Liquid Treatment

Air Stripers Air stripper are the most cost effective way of removing many VOC’s from water.

As contaminated groundwater enters through the top of the air stripper, millions of air bubbles are forced by the blower pressure up through the perforated trays, vigorously aerating the water to a froth and removing volatile contaminants (VOC) as gravity pulls the water down through each tray. This simple, revolutionary technology delivers up to 99% VOC removal, while the low maintenance and easy access cut O & M costs dramatically.

PRINCIPAL Granulated Activated Carbon(GAC) is a porous sponge-like substance. Carbon technologies are used to treat contaminated liquid and vapor streams. The technology involves passing these fluids through a media bed with a large surface area. The large surface area on the carbon is where the chemical compounds are held. Activated carbon has more surface area per gram than other materials. The surface area ranges from 500-2000 m2/g. Because of the diversity in porous area, carbon has a wide range of contaminants that it can treat. The adsorption potential of contaminants to the carbon surface is controlled by van der Waals forces, that is the weak attractive forces between molecules. GACs adsorbs organic material due to the attractive forces between the GAC surface(non-polar) and the contaminant(non polar) are stronger then the forces keeping them dissolved in water or diffused in vapor.
GRANULATED CARBON ACTIVATION Most Carbon is activated using steam. Activation is also accomplished using chemicals. Wood based carbons steam activation involves a two step process, carbonization and activation. Carbonization occurs in an oxygen deficient environment at high temperatures, 700 degree Celsius. Activation of carbon occurs by using steam where temperature of the carbon is raised to 1800 degrees. During the steam process, some of the atoms are volatilized leaving a highly porous media. During the steam process, some of the atoms are volatilized leaving a highly porous media.
Key factors in affecting Carbon Absorption Performance Several parameters can effect influence carbon absorption performance and should be evaluated as part of the design process. They include the competitive absorptive nature of different compounds, temperature, pH and solubility.
Competitive Adsorptive: Strong carbon bound organics can actually push off weaker organics. This process is referred referred to as the “roll off phenomena”. The organic compound is often found in the effluent as breakthrough driving carbon consumption up. Software programs are used to estimate carbon loading equilibrium with several different compounds and predict carbon usage.
Temperature: In vapor phase carbon the ability for carbon is diminished by as much as 20% at 90°F and stops adsorbing and starts to desorb at 125°F. With a liquid the greater the solubility of a compound the more difficult it is to with carbon as the temperature goes up, generally the solubility goes up and the adsorptive capabilities go down.
pH: As the pH of water goes down the solubility organic compounds in water go up and the ability of carbon to adsorb goes goes down(see below). Solubility: The greater the Solubility the more difficult it is for granular activated carbon to adsorb the organic compound
