    Abstract: Apparatus for purifying a fluid, which comprises an ion absorption cell (2) traversed by a fluid to be treated (F1) containing cationic particles and/or anionic particles, provided with a containment structure (3) defining at its interior two operating chambers (4, 5) traversed by the fluid to be treated (F1), and each delimited by a respective electrode (10, 11) that can be power supplied to opposite polarities. Between the two operating chambers (4, 5), a third evacuation chamber (13) is interposed, containing a porous electrical conductor (18) traversed by a washing fluid (F2) and delimited by two opposite walls (16, 17) which together with the electrodes (10, 11) define the aforesaid operating chambers (4, 5). The aforesaid walls (16, 17) have at least one ion-selective area associated, which is susceptible to being traversed by charged particles with corresponding polarity contained in the two contiguous operating chambers (4, 5) subjected to the action of the electric field generated by the electrodes. The porous electrical conductor (18) is in turn susceptible to reduce the electric field inside the third evacuation chamber (13) such that the ion-selective areas of the walls of the third evacuation chamber (13) are capable of repelling the charged particles with corresponding polarity contained in the third evacuation chamber (13) and subjected to the action of the electric field reduced due to the shielding effect of the porous electrical conductor (18).

    Abstract: Apparatus for purifying a fluid, which comprises at least one ion absorption cell (2) with an operating chamber (4, 5) at its interior through which a first operative fluid (F1) flows and an evacuation chamber (13, 13′) through which a second operative fluid (F2, F2′) flows and which is separated from the operating chamber (4,5) by a filtering membrane (100). A porous electrical conductor (18) is housed in the evacuation chamber (13, 13′) and is traversed by the second operative fluid (F2, F2′). Two electrodes (A, B) have the aforesaid operating chamber (4, 5) and evacuation chamber (13, 13′) interposed, and are supplied with opposite polarities in order to generate an operative electric field in the operating chamber (4, 5) and a limited electric field in the evacuation chamber (13, 13′), the latter with value lower than the operative electric field, due to the shielding effect of the porous electrical conductor (18). The charged particles contained in the operating chamber (4, 5) are susceptible of traversing the filtering membrane (100) under the action of the operative electric field generated by the electrodes (A, B), and be evacuated by the second operative fluid (F2, F2′) in the evacuation chamber (13, 13′), in which they are subjected to the action of the limited electric field.

    Abstract: Electrocoagulation may be used to reduce the concentration of zinc ions in produced water. For example, a method may induce producing a wellbore fluid from a subterranean formation, the wellbore fluid comprising hydrocarbons and water, the water having zinc ions dispersed therein at a concentration greater than about 1 ppm; separating the hydrocarbons from the water; and separating at least some of the zinc ions from the water via electrocoagulation to yield an effluent water and precipitated zinc salts.
