Problems solved by technology

For the complex separation problem of preparing pharmaceutical water, it is necessary to combine membrane technology with traditional technology. The water utilization rate of process ② is too low, consumes a lot of energy, and the volume and quality of the equipment are relatively large, especially if the water production of the equipment is 100L / For those below h, the standard water utilization rate is generally only 15%-30%, and the quality of equipment with a water production rate of 20L / h is generally ≥80Kg; process ③ Electrodeionization technology requires a relatively constant current DC power supply, and the electrodeionization membrane The cost of the stack is high, the quality is large, and it is inconvenient to replace, so it is difficult to meet the emergency conditions in the field.
In addition, none of the above-mentioned preparation processes has safe and reliable product water quality assurance technology, especially the quality control of bacteria and bacterial endotoxins in product water, which cannot meet the requirements of the Pharmacopoeia under emergency conditions

Abstract

The invention discloses a portable emergent pharmaceutical water preparation process and a portable emergent pharmaceutical water preparation device. By an advanced pharmaceutical water preparation process combining a reverse osmosis and charging microporous membrane forming and separation technology with a high-efficient ion exchange technology, a reasonable process optimization design and a mechanical and electrical integration structural design, a portable emergent pharmaceutical water device is provided, so that the aims that equipment has small volume and light weight and is portable are fulfilled, the defect of overweight loads of an ion exchange resin unit is overcome to a great extent according to a high salt rejection rate and low pressure reverse osmosis, the adsorption saturation period of anion and cation ion exchange resin is greatly prolonged, and water preparation cost is reduced.

Description

technical field [0001] The invention relates to a process and device for preparing pharmaceutical water integrated with membrane separation and ion exchange, which belongs to the field of pharmaceutical water preparation, and in particular relates to using emergency water sources to directly prepare purified water conforming to the national pharmacopoeia under field emergency conditions. Background technique [0002] For a long time, in the field of pharmaceutical water preparation, most of the purified water was produced by distillation. With the maturity of membrane separation technology and electrodeionization technology, equipment using reverse osmosis / electrodeionization as the main process to produce pharmaceutical water began to appear: For example, in the invention patent 99111578.3, ultrafiltration is used as the pretreatment unit, reverse osmosis is used for primary desalination, and electrodeionization is used as a deep desalination process. However, the mass of th...
