BWT Water Treatment

BWT (Best Water Technology) are our water filtration partners of choice. We offer their complete range of water filtration systems from basic cartridge filters for limescale protection and flavour retention, to advanced reverse osmosis solutions.

Water treatment for coffee is designed to protect equipment from limescale and corrosion damage while retaining desired mineral content for optimal flavour. 

Cartridge solutions come with universal filter heads for all BWT products, designed to be reused for a hassle-free screw-on cartridge replacement. Volcano Coffee Works will advise on the correct cartridge to best suit the raw water specifications in any application.

BWT bestmax Premium and BestMin cartridges combine cutting edge mineral resins to ensure your water will never leave coffee tasting thin or aggressive.
