Abstract
1346524 Treatment of polluted water S R KENNEDY 11 Oct 1972 [10 Dec 1971 14 Feb 1972] 46938/72 Heading C1C A treatment of polluted water comprises mixing the water with one or more of sulphuric acid, nitric acid and hydrochloric acid to lower the pH of the water to at least 2À5, maintaining this pH for a time sufficient to destroy bacteria present, then bringing the mixture into contact with an acid soluble form of iron for a time sufficient for the iron to react with part of the acid and then raising the pH of the mixture to 7 by the addition of an alkaline solution. During the contact with the acid soluble form of iron, at least one salt selected from the sulphates and nitrates of iron and aluminium, may be present. The mixture of acid and water is preferably contacted with at least 3À2 sq. ft. of iron per gallon per minute of acid and water mixture. Ammonium, sodium and potassium hydroxides are suitable alkaline solutions for use in the neutralization step.
