DAF Commission Check Sheets for the 60,000 EP Orange STP (MLE) for Orange City Council (NSW).

ASpect assisted Orange City Council and CH2MHill in the upgrade and amplification of the dissolved air flotation (DAF) thickener.  The significant upgrade was undertaken in house by Orange City Council staff.  ASpect was asked to prepare pre-commissioning check sheets to guide staff through the detailed pre-commissioning checks necessary to ensure the DAF was functioning as intended prior to introducing WAS.  These checks included checking pumps, instruments, pipework and duties.  The entire control system was also checked including safety and equipment protection interlocks, initial set points, start up and shut down sequences plus automated operating modes.  After following the check sheets, the DAF was able to be commissioned rapidly with no significant faults.
