Air entrainment (also known as entrainment technology or bioslurping) is the process of adding small air bubbles to the flow of water in a suction down tube. By adding these tiny bubbles to the down tube(stinger assembly) during a dual phase extraction event, these tiny bubbles actually creates an aerodynamic dragging action that lifts fluids up the slurping tube from depths that what would be unachievable with high vacuum alone. Typically, this allows extraction of the groundwater from depths over 100’.
