Abstract: Methods, systems, and apparatuses for recovering water from an aqueous stream containing a solute are disclosed herein. In accordance with an aspect, provided is method comprising receiving an inlet brine stream comprising water and a solute; producing a concentrated brine stream by contacting the inlet brine stream with an ion exchange resin configured to extract water from the inlet brine stream, the ion exchange resin comprising a plurality of pores adapted to receive water molecules; ceasing the contact of the ion exchange resin with the inlet brine stream and the concentrated brine stream; and evaporating at least a portion of the water contained in the ion exchange resin aided by unsaturated air with less than 100% relative humidity using an evaporation unit.

Abstract: An object of the present invention is to provide a chemical liquid purification method which makes it possible to obtain a chemical liquid having excellent defect inhibition performance. Another object of the present invention is to provide a chemical liquid. The chemical liquid purification method according to an embodiment of the present invention is a chemical liquid purification method including obtaining a chemical liquid by purifying a substance to be purified containing an organic solvent, in which a content of the stabilizer in the substance to be purified with respect to the total mass of the substance to be purified is equal to or greater than 0.1 mass ppm and less than 100 mass ppm.

Abstract: A lactic acid adsorbent includes at least one of a layered double hydroxide that contains multiple metal hydroxide layers and also contains anions and water molecules held between the metal hydroxide layers, or a layered double oxide that is an oxide of a layered double hydroxide. The metal hydroxide layers contain divalent metal ions M2+ and trivalent metal ions M3+, mole ratio (M2+/M3+) of the divalent metal ions M2+ to the trivalent metal ions M3+ in a layered double hydroxide is 1.9 to 3.6, and the mole ratio in a layered double oxide is 1.8 to 3.6.

Abstract: A method for recovering an acidic gas, includes: a step of bringing a gas to be treated that contains an acidic gas into gas-liquid into contact with an amine absorbing solution, allowing the amine absorbing solution to absorb the acidic gas, thereby removing the acidic gas from the gas to be treated; a step of allowing the amine absorbing solution that has absorbed the acidic gas to release the acidic gas, thereby regenerating the amine absorbing solution, and at the same time, recovering the released acidic gas; and an analysis step of calculating concentrations of iron ions and/or heavy metal ions in the amine absorbing solution.

Abstract: The present disclosure is directed to processes for reducing the endotoxin level in gelatin and the resulting gelatin with low endotoxin content. The process includes dissolving a salt in a gelatin solution and filtering the gelatin-salt solution using anion exchange to reduce the endotoxin level. After reducing the endotoxin level of the gelatin-salt solution, the low endotoxin gelatin-salt solution is desalted to remove the salt, thereby producing a low endotoxin gelatin solution.
