Abu Dhabi Sewer Network — H₂S Elimination Trial
The Challenge
Hydrogen sulphide (H₂S) levels in Abu Dhabi's sewer network reached up to 2,000 ppm — far exceeding safe exposure limits. The rotten egg odour was causing severe community complaints, medical issues, corroding concrete infrastructure, and creating dangerous working conditions for maintenance crews.
The Solution
T3 Hydrox was dosed directly into the sewer rising mains and pump stations. The advanced oxidiser reacted immediately with dissolved H₂S, converting it to harmless sulphate without the need for any infrastructure modifications or capital works.
Outcome
H₂S reduced from 2,000 ppm to non-detectable levels within 3 minutes of dosing. Zero community odour complaints recorded during the trial period. Significant reduction in corrosion indicators. Trial validated T3 Hydrox as a safe, scalable solution for large-scale municipal sewer networks.
Key Results
North West Province — H₂S, COD & E. coli Elimination
The Challenge
Effluent from an abattoir's water treatment facility was turning all three wastewater stabilisation ponds black, attracting significant odour complaints from neighbours. Testing revealed high organic load (COD), E. coli and abnormally high H₂S levels. Standard chlorination was failing to meet discharge standards and was creating harmful disinfection byproducts, while odour suppressants were adding to the COD count.
The Solution
A combined T3 Hydrox and Hydrobiotics programme was implemented. T3 Hydrox provided rapid oxidative destruction of contaminants of emerging concern (CECs) and pathogens, while Hydrobiotics were used to bioremediate the residual organic load — eliminating the need for chlorine entirely.
Outcome
98.5%+ removal of target CECs including pharmaceutical compounds and carcinogenic PAHs. Pathogen counts reduced to non-detectable levels. Chlorine usage eliminated — removing handling risks and harmful byproduct formation. Effluent met all discharge consent conditions within 7 days of full programme implementation.
Key Results
Deepwater Horizon Oil Spill — Bioremediation with Hydrobiotics
The Challenge
The world's largest crude-oil spill — 4.9 million barrels — required rapid, effective bioremediation in an open saltwater environment. The most critical challenge was eliminating carcinogenic polycyclic aromatic hydrocarbons (PAHs), which conventional treatments struggle to address in marine conditions.
The Solution
Hydrobiotics — natural, non-GMO microbial cultures — were deployed across the affected area. Their unique ability to operate in saltwater environments and metabolise the most difficult hydrocarbons, including carcinogenic PAHs, made them the optimal choice for this application.
Outcome
The spill was remediated to acceptable levels in record time. As a result of this proven performance, Hydrobiotics is now the EPA's designated contingency product for any hydrocarbon spill on the US coastline — whether sewage or crude oil and its derivatives.
