Comparison of startup and anaerobic wastewater treatment in UASB, hybrid and baffled reactorAbstractAn experimental study was carried out to compare the performance of selected anaerobic high rate reactors operated simultaneously at 37 °C. The three reactors,namely up¯ow anaerobic sludge bed reactor (UASB), hybrid of UASB reactor and anaerobic ®lter (anaerobic hybrid reactor ± AHR) and anaerobic baf¯edreactor (ABR), were inoculated with the anaerobic
INVESTIGATION OF SUBMERGED INLETS TO DEEP RECTANGULAR SLUICESN. P. Rozanov, N. Ya. Konakhovich,and L. N. Orlova UDC 532.522.001.5The form of the inlet to deep sluices should be selected to meet the following conditions: 1) cavitation does not occur; 2) on changing to a pressure flow from a free flow or vice versa unfavorable transitional regimes do not arise in the sluice, and the pressure remains stable; 3) the dimensions of the inlet bellmouth be as small and its outli
