The world is in an escalating water crisis. Vital water sources are rapidly being both depleted and polluted by growing populations and their industrial and agricultural activities.

There is growing awareness of the problem, and of the need to dramatically step up wastewater recovery and to step down the discharge of toxic effluents.

However, the technology required to accomplish this is simply not available.

Wastewater, even in the most advanced markets, is still treated using basic technologies that were developed many decades or even centuries ago, and which are completely unsuitable for the very different environmental and operating conditions of today.

Purammon was founded by a group of advanced technologists and water specialists to address this urgent challenge. We are a technology company dedicated to applying the breakthroughs in materials science, nanotechnology, electronics, chemistry, and computing that have completely transformed other industries to the problem of water.

We focus on industrial wastewater, with a mission to create systems that on the one hand fit seamlessly into existing industrial processes, and on the other cost-effectively remove even the most difficult and pervasive pollutants.

Please be in touch to discuss your wastewater challenges.
