Water purification of arsenic

The problem of water purification of arsenic has recently become very topical because of the fact that requirements of WHO (World Health Organization) to content of arsenic in drinking water were drastically changed. Before permissible level of content of arsenic in water was 50 microgram per liter and now this figure is reduced to 10 microgram per liter. In this regard an enormous number of water resources in the world became over this limit. The problem is particularly acute for the USA, countries of the Central Asian region and the Far East, Japan, China, India, Bangladesh, Mexico, Spain. In some cases excess of arsenic concentration in drinking waters is so high, that there are already clinical features of mass poisoning of population.

Common water purification systems of arsenic are not enough effective and don’t enable to carry out the purification of water in small and separate systems.

The material PANION 140 is developed specially for household and local water purification systems of 3- and 5-valence arsenic. In comparison with existing sorbents the material PANION® secures faster purification of water due to its fiber structure, that makes possible to use it thin filtering layers, that in turn reduces by far dimensions of the filter. It is easy to use especially in household water purification systems.
