  • Assessment of diffuser pressure loss on WWTPs in Baden-Württemberg

    Aeration of activated sludge is a critical treatment step for the operation of activated sludge plants. To achieve a cost effective treatment process, assessing and benchmarking of aeration system performance are important measures. A simple means of gauging the relative condition of a fine bubble diffused aeration system is to evaluate the pressure loss of the diffusers as oxygen transfer tests ...

  • Prairie farm rehabilitation administration paper

    The aeration efficiency of two types of aeration devices, air injection and mechanical surface aerators was evaluated in farm dugouts in the Peace River Region of Alberta. The air injection systems were tested using three types of diffusers; open-ended tubing, linear fine bubble diffusers and a membrane diffuser. Our results indicate that without aeration, anoxia can develop in the bottom of ...

  • Oxygen, the fix for pond problems

    Aeration of a water feature should have three main considerations. These include preventing thermal stratification, balancing the dissolved oxygen levels throughout the water column from the sludge or benthic layer to the surface and balancing temperature levels throughout the water column. Although oxygen transfer from certain methods may be significant, the greatest amount of oxygenation takes ...
