    Abstract: Water treatment systems and associated methods are generally described. Certain embodiments of the water treatment systems and methods described herein may be used to treat water comprising one or more contaminants (e.g., oil, grease, suspended solids, scale-forming ions, volatile organic material) to remove at least a portion of the one or more contaminants. In some embodiments, at least a portion of the treated water may be used directly in certain applications (e.g., oil and/or gas extraction processes). In some embodiments, at least a portion of the treated water may undergo desalination to produce substantially pure water and/or concentrated brine.

    Abstract: Systems and methods related to desalination systems are described herein. According to some embodiments, the desalination systems are transiently operated and/or configured to facilitate transient operation. In some embodiments, a liquid stream comprising water and at least one dissolved salt is circulated through a fluidic circuit comprising a desalination system. In some embodiments, a portion of the desalination system (e.g., a humidifier) is configured to remove at least a portion of the water from the liquid stream to produce a concentrated brine stream enriched in the dissolved salt. In certain cases, the concentrated brine stream is recirculated through the fluidic circuit until the concentrated brine stream reaches a relatively high density (e.g., at least about 10 pounds per gallon) and/or a relatively high salinity (e.g., a total dissolved salt concentration of at least about 25 wt %). In certain embodiments, additional salt is added to the concentrated brine stream to produce an ultra-high-density brine stream (e.g., a brine stream having a density of at least about 11.7 pounds per gallon). Some aspects relate to a system that is configured to promote energy efficiency by recovering heat from the recirculated concentrated brine stream upon discharge from the fluidic circuit.

    Abstract: Described herein are systems and methods for treating an aqueous input stream comprising at least one suspended and/or emulsified immiscible phase (e.g., oil, grease) and, in some cases, one or more additional contaminants, such as solubilized bicarbonate (HCO3−) ions, solubilized divalent cations (e.g., Ca2+, Mg2+), solubilized trivalent cations (e.g., Fe3+, Al3+), organic material (e.g., humic acid, fulvic acid), hydrogen sulfide (H2S), and/or suspended solids. According to certain embodiments, the aqueous feed stream is supplied to a water treatment system comprising a chemical coagulation apparatus and a suspended solids removal apparatus (e.g., a clarifier). Within the chemical coagulation apparatus, an amount of an inorganic coagulant (e.g., aluminum chlorohydrate, polyaluminum chloride), an amount of a strong base (e.g., sodium hydroxide), and an amount of a polyelectrolyte (e.g., polyacrylamide) may be added to the aqueous input stream to form a chemically-treated stream. In some embodiments, the inorganic coagulant, strong base, and/or polyelectrolyte may induce coagulation and/or flocculation of at least a portion of the contaminants within the aqueous input stream, and the chemically-treated stream may comprise a plurality of flocs (i.e., particle agglomerates). In some embodiments, the chemically-treated stream is directed to flow to the suspended solids removal apparatus. Within the suspended solids removal apparatus, a plurality of flocs may be removed from the chemically-treated stream to form a contaminant-diminished stream having a lower concentration of contaminants than the aqueous input stream. In some embodiments, the chemically-treated stream and the contaminant-diminished stream each have a pH of about 8 or less. In some embodiments, the chemically-treated stream and the contaminant-diminished stream each have a temperature of about 15° C. or less.

    Abstract: Described herein are systems and methods for removing boron from water. According to certain embodiments, an aqueous input stream comprising boron and at least one suspended and/or emulsified immiscible phase is supplied to a water treatment system comprising a chemical coagulation apparatus, a suspended solids removal apparatus, and a boron removal apparatus. Within the chemical coagulation apparatus, an amount of an inorganic coagulant, an amount of a strong base, and an amount of a polyelectrolyte may be added to the aqueous input stream to form a chemically-treated stream. In some embodiments, the chemically-treated stream, which may comprise a plurality of floes, may be directed to flow to the suspended solids removal apparatus. Within the suspended solids removal apparatus, at least a portion of the floes may be removed from the chemically-treated stream to form a contaminant-diminished stream having a lower concentration of contaminants than the aqueous input stream.
