MAGNETIC ISLAND WATER RECLAMATION PLANT

摘要

The first full scale Membrane Bioreactor (MBR) in Australia, the Magnetic Island Water Reclamation (MIWR) Plant, was commissioned in late 2002. Citiwater Townsville owns and operates the MIWR plant. The plant was designed by GHD and constructed via two contracts. Mineforce were responsible for civil and electrical whilst Aquatec Maxcon (AM) did the mechanical installation. Kubota membrane technology was provided by Aquatec Maxcon via Aquator of the United Kingdom. GHD have supplied on-going technical support to Citiwater since that time. The MIWR has consistently produced effluent quality below licence requirements. Inter alia since commissioning in 2002 up to January 2006 the treated effluent has achieved BOD and suspended solids each < 5 mg/L (80th %ile) and turbidity < 0.3, ammonia-N < 1, Total N < 2 and Total P < 0.2 mg/L (50th %ile). This paper summarises the performance of the plant since the introduction of raw sewage.
