§ Captain Cunningham-Reidasked the Minister of Agriculture whether his attention has been drawn to a claim by the director of laboratories, United Dairies, Limited, that a solution of the problem of purifying milk-factory effluents has now been reached; whether the technical advisers of the Ministry have examined this claim; and, if so, what is the nature of their report?
§ Mr. W. S. MorrisonI understand that, as a result of investigations carried out under the direction of the Department of Scientific and Industrial Research, with the co-operation of the Rothamsted Experimental Station, 1383W two processes for treating milk-factory effluents have been evolved which are considered to be satisfactory. This work has been carried out with financial assistance from the industry, through the English and Scottish Milk Marketing Boards and with the aid of certain facilities provided by United Dairies, Limited. Full details of the investigations up to June last will be published shortly in the report of the Water Pollution Research Board of the Department of Scientific and Industrial Research.
