LIQUID PHASE CARBON ADSORPTION
Adsorption is a process used for removing a soluble substance
from the water. In this process, activated carbon, a solid,
is produced specifically so as to achieve a very large internal
surface (between 500 - 1500 m2/g). Active carbon comes in
two variations: Powder Activated Carbon (PAC) and Granular
Activated Carbon (GAC). The GAC version is mostly used in
water treatment, but powdered carbon has been fed into the
process to adsorb various organics being subsequently removed
in further processes.
Typical components adsorbed by carbon:
- Organic substances such as:
- Oils
- Radioactive Compounds
- Petroleum Hydrocarbons (BTEX)
- Poly Aromatic Hydrocarbons
- Adsorption of halogenated compounds: I, Br, Cl, F
It is also effective in removing a variety of inorganic pollutants.
Both anions and cations have been removed from waters with
activated carbon. The following metals are often removed from
industrial wastewaters by adsorption. Some of the metals are:
Arsenic, Cadmium, Chromium, Zinc, Lead, Mercury, Copper, etc.
It should be noted that if metals are adsorbed, it may not
be possible to have the carbon regenerated by an off-site
supplier and it may have to be disposed of as hazardous waste.
Process Examples:
- Ground Water Purification
- The De-Chlorination of Process Water
- Water Purification
- Wastewater Treatment
Activated Carbon Equipment and Systems
Manchester provides activated carbon systems as stand alone
vessels, complete systems and controls, with on- and off-site
regeneration capability. The modular concept of the Manchester
systems creates a wide range of flow rates and process conditions
to be accommodated. Applications range from a 10 GPM to over
1,000 GPM.
Manchester units are typically designed for 150 psig and
150oF with or without ASME pressure vessel stamps. The distribution
system in the vessels is specifically designed for the application
and constructed of appropriate materials. The type and quantity
of carbon selected depends on your operating conditions. Manchester
designs the system to optimize the performance and capital
expense of your system based on your process conditions.
