About us

BlueGreen Water Technologies

BlueGreen Water Technologies was established in order to protect the world’s most precious and endangered resource – water. Most people take for granted that clean drinkable water will always be available when needed, but this is far from reality.  As aggressively toxic bacteria (cyanobacteria/algae) steadily poison the world’s water supplies, the substance that is most critical to human, animal, and plant life is diminishing fast. BlueGreen has stepped up to stem this fatal loss.

Harnessing technology to protect our waters

We use cutting-edge technologies to selectively target and eliminate harmful cyanobacteria/algae without harming other life forms or leaving any chemical trace in the water. Our treatments rehabilitate vast tracts of water within days, restoring environmental balance and biodiversity – improving health and economies, and impacting the lives of millions of people around the world.

Our water treatment formulations are market-approved and hard-tested in multiple markets, including Israel, the United States, China, and South Africa, and are certified internationally to meet the NSF/ANSI/CAN 60 standard for drinking water


Our data bank solves global water challenges

By deploying cutting-edge technologies and advanced analytics to track, trace, and analyze water bodies around the world, BlueGreen is also amassing a one-of-a-kind data bank and developing the expertise to resolve pervasive global water challenges – both those we know about today and those that will present in the future.

BlueGreen's driving force

The Leadership | HQ

BlueGreen was founded by seasoned scientists who have decades of experience working at the cutting-edge of environmental science and microbiological disciplines. Together, we make a formidable team with the scientific clout, passion, and drive to clean up the world’s water – one water body at a time.  Fuelled by our powerful R&D mechanism, in 10 short years we have registered 18 patents across the globe, are operational on every continent, and have carried out hundreds of applications on water bodies worldwide.
