Hydropuls is a pulse process for the purpose of increasing or restoring the productivity of production wells and development wells as well as the restoration of the functional capability of groundwater measuring points.
The mode of action is that pressure pulse sequences are created by pulsing inputs of gas or water portions under high pressure using a pulse generator that is inserted in the well attached to the pressure hose. The pulse generator is provided with a valve system that is able to release the energy that is accumulated in the generator in the form of high-tension gas or water within a very short switching time (milliseconds) by opening large cross sections. This creates hydraulic shock waves. At the same time, a cavitation effect is caused by the sudden volume change leading to the formation of a “vacuum bubble” that subsequently collapses and thus creates a hydraulic “suction wave”.
According to the DVGW leaflet W 130, this process is an approved process.
