About biostream

biostream GmbH, based in Sehnde near Hanover, has been developing and distributing disinfectants based on chlorine dioxide (ClO₂) for drinking and process water since 2001. The products, including biostream® ZERO and biostream® asepticaPRO, disinfect water tanks, pipes, hoses, beverage dispensing systems, water dispensers, and the water lines of dental units and drinking water systems. The active ingredient chlorine dioxide is listed among the permitted treatment substances under § 20 of the Drinking Water Ordinance; the products comply with DIN 2001-2 and Article 95 (2) of the Biocidal Products Regulation (EU) No. 528/2012. A study by Leibniz University Hanover with 1,620 individual tests confirms a germ reduction of 99.9 % at a five-minute exposure time. Customers include Deutsche Bahn, Coca-Cola European Partners, the Bundeswehr, BRITA, Evonik, and the Berlin Water Works. The product range extends from 10-ml small containers to tank trucks, and is complemented by dosing calculators, dosing instructions, and telephone consultation.
