Product Info

VitaStim Rebuild is one of the most effective tools for quickly getting a wastewater treatment plant running again after an upset. This product is also beneficial to the process of starting up a new treatment plant. It contains a combination of specially selected bacteria and biostimulants to accomplish both tasks.

The bacteria in VitaStim Rebuild are selected for their ability to flocculate quickly, so they remain in the treatment plant instead of being washed out the back end. The biostimulants work to promote quick establishment of the new bacteria. When used in combination with a load of seed sludge, the biostimulants will boost the health of the sludge’s bacteria too.

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, D.O. 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.

  1. Josh L (CO)

    Quick-Zyme L, Smart BOD, and ReBuild have helped our plant recover and run great through start up and shock while jetting lines. Operation of two SBRs is needed to accommodate the volume of decant from the digester. We run on the low end of the F:M ratio and these products help with that also.

  2. Carl G.

    VitaStim Rebuild has been a godsend for us. It has really helped get the plant back to normal after a large dump from a local industry threw our plant into upset.
