摘要
A method for treating wastewater is disclosed. The method is useful in particular for treating wastewater that is generated from the process of drilling, hydraulic fracturing and/or cleaning a bore of an oil or natural gas well bore. The method may include performing cold lime softening of the wastewater to form waste salt flocs, filtration of waste salt flocs, ozonation of the filtrate from the filtration, and reverse osmosis of the filtrate to produce a purified permeate.
