Filter media for Arsenic removal from drinking water Approximately 300 million people consume water with Arsenic levels above the limit. Countries facing this problem include but are not limited to the USA, Canada, Japan, China, Bangladesh, Chile, Argentine , Australia, Greece, Hungary, Spain, Italy, Serbia, Poland, and Romania. Drinking water with high arsenic levels, leads to skin diseases and disorders in the blood vessels. Arsenic is currently removed by several processes, among which pre-oxidation of Arsenic is the one with the highest efficiency and the lowest cost.AquAsZero is the only water purification system with high adsorption capacity both for As(V) and for the 60 times more toxic As(III). AquAszero is 150% more efficient and requires 30% lower production cost than competition, while at the same time being the only solution that removes all types of arsenic.
