ElectroChemical Arsenic Remediation (ECAR)

Gadgil Laboratory, University of California Berkeley

This product utilizes an electrolysis process to absorb and reduce arsenic concentration in water.

Product description Brand name and product description

ECAR (ElectroChemical Arsenic Remediation) works using low-voltage electricity to dissolve an iron electrode, creating iron oxide (rust). The rust particles adsorb arsenic, creating larger particles, which are then filtered out of solution. The process converts arsenite into arsenate, a less toxic compound that can be more efficiently removed from water.
