Process and apparatus for the jet cleaning of a stormwater tank

摘要

Process for the jet cleaning of a stormwater tank by means of at least one jet pipe. Up until now, the jet pipe was arranged such that it could not move and generated a circulating waste-water flow. Deposits on the bottom of the tank were removed often only to an unsatisfactory degree. The jet pipes, or at least one jet pipe, are displaced such that, consequently, any deposits located on the bottom of the stormwater tank are channelled away, at least to a considerably greater extent than was the case without this displacement of the jet, out of the stormwater tank along with the wastewater flowing out of the latter.
