Annual Service Completed – GRAF One2Clean Sewage Treatment Plant
This week we carried out the annual service and performance assessment of a GRAF One2Clean sewage treatment plant for a new homeowner. Having originally installed the system several years ago, it was great to revisit the site and provide guidance on system operation, maintenance requirements, and key indicators to monitor between services.
As part of the manufacturer’s recommended service schedule, a full inspection and operational assessment was completed, including:
✅ Visual inspection of all mechanical and electrical components�✅ Air blower performance and airflow checks�✅ Verification of treatment cycles and control functions�✅ Assessment of sludge levels to determine desludging requirements�✅ Dissolved Oxygen (DO) testing to confirm healthy biological treatment conditions�✅ On-site Ammonia testing to assess treatment efficiency and final effluent quality
We’re pleased to report that all test results were within expected operational parameters, confirming the plant is functioning efficiently and providing effective wastewater treatment.
Following the sludge assessment, it was determined that desludging was not required this year, resulting in a cost saving for the customer while maintaining compliance with service recommendations.
Regular servicing is essential to maximise treatment performance, identify potential issues before they become costly repairs, and ensure environmental compliance.
We service all makes and models of sewage treatment plants, including GRAF, Klargester, WPL,KEE process , Clearwater, Tricel, and many more.
