STX Catalytic Process

Source Technologies’ STX Catalytic 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 STX 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 minute and completely oxidized in less than 4 minutes. The STX Process chemistry generally will remain viable for up to 4 hours in most wastewater applications.

The STX Process occurs when Source’s STX catalyst, a complex organic compound, is combined with selected oxidizing agents in solution to rapidly generate significant quantities of free hydroxyl radicals. Free radicals oxidize compounds by removing electrons from the compound to achieve stoichiometric balance, therefore, reduction/oxidation is the result and the STX Process works over a range of pH from 6 to 9. With the correct amount of oxidant (i.e. H2O2), the target compound(s) and STX catalyst are consumed in the process leaving only CO2, salts and water as final products with complete oxidation. The STX Process can be employed in a variety of ways and is easily adaptable to existing treatment and collection systems.

The STX Process can replace existing oxidative wastewater treatment systems of any size. Importantly, STX-based treatment systems are usually more efficient and provide for lower cost than competing oxidation treatment systems. A STX Process system requires no materials of special construction and power requirements are absolutely minimal and the design is simple. Metered injection of the ingredients, rapid in-line mixing, and adequate retention time are the primary design criteria.

Application of the STX Process is very straightforward. The process simply requires deploying the STX catalyst with the oxidizing agent into the targeted wastewater with adequate mixing. The reaction occurs quickly thereafter. Since the STX process occurs at or near neutral pH, there is no need for expensive equipment of special construction for metering the catalyst. Metering of the oxidizing agent component typically requires a commonly available PVC or polyethylene metering pump. Importantly, as the STX catalyst is EPA/T.S.C.A.-certified as “green” for safe use within the environment, there are no compounds within the STX catalyst that would cause concern for corrosion of piping or have any negative impact on WWTP processes.

Let Source demonstrate the versatility and cost-effectiveness of the STX Process for H2S treatment in your wastewater treatment system today.
