How to Determine the Ideal Return Sludge Flow Rate (RAS)


return activated sludgeIn order to determine and come up with the ideal sludge return flow rate or RAS, you will need an indicator that can tell you what is needed to be done. Basically the main consideration on what everyone is using is by referring to the Solids Level in the wastewater system. In order to control and adjust the solid level, there are 3 different approaches which you can rely on to provide you the necessary information and to serve as a guideline. Although most operators will argue that based on experience coupled with observations, all that should be sufficient to determine the return flow rate, but nevertheless you will still need something which you can quantify and measure.

Activated Sludge Process Control


In a wastewater treatment plant, it is important to control the Activated Sludge Process because this is the step whereby significant reduction in BOD and COD will take place. To ensure best performance, several control measures must be put in place such as ensuring that there is sufficient level of dissolved oxygen in the aeration tank and also adjusting the return and take off rate of activated sludge and waste sludge from the system.
