Odour and exhaust air treatment at sewage treatment plants with NEUTRALOX® photoionisation

Neutralisation of odours in the exhaust air of industrial plants and in wastewater treatment

Odour emissions occur in many areas of municipal and industrial wastewater treatment, e.g. in sewer systems, sewage treatment plants, sludge treatment, slaughterhouses, milk processing plants, etc. Due to the amendment of the Sewage Sludge Ordinance (AbfKlärV), the topic of odour elimination has recently gained enormous importance in sewage sludge drying and the operation of sewage sludge incineration plants.

The substances released in this process range from organic compounds such as alcohols, aldehydes and ketones to sulphur-containing hydrocarbons such as mercaptans and cadaverine to inorganic substances such as ammonia (NH3) and hydrogen sulphide (H2S). The use of solvents such as acetone and other VOCs can also cause significant odour emissions.

NEUTRALOX® offers effective and reliable methods for treating these and other odour emissions, taking into account the complexity of the odour composition.

How does photoionisation work?

1. UV light generates oxidising agents, ionises atoms and molecules, and breaks down pollutants.
2. Catalysts are used to oxidise harmful substances and odours.
3. The result: effective odour removal

Screen plant  - Sewage pumping stations - Vacuum stations - Screen buildings, headworks - Sand traps - Inlet areas - Pre-clarification - Thickener - Sludge storage tanks - Sludge treatment, e.g. dryer, aerobic stabilization - Dewatering buildings

In waste water treatment plants, Neutralox plants are mainly used in the inlet area, in mechanical cleaning and primary clarification - as well as in all areas of sludge treatment.
