What is causing foaming, filaments and BOD violations in your wastewater treatment plant? Knowing your 30 minute settling may tell. The cause of different types of settling will vary and understanding  settling will give you more insight on the issues occurring in your plant. A 30 minutes settling test will point you in the right direction to diagnose these issues.

When your solids are not settling, this is due to filaments and dead bacteria. Your best option is to use our VitaStim Low F:M. Designed for low food to microorganism conditions, VitaStim Low F:M will allow for a robust biomass of flock-forming bacteria to form and prevent filamentous bulking and cloudy effluent by introducing biostimulants and micronutrients. Aquafix often prescribes this as a buffer for many situations including septicity, restarting tank/plant, and poor settling. For best result combine with Foam Buster.
