sunlight for about 1 or 2 hours. This reactivates all its purifying properties to their original state.


Bamboo charcoal is healthy and eco-friendly: Bamboo charcoal is 100% natural and does not contain any artificial chemicals. With this kind of purifier, the purified air that is distributed in the room will also be natural which is good for the health. It is also safer to dispose off bamboo charcoal bags without worrying that they will have any negative impact on the environment.ningxia yongruida carbon co. ltd
