The contamination of the world’s water resources is today a major issue for human health, destined to become of even more impact in the near future. The control of adverse effects to humans resulting from the assumption of arsenic, fluorine and vanadium present in drinking water has been achieved through the introduction of legal limits. In Italy this was accomplished in 2003 with the adoption of Legislative Decree no. 31/2001, which incorporated the Directive 98/83/EU, leading to the subsequent introduction of new more restrictive limits for the contents of arsenic from 50 µg/l to 10 µg/l, fluoride from 3 mg/l to 1,5 mg/l, Boron from 3 mg/l to 1mg/l.
The filtering media manufactured by the Gruppo Zilio guarantee compliance with the pollutants limits set by law. The operating costs have been greatly reduced because it is no longer necessary to replace the filtering material at the end of a cycle, but it is sufficient to regenerate the saturated material and to dispose of the solid waste of the exhausted filtrate.
The filtration solutions proposed by Gruppo Zilio S.p.A. include a wide range of sound technologies, tested and certified for the removal of arsenic, boron, caesium, chromium, fluorine, nickel, nitrate, sulphates, uranium and vanadium according to the principle of absorption or iron exchange.
Through project Regenera, which was supported by the European Union in the frame of the CIP Eco-innovation program and which has been selected by the European Union as one of the five success stories during the Eco Innovation day, Gruppo Zilio developed new processes for the removal of arsenic from drinking waters.
The plants built have capacities ranging from 1 l / s to 800 l / s with various types of intervention depending on the characteristics of the water to be treated and the existing treatment process.
