The water-supplying step includes a first water-supplying step in which a slime controlling agent X which contains 2,2-dibromo-3-nitrilopropionamide (DBNPA) and a slime controlling agent Y which contains at least one type selected from a group consisting of components (A) to (D) are added to the water to be treated which has a pH of 10 or less, and the water to be treated which contains the slime controlling agent X and the slime controlling agent Y is supplied to the reverse osmosis membrane. The component (A) is mixture of 5-chloro-2-methyl-4-isothiazolin-3-one (Cl-MIT) and 2-methyl-4-isothiazolin-3-one (MIT), the component (B) is chloramine compound, the component (C) is stabilized bromide, and the component (D) is glutaraldehyde.

摘要： The present technology includes methods for rinsing an electroplating apparatus, a component thereof, and/or a substrate. The method includes removing at least a portion of a bath solution having a first pH from an electroplating bath. The method includes filtering the removed bath solution through a nanofiltration membrane, forming a permeating containing a recycled rinse agent, and a retentate. The method includes transferring the recycled rinse agent to the one or more nozzles and rinsing the electroplating apparatus, component thereof, and/or substrate. The method includes where the recycled rinse agent is characterized by a second pH, where the second pH varies from the first pH by less than or about 5.

摘要： The present invention concerns a process for the recovery and purification of glyoxylic acid from a process stream comprising glyoxylic acid and oxalic acid, wherein the process stream comprising glyoxylic acid and oxalic acid is subjected to a number of alternating separation and dehydration steps. The process comprising the steps of: (i) providing an aqueous solution comprising glyoxylic acid and oxalic acid; (ii) precipitating at least a portion of the oxalic acid using low-temperature crystallization at a temperature of at most 18° C.; (iii) separating the precipitated oxalic acid from the solution to obtain a solution depleted in oxalic acid; (iv) concentrating the solution depleted in oxalic obtained in step (iii) using reverse osmosis; and repeating steps (ii)-(iv) with the concentrated solution obtained in step (iv) until a purified glyoxylic acid stream with a predetermined degree of purity is obtained. The invention also relates to a system for carrying out the process.

摘要： The present invention relates to processes and systems for ammonia recovery and/or acid-gas separation. In some embodiments, a system for acid gas separation may be integrated with an ammonia abatement cycle employing a high temperature absorber. In some embodiments, a system for acid gas separation may employ a higher temperature absorber due to the lower energy consumption and cost of the integrated ammonia abatement cycle. Advantageously, heat may be recovered from the absorber to power at least a portion of any acid gas desorption in the process. Reverse osmosis or other membranes may be employed.
