Awards and prizesEdit

The filter cartridge for table water using the patented Mg2+ technology received the National Award for Innovation for Upper Austria in 2011[3] The technology developed by BWT enriches the tap water with magnesium during the filtration process while removing any extraneous elements e.g. calcium, heavy metals and taste-inhibiting substances (e.g. chlorine).

In 2011 the Rondomat Duo S series of large water softeners (large water softeners are installed in buildings, commercial premises and industrial plants to prevent limescale deposits and the associated damage to the water pipe network and any appliances and systems connected to it) won the Austrian national design prize[4] in the Capital Goods category awarded by the Federal Ministry of the Economy Family and Youth (German: Bundesministerium für Wirtschaft, Familie und Jugend).

BWT’s building technology products for private households have been winners of the Plus X Award on two occasions. In 2012 the AQA perla[5] water softening system was voted 'Best Product of the Year 2013', and the E1 Single Lever filter[6] filter (a drinking water filter that prevents foreign particles and contaminants from entering the domestic system through the pipe network and damaging the installations) received the same accolade in 2013.
