DioxPro-2™
Advanced Dual-Precursor Chlorine Dioxide Generator Engineered for Precision. Built for Performance. Trusted for Safety.
Technology Overview
The DioxPro-2™ is a next-generation chlorine dioxide generator based on a dual-precursor reaction between acid and sodium chlorite. Developed for industrial and municipal applications, it provides on-site, on-demand generation of ClO₂ with unmatched control, safety, and efficiency.
Why Chlorite Control Matters
When chlorine dioxide is added to water for disinfection, it doesn’t form trihalomethanes (THMs) or haloacetic acids (HAAs) like chlorine or chloramine—but instead, it degrades or reacts to form chlorite and chlorate.
Chlorine dioxide is a powerful and widely used disinfectant in drinking water treatment. However, it leaves behind chlorite ions (ClO₂⁻) as a primary by-product. Elevated chlorite levels can pose health risks, particularly to sensitive populations, and are strictly regulated under EPA, WHO, and EU guidelines.

Clearion™ | Closed-Loop Chlorite & Chlorate Control with ClO₂ Recovery
Clearion™ is InfraCorp’s proprietary technology that incorporates a gas-phase separation step using vacuum-assisted extraction to remove volatile disinfection byproducts—such as chlorine dioxide (ClO₂) gas—while concentrating non-volatile chlorite and chlorate ions in the liquid waste stream. Within the Clearion™ vacuum contactor, ClO₂ gas and its byproduct ions are selectively separated: the ClO₂ gas is recovered and returned to the main disinfection stream, while the chlorite and chlorate ions are retained in the aqueous phase and reduced downstream via catalytic treatment. This unique, closed-loop system enhances disinfection efficiency, minimizes chemical consumption, and ensures residual oxidants remain safely within regulatory compliance thresholds—preserving the integrity of your water treatment process.
Key Features
- Targeted Chlorite Reduction down to <0.2 mg/L

DioxPro-2™Generation Chemistry
The DioxPro-2™model generatesthe chlorine dioxide in two methods
- Diluted precursors chemical (DioxPro-2D™)
- Concentration precursors (DioxPro-2C™ )
General chemical reaction methods for either models (DioxPro-2D™ orDioxPro-2C™)are :
Method No.1 :
The sodium chlorite–hydrochloric acid method
5 NaClO2 + 4 HCl → 5 NaCl + 4 ClO2 + 2 H2O
Acid-chlorite 2-chemical chlorine dioxide generators represent the highest quality, performance and accuracy available in 2-chemicals chlorine dioxide generators
Method No.2 :
The chlorite–sulfuric acid method:
4 ClO−2 + 2 H2SO4 → 2 ClO2 + HClO3 + 2 SO2−4 + H2O + HCl
Method No.3 :
The chlorite persulfate method:
2 NaClO2 + Na2S2O8 → 2 ClO2 + 2 Na2SO4
The concentration of chlorine dioxide produced by these methods varies between 1 and 3 g/L.
DioxPro-2D™Generators
TheDioxPro-2D™ chlorine dioxide generator is designed to produce and consistently maintain a product yield greater than 95%, which makes it ideal for drinking water treatment.
The DioxPro-2D™ generators and range in capacity from 40-800 g/hr (2.4 – 42.4 lb/day). These chlorine dioxide generators are ideal for applications with low water flow and therefore small ClO2 dose and reactant chemical consumption.
This method of generation Utilizes the following precursors
- Nanocide -DC (7.5% sodium chlorite)
- Nanocide -DA (9% hydrochloric acid)
These chlorine dioxide generators are ideal for applications with low water flow and therefore small ClO2 dose and reactant chemical consumption.
DioxPro-2C™ Generators
The DioxPro-2C™ generators utilizes the following chemical precursors
– Nanocide-CC (31% sodium chlorite)
– Nanocide-CA (33% hydrochloric acid )
– Water dilution
The range of capacity from 150-10,000 g/hr (7.9 – lb/day).
Feed System :

Superior Yield. Lower Operating Cost. Proven Performance.
Chlorine dioxide generation performance varies significantly by technology, directly impacting chemical consumption, operating cost, and overall system value.
Traditional acid–chlorite generators typically achieve chlorite yields of 65–68%, with even lower overall conversion efficiency due to unreacted acid. While this approach remains a cost-effective and simple solution for low-capacity applications, its chemical efficiency is inherently limited.
For customers seeking higher efficiency, reduced chemical usage, and improved lifecycle economics, advanced generation technologies deliver clear advantages. Electrochemical and three-chemical generator systems provide substantially higher conversion rates and product purity.
The InfraCorp Electrochemical RiteDos™ generator sets a new benchmark in performance, producing chlorine dioxide at 95–99% purity with greater than 80% chlorite conversion. Because only a single chemical precursor is required, this high chlorite conversion translates directly into exceptional overall efficiency and predictable operating costs.
Similarly, the chlorine–chlorite process can achieve conversion efficiencies of up to 95%, depending on reaction pH and reactant concentrations, making it an excellent choice for applications demanding maximum yield and chemical efficiency.
