Biosur Project

TITLE: Rotating Bioreactors for sustainable hydrogen Sulphide Removal (BIOSUR)
DURATION: July 2012 – December 2015
COORDINATOR: Consorzio Cuoiodepur Spa
BUDGET: 1.279.555,00 €

BIOSUR is a project co-financed by the European Commission under the LIFE+ Programme and involves the application of an innovative technology for the treatment and control of odorous emissions. The technical feasibility of the new technology will be demonstrated through the design, development and management of a RBBTF plant (Rotating Bed Biotrickling Filter) in a pre-industrial scale for the biological hydrogen sulphide (H2S) removal from gaseous effluents.

The innovative nature of the  RBBTF technology relies on the particular reactor design: a rotating bed bioreactor able to achieve high yields, unique and reminiscent in some ways the model of the typical reactor used in  tanning processes.

BIOSUR is the result of continuous research and experimental activities conducted in CER2CO (Centro Ricerca Reflui Conciari, tannery wastewater research centre), a joint lab born from the collaboration between the University of Florence and Consorzio Cuoiodepur Spa and from a long-term cooperation between the partners of the Project: Consorzio Cuoiodepur Spa, Italprogetti Engineering, Department of Civil and Environmental Engineering of the University of Florence and the Department of Biology of the University of Pisa.

The RBBTF will be installed at the Cuoiodepur WWTP in San Miniato, Pisa (Italy). The wastewater treatment plant treats the tannery effluent produced by more than 100 tanneries, operating mainly vegetable tanning, located in the Ponte a Egola District.

The main objectives of the BIOSUR project are:
  • Demonstrate the suitability of the new biotechnology for the removal of hydrogen sulphide from contaminated gas streams
  • Promote the new technology application in contexts other than tannery wastewaters treatment
  • Reduce the energy and chemicals consumption in hydrogen sulphide removal process
  • Minimize the whole tannery treatment train carbon footprint
