Operational review of the 16,000 EP Whyalla WRP (SBR) for SA Water (SA).

ASpect was the process designer for the Whyalla Water Reclamation Plant (WRP).  The plant had experienced periodic issues since commissioning.  SA Water engaged ASpect to undertake an operational audit of the facilities and operational management.  This included a review of current loading and performance, the adequacy of process monitoring (sampling, analysis, flows and instrumentation) and the automated control philosophy.  ASpect provided 34 recommendations to reduce risk, improve performance and increase capacity.  This resulting in the identification of critical aeration control shortfalls that were the cause of poor settleability and erratic nitrification performance since commissioning.
