Methods and systems of a biosolids concentrator and digester system having an inlet, an equalization/separation tank, an equalization/separation tank-anaerobic tank connector, an anaerobic tank, an anaerobic tank-aerobic tank connector, an aerobic tank, an aerobic tank-clarifier tank connector, and a clarifier tank. The inlet receives a thermally treated waste stream (TTWS), which enters the equalization/separation tank through the inlet at the equalization/separation tank bottom portion and leaves at the equalization/separation tank top portion. The TTWS enters the anaerobic tank at the anaerobic tank bottom portion and is anaerobically digested in the anaerobic tank producing a biogas, which is discharged from the anaerobic tank top portion. The TTWS leaves the anaerobic tank at the anaerobic top portion, enters the aerobic tank at the aerobic tank bottom portion and leaves the aerobic tank at the anaerobic top portion.

A supercoil filtration unit is provided. The supercoil filtration unit includes an outer coil, and an inner coil disposed within the outer coil. The inner coil includes a plurality of hollow fiber membranes which are aligned and arranged into a helical bundle containing multiple turns of the inner coil per turn of the outer coil. The supercoil filtration unit further includes a feed inlet, a permeate outlet, and a retentate outlet. The feed inlet is disposed upon the outer coil and in fluid communication with a first interior volume. The permeate outlet is disposed upon the outer coil at a location distant from the feed inlet and in fluid communication with a second interior volume. The retentate outlet is disposed upon the outer coil at a location distant from the feed inlet and in fluid communication with the first interior volume.

The present system is for integrated management of associated gas and produced water at oil well extraction sites. The system includes a controller that makes gas allocation determination (e.g., directs conditioned gas to (i) gas flare, (ii) produced water reduction system, and/or (iii) generator) when a change in conditioned gas flow is detected based on first plurality of inputs. If the conditioned gas is directed to the generator, then the controller makes an electricity allocation determination (e.g., (i) increase a data processing operating rate on a data processing server, (ii) start up idle data processing equipment, (iii) direct generated electric current to a power grid, and/or (iv) charge a storage battery) based on second plurality of inputs. By operating the system of gas consumption and electricity production/consumption in an integrated fashion, benefits of flaring prevention, resource conversation, and more efficient economic operations are optimized to a degree not previously attainable.

The present invention provides a method of deionization of a liquid including passing feedwater to be deionized through a deionization fuel cell system, which includes a deionization fuel cell (DFC), containing, inter alia, a cation exchange membrane and an anion exchange membrane and discharging the DFC to produce electricity and deionized liquid, wherein the method does not include a step of charging the fuel cell prior to or following the discharge step. Further provided are deionization fuel cell systems comprising a DFC comprising two or more membranes.

A solution for irradiating a flowing fluid through a channel with ultraviolet radiation is provided. Ultraviolet radiation sources can be located within the channel in order to direct ultraviolet radiation towards the flowing fluid and/or the interior of the channel. A valve can be located adjacent to the channel to control the flow rate of the fluid. A control system can control and adjust the ultraviolet radiation based on the flow rate of the fluid and a user input component can receive a user input for the control system to adjust the ultraviolet radiation. The ultraviolet radiation sources, the control system, the user input component, and any other components that require electricity can receive power from a rechargeable power supply. An electrical generator located within the channel can convert energy from the fluid flowing through the channel into electricity for charging the rechargeable power supply.

Apparatuses for removal of solids from water comprising a heater for heating an immiscible liquid (IL), a humidifier having porous sheets allowing direct contact between the IL and water, thereby separating the solids by evaporating the water into cool dry air flowing past the porous sheets, and a dehumidifier comprising porous sheets that allow direct contact between the cool IL and hot moist air flowing past the porous sheets, thereby condensing fresh water from the moist air. Also disclosed are methods for removal of solids from water by heating an IL, distributing the IL to porous sheets in a humidifier, distributing water with dissolved solids to the porous sheets, separating the solids from the water by evaporating the water into dry air flowing past the porous sheets, and condensing fresh water by flowing the moist air past porous sheets in a dehumidifier having cool IL distributed to the porous sheets.

A method and device for continuous batch separation where batch reset time is eliminated is provided. Separation is achieved in passes employing more than one liquid container or chamber. First pass begins with batch feed solution from a source reservoir, the feed solution flows from the source reservoir, undergoes separation in the separation device and the retentate is returned to a receiving reservoir until the source reservoir is evacuated. On feed switch over sequence, all pass one solution present in the holdup volume of the system is replaced with pass two solution with minimal to no mixing between the two solutions. Separation continues during the switch over sequence. The batch continues with subsequent passes until desired separation or operating conditions are met. Feed solution for the next batch is filled and kept ready during separation of a batch. Similar feed switch over sequence is followed between batches.

A system for desalination of salt water, the system including a crude oil refinery or hydrocarbon refinery, the crude oil refinery or hydrocarbon refinery including a furnace operable to produce a hot flue gas. The furnace including a radiant section, a convection section located above the radiant section, a flue gas stack located above the convection section, a heating coil located in a flow path of a flue gas in the flue gas stack such that the flue gas is capable of increasing a temperature of a water stream, thereby converting at least a portion of the water into steam, and a multi effect desalination plant configured for using the steam to produce a desalinated water.

A bio-trickling filter box device capable of purifying organic wastewater and generating electricity is provided, which includes battery component(s) and a bio-trickling filter box component. The battery component(s) is provided in the bio-trickling filter box. The other end of each of trickling filter tube(s) is connected with a water tank. A water pump operates to make water flow through the trickling filter tube(s), pass through leakage holes and trickling holes, and drip into the battery component(s) in a water-drop manner, so as to supply an electric apparatus component with power. The bio-trickling filter box component(s) and the battery component(s) are combined, and the long-term impingement of water droplets on the battery component(s) can accumulate electric charge and generate the electricity. so as to provide power required by the electric apparatus component, which forms a biological treatment system that generates the power while treating the wastewater.
