Jet aerators
Encyclopedia
A jet aerator is an aspirating device, which is used to aerate liquid such as water, sewage
, sludge, manure, leachate
, etc. The jet aerator works by the principle of venturi effect
and the liquid is typically supplied by a centrifugal chopper pump. The main advantage of using a chopper pump is that it prevents clogging of the pump and the venturi/nozzle, as all the solids and stringy materials are macerated by the chopping system.
Sewage
Sewage is water-carried waste, in solution or suspension, that is intended to be removed from a community. Also known as wastewater, it is more than 99% water and is characterized by volume or rate of flow, physical condition, chemical constituents and the bacteriological organisms that it contains...
