Oberon STP Concept Design (SBR), for Oberon Council (NSW).

Oberon Council (OC) are replacing their outdated trickling filter plant with a new STP on the same site.  An options report concluded that an IDEA/SBR was the preferred option for the new plant.  OC engaged Hunter H2O to undertake a reference concept design, with a view to delivering the new STP via a DD&C style contract.  Hunter H2O engaged ASpect as a sub-consultant to undertake the process and controls design of the new STP.  The proposed plant consists of a new inlet works, sewage balance tank, SBRs (including reversion to IDEA for stormflow treatment), decant balance task, provision for future teriary filtration, UV disinfection, sludge lagoons, drying beds and phosphorus precipitation.  ASpect’s role included sewage characterisation and loading assessment, process modelling, process design and sizing, P&IDs, control philosophy, HAZOPs, process designer’s report and functional description (controls specification).  ASpect modelled options with and without filtration to ensure both options could be accommodated within the single concept design.
