Seminar Details
Wet Air Oxidation (WAO) is a well known technique for the destruction of organics in sludges leading to significantly reduced sludge volumes.
The oxidation reaction normally occurs at high pressures and temperatures. These operating conditions and the specialised equipment needed, usually make the process uneconomical compared to traditional sludge disposal techniques. WAO is therefore normally reserved only for only the most hazardous or toxic compounds where traditional wastewater treatment techniques are ineffective.
However in recognition that waste sludges are a valuable primary resource for nutrients together with the increasingly stringent laws governing the disposal of waste sludges further investigation into this process has been undertaken.
Innovative research at Victoria University (Wellington, New Zealand), and marketed by Wetox Ltd, means that catalysed wet air oxidation is likely to become more affordable and more assessable to industry including food processing companies, or even farms.
This paper outlines the process of wet air oxidation and describes the current innovative research and development being undertaken and the likely benefits to the municipal as well as the industrial wastewater treatment industry.
