Overview

What is HIX?

HIX (Hybrid Ion Exchange) is a patented resin platform engineered for the selective removal of inorganic contaminants from complex water sources.

The technology combines zirconium-based adsorption with ion-exchange functionality to deliver high selectivity, long operational life, and regenerability under field conditions.

HIX resins are designed for deployment in public and institutional drinking water systems where reliability, durability, and regulatory compliance are critical.

What HIX Removes

HIX resins selectively remove contaminants commonly encountered in challenging water matrices, including groundwater and other complex source waters.

As
Arsenic
F
Fluoride
P
Phosphate
U
Uranium
Pb
Lead

Certain process configurations also address sulfate and silica-related fouling challenges.

Why HIX is Different

Zirconium oxide nanoparticles provide high affinity for arsenic and fluoride relative to competing ions, enabling stable performance across variable source waters.

1

Selectivity

Patented HIX nanotech achieves 10x better arsenic and fluoride removal than conventional media. Maintains exceptional efficiency even in the presence of competing ions such as sulfate and phosphate—delivering consistent 99.9%+ contaminant removal across complex groundwater conditions.

2

Regenerability

HIX media is regenerated on-site, restoring full treatment capacity without replacement. This enables 5–10 year operational lifetimes and dramatically reduces costs compared to single-use filter systems.

3

Reduced Waste

Extended service life and regenerability reduce spent media disposal by 95% over the system lifecycle—lowering environmental impact and operational costs in resource-constrained environments.

The Three Rs

Drinkwell is built on circular economy principles—eliminating waste at every stage of the water treatment lifecycle.

Regenerate

HIX media is regenerated on-site every 6-12 months using a simple chemical process, restoring full treatment capacity. No replacement needed—just regenerate and continue operating.

100% Capacity Restored

Reuse

Our treatment media delivers 5–10 years of operational life through repeated regeneration cycles—eliminating the constant replacement cycle of conventional single-use filters.

5-10yr Media Lifespan

Recycle

Water jugs and bottles from our distribution network are collected, cleaned, and returned to service—closing the loop and keeping plastic out of the environment.

Built for Real-World Conditions

Locally Sourced Materials

HIX relies entirely on locally sourced, stable, and non-hazardous metals—reducing supply chain risk and import dependencies.

Simple Operation

Single-stage operation by local labor with low service requirements—no specialized technicians needed for daily operation.

End-to-End Integration

Vertically integrated design reduces reliance on third parties while passing cost savings directly to customers and communities.

Rural Grid-Ready

Energy-efficient process (6x lower than RO) suited for rural, outage-prone regions with unreliable power infrastructure.
