[ noun ] an apparatus for exposing something to the air (as sewage)
Used in print (Ross E. McKinney and Howard Edde, "Aerated...)Recent studies by Weston and Stack had indicated that a turbine aerator could be added to an oxidation pond to increase the rate of oxygen transfer . The pilot plant was equipped with a 3 - hp turbine aerator ( Figure 2 ) . The aerator had a variable speed drive to permit operation through a range of speeds . The raw sewage was introduced directly under the turbine aerator to insure maximum mixing of the raw sewage with the aeration tank contents . The periods of high effluent BOD occurred during cold periods when operational problems with the aerator resulted . |
