Our story began in the early 80s when Jan-Olov Sparrman traveled to Italy and discovered very special minerals named: zeolites. He found these natural materials with exceptional properties have been used since antiquity for water treatment. Jan-Olov Sparrman founded Josab in 1986 and created the most advanced water treatment process based on the use of a particular zeolite, located in Ratka in Hungary.

In the early 2000s, Josab acquired the Ratka mine in order to guarantee its supply and the constant quality of the filter media. Then, very quickly Josab became a major player in water treatment in crisis zones by providing hundreds of mobile units with the support of international organizations such as UNESCO, UNHCR and the Red Cross. We are proud to have been able to help populations in distress in Grozny, in Myanmar (Burma) and many other places in the world.

Josab expanded its international presence by establishing subsidiaries in Hungary and India and subsequently went public in 2013. In 2022, Josab Water Solutions began diversifying its technical expertise by venturing into wastewater treatment and embracing ultra-innovative and eco-friendly technologies.

This step is essential to become one of the major players worldwide in green solutions for treating water and waste.
