Activated carbon and its applications
Activated carbon for water treatment
Steam activated carbon is used for a large number of applications.
We have vegetable or mineral active carbon that can be served in granulated form, pellet or powder according to your needs.
Granular activated carbon is the most common for water treatment, and can be used for multiple applications:
- THM adsorption after chlorination and its precursors.
- The removal of pesticides.
- Acid-washed grade when we need a low content of inorganic compounds.
- Dechlorination.
- The removal of taste/odours.
- The adsorption of oils, certain solvents and other hydrocarbons.
- Impregnated in silver to prevent biological contamination of the filter.
- Removal of colour.
Activated carbon for the treatment of gases
The activated carbon in pellet is the most used for the purification of gases.
This application has the advantage of being able to impregnate the coals with different compounds in order to increase their effectiveness in eliminating unwanted compounds via chemical sorption.
Some typical applications are:
- The adsorption of volatile organic compounds from the air using a non-impregnated active carbon.
- Elimination of hydrogen sulphide, which produces bad odour in landfills, biogas plants and sewage treatment plants with active carbons impregnated with alkaline compounds such as NaOH, KOH etc.
- Adsorption of mercaptan and other organic sulphur compounds with activated carbon impregnated with potassium iodide.
- Elimination of the smell of ammonia and other alkaline vapours with activated carbon impregnated in acid.
- Retention of formaldehyde and mercury.
Other uses of activated carbon
For personal respirators and gas masks, only highly controlled carbons with very specific impregnations that are officially approved for their particular application can be applied.
Betaquimica offers the full range of these carbons.
- Type A: against certain organic gases and vapours with a boiling point of> 65ºC
- Type B: against certain inorganic gases and vapours (excluding carbon monoxide)
- Type E: against sulphur dioxide and other acid gases and vapours
- Type K: against ammonia and organic derivatives of ammonia
- There are other specialized degrees of respirators to retain mercury and others for formaldehyde.
Betasorb
Betasorb is a pelleted absorbent ideal for the elimination of H2S up to 200 kg/day in any anaerobic gas (natural gas, biogas, synthetic gas … Betasorb S reacts irreversibly with hydrogen sulphide (H2S) to form inert solid salts.
Zeolita
The natural zeolite whose chemical denimination is hydrated sodium potassium calcium aluminosilicate acts as a natural porous ion exchanger to eliminate ammonium, metals and act as a water softener.
The filter products that Betaquímica supplies to its customers are in accordance with the criteria set out in Royal Decree 902/2018 of July 20 on substances for the treatment of water destined *for human consumption following the tests described in UNE-EN standards.
