Abstract: A water motor which includes a tubular tipping lever arm open on both ends and a central water fill port, and a central fulcrum pivotally supporting the tipping lever arm for seesaw tipping thereabout. Temporary containment vessels are provided on opposite ends of a work lever arm and positioned under each open end of the tipping lever arm to receive water flowing from a respective one of the open ends of the tipping lever arm. A drain valve is provided in each container for respectively draining water from the containers and the drain valves are respectively opened when a respective one of the containers is in a minimum height position. A directional flow control lever depends downwardly from the tipping lever arm and protrudes between spaced lever control stops which cyclically engage and reverse the seesaw tipping of the tipping lever arm and also provides resultant draining of a respective of the containers with the push rod engagement force of the lever control stops.

Abstract: An in-line system is provided for treating acid mine drainage which basically comprises the combination of a jet pump (or pumps) and a static mixer. The jet pump entrains air into the acid waste water using a Venturi effect so as to provide aeration of the waste water while further aeration is provided by the helical vanes of the static mixer. A neutralizing agent is injected into the suction chamber of the jet pump and the static mixer is formed by plural sections offset by 90 degrees.
