ABSTRACT:
Biological treating systems include a treating tank for receiving wastewater to be treated, and a wastewater contacting unit mounted for reciprocating movement into and out of wastewater retained within the tank. Movement of the unit out of the wastewater exposes it to oxygen that is needed to maintain an aerobic environment for biolgical slimes, and movement of the unit into the wastewater permits these slimes to feed upon and metabolize pollutants therein. Preferably the systems include a plurality of wastewater contacting units positioned in pairs on opposite sides of axles and connected thereto. These axles are mounted for reciprocating movement, and a drive mechanism is provided to reciprocate the axles and the connected pairs of contacting units.
