Abstract: A method of producing purified water in a subsurface environment is provided in which ambient subsurface source water is introduced into and through one or more ultrafiltration membrane units of a subsurface water treatment system and producing thereby an ultrafiltrate substantially free of solid particulates having a largest dimension greater than 0.1 microns. An electrochemical unit in fluid communication with at least one ultrafiltration membrane unit provides an antifoulant solution. An ultrafiltrate-rich backwash fluid and at least a portion of the antifoulant solution are delivered to at least one non-producing ultrafiltration membrane unit during a backwash cycle. A flux of source fluid through each of the ultrafiltration membrane units of less than thirty gallons per square foot per day limits the need for backwash cycles. A reduction in the number of backwash cycles enhances system autonomy and useful life, and limits the need for intervention for maintenance and component replacement.

Abstract: A subsurface water treatment system is provided which may be used to produce purified water using ambient subsurface water as a source fluid. The system includes one or more ultrafiltration membrane units which use ambient water as the source fluid and to produce therefrom an ultrafiltrate substantially free of solid particulates having a largest dimension greater than 0.1 microns. An electrochemical unit provides an antifoulant solution comprising hypohalous acid species. A backwash unit allows periodic cleaning and defouling of a non-producing ultrafiltration membrane unit. The system may also include a nanofiltration unit and a reverse osmosis membrane unit which may be used to produce purified water having any of a wide range desired total dissolved solids content. The novel systems and methods described may be used to stimulate the production of hydrocarbon fluids from a hydrocarbon reservoir.
