Every stage below is designed, built and commissioned by EcoTech — shown here at our demonstration plant.
Disinfects incoming flow
Contact time & buffering
Membrane separation
Sediment pre-filtration
Bind arsenic & heavy metals
Final polishing stage
Our patented iron-hydroxide adsorption media outperforms conventional treatment — binding heavy metals and removing them from the water cycle permanently.
No precipitants, no secondary filtration. Our media binds heavy metals for good, so the waste requiring disposal is far lower.
A science pioneered by Michael Faraday and Joseph Henry, to revolutionize water treatment.
The result? Cleaner, safer, and sustainable water treatment — without chemicals, preserving both health and the environment.
From treatment media to engineering and construction, we deliver alongside trusted global and local partners.
