The method includes receiv­ ing a feed stream including at least one substance dissolved in a water phase, and processing the feed, water stream in a plurality of stages arranged in operation from a lowest temperature and pressure to a highest temperature and pressure, to produce the treated water stream and concentrated a stream. Each stage includes vessel, heat exchanger, an evaporator, a a and a condenser. Each evap - orator is configured to evaporate an amount of water using one of direct heat or indirect heat. Each condenser configured is to con - dense at least a portion of steam generated by a successive stage. In accordance with various embodiments, the plurality of stages is arranged in series. In other embodiments, the plurality of stages is arranged in parallel.
