The year 2009 is also a big success for PHT concerning their research work in innovative domains. The collaboration with Universities and engineering schools has become intense with the realization of two big projects in the waste water treatment, one in Switzerland with the support of the federal office for environment (with University laboratories from Switzerland and France), a second one in France where a PhD work begins this month (with the Universities of Savoie and Grenoble)

In addition two Master works have been carried out, one in the field of lakes (with the University of Lausanne), the second one concerns sedimentation and the distribution of the charges at the surfaces (with the School of Mines in Nantes). All this allows PHT to stay on the top of this technology and to develop the next application fields, the first results are already very promising.
