The MIOX Blackwater mobile water treatment system has allowed frac and flowback water recycle and reuse in the Fayetteville Shale since Fall 2013. Lab data from samples taken from the produced water retention ponds show superior SRB and APB kill in addition to hydrogen sulfide (H₂S) removal and iron oxidation.
We are pleased to announce our new distribution agreement with Veolia Water Solutions & Technologies for cooling tower water treatment, wastewater reuse, industrial water treatment and downstream oil and gas water applications. This partnership joins two industry experts and marks a major milestone for both Veolia and MIOX.
This new arrangement with Veolia is consistent with the MIOX approach of establishing long-term partnerships with quality companies that have the ability to focus on specific market segments in select geographies. To read the full press release, click here.
“This is an exciting development for Veolia, MIOX technology brings a competitive edge to Veolia’s portfolio by effectively removing biofilm, reducing chemical usage and reducing carbon footprint.”

About Veolia Water Solutions & Technologies
Veolia Water Solutions & Technologies is the Veolia Water subsidiary specialized in technical solutions and design & build projects for water and wastewater treatment, for industrial and municipal clients.
Common chemical oxidation methods for hydrogen sulfide (H2S), an odor causing chemical formed by the action of anaerobic bacteria in water and wastewater systems include chlorine, hydrogen peroxide and ozone. Case studies and laboratory studies performed to date show that Mixed Oxidant Solution (MOS) tends to speed reaction rates or drive oxidation reactions to completion compared to sodium hypochlorite.
The oxidation of H2S is a two part reaction in which elemental sulfur (S0 ) is an intermediate before reaching the fully oxidized state as sulfuric acid (H2SO4). S0 is a solid that must be filtered in municipal applications, so if the reaction cannot be driven to completion with hypochlorite, additional capital equipment must be purchased. With sufficient dosing, MOS does not require a detention tank, filter system, and head can be maintained from the wells to distribution.
- Cl2 + H2S = 2HCl + S0 (reaction may stop here if the hypochlorite dose is not high enough)
- S0 + 3Cl2 + 4H2O = 6HCl + H2SO4
The combined reaction is: H2S + 4Cl2 + 4H2O = 8HCl + H2SO4
MIOX and odor control in wastewater systems: In 2013, a MIOX MOS Zuni system replaced a bleach caustic chemical program in the trickling filter and scrubber system of a wastewater treatment plant in the state of Washington. Since its installation, there have been no complaints from nearby neighbors concerning odors from the plant. The MOS is also used to prevent ponding, or excessive growth of biological material in the media of the filter. Since the introduction of the Zuni system, which uses only salt and power to generate the Mixed Oxidant Solution (MOS), the operators have ceased using the caustic, providing a both safety and cost advantage. MIOX MOS was used also used to successfully replace hydrogen peroxide (H2O2) in a sewer collection system, decreasing the H2S concentrations from 15 mg/L to non-detectable. Because of the distributed nature of the wastewater collection system, using a small OSG system that can be remotely monitored often provides operational flexibility.
MIOX and Advanced Oxidation Processes: More recently, MOX’s on-site generators were used in combination with UV to produce hydroxyl radicals. This process is called an Advanced Oxidation Process (AOP) and was used to remove MIB (2-methylisoborneol), an odor causing algal byproduct from the intake water at a large municipal facility in the United States.
MIOX’s Blackwater™ mobile water treatment trailer provides cost-effective and environmentally responsible produced water management.
The MIOX Blackwater trailer is a mobile water disinfection system designed to meet high volume oil and gas water disinfection needs with ease. This dual-MIOX Mixed Oxidant Solution (MOS) system design allows oil and gas service providers to meet fluctuating water quality, oxidant demand and water volume all within a footprint no larger than 9’ by 40’. Safe oxidizing chemistry generated at your site when you need it, with ZERO hazardous clean-up or spill procedures.
Using MIOX’s patented and innovative technology, oxidant is generated on site and on-demand using just common salt, water and power. The on-site chemical generation process replaces the need to purchase, transport and store biocides, iron chelants and Hydrogen Sulfide scavengers. Capable of treating in excess of 15,000 barrels per day at dosages exceeding 150 mg/l and higher depending on contaminants/constituents in the water, MOS can help achieve complete kill of both Sulfate Reducing Bacteria (SRB) and Acid Producing Bacteria (APB) while eliminating Hydrogen Sulfide (H2S).
For standard produced water disinfection requirements, the Blackwater mobile disinfection system houses two state-of-the-art on-site MOS generators engineered with superior salt and energy efficiencies.
Creating oxidant on site is cost effective and environmentally responsible, cutting back transportation requirements by up to 80%, reducing carbon emissions and fuel consumption, eliminating middle men and the storage and disposal of chemical containers.
MIOX Blackwater to be deployed to major shale formation this summer and will begin treating produced water for recycle.
