Gas:Solid System

What the experts say...

“Characterized by simple operation, flexible control, and reliable production of chlorine dioxide gas on demand, this [CDG Gas:Solid] process resolves essentially all of the problems associated historically with chlorine dioxide generation.”

Geo. Clifford White,

Handbook of Chlorination and Alternative Disinfectants, 4^th Edition

Features and Benefits

Pure chlorine dioxide (>99% purity guaranteed).
No chlorite ion, chlorate ion, perchlorate ion or molecular chlorine in the generated product.
Safe, simple, reliable operation.
Turndown across entire operating range, without compromising purity.
True flow pacing, without recalibration, adjustment or operator intervention.
Small equipment footprint; standard modules can be custom configured.
No bulk storage of chemicals.

At the heart of the Gas:Solid chlorine dioxide generation process is the reaction between chlorine gas and Saf-T-Chlor thermally stable solid sodium chlorite.

2NaClO₂ + Cl₂ → 2ClO₂ + 2NaCl

This reaction produces no by-products—just pure chlorine dioxide gas (in air or nitrogen), free of chlorite ion, chlorate ion, perchlorate ion or molecular chlorine.

CDG Gas:Solid Systems can be used in:

Municipal drinking water treatment plants
Municipal wastewater treatment plants
Industrial wastewater treatment facilities
Cooling towers at petrochemical facilities

Saf-T-Chlor

The CDG Gas:Solid process uses Saf-T-Chlor thermally stable solid sodium chlorite. Saf-T-Chlor material is thermally stable, even on extreme localized heating (>1,000° C) for a prolonged period (>10 minutes). This is in stark contrast to conventional solid sodium chlorite: even on transient (<10 seconds) localized heating (above a trigger temperature of about 200° C), conventional solid sodium chlorite will undergo runaway thermal decomposition.

CDG Saf-T-Chlor cartridges are completely sealed at the factory. Users never come into direct contact with the chemical. In the unlikely event that a Saf-T-Chlor cartridge is punctured, solid Saf-T-Chlor is readily cleaned up; it cannot soak into flammable materials.

EPA-FIFRA registered:

Saf-T-Chlor is an EPA-FIFRA registered anti-microbial pesticide approved for use used in conjunction with Gas:Solid generators.

NSF certified:

CDG Saf-T-Chlor sodium chlorite, used in conjunction with Gas:Solid generators, is certified by the National Sanitary Foundation (NSF) under NSF/ANSI Standard 60 for drinking water treatment.
