Ultra-S3: An efficient, cost effective way to treat hydrogen sulfide (H2S)

Ultra-S3 is an oxidizing system that quickly and effectively breaks down hydrogen sulfide gas (H2S) into elemental sulfur and water and breaks down other recalcitrant organic compounds into primarily carbon dioxide and water.

Over the past decade, Ultra-S3 has been widely used along with an oxidizer (commonly hydrogen peroxide) as a cost-effective way to eliminate the smell emitted by H2S, keep H2S at acceptable levels, and limit the costly deterioration and corrosion it causes to facility infrastructure.

Ultra-S3 is currently used around the world in facilities including landfills, waste water treatment facilities, waste water retention ponds, food processing plants, chemical plants, paper mills, and sewage lines.

How Ultra-S3 works

Ultra-S3 and an oxidant, generally hydrogen peroxide (H202), are injected separately into the waste stream or over the target area containing the hydrogen sulfide gas (H2S) or other recalcitrant organic compounds.

When combined with an oxidant, Ultra-S3 produces hydroxyl radicals, which are highly efficient oxidizers that break down difficult chemical bonds and remediate organic compounds to non-detectable levels.

The benefits of using Ultra-S3

1. Greater efficiency - Through both testing and implementation, S3 has shown to have a significant effect on both the rate and overall efficiency in the breakdown of sulfide when used alongside hydrogen peroxide, as opposed to using hydrogen peroxide by itself.

2. Safe - Ultra-S3 and its chemical components have been classified as non-hazardous under the Toxic Substance Control Act of 1976 (TSCA). It’s also chemically engineered to target problem compounds without destroying environmentally beneficial microbes.

3. Easy implementation – S3 treatment can be implemented within an existing sulfide-treatment infrastructure with minimal capital investment.

4. Greater protection for facilities – S3’s efficiency in breaking down H2S in a facility helps protect its infrastructure from costly deterioration and corrosion caused by the sulfide.

5. Also effective on other compounds - including benzene, methyl tert-butyl ether (MTBE), toluene, trichloroethylene, and many others.


A Proven Process – Case Study

One Northern California wastewater treatment plant used Ultra-S3 to eliminate a serious hydrogen sulfide problem. Although H2S is pungent in low concentrations, it paralyzes the olfactory nerve at levels above 100 ppm to render workers oblivious to the danger.

The wastewater in this plant had hydrogen sulfide levels of 7–10 ppm, which produced concentrations in the sewer air averaging 102 ppm and peaking at 250 ppm. The objective of the S3 treatment was to reduce the H2S concentration in the air to an acceptable level (less than 10 ppm).

The end result? Ultra-S3 process worked rapidly with most of the treatment being accomplished within 3 minutes of contact time. The treatment reduced the hydrogen sulfide concentration in the air to less than 1 ppm, a reduction of approximately 1200 pounds of hydrogen sulfide.
