Rotation studies are used to analyze the operational performance, efficiency, and maintenance needs of the rotating screen used in water intake systems, especially those in power plants, water treatment facilities, and industrial cooling systems. These studies help ensure that the traveling water screens continue to operate efficiently and effectively, minimizing the risk of system failure and optimizing the maintenance schedule.

 

In June of 2024, the Flow Labs team began conducting a rotation study to determine the effectiveness of five traveling water screens, placed by our client, Consolidated Edison, which filter debris and protect larger fish in the source water.  

 

Under the current State Pollutant Discharge Elimination System (SPDES) permit, the facility is required to operate these screens continuously. Throughout the study, we collected data to evaluate whether intermittent operation could effectively filter debris while still maintaining adequate fish protection.  The findings will help determine if a permit modification is feasible. If approved, this change could lead to more sustainable and cost-effective operations for our client. 

The study officially concluded late last month, and we greatly look forward to seeing the results.
