This Sewage Treatment Plant (STP) was designed to treat effluent to a quality that complies with the NSW DEC “Use of Effluent by Irrigation Guidelines” and Class A “Queensland Water Recycling Guidelines”. To achieve the required treated water quality, multi-media filtration and UV disinfection was used in the tertiary treatment stage. The treated water is being used for spray irrigation.
This project utilises the Extended Aeration Activated Sludge method of biological sewage treatment incorporating screening, primary sedimentation, aeration and clarification. The system uses a CRS Model 120 packaged STP with aeration supplied via a “Roots” type blower and diffusers. Disinfection is undertaken using UV, followed by pressure differential activated multi-media filtration, prior to storage.
