Subsea Water Treatment Comes of Age

摘要

This subsea seawater-treatment system has undergone several phases of development since its inception in 2002. It works by extracting water from the seabed area (where there are inherent advantages such as space, stable temperatures, lower degree of bacterial concentration, and distance from platform discharges). A combination of residence time within a "still room," two steps of electrochemical disinfection, and chemical dosing are implemented to achieve disinfection and solids reduction.
