Problems solved by technology

Due to various logistical limitations this water may not be readily and/or cost effectively disposed in injection wells.
In addition, the elevated levels of dissolved salts or total dissolved solids (TDS) in the water produce a potential for contamination of subsurface and surface waters from compromised storage systems.
Therefore certain restrictions through new and proposed regulations in many jurisdictions limit the means and/or increase to cost of storage of the water for reuse or awaiting disposal.
New regulations require secondary containment around the frac tanks and specially lined ponds and imp...

Embodiment Construction

[0049]Referring first to FIG. 1, the Applicants' apparatus for treating natural gas and oil well waste water is comprised of a pretreatment system for removal of dissolved and suspended organic matter and suspended inorganic matter in a manner similar to that disclosed in the aforementioned patent application Ser. No. 13 / 461,871 of Miller, et al., a cold soda lime softening subsystem 100, an ozone treatment subsystem 400, and a reverse osmosis system 500.

[0050]The pretreatment system is not shown in FIG. 1, but is provided between the wastewater lagoon 2 and the softening subsystem 100. The pretreatment system will now be described, as disclosed in patent application Ser. No. 13 / 461,871 of Miller, et al., as well as Patent Cooperation Treaty (PCT) Application No. PCT / US2012 / 036050, the disclosure of which is incorporated herein by reference. The remainder of the Applicants' methods and apparatus will then be described with reference to FIGS. 2-13.

[0051]The pretreatment system may fu...

Abstract

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 floes, filtration of waste salt floes, ozonation of the filtrate from the filtration, and reverse osmosis of the filtrate to produce a purified permeate.

Description

[0001]This application claims priority from United States Provisional Application for Patent No. 61 / 759,427, filed Feb. 1, 2013. This application is also related to the inventions disclosed in U.S. patent application Ser. No. 12 / 914,072 filed Oct. 28, 2010, which claims priority from United States Provisional Application for Patent No. 61 / 255,504, filed Oct. 28, 2009; and U.S. patent application Ser. No. 13 / 461,871 filed May 2, 2012, which claims priority from United States Provisional Application for Patent No. 61 / 481,370, filed May 2, 2011. The disclosures of all of these United States patent applications are incorporated herein by reference.TECHNICAL FIELD[0002]This invention relates to the removal of contaminants from waste water discharged at a gas wellhead, and more particularly to the removal of contaminants from water that is used during the process of drilling, hydraulic fracturing and / or cleaning a well bore, and then subsequently discharged from the wellhead.BACKGROUND AR...
