Abstract

1,258,080. Treating sewage. MACLEOD & MILLER (ENGS.) Ltd. 9 Jan., 1970 [31 Dec., 1968], No. 61808/68. Heading C1C. Sewage is aerated in a first chamber by means of a diffuser passed at constant rate to a second aeration chamber with a diffuser and then settled in a settling chamber. The treated liquid leaves the top of the settling chamber and sludge is recirculated to the first aeration chamber.
