A new apparatus, system and method to purified produced water and removed valuable metals and minerals is described. The apparatus comprises a device for flowing produced water wellbore from a wellbore to the produced water purification apparatus; at least one device to remove heavy metals from the produced water; at least one brine removal device to remove brine from the produced water. The method comprises steps to use the apparatus and the system comprises a control panel that operates the at least one device for removing heavy metals and at least one sensor in a coordinated manner.

Provided are methods, devices, and kits for the isolation of extracellular vesicles using silicon nanomembranes. A method for EV isolation includes the steps of collecting a biofluid sample, contacting the biofluid sample with a pre-filtration membrane, thereby forming a first filtrate and a first retentate, optionally, washing the first retentate of the pre-filtration membrane, contacting the first filtrate from the pre-filtration membrane with a capture membrane, thereb forming a second filtrate and a second retentate, optionally, washing the second retentate, and eluting the second retentate from the capture membrane or lysing the second retentate to recover the contents.

A method for producing an aligned boron nitride nanotube film includes drying a dispersion containing boron nitride nanotubes, a biopolymer, and a solvent.

A method including contacting a stream including water with a coated porous substrate including a porous substrate coated with a hydrophilic and oleophobic coating to produce a treated water including water that passes through the coated porous substrate; and utilizing at least a portion of the treated water as a component of a hydraulic fracturing fluid.

Disclosed is an apparatus for water treatment, including a membrane separator for solid-liquid separation; and a particle fractionator which has at least two exits of a fractionated solid-liquid mixture produced therein, wherein a liquor containing particles of different sizes including submicron particles is fed to the particle fractionator before a membrane separation by the membrane separator, and wherein a first fraction of the fractionated solid-liquid mixture is returned to the membrane separator from one exit of the at least two exits of the particle fractionator, the first fraction being less than the liquor in terms of content of the submicron particles. This apparatus enables a rapid achievement of suppression of membrane fouling.

The present disclosure provides methods of preparing a high color concentrate (HCC) wine. Aspects of the methods may include obtaining a grape fluid composition from one or more grapes, contacting the grape fluid composition with a reagent to modify the pH, adding an amount of distilled alcohol to the grape fluid composition to produce a fortified wine composition, and concentrating the fortified wine composition to produce an HCC wine. Aspects of the methods may further include obtaining a must from one or more grapes, fermenting the must to produce a grape fluid composition having a percent alcohol content, contacting the grape fluid composition with a reagent to modify the pH, and concentrating the grape fluid composition to produce an HCC wine. Also provided is a composition including the HCC wine produced according to the subject methods.

A method of producing a sugar liquid derived from a cellulose-containing biomass includes (a) saccharifying a pretreated product having alignin content of not more than 8.5% obtained by pretreatment of a cellulose-containing biomass, to obtain a saccharified liquid; (b) filtering the saccharified liquid obtained in Step (a) through a microfiltration membrane to allow formation of a cake on a membrane surface in a feed side while obtaining a sugar liquid from a permeate side; and (c) collecting the cake formed on the membrane surface in Step (b) by peeling from the membrane.

A blood processing system for collecting plasma reduced platelets and anticipating plasma return includes a venous access device, a blood component separation device, a first return line, a recirculation line, and a second return line. The venous access device draws whole blood from a subject and returns blood components to the subject using a first pump. The blood component separation device separates the drawn blood into a first blood component and a second blood component, and sends the first blood component to a first blood component bag. The first return line fluidly connects the venous-access device and the blood component separation device. The recirculation line connects the first blood component container and the separation device. The second return line fluidly connects the first blood component container and the first return line and is configured to return the first blood component within the first blood container to the subject.
