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. 

Congressman Visits Arsenic Removal Plant

by Rick Mann
Tonka Equipment Company

Congressman Fred Upton visited the new Iron and Arsenic Removal system serving the community of Mattawan, Michigan. Before the new system was installed, arsenic levels in the town’s three wells exceeded EPA’s requirements of 10 parts per billion (ppb).

Looking into all their options, they determined investing in a new treatment system was their only option. The arsenic was removed with iron co-precipitation absorption followed by filtration with Greensand Plus Media. Equipment  installation included four vertical pressure filters (VPF) to treat both the well on 25^th street and  the well on Main Street. This plant now provides clean drinking water to the small rural community of 3,000.
