Wastewater H₂S Prevention

Prevent Sewer Odors and Corrosion with Superoxygenation. Hydrogen sulfide (H₂S) leads to foul sewer odors, infrastructure damage, and hazardous conditions. Our oxygen-based solutions prevent H₂S formation, eliminating odors and corrosion without chemicals.

Why Prevent Harmful H₂S?

Hydrogen sulfide is more than a bad smell, it corrodes infrastructure, increases operating costs, and creates serious safety risks. Left untreated, it shortens equipment life and forces costly chemical use. ECO₂ stops H₂S at the source with oxygen, protecting critical assets while providing a safer, cleaner, and more sustainable long-term solution.

Odor Control

Eliminate the strong rotten egg smell caused by hydrogen sulfide gas, improving air quality and working conditions for nearby communities and staff.

Corrosion Prevention

Stop the formation of sulfuric acid (H₂SO₄), which rapidly deteriorates concrete surfaces and metal infrastructure in wastewater systems.

Lower Maintenance Costs

Reduce the need for frequent equipment repairs, emergency callouts, and costly chemical treatments by tackling H₂S at its source.

Eco-Friendly Solution

Replace harsh chemical additives with oxygen-based treatment for a safer, more sustainable, and environmentally responsible approach.

How ECO₂ Technology Works

ECO₂’s Superoxygenation System ensures wastewater remains in an aerobic state by maintaining a sufficient level of dissolved oxygen. This prevents the biological formation of sulfides (H₂S), effectively eliminating odors and corrosion risks.

Unlike traditional chemical treatments, which require continuous dosing and generate harmful byproducts, ECO₂ provides a cost-effective, long-term solution with minimal maintenance and low operating costs.

Barbour Lane Pump Station, Ohio River Force Main

Location: Louisville, Kentucky

Project Applications: Wastewater H₂S Prevention

0₂ Capacity: 1900 lbs / day

Why It Matters: When gaseous H₂S reaches sewer infrastructure, it oxidizes into sulfuric acid (H₂SO₄), corroding concrete and steel.
Proven Results: The ASCE Manual for manhole rehabilitation states that H₂S concentrations of 20 ppm corrode concrete at a rate of 1 inch per 5 years.
ECO₂ Solution: By completely eliminating sulfides, ECO₂ technology provides long-term protection against infrastructure deterioration.
