Air quality control technologies can be grouped generally into the following 3 methods:

• Adsorption
• Absorption
• Thermal Oxidation

Adsorption: a process in which the pollutant molecules separate themselves from the gas phase and attach themselves to the surface of solid adsorbent. There are 2 types of Adsorption: Physisorption & Chemisorption.

• Physisorption: a physical adsorption process in which the pollutant molecules separate themselves from the gas phase and attach themselves to the surface of solid adsorbent. The binding forces are of the magnitude of van der Waals forces.
• Chemisorption: a chemical adsorption process in which the pollutant molecules separate themselves from the gas phase and attach themselves to the surface of solid adsorbent. The binding forces are comparable to those characterizing chemical compound formation.

Absorption: a physical process in which the pollutant molecules leave the gas phase and become dissolved in the liquid phase. The binding forces are based on the chemical affinity of the pollutant molecules towards the solvents.

Top

Thermal Oxidation: a process wherein combustible materials are mixed at extremely high temperature levels in an oxygen rich environment. It efficiently consumes waste through a chemical oxidation/reduction reactive process at the molecular level.
