“我们在2012年完成了黄河水利枢纽改造工程。该项目用先进的22.0 MGD MBR设备取代了老化的14.0 MGD常规活性污泥设备。MBR设备包括用于固体分离的GE/Zenon浸没纤维膜。膜制造商要求至少2mm的屏蔽来保护0.04微米的膜。我们决定购买并安装Ovivo鼓屏幕，他们表现出色。我们有两个阶段的筛选。就在我们的头工程被JWC研磨机保护后，进水被泵到我们的初步建筑和我们的5毫米圆筒筛。我们有一个任务，一个备用每个额定为64 MGD。5毫米桶在2009年12月投入使用。在此期间，我们更换了密封桶两次和一个驱动单元变速箱。 After preliminary screening, grit removal, and primary clarifiers we protect our Biological Basins and Membrane Tanks with two 2 mm Drums. One duty, one standby each rated at 32 MGD commissioned in April 2010. Other than routine PM’s we have not performed any corrective maintenance on the 2 mm Screen. Our average daily flow is 14.0 MGD and we remove approximately 12 to 15 tons of screenings a week. We quarterly drain and clean a Primary Clarifier, Annually clean a Bio-Basin and monthly inspect our MBR Cassettes and we have no evidence of screenings, rags or hair past our screening processes. Our MBR Facility is operating as well as (better than) any in the world and I attribute that a lot to the effectiveness of our Ovivo Drum Screens that protect our biological process and membrane solids separation.”
