ABSTRACT:
An improved aerobic waste treatment package which both simplifies maintenance of the system and increases the interval between necessary maintenance through the use of a removable surge bowl which forms part of a centrally disposed, large capacity, surge chamber positioned above the waste treatment holding tank. The package also simplifies maintenance by permitting removal of the surge bowl without disconnecting the electrical connections to the package and through the use of a simplified system for suspending porous filter bags from a hanger plate extending across the top of the holding tank.
