The installation for separating a multivalent cationic species from a solution comprising this multivalent cationic species and lithium comprises a capture device (3) having an entry (2) and an exit (4). The capture device (3) comprises, between the entry (2) and the exit (4), a microfibre product (12) with a higher affinity for multivalent cations than for monovalent cations. The installation comprises a circulation system (5) adapted to circulate the solution from the entry (2) to the exit (4) in contact with the microfiber product (21), the microfibre product (21) capturing said multivalent cationic species.

The present invention relates to recovery of lithium from liquid resources to produce lithium solutions while limiting impurity precipitation in the lithium solutions.

A heavy metal capture composition, devices including the composition, and a method of reducing heavy metal contamination in the environment is described.

The present disclosure relates to the use of a strongly basic anion exchange resin, in the form of dimethylethanolamine (DMAE) resin, for the removal of the per- and polyfluoroalkyl substances (PFASs) from fluids such as water.

An ion exchanger filled cartridge accommodated inside an accommodating container of a metal removing column and in which an ion exchanger is filled is provided. The ion exchanger filled cartridge includes a cylinder portion, an upper lid in which a through hole for a liquid to be treated is formed and which is provided on an upper end of the cylinder portion, a lower lid in which a through hole for a treated liquid is formed and which is provided on a lower end of the cylinder portion, an insertion pipe connected to the lower lid, having an O-ring attached to an outer side, and inserted into a treated liquid discharge pipe provided on a bottom portion of the accommodating container of the metal removing column, and the ion exchanger filled inside the cylinder portion.

The present invention relates to a method for identifying the unit causing a raw water leak in a condenser of a thermal power plant consisting of n units.

A two-step chromatography purification scheme is described which selectively captures and isolates the genome-containing rAAV vector particles from the clarified, concentrated supernatant of a rAAV production cell culture. The process utilizes an affinity capture method performed at a high salt concentration followed by an anion exchange resin method performed at high pH to provide rAAV vector particles which are substantially free of rAAV intermediates.
