Hydrus Technology is privately held Australian company that is leading a global paradigm shift in water and wastewater treatment. This shift started with the development of our intellectual property for Advanced ElectroChemical and Catalytically Enhanced Oxidation. Those technologies are now the driving force behind HTX closed-loop water recycling service.

These technologies enable a chemical-free process for turning contaminated water and wastewater into water ready for reuse or release into the environment—ending the cycle of fresh water to wastewater so common in industrial water usage. Specifically, the outflow of the HTX service meets typical Environmental Protection Agency (EPA) standards or customized water quality standards.

Hydrus has raised the bar for the removal of harmful contaminants, such as hydrocarbons, and extraction of valuable minerals and is committed to the cost effective and high-quality treatment of water and wastewater.
