Abstract (en)
[origin: EP3263786A1] The pressure sewer systems comprised of the pressure main (1) and the house connecting pressure pipes (2) are dimensioned in the stage of designing to accommodate the nominal flow rate (Q n ) and the nominal pressure (P n ) of flowing wastewater. During common use, the instantaneous flow rate (Q i ) and instantaneous pressure (P i ) are several times lower, which results in the pressure main (1) fouling by waste. The method describes a temporary controlled change in the instantaneous pressure (P i ) and the instantaneous flow rate (Q i ) of wastewater up to the value approaching the nominal pressure (P n ) and nominal flow rate (Q n ) for the purpose of flushing the pressure main (1) of the pressure sewer system. The subject of the invention is also the system for generation the temporary controlled change in the instantaneous pressure (P i ) and the instantaneous flow rate (Q i ) of wastewater.
