SINBIO works in close partnership with Dirk ESSER, associate consultant of SINBIO and director of SINT, and benefits from the results of research carried out by this company.  In fact, Dirk ESSER is one of the pioneers in the development of reed bed filters in France. Dirk ESSER plays a dual role as expert and conducts research and development for SINBIO, which allows our customers to access the latest innovations in constructed wetlands.

For example, our research has focused recently on: 

Ø  Improving the performance of reed bed filters plants in wastewater treatment (treatment of phosphorus and nitrogen); 

Ø  The use of reed bed filters for 

o   The treatment of sewage sludge and septage ;

o   The treatment of landfill leachate (ongoing research project).

o   The treatment of surface water runoff and CSO’s (ongoing research project).


SINBIO presented papers on the international conferences on urban drainage Novatech 2004, 2007 and 2010.

SINBIO is one of the three laureates of last year’s call for projects of the French Ministry of the Environment in the field of innovative demonstration projects in ecological engineering, in the frame of the French Biodiversity call for projects, for the construction of a demonstration constructed wetland for post-treatment of the Reims metropolitan waste water treatment plant (460 000 p.e.).  

In 2007 SINBIO acquired the operational consulting and engineering activity of SINT which resulted in the fusion of the teams, the means and the know-how of the SINT with that of SINBIO, in the areas which were part of her experience and recognized know-how, and in particular the design of reed bed filters for the treatment of various effluents. We thus can claim over 350 references in design and construction of reed bed filters.
