A method for separation of proteins, particularly plant proteins, from salts and phenolic compounds in a liquid comprising said proteins dissolved in said liquid is provided. The method includes a step of subjecting said liquid to a first cross-flow membrane filtration process wherein the first salts and at least a portion of the phenolic compounds migrate across the membrane into a first permeate and the proteins are retained in a first retentate; followed by a step of adding water, or one or more second salts and water to the first retentate, while continuing the membrane filtration process, to create a diafiltrate containing at least a portion of said phenolic compounds and the added second salts.

A method for the desalination of water, carried out in one embodiment on the basis of a borehole (4) in permeable coastal land, in which two internal wells (5, 6) are interconnected at the bottom, by means of a membrane packet (9), disposed such that the supply flow provided via the borehole (4) flows in a downward direction by the suction of a motor pump (7) installed at a shallow depth inside the well (5), with an ascending flow, pouring same to the marine outlet and the diluted flow (permeate) drains from the membrane packets (9) to the second well (6), which is hollow and at atmospheric pressure, where a motor pump (8) extracts the permeate for the use thereof, while in another embodiment the membrane packets (15) may be disposed in ducts hanging from a floating platform anchored in the sea or other salty water.

A whole blood filtration device is provided with a filter membrane separating a feeding volume and a clean side of the filter membrane from each other. The feeding volume communicates with a first feeding side opening and with a second feeding side opening. The filter membrane has pores with a pore size that ensures permeability of the filter membrane to blood plasma/serum and that retains blood cells. The first feeding side opening can be coupled to a first blood pump for feeding blood from the first feeding side opening into the feeding volume so that blood plasma/serum permeates the filter membrane and blood cells, retained by the filter membrane, exit from the feeding volume through the second feeding side opening.

The present disclosure relates, according to some embodiments, to systems for purifying proteins and carbohydrate rich products from photosynthetic aquatic species and compositions thereof. In some embodiments, a system for recovering a highly soluble protein product from a biomass comprising a microcrop (e.g., Lemna) may comprise (a) a lysing unit to lyse a first portion of the biomass to form a first portion of lysed biomass, (b) a first separating unit to separate the first portion of lysed biomass to generate a first portion of a juice fraction and a first portion of a solid fraction, (c) a second separating unit to separate the first portion of the juice fraction to generate a first portion of a first juice and a first portion of a first cake, (d) a first filtration unit to filter the first portion of the first juice to generate a first portion of a soluble protein and a first reject stream, (e) a second filtration unit to filter the first portion of the soluble protein to generate a first portion of a second soluble protein and a second reject stream, (f) a dewatering unit to concentrate the first portion of the second soluble protein to generate a first portion of a concentrated soluble protein, and (g) a drying unit to dry the first portion of the concentrated soluble protein to generate a first portion of a dry protein concentrate.

Methods of recovering lithium from a lithium source or a lithium-containing material using low pH solutions and membrane technologies to purify and concentrate the recovered lithium. The lithium sources may include a spent lithium-ion battery/cell, a lithium-containing mineral deposit, or other lithium containing materials. The processes described herein recovery the lithium after digestion of the lithium-containing material with a low pH solution through one or more acid-stable, semipermeable membranes.

A method for process a chemical liquid is provided. The method includes at least providing a system having at least one filtration medium, treatment the system with a treatment liquid having a content of iron (Fe) and calcium (Ca) of about 10 ppb or less, and processing a chemical liquid using an apparatus having the system configured therein after the treatment process.

The present disclosure relates to luterion, which is a mitochondrial-like micro-material, and separating and culturing methods for same and, more particularly, to a method for separating luterion by means of a filter having a pore of a particular size, luterion which is separated by means of the method thereof and has unique properties, and a culturing method for proliferation of the luterion.

The present disclosure relates, according to some embodiments, to methods and systems for purifying proteins and carbohydrate rich products from photosynthetic aquatic species and compositions thereof. For example, one embodiment of the present disclosure relates to methods and systems for purifying proteins the present disclosure relates, in some embodiments to methods and systems for extracting proteins, dry biocrude, and carbohydrate-rich meal from Lemna. In some embodiments, a method of treating a biomass comprising a microcrop (e.g., Lemna) to produce a product comprising soluble microcrop protein may comprise: (a) lysing a first portion of the biomass to form a first portion of lysed biomass; (b) separating the first portion of lysed biomass to generate a first portion of a juice fraction and a first portion of a solid fraction; (c) separating the first portion of the juice fraction to generate a first portion of a first juice and a first portion of a first cake, wherein the first juice comprises a soluble microcrop protein; and/or (d) filtering the first portion of the first juice to generate a first portion of the product comprising soluble microcrop protein and a reject stream.
