Abstract

A settling tank for sewage contg. slowly sinking particles, with a bottom sludge outlet and inclined parallel plates between which the main upward flow takes place, has the effluent inlet adjacent to the bottom end of the plates, the outlet being near the top. This arrangement ensures that the entire flow passes along the plates, no bypassing.
