Zusammenfassung: | A liquid treatment apparatus for removing potentially combustible substances from water includes a biological fluid bed reactor (16) that is supplied by a first conduit with contaminated water (14) and that treats this water, under aerobic conditions, before discharging it as treated effluent (22) containing a significantly reduced concentration of contaminants. The liquid treatment apparatus also includes a gas dissolution apparatus (38) for providing dissolved oxygen to the contaminated water flowing through the first conduit to sustain biological action in the reactor. The gas dissolution apparatus includes an oxygenator (44) including a pressurized bubble contactor (46) disposed in a recycle conduit connected between the outlet (22) of the reactor (16) and the first conduit (14). |
