Bacterial immobilization for your biological wastewater treatment

QM-SBP

QM-SBP technology is the next step in bioaugmentation. The definition of Bio(logical)augmentation is the addition of archaea or bacteria cultures that are needed to accelerate the degradation rate of a contaminant. QM-SBP technology makes bioaugmentation simple, labor-saving and effective.

Small Bioreactor Platform

The QM-SBP technology uses capsules equipped with micro-membranes that function as a Membrane Bioreactor (MBR). The capsules are supplied with a small amount of MicroCat^® bacteria and the membranes keep the bacteria in the capsule, while wastewater with dissolved contamination can flow into the capsules unhindered. In the capsules, the bacteria grow on the incoming waste materials and multiply until the capsule is full. The capsules are made of biodegradable organic material and do not burden the environment. The capsules have an average lifespan of 2 months.

The SBP capsules form a small bioreactor (Small Bioreactor Platform). Where daily bioaugmentation doses are applied in sewage and industrial wastewater treatment plants, the SBP capsules can be used as an alternative. This reduces the daily labor effort and the amount of bioaugmentation product that is dosed into the treatment plant per year. By placing the SBP capsules in a cage and hanging this cage in the aeration basin of the wastewater treatment plant, they do not flow out of the treatment plant but remain there until the capsule breaks open. The bacteria that have multiplied in the capsule are then released into the aeration basin and become part of the biomass in the aeration tank.

In principle, any dried MicroCat^® bioaugmentation product can be used in the SBP capsules. This allows a wide range of wastewater treatment plants to be equipped with the QM-SBP technology. All that is needed are cages to hold the capsules in the treatment and levers to lower the cages into the water and raise them again when capsules need to be added.

How are SBP capsules used?

Based on your wastewater analyses and flow rate, QM experts will determine which MicroCat^® formulation goes into the SBP capsules and how many capsules are needed per month.

The SBP capsules are suspended in a perforated cage in the wastewater in the aeration tank. The cage is moved in and out of the wastewater by means of a hoist mechanism.

The SBP capsules have a shelf life of 2 months. The SBP capsules are made of biodegradable organic material that breaks down into sugars. SBP capsules do not burden the environment.

How do SBP capsules work?

In the capsules, the MicroCat^® bacteria are safe from protozoa (bacteria-eating higher life forms that live in the sludge), dilution and leaching.
Contaminants always flow into the SBP capsule as long as the bacterial population in the capsule breaks down these contaminants (diffusion).
A biofilm will not clog the membrane because it is equipped with a strong negative charge that repels the biofilm.

Advantages

Growing, separating and recirculating biomass is unnecessary	Rapid recovery after toxic shock event
Reduction of CAPEX up to 70% and OPEX up to 50% (reduces costs for daily bioaugmentation doses)	Easy to use, no need professional external manpower to operate it
Starts working immediately. No need for inoculum and/or long adaptation period.	Suitable for all MicroCat^® powder products
The most environmentally friendly and economically viable approach for enhanced degradation of pollutants
