Reference list Case History - Sydney Water Corporation - North Head Odour Control System

Odorgard™ technology is an addition to conventional caustic/hypochlorite scrubbing technology, developed in the UK by ICI Katalco. In an Odorgard™ system the recirculating scrubbing liquid is passed through a relatively small reactor containing a nickel based catalyst. This catalyst enhances the oxidation potential of the scrubbing solution by creating a very strongly oxidizing oxygen free radical that is held on the catalyst surface. This provides a number of benefits:

• Improved scrubbing efficiency on hydrogen sulphide and higher molecular weight sulphides
• Improved scrubbing efficiency on a range of VOC compounds
• Greater odour intensity reduction
• The ability to simultaneously scrub low levels of ammonia and amines
• The virtual elimination of residual chlorine and chlorinated by products in the exhaust gas
• Reduced chemical consumption of caustic and hypochlorite
