The history of JOSAB takes you from the Sixteenth Chapel in the Vatican in Rome, Italy, via swimming pools in Sweden to the famous wine districts of the Tokaji region in Hungary to end up with ecological water purification units for emergency situations and larger scale units for small to midsize villages and cities.

The history of JOSAB began 1983 in The Sixteenth Chapel in the Vatican, Rome.

The founder of JOSAB, Jan-Olov Sparrman, was asked to head a restoration work of some thousand year old buildings in the Vatican.

Some of the old frescoes (old wall paintings) in the Chapel were deteriorating due to humidity.
The reason for this was that many buildings were built with Tufo, a volcanic stone belonging to the family of zeolites.
This type of zeolites has astonishing capillary features of transporting water up to the height of six meters. Due to constructions with zeolite constantly kept the moist in the walls, the old frescoes deteriorated.
Thanks to a Polish patent the transportation of moist could be stopped at ground level and hence valuable frescoes could be saved and restored by experts.

During his three years in Italy Mr. Sparrman also studied other types of zeolite and found that there are many variants with different characteristics. Some of these zeolites had a structure that had adsorbing and ion-exchange capabilities. The different zeolites’ structure is dependent upon age and high water pressure after a volcanic outburst.

After returning back to Sweden Mr. Sparrman worked with cleaning water in swimming pools. He searched for a more efficient filter material than sand, and found that zeolite was an interesting alternative. This knowledge also became the link to Dr Janos Papp at Budapest University in Hungary.

During a number of years Dr Papp had studied zeolites and introduced Mr. Sparrman to Clinoptilolite, a special zeolite found in the Tokaji area in north eastern Hungary.
The specific features of Clinoptilolite brought Mr. Sparrman into the field of cleaning drinking water and with a focus on mobile units for catastrophe areas where there is an urgent need for clean water.
The first mobile unit was produced in 1990.

The idea of ecologically cleaning drinking water with a specific Clinoptilolite, where bacteria could be eliminated, was patented under the name
Aqualite™ .

JOSAB still sells the emergency units for catastrophe areas, but the main focus is to offer larger scale ecological drinking water purification units (ranging from 100-2700
per day). These units can be mounted in parallel for even larger capacity.

The first subsidiary was established in Hungary, where the mine and production unit to produce
Aqualite™ is located.

In 2013 Heilongjiang InterChina Watertreatment Co Ltd acquired shares in JOSAB and thus became the largest owner. The company operates, on the assignment of the Chinese government and private customers, water and wastewater treatment plants around China. The daily capacity is approximately 1.7 million ton. The company is listed on the Shanghai stock exchange (600187:SH) with a market cap of approximately 8.5 billion CNY.
