FREE RADICAL OXIDATION (FRO)

Image of Gradiant's Free Radical Oxidation (FRO) Technology

High-Efficiency Advanced Oxidation of the Most Difficult Organics

Gradiant’s Free Radical Oxidation (FRO) platform includes a range of advanced oxidation processes (AOP) to effectively and efficiently remove COD, TOC, refractory organics, and other non-biodegradable organics from the most challenging wastewaters.

 

AOPs are in-situ treatment technologies that use hydroxyl radicals, the ultimate oxidant, for removal of organic contaminants in wastewater. These are highly effective methods to accelerate the oxidation process. AOP can be combined with components such as ozone, hydrogen peroxide, sulphate, and E-Peroxone to offer powerful treatment of wastewater. FRO technologies can treat up to 50,000 mg/L of COD consistently and cost-efficiently.

 

The FRO platform includes:

  • E-Fenton
  • Fluidized Bed Reaction (FBR) Fenton
  • Fine Bubble Ozonation
  • E-Peroxone

 

Superior to Conventional Ozonation

 

FBO is more cost-effective and outperforms conventional ozonation systems, with its micro and nanobubble generator. Only 5% of the oxidant dosage is needed versus conventional systems — resulting in 50% less energy and chemical consumption. Another advantage of FBO is the floatation effect of the microbubbles which serve to remove TSS during the oxidation process, thereby eliminating the need for downstream solids removal.

Benefits of Free Radical Oxidation

Minimize Total Life Cycle Costs

Treat the Most Challenging Wastewaters

Gradiant’s FRO treats up to 50,000 mg/L of COD consistently and cost-efficiently. FRO technologies are well-suited for industrial wastewaters generated from microelectronics, refining & chemicals, food & beverage, and textiles.

High-Efficiency Design

Patented designs targeted for specific contaminants result in lower retention time than conventional systems, allowing for smaller system footprints. Lower chemical consumption versus conventional technologies.

Low Operating Costs

Only 5% of the oxidant dosage is needed versus conventional ozonation systems — resulting in 50% less energy and chemical consumption. Lower sludge production versus conventional Fenton reaction systems.
