New Activated Oxygen and Photoionisation Odour Control Offering

Date: 03 October 2008

Activated oxygen can be applied inside of buildings to purify room air and improve working conditions. Typical applications include dewatering sludge rooms, sludge storage tanks, headworks, etc. Contaminated air is drawn into the treatment unit, where high voltage ionisation tubes are located, which produce highly reactive oxygen. Clean, fresh air is produced by the inactivation of molecular odours, germs and harmful substances.

Photoionisation is based on the interaction of ultraviolet (UV) light and a catalytic converter. This technology is usually used for applications that consist of highly contaminated off-gas streams. The process removes oxidisable contaminants (such as hydrogen sulphide, ammonia, mercaptans and hydrocarbons) and eliminates odour. Strong oxidants (such as oxygen radicals and hydroxyl radicals) are produced by UV, and the linkages of odour molecules are broken up. Some of the contaminants are oxidised immediately, while others are adsorbed to the surface of the catalyst and are degraded through the interaction of the catalyst and UV light. The catalyst acts as a downstream polishing buffer for peak loads.

According to Brian Magrane, Sales Manager for Enva Water Treatment and Hazardous Waste; “These technologies compliment our existing range of odour control equipment and services, which also includes odour misting systems and carbon filters. All odour generating facilities have to manage their air emissions in order to meet respective legal requirements and also to be good neighbours".

Neutralox Umwelttechnik GmBH has hundreds of successful installations throughout Europe and worldwide. In addition to the installation of this technology, Enva offer a full after-sales service and can also provide long-term maintenance contracts by fully trained service engineers.
