The present disclosure relates to a large-scale production method of plant exosomes. The method of the present disclosure can isolate high purity plant exosomes from a large amount of raw plants, using centrifugation and TFF, which can process a large amount of plant raw materials at once. This improves a conventional isolation process of plant exosomes stayed at the laboratory level, and thereby, suggests an easy process for large-scale production.

A system and process for concentrating a lithium stream is disclosed. The lithium stream is directed to a reverse osmosis unit which produces a concentrate containing lithium compounds. The RO concentrate is directed through two pressure retarded osmosis (PRO) modules connected in series. The two PRO modules further concentrate the RO concentrate and at the same time yield a diluted brine that is effective to drive an energy recovery device. The RO concentrate leaving the PRO modules is directed to an osmotically assisted reverse osmosis (OARO) module which also further concentrates the RO concentrate.

A concentration apparatus that includes a liquid tank storing a liquid containing a filtration object, a tubular member having first and second end portions disposed in the liquid tank and forming a first circulation flow path therebetween, a circulation pump for supplying the liquid stored in the liquid tank to flow from the first end portion to the second end portion, a filtration filter disposed in a sidewall of the tubular member, a bypass pipe having first and second ends thereof connected to sidewalls of the tubular member so as to form a second circulation flow path between the first and second end portions of the tubular member, a switching valve constructed to cause the liquid to flow in one of the first or second circulation flow paths, and a control unit controlling driving of the circulation pump and a switching operation of the switching valve.

The present disclosure is in the field of ‘pharmacognosy’ and ‘chemistry of natural products’. The present disclosure generally relates to a process of isolation and purification of Biochemical Constituents from algae. The present disclosure particularly relates to a process of isolation and purification of Biochemical Constituents from a biomass of cyanobacteria. The present disclosure provides a process for isolating and extracting phycocyanins, chlorophylls, proteins and polysaccharides from the spirulina biomass.

An electrochlorination system includes an electrolyzer fluidically connectable between a source of feed fluid and a product fluid outlet, and a sub-system configured to one of increase a pH of the feed fluid, or increase a ratio of monovalent to divalent ions in the feed fluid, upstream of the electrolyzer.

Embodiments of the present disclosure include systems and methods for enhancing the performance and efficiency of separation processes. The methods include flowing a fluid through a processing zone defined by an antiferromagnetic portion of a conduit and, as the fluid flows through the processing zone, exposing the fluid to a magnetic field produced by oscillating electromagnetic waves, wherein the direction of the magnetic field is generally counter to the direction in which the fluid is flowing. The systems include magnetic treatment units, separation systems, and the like.

A control system has a water purification module and a control module. The water purification module has a preliminary filter and a reverse osmosis filter. The control module regularly controls the purification and the drainage of the water purification module, and solves the problem that the TDS value of the water on both sides of the reverse osmosis membrane is too high after the water purifier is on standby for a period of time. The control system regularly drains high concentration water on both sides of the reverse osmosis membrane to improve water purification efficiency.

A filter screening tool, system, and method allowing high throughput screening of filters (such as hollow fiber filters), such as for use in bioprocessing workflows. Feed material may be fed through different filter modules to assess, measure, analyze, determine, evaluate, teste, compare, screen, etc., properties or characteristics, etc., of filters within the filter modules. Each filter module may house a different type (e.g., material or configuration) of filter so that different filters may be compared and screened, such as for a selected use.
