Backpackers and outdoors enthusiasts are likely familiar with Switerland’s Katadyn, which makes water filters, tablets, and water treatment products such as pumps. Established in 1926, the company is a global leader in portable water treatment, with its ceramic filters.

It also specializes in desalination, currently making various portable pumps aimed at the boating community, especially for emergency drinking needs, Katadyn’s Chairman Adrian Schmassmann told the Cleantech Group this week at the company's Zurich headquarters.
