March 2000 - CAP™ Clean Air Plants use a unique biological process to remove particulates and heavy metals from the air and oxidize organic contaminants and other toxic fumes and gases that cause odors. CAPs eliminate odors by neutralizing contaminants that cause odors, such as solvents, petroleum hydrocarbons, vehicle exhaust, pesticides, and cleaning compounds.
CAPs are an excellent alternative to carbon for odor control or polishing. The CAP's unique spiral flow configuration eliminates channeling that can occur with carbon. Additionally, because CAPs continuously oxidize contaminants, the spiral filters do not become saturated with contaminants. No additional contamination is released from a CAP. The CAP filters do not need to be replaced or disposed.
Case Study No. 1: A northern California gas pipeline company used soil vapor extraction (SVE) to remediate soil at its transfer station contaminated with methane, hydrocarbons, and glycol. Activated carbon, used in conjunction with the SVE system, was not working because of significant moisture and very heavy hydrocarbon load, which required constant changing of carbon beds. Two CAP-350 units solved the problem. Replacing the carbon with the CAPs occupied much less space than the carbon beds and saved approximately $400 per day in carbon replacement costs.
Case Study No. 2: A Delaware state contractor, using soil vapor extraction to clean VOC and MTBE-contaminated soil at a maintenance garage near a public high school, was unable to startup because the untreated vapors exceeded the permitted levels of VOCs and MTBE in air. Application of a CAP-350 to the existing SVE system achieved a destruction rate of 35 pounds BOD (biological oxygen demand) per day and allowed the contractor to start the cleanup.
Case Study No. 3: Commercial printers thoughout the U.S. are affected by solvent fumes released from the use of various solvents and washes to clean the presses between runs. Charcoal, HEPA, and ozone filters don't work on solvent fumes and exhaust fans release the heated or cooled air, increasing energy costs. A CAP-90 placed in the printing press area destroys the fumes during wash-ups. An additional CAP-75 system placed in the lobby, takes care of odors that may be presented to customers.
Case Study No. 4: Odors released from the use of hair permanents, nail polish, and associated products in hair salons are offensive and can cause poor customer relations. A CAP-90 unit, placed in the work area, eliminates the fumes that cause the odors and increase the health and safety standards.
