A complete WW package plant would be a system that included the screening or WW solids grinding, activated sludge tanks, clarifier, filtration w/BW pumping, RAS Pumping, WAS Pumping, Aerobic Digestion, and blowers.  Most systems are round outer tanks with compartments arranged in various configurations.  Typically the clarifier is in the middle.  Air lift pumps are used for RAS and WAS pumping.

Dear Dr

In my idea the full scale designing of wastewater treatment plant can be applied instead of complete package wastewater treatment plant  or they are synonym.
