Re: Rendering sea-water potable.
Reference:Letter of the Reich Leader SS
No. 39/4/44 secret of 17 January 1944.
To: Reich Leader SS and Chief of the German Police,
Personal Staff.

With reference to the interoffice conference between Oberstingenieur Christensen and Haupsturmfuehrer Engineer Dohle regarding the above-mentioned matter, it is announced that two processes have been worked out by the office to render sea-water potable:

1. The I. G. method, using mainly silver nitrate. For this process quite a large plant needs to be set up, which would require about 200 tons of iron and cost about 250,000 RM. The amount of the product needed by the Luftwaffe and Navy requires 2.5 to 3 tons of pure silver a month. Besides, the water which is rendered potable by this preparation has to be sucked through a filter in order to avoid absorption of precipitated chemicals. These facts make the application of this process practically impossible.
