Why to choose our technology?
Since, Our SBP Technology:
  • Expands hydraulic retention time in your bio reactor without the need to expand your bioreactor.
  • Secures low nitrogen concentration for your secondary effluent without the need to expand your de nitrification process.
  • Ensures your bio reactor will run smoothly even at high COD / BOD / Oil peaks incidents. 
  • Can be tailored to meet your specific requirements, such as, Oil, phenols and other compounds reduction.



The SBP process in domestic wastewater treatment is offered as an enhancing treatment, alongside the existing biomass that is naturally present in the bioreactor (mixed liquor). The two processes operate concurrently, such that the amount and variety of microorganisms that are active in the process increase significantly and lead to more effective decomposition of pollutants. The technology is integrated into the existing infrastructures at the wastewater treatment plant and its implementation does not require a significant investment. Read more about the technology.

Domestic treatment applications that can be achieved using the SBP technology 
  1. Treatment efficacy increases, without the need for significant infrastructure upgrading (up to 10% tons COD treatment increases per day).
  2. Selective contaminants removal (nitrates, phenols, fat and oils, mineral oils, etc.).
  3. Waste sludge (WAS) reduction of up to 20%. 
  4. Nitrate removal: inducing a de-nitrification process in the secondary clarifier without disturbing the phase separation process.
  5. Improvement of the effluent quality.
  6. Inducing and achieving long-term bio-process stabilization (reduction in the frequency and intensity of bio-process stress episodes as well as reduction in the biomass recovery time). 
  7. The annual treatment yield increases as a result of the improvements indicated in sections 1, 2 and 6.
Technology infrastructure implementation

The SBP capsules are placed in water-permeable cages made of polypropylene/PVC and stainless steel connectors. The perforated cage dimensions for SBP capsules insertion are 60*60*30 cm (l x h x d). The cage pores have a diameter of 0.8 cm. They can be submerged in liquid up to a depth 1-1.5 m below the water surface. These cages are inserted into the mixed liquor by manual cranes that are placed on the bridges of the aerobic cells (sketches of the cranes). There are two major types of introduction devices: On-bridge installation (see in this project) and bioreactor wall-attached installation (see in this project).

For a de-nitrification procedure, the perforated cages are positioned in the secondary clarifiers, 2 m below the water surface. Post de-nitrification is conducted within the perforated cages away from the settling sludge. The procedure therefore does NOT disturb the phase separation process.

SBP technology operation
Operation is simple and requires only periodical actions (once a month): 

  1. Pulling out the cages and gently washing them both inside (capsules) and outside (cage), in order to remove trapped sludge. 
  2. Adding new SBP capsules.
  3. Replacing the cages under the water: depth 1-1.5 m below the water surface.

Important note: The old SBP capsules eventually degrade into sugar. Thus they leave no environmental fingerprint. It is therefore not necessary to remove them from the wastewater or dispose of them.
