Abstract

A water treatment apparatus for use in for example a water injection system for an off-shore oil bearing formation to process sea water so that the chlorination of the sea water can be controlled. The apparatus comprises a membrane made up from first and second electrically conductive fluid permeable layers which are separated and electrically insulated from each other by a fluid permeable electrically insulating layer. An electrical potential is applied between the first and second layers, and sea water is pumped across the membrane. The chemical characteristics of the sea water passing through the membrane are monitored to provide a control signal for controlling the potential applied between the first and second layers, thereby enabling the control of for example the redox potential of the sea water emerging from the membrane. Furthermore, the membrane and electrically insulating layer provide coarse filtration of the sea water passing through the membrane.
