Abstract
Systems and methods for treating produced water and/or flowback water from fracking operations include: an oil water separator; a first filter downstream of the oil water separator; and an electrocoagulation unit downstream of the first filter. Systems and methods can be used for producing a concentrated brine for use in industrial applications and a separate stream of fresh water
Claims22
A system for treating produced water and/or flowback water from fracking operations, the system comprising:
- an oil water separator;
- a first filter downstream of the oil water separator;
- and
- an electrocoagulation unit downstream of the first filter.
A method of treating produced water and/or flowback water from fracking operations, the method comprising:
- separating oil from water being treated by using differences of specific gravity and then adding microbubbles of gas to the water being treated to lift material in the water being treated;
- applying electrocoagulation to the water being treated after separating oil from the water being treated;
- removing dissolved solids from the water being treated using ion exchange;
- and then
- removing dissolved salts from the water being treated using reverse osmosis.
A method of producing a concentrated brine for use in industrial applications, the method comprising:
- introducing produced water into an oil water separator;
- increasing oxygen levels in water being treated in the oil water separator;
- applying electrocoagulation to the water discharged from the oil water separator;
- concentrating dissolved salts in the water being treated using reverse osmosis to produce the concentrated brine;
- and
- collecting the concentrated brine for use in industrial applications.
