Two-stage Bio-carbon unit for cost-effective zero odour

Project Date



The Challenge

The Tasman District Council had a small WWTP serving a 7500–10500 population which swelled in Summer. 

The BSCB-650 system installed in Motueka, NZ has proven operational success above their performance requirements. Prof Marc Deshusses of the USA has reviewed the above design and agrees that it will meet the requirements based on his extensive experience and research in the USA.
