The patented ALSI AutoWeir is designed to maximize floating solids concentration skimming in a tank or pit. The principle design innovation is that it operates based on the auto weir pump suction, as well as the level in the tank or pit.

As the liquid inside the box is drawn down, the float lowers, allowing skimming of the liquid surface, thereby increasing the efficiency of the downstream collection equipment.

  • Standard moving weirs automatically adjust +/- 9” to water level in tank
  • Stationary weirs automatically adjust +/- 1”
  • Stainless steel and PVC construction

The AutoWeir allows for adjustment up to two feet where the liquid level in the pit/tank has large variances. This adjustment can accomplished without user intervention.

Controls can be stand alone or integrated into your existing process controls.

Construction can be carbon steel, stainless steel or any other material deemed necessary for the application.
