ABSTRACT:
A method of operating a sequencing batch reactor having a cycle consisting of FILL, REACT, SETTLE and DRAW periods and optionally an IDLE period, wherein supply of feed to the sequencing batch reactor comprises distributing the feed into settled sludge in the bottom part of the reactor. Also provided is a method of operating a sequencing batch reactor having the foregoing cycle, wherein the FILL and REACT periods include at least one non-mixed period.
