Record 2 2011-06-03

English

Subject field(s)
  • Equipment and Tools (Water Supply)
  • Wastewater Treatment
DEF

A two-story combination sewage sedimentation and sludge digestion facility, usually constructed of reinforced concrete. The top story is the sedimentation compartment, and the bottom story is the sludge digestion compartment. The incoming sewage flows slowly and continuously through the settling compartment ... and settleable solids carried by the liquid drop down through a trapped slot and form the sludge deposit in the sludge digestion compartment below.

CONT

The Imhoff septic tank, an improvement over the ordinary septic tank, is still used in the United States; it is a two-story structure with the upper compartment used for settling the sewage, the lower one for the anaerobic disintegration of sludge. A sloping floor enables solid material to slide to the lower compartment, where, since the sludge is separated from the material in the sedimentation compartment, the action is more rapid.

OBS

This two-storied wastewater treatment tank was originally patented by Karl Imhoff.
