CleanTech 100
Sodium Chlorite Water Treatment for Oilfield Operations
A powerful oxidizing agent used to generate chlorine dioxide on-site for microbial control in frac and produced-water systems.
Overview
CleanTech 100 is a sodium chlorite based oxidant used to generate chlorine dioxide on-site for frac and produced-water treatment.
It provides selective microbial control across high-TDS and variable water conditions, helping protect assets, improve water quality, and support higher reuse rates in hydraulic fracturing programs.
Use Cases
Microbial control in frac and produced water
Corrosion and H₂S mitigation in water systems
Water recycling and reuse operations
Outcomes
Reduced microbial load across diverse water chemistries
Improved protection of tubulars, tanks, and pipelines from microbially influenced corrosion and souring
More consistent, reuse-ready water quality for large frac campaigns
Features
CleanTech 100 is a core piece of the Water Treatment platform, working alongside bleach, peracetic acid, hydrogen peroxide, and PAC to prepare, protect, and condition water before drilling begins. It is used where operators need robust microbial control and souring mitigation while enabling aggressive water recycling strategies.
-
Sodium chlorite precursor for on-site chlorine dioxide generation
-
Effective against sulfate-reducing and slime-forming bacteria in high-TDS frac water
-
Selective oxidant that targets microbes and problem species while minimizing impact on friction reducers when dosed correctly
-
Supports control of odor and dissolved H₂S in water systems
-
Compatible with central water-treatment, pipeline, and on-location frac setups
-
In field use, sodium-chlorite-based programs have been used to lower bacterial counts, manage H₂S, and support higher reuse percentages in frac-water systems. CleanTech 100 is applied as part of integrated water-treatment trains to maintain consistent water quality from source, through storage, to the blender.
Supports low bacterial counts in high-TDS reuse water
Helps reduce odor and sour conditions in storage ponds and tanks
Contributes to more stable friction reducer performance by controlling biological loading upstream
-
Continuous or batch treatment of source, produced, and flowback water at central recycling facilities
Treatment of storage ponds, above-ground tanks, and pipeline loops feeding frac locations
On-site dosing ahead of the blender to maintain microbial control during active frac stages
Programs targeting souring control and odor reduction in water systems tied to H₂S
Water-treatment providers, production and facilities engineers, frac and completions engineers, and midstream water managers.

Form and Delivery
Supplied as a sodium chlorite solution designed for use in chlorine dioxide generation systems.
Fed via metering pumps into on-site ClO₂ generators or directly into treatment points as specified by EOS programs.
IntegrationIntegrates with existing water-treatment infrastructure, including storage ponds, tanks, pipelines, and modular treatment units.
Can be combined with coagulants, oxidants, and filtration systems as part of a staged treatment train designed by EOS and the operator.

CleanTech 100 is a sodium chlorite based oxidizing product. Final hazard classification, physical hazards, and environmental hazards must follow the latest EOS CleanTech 100 SDS.
Handling & PPE
Use PPE as specified in the SDS (for example, appropriate gloves, eye and face protection, and chemical-resistant clothing where required).
Avoid contact with incompatible materials and follow site oxidizer-handling procedures.
Regulatory notes
Transport classification, regulatory listings, and any special environmental or reporting requirements must be taken directly from the EOS CleanTech 100 SDS.
Always refer to the latest EOS CleanTech 100 SDS for full hazard, handling, storage, transport, and disposal information.

CleanTech 112
Product: Bleach 12.5%
A liquid oxidizing biocide used for on-site bacteria control in frac water systems. CleanTech 112 (12.5% sodium hypochlorite) releases free chlorine to rapidly reduce microbial load in source water, produced water, and flowback, helping protect equipment, reduce corrosion risk, and support frac chemistry performance.
- Microbial control in frac water
- Disinfection of ponds, tanks, and lines
- Oxidant pre-treatment before filtration and treatment
Complementary Services
-
On-the-fly frac pad water treatment using EOS FLY Units to meter oxidants, inhibitors, and H₂S scavengers in real time. Ideal for programs that use CleanTech 100–driven chlorine dioxide for microbial control in reuse and source water.
-
Water-treatment program design and optimization that tunes oxidant, ClO₂, and inhibitor packages to your water chemistry, KPIs, and cost targets. Maximizes performance from CleanTech 100 while helping cut overall chemical spend.
-
Field and lab testing for bacteria, H₂S, oxidant demand, TDS/TSS, and chemistry compatibility. Provides the data needed to select, dose, and monitor CleanTech 100 and companion oxidant chemistries so frac water stays on spec.
Complementary Platforms
From pre-drill conditioning to post-production cleanup, EOS platforms are built to reduce risk, increase uptime, and deliver measurable field performance.
-
CleanTech 100 Series oxidants sit at the core of EOS’s Water Treatment Platform. These chemistries pair with EOS water-treatment services for on-the-fly frac treatment and pond programs, cutting microbes, H₂S, and solids while keeping reuse water consistent, compliant, and field-ready.
-
The CleanTech 400 Series powers EOS’s Remediation Platform, integrating with spill-response and soil-repair services. Products are engineered to treat brine and hydrocarbons in place, supporting closure-ready, low-disturbance site restoration that aligns with regulatory and ESG expectations.
-
The CleanTech 700 Series anchors EOS’s Completion & Production Platform. Green acids and line-flush chemistries work alongside EOS field services to remove scale, clean up disposal and production systems, and keep SWDs and production assets flowing efficiently over the long term.
