One of the few things an operator can’t influence in their treatment plant is the influent. Greater use of biocides like peracetic acid (PAA) and Quaternary Ammonium compounds (quats) are making wastewater upset more common. The latest generation of biocides are more stable than ever, amplifying the problem.
Signs of Wastewater Upset:
- Ammonia spike
- Cloudy effluent
- MLSS color change
- Settling like a rock
In other cases, it might not be influent toxicity, but instead a disappearing mixed liquor. Slug loads of BOD, DO drops, and pH shifts are all potential reasons for an upset. It can also be as simple as getting “washed out” by a large rain event, or a large population of redworms (midge fly larvae) feeding on and destroying the bacteria population.
VitaStim Rebuild helps seed in heterotrophic floc-forming bacteria to rebuild a healthy mixed liquor that removes BOD and settles well. It can be used on its own, or in combination with fresh seed sludge.
To help fully solve issues related to wastewater upsets or with MLSS, VitaStim Rebuild works well with multiple companion products.
Nitrifying bacteria are usually the first casualties of upset and toxicity. VitaStim Dynamic Duo can help speed the recovery of nitrifying bacteria and lower ammonia in the process.
The main food source of red worms is MLSS, and they can decimate it in plants. AQUABACxt is a biological larvicide that can be used to get rid of the red worms without harmful chemicals.
CounterQuat is an innovation from the Aquafix Laboratories that strengthens your communities of beneficial bacteria to help prevent wastewater upsets from toxicity, like incoming cleaning products.
