THE HYDROXYL RADICAL

THE HYDROXYL RADICAL

The hydroxyl radical, OH·, is the neutral form

• f 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

• f

hydro-peroxides (ROOH)

• r,

in atmospheric chemistry, by the reaction of excited atomic oxygen with water.

HYDROXYL EFFECTS ON ORGANICS

The hydroxyl radical is often referred to as the "detergent"

• f the troposphere because it reacts with many pollutants,
• ften 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

• rganic chains.

THE HYDROXYL RADICAL

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:
• 1. Static Hydro Reactor (SHR)
• 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.

Solution for the cost effective treatment

• f 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
• 2. Dynamic Hydro Reactor (DHR)
