Katadyn, probably the world market leader in the sector of portable water purification solutions with a market share higher than 50 percent, continues to diversify its product range. It has acquired a majority stake in the Swiss and German operations of Aquafides, a manufacturer of industrial water purifying equipment. The Swiss already were in that type of business until 1999 when it teamed up with the German Wedeco company to get rid of that investment through an IPO. According to Katadyn information, the new products developed by Aquafides (founded in 2007) made sense to the company to invest again in that sector. Aquafides is basically run by former executives of Wedeco.
