Test on italian wastewater treatment plant

Improve the biological efficiency of the Sludge with BioBANG

BioBANG technology also lands in wastewater treatment plants to break up definitively the sludge, increase the efficiency of biological processes and optimize disposal costs..

On February 12, our technicians of the mobile unit performed a test in Rome on a wastewater treatment plant owned by “Acea”, a multiservice company active in the management and development of networks and services in the water, energy and the environment.

Acea managers were looking for a treatment technology that guaranteed them to increase the breakdown of organic particles, improve homogenization and reduce the viscosity of the sludge to optimize hydraulic management and the yield of the anaerobic digestion line and to maximize the efficiency of the dehydration process and reducing the volume of sludge to be disposed of; for this reason they turned to BioBANG.

The test was performed on 3 Sludge’s samples taken from different points of the plant line: 1. Sludge recirculated by the digester; 2. Sludge after thickener entering digesters; 3. Separate sludge after spinning. In the first 2 cases, the sludge had a dry matter content of about 3.5%, while in the last case the sludge had a dry matter concentration of about 25% and it showed up in a semi-dry form.

Acea’s technicians were amazed by the results brought by cavitation on both 3 sludge samples and the important benefits they can draw to increase the efficiency of the plant.

For recirculated sludge and sludge from the thickener, BioBANG will allow to:

  • break up all the organic particles contained in the sludge to improve the yield of the anaerobic digestion line and maximize the efficiency of the dehydration process.
  • reduce the viscosity of the sludge in digesters by over 50% to improve their hydraulic management and reduce the energy consumption of mixers and recirculation / pumping systems.
  • Transfer heat directly to the sludge and bring it instantly to temperature, optimizing the energy savings of the heat exchangers.

For centrifuged sludge, BioBANG allows to transform it from semi-dry form to pumpable form, maintaining the same dry matter content, and to recirculate it again at the top of the treatment process, obtaining the same advantages described previously and completely eliminating the biology of the sludge to obtain at the end of the cycle, a smaller quantity of sludge to be disposed of, optimizing disposal costs.

Once again BioBANG proves to be effective also to make wastewater treatment plants more efficient.
