Austrian water engineering with proprietary magnesium enrichment. Combines multi-stage filtration with Mg²⁺ exchange technology for mineral-optimised output.
BWT (Best Water Technology) is the largest European water technology company, headquartered in Austria. The AQA Smart is their flagship residential under-sink system and brings a feature unique in the residential filtration market: magnesium enrichment technology.
Standard filtration systems remove contaminants. The BWT AQA Smart does that — but its ion exchange stage also enriches the filtered water with magnesium ions, which BWT positions as a health benefit (magnesium is a common dietary deficiency in Southern European populations). The cartridge contains a food-grade magnesium bed through which water passes after the carbon stage.
Filtration performance covers chlorine, chloramines, limescale, heavy metals, and sediment via multi-stage carbon block and ion exchange. It is not an RO system and does not remove PFAS to the same degree as RO or NSF-401 carbon systems. For Mediterranean households where the primary concern is taste, limescale, and general chemical reduction rather than deep contaminant removal, the BWT AQA Smart is a premium European-engineered choice.
The system uses a smart cartridge with an RFID chip that communicates remaining filter life to a companion app — a genuinely useful feature that prevents the "forgot to change the filter" situation common with most systems. Available through major European retailers and BWT's direct channels.

Positive stories about rivers, restoration, and clean water across the Mediterranean and beyond.
The Council of the EU officially adopted the European Water Resilience Strategy, committing to restore rivers, lakes, and wetlands and guaranteeing clean, affordable water for all Europeans by addressing pollution at the source.
wareg.org ↗Eight obsolete river barriers were removed at Plitvice Lakes National Park — the first dam removals in Croatia's history — reconnecting 7.6 km of river and restoring habitat for the endangered Danube trout.
damremoval.eu ↗A 30-metre dam on the Liri River was dismantled by Rewilding Apennines, freeing over 11 km of waterway. Thousands of juvenile Mediterranean trout were released to repopulate the restored river.
rewildingeurope.com ↗MedINA published Greece's first practical roadmap for removing river barriers — a critical step that unlocks funding and policy support for dam removal across the Mediterranean region.
med-ina.org ↗Authorities in Spain's Basque Country began breaking down a 43-metre-high dam on the Leitzaran River — one of the largest obsolete dams in Europe — letting the river flow freely for the first time in decades. The EU-backed LIFE Kantauribai project will reconnect fish habitats and restore the ecosystem.
euroweeklynews.com ↗A landmark report found 23 countries removed river barriers in 2024 — up 11% year-on-year. Spain dismantled 96 dams, France 128, Finland 138, bringing the EU closer to its goal of 25,000km of free-flowing rivers by 2030.
theguardian.com ↗The European Commission adopted the European Water Resilience Strategy in June 2025, with the European Investment Bank pledging €15 billion (2025–2027) for water restoration. The strategy sets a path to clean, affordable water for all Europeans by 2050.
