Research and Development of a New and Original Technology and Related Equipment for Pulse Electric Discharges in Water for the Construction and Water Industries

altProject: ТР-16002
Project Manager: Dr. Milenko B. Jevtić
Jaroslav Černi Institute for the Development of Water Resources

Based on in-depth studies of the theoretical background of mathematical physics and electrical engineering, the authors of this new technology researched the effects of pulse electric discharges in water and applied the outcomes of this research to benefit the construction and water industries. Namely, theoretical research revealed that pulse electric discharges in water create powerful electrohydrodynamic shock waves which can be exploited by these industries.

 

Project Goals

  • To conduct theoretical research and apply the new, original technology (PELHYDT);
  • To conceive, design and fabricate experimental PELHYDT units for laboratory tests addressing the rehabilitation of radial water well laterals, removal of sewer obstructions, and soil compaction;
  • To conduct the above laboratory tests and assess test results;
  • Based on test results and derived PELHYDT parameters, to design and develop three new solutions to be patented for application in practice;
  • To pave the way for the next goal: fabrication of industrial PELHYDT products, equipment and installations, hiring of additional staff, ensuring benefits for JCI and the country, and resolving a number of user problems applying the PELHYDT technology in Serbia and other countries.

Accomplishments

  • Over a two-year period, in-depth research was completed and three original experimental units were engineered and fully installed for tests under laboratory conditions:
  • The first experimental unit focused on the rehabilitation of radial water wells (Figure 1).
  • The second experimental unit was used to simulate sewer blockage removal (Figure 2).
  • The third experimental unit (Figs. 3 and 4) was used to compact soil and increase its load capacity under laboratory conditions.
