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 translation: 提供了一种在地下环境中生产净化水的方法，其中环境地下源水被引入并通过地下水处理系统的一个或多个超滤膜单元，由此产生基本上不含最大尺寸的固体颗粒的超滤液 大于0.1微米。 与至少一个超滤膜单元流体连通的电化学单元提供防污剂溶液。 在反冲洗循环期间，将富含超滤液的反洗液和至少一部分防污剂溶液输送至至少一个非生产超滤膜单元。 通过每天每平方英尺少于30加仑的每个超滤膜单元的源流体通量限制了反洗循环的需要。 反洗循环次数的减少增强了系统的自主性和使用寿命，并限制了维护和部件更换的干预需求。
