QM Environmental International offers a wide range of solutions for optimizing biological wastewater treatment processes and odor control under the name MicroCat® bioaugmentation products, MicroCat®-SBP dosing technology and Dry Vapour Unit odour control technology.

MicroCat® products are microbial formulations which are applied to start-up, restore or enhance biological degradation processes. MicroCat products are mixtures of safe, natural ingredients. These include microorganisms (bacteria and fungi), enzymes, wetting agents, nutrients, adsorbents and buffers. MicroCat products are available in dry powder, liquid and solid form.

MicroCat products can be used in biological treatment systems ranging from activated sludge to trickling filters, from biodiscs to oxygen activated sludge and on wastes ranging from chlorinated aromatics to ammonia.

For large scale municipal sewage treatment plants MicroCat products are formulated to handle:

  • Odour and corrosion caused by hydrogen sulphide build-up
  • Non-chemical treatment of poor sludge settlement in secondary clarifiers
  • Problem foaming
  • Erratic BOD and COD reduction
  • Fat, oil and grease (FOG) build-up
  • Insufficient ammonia oxidation
  • Nearly any problem faced by municipal wastewater treatment professionals

MicroCat®-SBP – Bioaugmentation Made Easy!

Bacterial immobilization for your biological wastewater treatment

The SBP capsules are equipped with micro-membranes that work like an MBR (Membrane Bioreactor). The membranes keep the MicroCat® bacteria in the capsule, separated from the waste water.

Waste water and contaminants pass through the membranes so that the bacteria in the capsule are fed and can break down the contaminants.

The Dry Vapour Unit is an innovative odor neutralizing system which can be used to deodorize both indoor and outdoor areas experiencing nauseating odors and control off site odor emission.
For large scale municipal sewage treatment plants the Dry Vapour Unit is capable to handle:

  • Odors inside sludge dewatering buildings
  • Odors from sludge storage tanks
  • Perimeter odor control
  • Nearly any atmospheric odor problem faced by wastewater treatment professionals
