Purammon was founded in late 2016 by a group of advanced technologists and environmental engineers with a simple mission: to bring the breakthroughs in materials science, nanotechnology, electronics, chemistry, and computing that have completely transformed other

industries to the critically important but still surprisingly low-tech world of wastewater treatment.

We installed our first commercial system (ammonia removal) in 2018, and since then have been providing solutions for the most complex wastewater challenges of some of the leading chemicals, fertilizers, power, and water companies in the world.

In 2020 we entered the energy world when we invented a technology that utilizes industrial wastewater to dramatically reduce the cost and freshwater impact of green-hydrogen production.  This technology is currently in validation in Israel’s leading environmental services facility and expected to enter industrial pilot in 2023.

We are extremely proud of the impact on environmental engineering that we have had in our short existance so far, and look forward to playing an increasingly meaningful role in the urgent efforts to clean and restore the ecosystems that we all rely on.
