The Etschel Jet Master® - a high pressure impulse process (HPI-Process®) for water well rehabilitation and water well development

摘要

The technology to create high pressure impulses by means of high water pressure for loosening of deposits in water wells, which clog the filter screens, the gravel pack and the borehole wall is described in the DVGW (German Water Certification Authority) Handbook Section W 130 as a high pressure impulse process (HPI-Process®).
