Operation and Maintenance

Cutting operational costs

The main operational objective is to achieve acceptable effluent quality while maximizing the aeration performance at minimal costs. It is essential that diffusers be kept clean through cost-effective preventive maintenance procedures:


  • Cleaning the air intake filters
    Filtration equipment maintenance entails cleaning and changing filter media to eliminate air-side (blower filtration system) particulate fouling of diffuser slits.
  • Calibrations of all meters
    Calibration and/or zeroing of meters is necessary as part of preventive maintenance because accurate airflow and DO measurements are a critical part of monitoring aeration systems.
  • Cleaning
    The operator should check the diffusers continuously during operation. Especially the increase of pressure has to be checked. Any increase of pressure may be the result of fouling and clogging.
