System and method for treating water

A system adapted to condition an initial water feed stream into a treated water stream, the initial water feed stream comprising at least one of a plurality of particles, a dissolved sulfate, a hardness, a plurality of dissolved solids, and a dissolved oxygen, the system comprising:

• a water treatment subsystem adapted to treat the initial water feed stream to remove the dissolved sulfate, the hardness, the plurality of dissolved solids, and/or the dissolved oxygen to form the treated water stream, wherein the water treatment subsystem comprises:
• a first oxygen removal unit comprising a membrane filter, wherein the initial water feed stream flows through the membrane filter and the first oxygen removal unit is adapted to treat the initial water feed stream to remove a first portion of the dissolved oxygen to form a first deoxygenated water stream;
• a hydrogen stream dissolved into the first deoxygenated water stream;
• a second oxygen removal unit comprising a vessel filled with a palladium-doped resin, wherein the second oxygen removal unit is adapted to treat the first deoxygenated water stream including the hydrogen stream dissolved therein to catalytically remove a second portion of the dissolved oxygen to form a second deoxygenated water stream;
• and,
• an oxygen scavenger feeder adapted to blend hydrazine and the second deoxygenated water stream.

• a first oxygen removal unit comprising a shell side, a tube side, and a membrane filter, the membrane filter having a first side adjacent to the shell side and a second side adjacent to the tube side, wherein the initial water feed stream flows through the shell side, the first oxygen removal unit is adapted to treat the initial water feed stream to remove a first portion of the dissolved oxygen to form a first deoxygenated water stream, and the first portion of the dissolved oxygen removed from the initial water feed stream is discharged from the tube side;
• a hydrogen stream dissolved into the first deoxygenated water stream;
• a second oxygen removal unit comprising a vessel filled with a palladium-doped resin, wherein the second oxygen removal unit is adapted to treat the first deoxygenated water stream having the hydrogen stream dissolved therein to catalytically remove a second portion of the dissolved oxygen to form a second deoxygenated water stream;
