What is a pneumatic ejector primarily used for?

A pneumatic ejector is primarily used for lift station pumping. In this context, pneumatic ejectors utilize compressed air to create a vacuum and transport wastewater or sewage from lower to higher elevations. This is particularly important in situations where gravitational flow is not feasible due to terrain or infrastructure constraints.

In lift stations, pneumatic ejectors are advantageous because they can effectively move wastewater up to treatment facilities or sewer lines located at higher elevations. This method of pumping is often preferred for its efficiency and ability to handle both solids and liquids without the need for traditional mechanical pumps.

Other options such as water filtration, chemical dosing, and general wastewater treatment are more focused on specific treatment processes or equipment types that do not utilize pneumatic technology in the same way as lift station pumping does. Consequently, these are not relevant applications for pneumatic ejectors.
