OFR Technology THE DADI Technology HYDROXYL RADICAL

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 Molecular orbital of the hydroxyl radical of hydro-peroxides (ROOH) or, in with unpaired electron 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" 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.

OFR Technology THE DADI Technology HYDROXYL RADICAL

1. 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.

2. 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
