Odour Treatment Technologies
Odour control systems for identified odour sources require containment (cover with local exhaust) and treatment and must be designed and installed as an integrated package
Nature of Typical Wastewater Odours
Odours are generated during the conveyance and treatment of wastewater due to the degradation of organic matter by micro-organism under anaerobic conditions.
The range of odorous constituents in such biogenic odours is very wide and they include: hydrogen sulphide, ammonia, thiols and other organic sulphur compounds, mercaptans, amines, indole and skatole, volatile fatty acids and a wide range of organic compounds produced by Anaerobic fermentation
Treat Odour Problems for Odour Only After Removal of Identified Hazardous Chemicals
Performance of odour control systems are determined by odour removal efficiency in odour concentration units (ou/cu.m) and measured according to MS1963:2007 (BS EN13725:2003).
In our BIORID® Pre-Scrubber section, hazardous chemicals and solid contaminants are removed from the odorous gases.
The gases, which are now pre-cleaned, humidified and cooled but still odorous, are then passed on to the BIORID® Biofilter where the biological processes will reduce the odour concentration units down to an acceptable final emission level.
This biological odour treatment is characterised by the ability of the selected micro-organism to convert unwanted contaminants into harmless end products.
