The project objective is to develop the design, production, and implementation of a decentralized water treatment system. In view of massive environmental challenges, water treatment solutions request flexibility, should be adaptive, and have effectiveness for a range of waste water types and volumes. HydroNET implements a modular systems approach to create a network of smaller, localized, interlinked and waste-specific purification plants by using space saving air flotation technology, and advanced IT solution for real-time, remote management.


The regulations about environment protection are becoming more and more stringent and the wastewater treatment plants should be rethought and improved to cope with them. Furthermore, is now more difficult to place space consuming traditional plants in crowded regions. In parallel the demand from emerging countries of effective and affordable wastewater treatment plants is constantly increasing. This requires the development of an innovative wastewater treatment plant that can be easily adaptable to many type of pollutants while reducing as much as possible the investment and operation costs (in order to be affordable to the developing countries communities).


The main objective of the HydroNET project is to develop the design, production, and implementation of an innovative decentralized water treatment system for deployment in developed as well as in emerging markets. For doing so the new wastewater treatment system should be:

  • flexible and easily adaptable;
  • scalable (in terms of wastewater volume)
  • effective for the treatment of a broad range of wastewater types;
  • affordable in terms of required space and investments as well as of operating costs.


Modularity and space saving

One of the particularity of the proposed technology is modularity, this allows on the one hand to reduce production costs shifting from the customized project paradigm to an assemble to order plant, where some basic easily customizable modules can be put together in function of the required treatments and the wastewater volume to be processed.

Prototype in Dongguan, China

With cooperation with Zhangcun Water treatment Plant—the biggest of those kind in the world, carrying treatment capacity of 2.6 million m3 per day—a HydroNET prototype machine was tested with channel water in Dongguan. In this case, the main objective is to remove TSS—Total Suspended Solids. The result was quite satisfactory as shown in the report by Centre Testing International (CTI)—a third-party quality inspection organization.
