Abstract:
An apparatus for increasing the flow of a liquid in a conduit, comprising:a barrier for positioning in the conduit to prevent flow of at least some of the liquid past the barrier;a duct comprising a first end for positioning within a lower region of the conduit upstream of the barrier and a second end positioned above the first end at the downstream side of the barrier to direct flow of liquid through the duct from the lower region of the conduit upstream of the barrier to a higher region above the lower region downstream of the barrier; andan air pump for communicating with the duct to force air into the first end of the duct under sufficient pressure to mix with the liquid in the area of the first end of the duct and flow through the duct and out the second end of the duct to the downstream side of the barrier.
