HydroNovation is a leader in the development and application of HydroDI™ , a salt-free whole house water treatment system. HydroDI reduces contaminants and scale forming minerals for superior water quality in residential and commercial applications. HydroDI combines the benefits of a water softener and RO system in one system. The patented technology licensed from Siemens uses electricity to remove both cations and anions from the source water in a process called continuous electro-deionization. Unlike conventional water treatment approaches, this environmentally-friendly and energy efficient technology eliminates the need for salt or chemicals to treat water. The HydroDI system allows customers to save water and energy, improve water quality and reduce wastewater discharge.
