Watts now offers its innovative OneFlow anti-scale system for home applications, in 8-, 12- and 16-gpm (30.28-, 45.42- and 60.56-L/m) models. OneFlow employs the template-assisted crystallization (TAC) physical water treatment technology. The system uses no salt, generates no wastewater and requires no backwashing, regeneration or electricity. Its compact design saves space compared to traditional water softeners. When water comes into contact with the media, calcium and magnesium minerals collect and combine, forming microscopic crystals. These inert crystals break away as they grow, remain suspended in the water and move harmlessly through plumbing, unable to form hard scale inside pipes or on appliances.
