Important Information On Activated Carbon Philippines Residents Should Have

Activated charcoal or carbon is a form of carbon that has special properties. It is finely ground into fine granules before being treated further to make it an ideal material for chemical reactions and adsorption. The grinding process markedly increases the surface area of the carbon. Substances that may have similar properties include activated coke and coal. There are several things on <a href="http://bfi.com.ph">activated carbon Philippines</a> residents need to understand.
The carbon is produced from a number of raw materials. Those commonly used include peat, wood, petroleum pitch, coconut husks and nutshells among others. Activation is achieved through two main options: chemical and physical. The physical process involves the exposure of raw materials to hot gases in the presence of air. This is done at high temperatures ranging from 600 degrees Celsius and 1200 degrees Celsius.
Chemical activation is achieved by first ensuring that the raw material is impregnated with special chemicals. These include, for example, acids, alkalis and salts such as phosphoric acid, calcium chloride, sodium hydroxide and zinc chloride among others. After the addition of these chemicals the materials are taken through a second process known as carbonization. This is done at a temperature of 450 to 900 degrees Celsius. Generally, most the chemical process is more preferred due to the lower temperature needed.
Active charcoal has an important role in the medical field. Commonly, it is used in the treatment of drug overdoses and in poisoning occurring after oral ingestion. Examples of poisons that may be managed using active charcoal include cyanide, alkalis, acids, lithium, arsenic, ethanol and methanol. It is commercially available as an over the counter drug in the form of tablets. Note that if accidentally inhaled, it may lead to aspiration pneumonitis.
There are a number of environmental and industrial applications that exist. Here, it is mainly used in processes concerned with the removal of pollutants from water and air. They include, for instance, spill clean ups, drinking water filtration, remediation of ground water and the capture of volatile organic compounds (VOCs) derived from petroleum products. As it purifies air it also determines the radon concentration.
Active charcoal is classified in many ways depending on attributes such as surface area, the iodine number, mesh size and ash level among others. Differences in these attributes make different types of charcoal most suited for certain applications. Powdered charcoal for instance is made of the finest granules that average less than a millimeter in diameter. It is most used as an additive to certain processing units such as gravity filters and clarifiers. Granular charcoal, on the other hand, has larger particles and is mainly used for water filtration.
Mercury scrubbing is another important application. This is important in coal power stations and medical incinerators. For the charcoal to be effective for this use, it is first mixed with iodine or sulfur. The mercury binds irreversibly to the charcoal which helps clean the equipment involved. The reluctant compound is usually disposed of in a land fill as long as the concentration of the mercury is less than 260 parts per million.
Activated charcoal is a compound with numerous applications that range from industrial to agricultural to medical. The list has been growing by the day as more uses are discovered. If you have plans of using the charcoal, ensure that you get in touch with an expert. This is because, there are different types all with different physical properties.
