The Hydroxyl Radical

The hydroxyl radical, OH·, is the neutral form of the hydroxide ion (OH–). Hydroxyl radicals are highly reactive and consequently short-lived; however, they form an important part of radical chemistry. Most notably hydroxyl radicals are produced from the decomposition of hydro-peroxides (ROOH) or, in atmospheric chemistry, by the reaction of excited atomic oxygen with water.

Hydroxyl radical is often referred to as the "detergent" of the troposphere because it reacts with many pollutants, often acting as the first step to their removal. It also has an important role in eliminating some greenhouse gases like methane and ozone.

The high oxidizing property of ·OH radicals is highly effective in breaking down long organic chains.

The Hydroxyl Applications in our Technologies


Our new OFR technology is based on the Hydroxyl Treatment Technology. This new technology is extremely effective for the removal of ammonia COD, BOD, organic & industrial waste is using selective catalytic oxidation of pollutants to carbon dioxide, water, and smaller organic and inorganic ions. This process which provides an efficient, stable, simple way that is able to be applied both in low and high concentrations of pollutants removal.

The patented system consists of a low voltage electrode array and specially designed proprietary packing which together creates a three dimensional electrolytic effect.

a. Static Hydro Reactor (SHR)

The Static Hydro Reactor is a proprietary design that utilizes proprietary multi-function media modules and compressed air to breakdown and treat specific pollutants in wastewater.

SHR is ideal for:
  • Removal of dissolved/emulsified mineral oil & grease.
  • Removal of surfactants (detergent, soap, raw materials from cosmetics ).
  • Removal of solvent.
  • Removal of heavy metals.
  • Removal of aromatic compounds including benzene, ethy-benzene and xylene etc.
SHR advantages:
  • High treatment efficiency.
  • Stable outlet water quality.
  • Minimum floor space.
  • Low cost of ownership.
b. Dynamic Hydro Reactor (DHR)

Solution for the cost effective treatment of high concentration organic pollutants from waste water.

DHR is ideal for:
  • Breakdown of Long Chain Hydrocarbon.
  • Removal of soluble COD ( non-biodegradable).
  • Removal of cyanide.
  • Removal of pesticides.
  • Removal of dioxin.
  • Removal of ammonia.
  • Disinfection etc.
DHR advantages:
  • Requires very little maintenance.
  • Electrical cost is minimal. Voltage required is less than 50V.
  • System is robust and simple to operate.
c. The Labyrinth Clarifier (LC)

The LC is very different from other standard industrial clarifier. It consists of a series of oblique plates arranged in parallel with each other. Panels are attached to these plates so that a series of grooves and cells resembling a labyrinth is formed. Through the use of computer modeling, the spacing of the plates and the resultant flow rates are carefully calculated. When wastewater passes through the system, eddy currents are formed in each cell resulting in a series of vortexes within these cells. These vortexes separate the suspended solids from the wastewater which is then drained into a sludge tank at the bottom of the clarifier. The efficiency rate of removing solid is up to 90%.
