Napowietrzanie z użyciem mieszadła ze zwiniętymi śrubowo łopatkami wstęgowymi

Studies on aeration process of medium in a tank equipped with the impeller with rotary ribbon paddles were discussed. Measurements of mixing time and power consumption enabled one to determine the effect of such essential parameters as the rotational impeller frequency, number of paddles and gas flow rate on mixing process. The efficiency of the impeller tested was also compared with flat-blade- disk turbine one.
