A Brief Discussion on the Importance of Medical Pure Water Machines Based on the Classification of Medical Water

Medical pure water systems are common pure water equipment in medical facilities. Medical water directly affects patient health; substandard medical water can easily lead to infections. Therefore, hospitals have strict standards for selecting medical water. Based on usage purpose and requirements, medical water can be broadly categorized into ordinary water, water for injection, purified water, and ultrapure water prepared by a medical ultrapure water system.

I. Ordinary Water

This generally refers to tap water and well water, suitable only for general washing. It contains impurities such as chlorine and cannot be used in pharmaceutical preparations, as it will cause unpleasant odors, turbidity, and precipitation.

II. Purified Water

In the pharmaceutical industry, purified water is referred to as purified water. Its conductivity is typically required to be <5 μS/cm. Purified water is used for preparations, drug dispensing, endoscope cleaning, dental chair cleaning, sterilization center cleaning, and operating room water, etc.

III. Water for Injection

Water for injection must meet the following requirements: It must be free of aerobic bacteria, anaerobic bacteria, molds, viruses, etc., during sterility testing; its purity must meet or exceed the standard of refined water, and it must be free of organic matter, colloids, dissolved gases, etc.; it must pass the pyrogenic substance test. Water for injection is generally produced using a multi-effect distillation system to ensure that pyrogenic substances meet the standards.

IV. Ultrapure Water

Medical ultrapure water systems employ a combination of multi-stage membrane treatment technology and ultraviolet sterilization, effectively removing impurities, bacteria, odors, organic matter, etc., from natural water. The ultrapure water produced meets national standards for medical water. Therefore, ultrapure water is used in medical testing, PCR, pharmacology, pathology, gene testing, in vitro fertilization, and bioengineering research.

In recent years, newly built and renovated comprehensive hospitals have adopted medical central differentiated water supply systems in order to maximize resource utilization and further improve the level of hospital modernization management. The system sets different treatment levels according to the different water quality requirements of different water points and delivers the water to the water points through different pipelines. This can effectively save equipment rooms, facilitate centralized management, and facilitate water quality monitoring.

The ULPS series of customized ultrapure water systems from UPP serves as a centralized branch-type water supply system for laboratory departments, capable of meeting various experimental needs. The produced water quality meets the Class I water quality requirements of GB/T6682-2008, ASTM, NCCLS, and ISO3696:1987 standards, making it a high-end ultrapure water preparation system for hospital laboratories.
