How it Works

Principle of Operation
A German engineer first developed the process of utilizing a suction control device to redirect the flow of water into a well in the 1950’s. In the late 1970’s, field tests conducted in California helped to confirm the operation principle of a suction control device. Since then, thousands of Aquastream Systems have been installed worldwide, resulting in billions of gallons of sandfree water.

When a pump suction is set above the formation, Aquastream found that water flow entering the well is much greater near the pump suction. Water inflow velocity diminishes rapidly with distance from the pump. This continues until the pump energy is dissipated. In a typical well, 100% of the water is pumped from 25 to 50 percent of the well. In other words, in a typical well, half or more of the well produces no water at all. This uneven energy distribution is the direct cause of sand pumping, mineral encrustation and other problems. Simply stated, high turbulent water velocities carry sand into the well. To overcome this problem, the Aquastream system evenly distributes the pump’s suction energy over the entire well, thereby eliminating areas of high water velocity. Energy is evenly dissipated, resulting in natural laminar flow throughout the well, yielding much higher outputs of sandfree water.

Typical well and Pump Operation without Aquastream Suction Control

  1. Pump suction is set above the top of the screen. This results in energy being released to the top of the screen first.
  2. Water flow accelerates to turbulent flow, often drawing in sand, particularly on start-up.
  3. Energy is pushed downward in the well until it is dissipated. Little or no flow occurs through the remaining well screen, regardless of depth of the well.

Typical Well and Pump Operation with Aquastream Suction Control

  1. Water velocity is greatly reduced at the top of the well where most sand pumping originates.
  2. Drawdown is reduced and turbulent flow is shifted to uniform, laminar flow. This increases water output.
  3. Energy is dissipated evenly over the well. Water is extracted more uniformly throughout the well. Well yield is increased, sandfree.
