VSP Technology

Source Technologies’ VSP Superoxide Process has been shown to be an excellent oxidizer of hydrogen sulfide and sulfonated organic chemicals known to cause odor in wastewater treatment. Utilizing the VSP Process, the cost for control of these substances is among the lowest in the industry. Further, the destructive reaction kinetics are quite rapid with a 100 ppm solution of hydrogen sulfide being 80% reacted in the first 15 minutes and completely oxidized in less than 30 minutes.

The VSP Process occurs when Source’s VSP catalyst, a complex organic compound, is combined with oxygen, to rapidly generate significant quantities of superoxide ions which are short one electron. These radicals steal electrons from other molecules i.e. sulfide, thus oxidizing them down to sulfur. The VSP Process works over a range of pH from 6 to 9 and when combined with the correct amount of oxidant (O2) in solution, the target organic compound(s) and VSP catalyst are consumed in the process leaving only CO2, salts and water as final products with complete oxidation. The VSP Process can be employed in a variety of applications and is easily adaptable to existing treatment systems.

The VSP Process can replace existing oxidative wastewater treatment systems of any size. Importantly, VSP- based treatment systems are more efficient and provide for lower cost than competing oxidation treatment systems. The design is simple with metered injection of the ingredients, rapid in-line mixing, and adequate retention time being the primary design criteria. Additionally, the VSP catalyst is EPA/T.S.C.A. – certified as “green” for safe use within the environment.

Application of the VSP Process is very straightforward. The process simply requires metering of the VSP catalyst with oxygen into the targeted wastewater with adequate mixing. The reaction occurs quickly thereafter. The VSP chemistry appears to be viable in a pipe for up to 7 hours and as the VSP process occurs at or near neutral pH, there is no need for expensive equipment of special construction for metering the catalyst.

Metering of the oxygen typically requires a commonly available regulator. Oxygen is produced onsite using a molecular sieve and compressor, therefore, eliminating the need for liquid oxygen tanks and periodic refilling. The VSP catalyst is delivered and transferred by Source Technologies. Furthermore, as no hazardous materials are utilized, this technology is environmentally friendly and capital costs are lowered as are the safety risks.

The VSP Process is the latest in a long line of advanced oxidation solutions offered by Source Technologies. Source strives to provide economical, common sense solutions to odor and corrosion. The VSP Process provides more effective oxidation at a lower cost then any other technology in today’s market.
