Sewage Treatment
December 2005
About this Project
This Sewage Treatment Plant (STP) was designed to treat effluent from a construction camp to a quality suitable for irrigation.
The project utilises the Extended Aeration Activated Sludge method of biological sewage treatment incorporating primary sedimentation tank, aeration tank and secondary clarifier.
The system uses a Gradiant Australia Model 50 mild steel packaged STP with aeration supplied via a “Roots” type blower and diffusers. In addition, disinfection is undertaken using a tablet inline chlorinator prior to discharge.
