Abstract
Pumping system that uses compressed air to pump fluids continuously without inducing disturbances to the surrounding hydrologic regime. The suction source of the pumping system is the vacuum-drawing effect of a vortex created by a reflected air stream on an air reflector. The projected air stream on the air reflector is provided through the annular space between the inner and the outer tubing of a coaxial hose, and the reflected air stream carrying the effluent is discharging through the inner tubing of the coaxial hose. The flow of the projected and the reflected air streams is independently controlled using a coaxial hose splitter. Solid particles in the influent are filtered prior to entering the pumping system, and the effluent is separated upon discharge using separators.
