We have received a request for feedback from any facilities or operators that have first hand experience of the impact from triclosan, tricloban or other antibacterial / biocide products on their systems. Please cite references if possible? Thank you.
Can anyone suggest papers or journals for the preparation of synthetic waste water which will simulate aeration tank effluent. We are working on a lab scale experiment to modify and observe the working of secondary clarifier , for the same we need synthetic wastewater recipe which will simulate the aeration tank effluent .

I personally prefer to use sludge age: Inventory in system/ inventory leaving system per day. If there is a high amount of inventory in the final clarifiers this should also be included in the system. If TSS lost to the effluent is significant this should be included in addition to the mass amount of sludge wasted from the system.
While using sludge age, also track and monitor other things such as SVI, F/M ratio, MLSS concentration, and effluent performance. Every couple sludge cycles or more often if there is a lot of variability, an advanced microscopic evaluation evaluating floc structure, filament abundance, protozoa and metazoan, type of filamentous etc. is useful to see which direction things are going, and identify the cause for any changes in the above parameters. Knowing what the plant looks like under the scope during “good conditions” is very useful because it provides a great baseline for troubleshooting when and if the time comes.
