Abstract

Sewage is purified by treating with powdered limestone and allowing solid matter to settle. The settled matter may be used as manure. Strongly alkaline sewage may be first treated with a cheap or waste acid. Specifications 11046/00 and 21297/02, [both in Class 111], are referred to. The Specification as open to inspection under Sect. 91 describes the use of other mineral carbonates, for example chalk, coral and dolomite, instead of limestone, and the addition to the carbonates of milk of lime or other alkali or alkaline-earth compounds or of acid calcium phosphate. This subject-matter does not appear in the Specification as accepted.
