Wastewater Unit Process Inspection: Rotating Biological Contactors Mobile App
A rotating biological contactor is a process used after primary treatment at a wastewater treatment plant.
How does it work?
After materials such as sand and grit are removed, the water will be collected in a vessel with biological mediums to remove pollutants. A series of closely spaced discs rotate above the surface of the wastewater. Since microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes place, which helps with the removal of solids from the water. The Wastewater Inspection Unit Process Rotating Biological Contactors app should be used during inspection to document the processes and operation of the rotating biological contactor. Details such as flow rate, biomass color, odor, aeration system, and mechanical drive maintenance should all be examined. Additionally, the processes should also be reviewed, including rotation time, speed, water temperature, and biomass thickness. Once the water is treated and systems for the filters reviewed, the water should be able to be discharged.
