This table is intented as a guide to common applications for the techniques listed. Variations may be applied in particular circumstances

Wet Scrubbers

Wet scrubbers remove contaminants from a gas stream by passing the stream through a packed structure which provides a large wetted surface area to induce intimate contact between the gas and the scrubbing liquor.

Degassing Towers

Forbes Degasser Towers operate on the principal of passing the water to be treated over a large surface area whilst blowing air against the flow. The resultant mass transfer of gas at the interface of the water and air removes the acid forming carbon dioxide.

Low cost carbon dioxide degassers

Degassing Towers – Non Standard

Ideal for heavy Carbon Dioxide loads

Stripping Towers

Stripping by packed tower aeration offers an effective and economical approach to many VOC contamination scenarios. Relatively high levels of many organic contaminants can be reduced to well below WHO target levels by the stripping process.

Carbon Adsorption

Solvents, volatile organic compounds (VOCs) and other contaminants in the liquids or gas phase can be adsorbed onto activated carbon. The principle of adsorption is based on the highly porous structure of the granular carbon.
