Method and device for separating suspended substances from liquids

Sepn. of suspended materials from fluids present in gas reactors, by flotation, comprises: (a) conveying the suspension, with a speed of up to 0.3 m/s, against the natural direction of bubbling, to introduce gas into the suspension; (b) withdrawing the suspension at the base of the gas reactor; and...

Beschreibung
Zusammenfassung:	Sepn. of suspended materials from fluids present in gas reactors, by flotation, comprises: (a) conveying the suspension, with a speed of up to 0.3 m/s, against the natural direction of bubbling, to introduce gas into the suspension; (b) withdrawing the suspension at the base of the gas reactor; and (c) carrying out flotation. Also claimed is the appts. for carrying out the above process, comprising a gas reactor (with a fluid height of 5.30 m) which is fitted with an exhaust stream reactor with a height:dia. ratio of greater than 1 but less than 30, (esp. 3).
