Abstract
1458302 Waste water aeration STAMICARBON BV 25 Jan 1974 [29 Jan 1973] 03656/74 Heading B1C In a process and apparatus for the aeration of waste water containing suspended biologically active sludge, jets of recycled water are directed at an angle of not greater than 60 and at a velocity of from 3 to 12 metres/ second onto the surface of the waste water which is contained in a basin of circular, elliptical or regular polygonal horizontal crosssection, whereby aeration of the water and a rotary flow Vr is produced. In Fig. 1, two tubes 2, 3 having outflow openings 6 direct the jets of water onto the waste water in circular basin 1. Untreated water is introduced at 4 and treated water leaves at 5 while pump units 7 draw water from the basin and feed it to the tubes. In Fig. 2 the pump units include an impeller 11 driven by motor 13. Some of openings 6 may be blanked off to vary the output and the angle of the jets may be varied in an arrangement of relatively rotatable apertured pipes 100, 104 shown in Fig. 3. The output of the jets may be varied by changing the speed of motor 13.
