ABSTRACT:
A venting apparatus for a bubble contactor used to dissolve oxygen in water prior to introducing the water into a biological fluid bed reactor that, under aerobic conditions, removes potentially combustible contaminants from the water for removing fuel constituents from water. The venting apparatus includes a float-operated valve wherein the float senses the existence of a gas space in the upper part of the bubble contactor and is operable to open the valve to vent the gas space. Such a space is potentially capable of supporting a combustible mixture of oxygen and fuel constituents which could be ignited by a source, such as a static electric discharge. The valve remains closed under normal conditions when no significant gas space exists to prevent the needless waste of oxygen.
