Abstract

In softening water it is first treated with an alkaline precipitating agent and then passed through a flaking chamber, containing numerous galvanic electrodes in the form of small separate irregularly-arranged bodies of opposite polarity in contact with one another, and through a filter in series with the flaking chamber, the rate of flow through the flaking chamber being such that there is no substantial deposition of precipitates therein. The electrodes may consist of small, open, hollow spiral bodies of metal or alloys. An alloy consisting of 85 to 90 per cent aluminium, 5 to 10 per cent copper, 1,5 to 4,5 per cent zinc and ,5 to 2,5 per cent lead is suitable, the preferred proportions being 88 per cent aluminium, 8 per cent copper, 2,5 per cent zinc and 1 per cent lead. Specifications 17372/94 and 16714/96, [both in Class 46], are referred to. The Specification as open to inspection under Sect. 91 comprises also the application of a flaking chamber as described to the promotion of precipitation in liquids other than water. This subject-matter does not appear in the Specification as accepted.ALSO:In softening water it is first treated with an alkaline precipitating agent and then passed through a flaking chamber, containing numerous galvanic electrodes in the form of small separate irregularly-arranged bodies of opposite polarity in contact with one another, and through a filter in series with the flaking chamber, the rate of flow through the flaking chamber being such that there is no substantial deposition of precipitates therein.
