THE JOSAB ECOLOGICAL
WATER TREATMENT PLANT
IS VERSATILE AND RELIABLE

The ecological water treatment plant has few moving parts, the result is less wear and low maintenance costs. The highly efficient filter media, clinoptilolite facilitates compact units with very high capacity/volume ratio. Staff without any previous technical knowledge can be trained to operate the system within a day.

Josab’s ecological purification method is a mechanical water treatment in which particles and microorganisms larger than 1 micron are removed. Finally and as last step a UV filter disinfects the filtered water.

Natural and ecological

The system uses clinoptilolite which is a natural zeolite with exceptional adsorption capacity. Integrated into an appropriate technical unit it has proven superior capabilities in purifying contaminated water in emergency situations where the requirement for safe and sound drinking water is critical

Clinoptilolite is a natural zeolite consisting of silica and alumina tetrahedra. It occurs as weathering products of volcanic glass. It has a micro porous structure with a specific surface area as large as 500m2/g. It is a very good adsorbent for cations, notably ammonium, and non-charged but polar organic compounds.

It is used for the removal of heavy metals. The porous material offers

large adsorption surfaces for bacteria which are of particular value in emergency situations where the water is often polluted by pathogenic bacteria.
Josab has developed, designed and patented a modular mechanical water treatment concept that takes advantage of the clinoptilolite’s excellent properties such as adsorption, ion-exchange and micro-filtration.

Josab’s ecological purification method is a mechanical water treatment in which particles and microorganisms larger than 1 micron are removed. The clinoptilolite’s properties such as a large surface area, adsorption and ion exchange, is used in a pressurized tank.

A UV filter disinfects the filtered water and ends Josab’s ecological water purification method.

The treatment capacity ranges starts at 0.5 m3/h.

The UV-filter eliminates remains of, for example, heterotrophy, coliforms and Escherichia coli bacteria, as well as Giardia lamblia and Cryptosporidium parasites.

THE Most important
FACTOR is clean water!

The supply of good quality water is not only a basic necessity; it is also of paramount importance for the development of a society. Polluted water is a growing problem and the need for reliable cleaning processes is growing correspondingly. Josab’s Ecological water treatment plant is providing versatile mechanical water purification method and disinfection for a variety of applications in the most extreme conditions.

Superior adsorption and ION-EXCHANGE

  • Large active surface area: 200 – 500 m2/g
  • Uniform structure and large pore volume
  • Very fine pores: 0, 1 – 1, 0 Nanometre
  • The clinoptilolite’s composition of mezzo pores, macro pores gives a textural and morphological advantage.
  • Filters particles greater than 1 micron
  • Adsorb chemicals and petroleum products
  • Reduces heavy metals and ammonium and hydrogen compounds.
  • Removes bacteria: heterotrophy, coliforms, Escherichia coli, Giardia lamblia and Cryptosporidium parasites.

Clinoptilolite:
THE TECHNICAL SOLUTION

Josab’s ecological water treatment method uses the clinoptilolite’s properties, such as large surface area, adsorption and ion exchange. It has proven to be superior to other water purification methods. Clinoptilolite is a unique adsorbent with multiple functions. Well known are the removal of heavy metals and bacteria. It has been possible to contain clinoptilolite in portable and compact applications for emergency situations. The technical solution has been tested under harsh conditions. It has been successfully utilized in a number of emergency situations where the absence of safe and clean drinking water has been a major threat to public health.

Swift and easy to use

Depending on the operational requirements the units are either stationary framed, containerized, mounted onto trucks and trailers or portable. All units are designed for fast transportation to the point-of-need and for immediate performance on the emergency site.

With a production capacity of 0,5-135 m3/h the ecological water treatment plant is able to supply as many as 30 000 people with potable water from ground-, well-, and river- or lake-water sources.

Josab's containerized units are designed with a plug-in solution to

existing water works infrastructure and does not require any construction adaptations.

Josab's product range consists of stationary, containerized and mobile units with a capacity ranging from 0,5 m3/h to 135 m3/h, equal to the needs of clean water for 5 000-12 000 people for 8-10 h/day or up to
20 000-25 000 people for 20 h/day. That is corresponding to 4 litres of water per person and day, which is in compliance with the WHO's standards.

our patents

Patents; SE 9903704-6, RU 2242435, US 6,821,435 B1, ZL 00814211,4 and EU 1235750 etc. Josab’s ecological purification method is a mechanical water treatment in which particles and microorganisms larger than 1 micron are removed. The clinoptilolite’s properties such as a large surface area, adsorption and ion exchange, is used in a pressurized tank.
Finally and as last step a UV filter disinfects the filtered water. The highly effective filter material clinoptilolite is extracted from a mine in Hungary which is under the care, custody and control by Josab International AB. The patent is securing superior purification results since no other purification system can utilize the combined effect of Zeolite and UV-filters.
