The Landia exhibit at WEFTEC included a video demonstration of its AeriGator chopper pump breaking through lift station crust.

The manufacturer reported that a wastewater treatment plant customer expects to save $10,000 per year on chemicals, plus $30,000 per year because vacuum trucks will no longer be needed to clean lift stations.

The AeriGator device is a low-cost, low-energy chopper pump with an ejector system. The pump uses no compressors, bottom-mounted diffusers or advanced controls. Air is automatically sucked into the ejector and then mixed with the wastewater. From there, it is pumped under pressure, into the lift station/tank. While reducing maintenance costs, the device frees operators from the unpleasant task of breaking clogs manually.

The chopper pump also macerates rags and debris while injecting air. An external knife system keeps the aerator from becoming clogged by contaminants in the wastewater. The company reports that every treatment plant that has taken an AeriGator unit on rental for a 90-day trial has purchased it within 28 days.
