Arsenic continues to be a concern throughout the Southwest as many
communities have levels just above the maximum contaminant limit of 10
micrograms per liter (µg/L). These cities are looking at Tonka’s
co-precipitation filtration process paired with Simul-Wash™ for an efficient,
cost-effective way to remove arsenic, while conserving water and reducing
operating costs.
The process
The process
Iron is removed from water by oxidation, precipitation and
filtration, a process where Tonka has particular expertise and rich history.
Arsenic, in its oxidized state, will bind and coprecipitate with iron, which
can then be removed through conventional media filtration.
