    Abstract: Mobile treatment systems and methods for use in removing sulfates from contaminated water using a pre-treatment subsystem configured to remove particulates and debris from the contaminated water and to produce pre-treated water; a treatment subsystem configured to remove sulfates from the pre-treated water and to produce treated water, the treatment subsystem including at least one treatment tank with a collection unit having one or more filters with pore or inlet sizes of approximately 0.35-1.2 mm; and at least one storage tank configured to collect the treated water. Optionally, the systems and methods may use a backwash subsystem configured to backwash the treatment subsystem.

    Abstract: In an ion-exchange separation system, a single regeneration column provides for separation of anion and cation resins and the regeneration of both cation and anion resins with a very low level of cross-contamination. After regeneration most of the anion layer in the column is withdrawn, and most of the cation layer is withdrawn, but a portion of each layer adjacent to the interface between the layers remains in the column, to isolate these cross-contaminated portions from the regenerated resins. The withdrawn, regenerated anion and cation resins are placed back into the working vessel.

    Abstract: Provided herein are methods, systems, and computer-readable media for controlling a deacidification process for an aqueous fluid circulated through a deacidification column. A first pH value, indicative of a pH of the fluid before circulation through the column, is obtained from a first sensor located at an entry of the column. A second pH value, indicative of a pH of the fluid after circulation through the column, is obtained from a second sensor located at an exit of the column. The second pH value is compared to a target pH value for the fluid to determine a pH difference between the second pH value and the target pH value. Based on the first and second pH values, a deacidification capacity of the column is determined. A fluid flow rate of the fluid through the column is adjusted based on the pH difference and the deacidification capacity.

    Abstract: The present invention provides a method of converting a brominated hydrocarbon to a chlorinated hydrocarbon that involves contacting together the brominated hydrocarbon and a chlorinated ion exchange resin that has a water content of less than or equal to 30 percent by weight, based on the total weight of the chlorinated ion exchange resin and the water. The brominated hydrocarbon includes at least one replaceable bromo group, where each replaceable bromo group is independently covalently bonded to an sp3 hybridized carbon. Contact between the brominated hydrocarbon and the chlorinated ion exchange resin results in replacement of at least one replaceable bromo group of the brominated hydrocarbon with a chloro group, and correspondingly conversion of at least a portion of the brominated hydrocarbon to the chlorinated hydrocarbon.
