Arsenic in the Southwest

by TJ
Tonka Equipment Company

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
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.
