Abstract

Electrocoagulation may be used to reduce the concentration of zinc ions in produced water. For example, a method may induce producing a wellbore fluid from a subterranean formation, the wellbore fluid comprising hydrocarbons and water, the water having zinc ions dispersed therein at a concentration greater than about 1 ppm; separating the hydrocarbons from the water; and separating at least some of the zinc ions from the water via electrocoagulation to yield an effluent water and precipitated zinc salts.
