Kianga STP Process Options (NSW).

Kianga STP services the Narooma area of the NSW South Coast.  The area is a popular tourist destination, especially during the summer school holiday period.  A capacity assessment undertaken by ASpect identified capacity shortfalls.  The plant struggled to maintain nitrification over the holiday period, when loading increased markedly.  ASpect utilised the detailed operating model that it developed during the capacity assessment to determine the capacity increases associated with four augmentation strategies.  These included the addition of chemical dosing, a duplicate carousel reactor, additional clarifiers and an additional sludge lagoon.  The additional sludge lagoon afforded the option of lowering the reactor sludge age during the short holiday loading period (thereby increasing capacity) and cordoning the resulting biosolids for landfill disposal rather than beneficial re-use.  The detailed, calibrated, operating model afforded precision capacity increase determination and process unit sizing.
