A water treatment process that includes associating the water treatment process with an offshore operation; receiving a treated water stream comprising floc into a flotation vessel. The process further includes injecting an injection stream into the flotation vessel to interact with the treated water stream and removing floc from the treated water stream to form a secondary treated water stream.

An advanced ozogation apparatus includes an ozone generator subsystem configured to generate ozone from ambient air. The advanced ozogation apparatus includes an advanced oxidation subsystem. The advanced oxidation subsystem includes a venturi assembly configured to generate ozonated water by combining water and the generated gaseous ozone. The advanced oxidation subsystem includes an ultraviolet reactor configured to induce hydroxyl radicals within the ozonated water. The advanced oxidation subsystem includes a retention tank configured to store the hydroxyl radical-induced ozonated water. The retention tank is configured to receive the hydroxyl radical-induced ozonated water via a mass transfer subsystem. The advanced ozogation apparatus includes a disperser configured to disperse the hydroxyl radical-induced ozonated water to one or more plants. The retention tank is configured to output the hydroxyl radical-induced ozonated water to the disperser.

A compact, portable system and process separates dissolved and suspended solids from water containing high levels of those solids. Gas flotation is used with and oxidant as an initial stage. The resulting foam is dewatered in a fluid conveyance, with the gas being recycled to the flotation column, the foam sent to a holding tank and the water passed through one of a number of filtration vessels having granular filter media. As at least one filtration vessel is kept in operation filtering, another filtration vessel can be backwashed when the flow therethrough is diminished of the fluid level inside rises. Treated water is used for backwashing and provided to a collection conduit.

A water treatment system includes a bioreactor having a tank configured to receive an influent liquid, a separator structure positioned in the tank, an aeration vent positioned in the tank and configured to direct air into the tank, but not directly into the interior of the separator structure; and an effluent outlet communicating with the interior of the separator structure through which a relatively clean effluent liquid, exits from the separator structure via the effluent outlet, a filter tank in fluid communication with the effluent outlet of the tank, and an ozone generator in communication downstream of the filter tank, for oxidizing the effluent liquid.

This application relates to an oxygen infusion module for a system and method of treating wastewater wherein an oxygen infusion system is used to supersaturate wastewater before aerobic biological processes, wherein oxygen is transferred to the wastewater free of oxygen bubbles and achieves a reduction in power demand for the aeration process of wastewater.

A method, apparatus, and system are provided, utilize a floating treatment wetland designed specifically for the sequestration of microplastic debris (i.e., plastic particles under 5 mm) from active water systems. This process can be achieved through the careful selection of a root structure combined with the development of a robust housing for the wetland pad, so that it may operate effectively in fast current conditions. Existing phytoremediation wetlands are typically deployed in static aquatic environments like reservoirs or lakes, and cannot remain stable in currents beyond speeds of 2 m/s. This currently limits their application in most rivers that typically reach speeds beyond 6 m/s, especially during storm surges. To overcome this, disclosed is a hydrodynamic fiberglass frame to encase and stabilize the floating treatment wetland during storm surges. The design of this frame may be adapted to encourage optimal flow to the underside of the wetland, in order to maximize the amount of water exposed to the wetland's biofilm filter.

A mobile mechanical vapor recompression evaporator system including a horizontal vapor separator and a horizontal forced circulation heat exchanger. The horizontal vapor separator can include a generally cylindrical housing configured in a generally horizontal orientation. The housing can include at least one product chamber having at least one product passage configured to receive at least one product. The housing further includes at least one vapor chamber having at least one vapor passage and at least one vapor window located between the at least one product chamber and the at least one vapor chamber, wherein a portion of the at least one product evaporates in the product chamber to produce a vapor that passes through the at least one vapor window into the at least one vapor chamber, and is discharged through the at least one vapor passage.

An electrocoagulation unit that may include an outer shell, and a set of electrodes disposed therein. At least two electrodes are separated from an adjacent electrode by an electrode gap. The outer shell may further include a fluid inlet; a fluid outlet; a first busbar opening with a first busbar gland associated therewith.

An electrocoagulation unit that may include an outer shell, and a set of electrodes disposed within the inner housing. Each electrode is separated from an adjacent electrode by an electrode gap spacing. The outer shell may further include a fluid inlet; a fluid outlet; a first busbar opening with a first busbar gland associated therewith.

A method and system for de-oiling a feed comprising oil and water. The feed has an input temperature above the boiling point of water and an input pressure sufficient to maintain the water in a liquid state. In at least one embodiment, the method comprises pumping the feed with a motive pump through a phase separator having a restriction to effect a phase separation of oil and water in the feed and produce an agitated mixture, supplying the agitated mixture from the phase separator into a pressure vessel operating at a pressure sufficient to maintain in a liquid state water that is at a temperature above the boiling point of water, removing an oil phase from the pressure vessel, and removing a water phase from the pressure vessel.
