Our journey began in the Vatican 1983. Today, about 35 years later, we have come a come quite far on our mission – to improve people’s lives all over the world. Our technology is unique and make us a global developer within water purification, unlike any other.

Today pollutions of air, soil and water affect more and more people all over the world. Clean drinking water is a vital necessity to be able to live a decent life. The journey and mission for Josab to become a global actor that changes and improves the living conditions for people in regions without access to clean water, began 1983 in the Vatican.

Jan-Olov Sparrman, the founder of Josab, visited the Sistine Chapel in the Vatican during the 1980s for a restoration job. Valuable frescoes had been damaged by damp and water, and the underlying reason turned out to be the used building material. This material consisted of the Zeolit mineral, equipped with the ability to transport water. The discovery prompted Sparrman to start studying Zeolite minerals, and soon he found that they had fantastic abilities to absorb water and create ion-exchange.

These insights led to a new method which could be used to purify drinking water by eliminating bacteria. In 2001, the purification method was patented, and during the early 2000s, we developed and sold filter solutions to improve chlorine based purification methods. This was followed by Josab, with a project base in Ghana and Nigeria, in 2002 started delivering equipment for water purification. Today, the patented Zeolite mineral, Aqualite™, is mined in Josab’s self-owned mine, the Ratka mine in Hungary. The mine is located on land protected by UNESCO, and our operations are run according to thereby applicable regulations and precautionary demands.

Purifying polluted water to clean drinking water, that meet clients’ demands and the requirements of WHO-standards, is our core business. Our method is the only one of its kind and purifies polluted water without additives and chemicals. This makes us a global actor within water purification, unlike any other. In a time where environmental pollution and climate change is constantly making situations in regions of hardship even worse, ecological and sustainable business models are more coveted than ever.
