Oil

Special Apparatus for Removing

There are two kinds of apparatus at present on the market for removing the oil from exhaust steam, the best known of which is the

Harris Anderson. The Harris Anderson apparatus for removing oil is very similar in every respect to that for softening water, except that the reagents employed are carbonate of soda and sulphate of alumina. The inventor of the Harris Anderson apparatus states that he has found, by careful microscopic examination of condensed water that has been subjected to the usual separation treatment by gravity, that globules of oil are floating about in the water, and that even the filtration by the very closest filtering material does not remove them. After oily water has been treated, the inventor finds that the globules

of oil are drawn together. The inventor claims that, by the addition of his reagents, and by the working of his process, the oil globules are caused to coalesce, and can then be dealt with by the filters in the ordinary way. The working of the apparatus is practically the same as that of the water softener.
