Overview of hospital pure water treatment equipment

In the process of modernizing hospitals, although the investment in hospital pure water engineering is not significant, it involves a wide range of departments. With the gradual improvement of hospital water quality standards, it has received increasing attention from medical and health institutions at all levels. Economically developed countries such as the United States and Japan have established and implemented relatively sound hospital pure water usage management systems and pure water standards for different subjects as early as the 1970s. Subsequently, more and more hospitals established centralized water production and quality based water supply systems. The so-called centralized water production and differentiated water supply refer to using a set of water machines to deeply treat tap water to meet the water quality standards that can be directly used by various departments, and then supplying it to each department separately through pipeline networks. Since the end of the 20th century, China has introduced and implemented the concept and plan of centralized water production and differentiated water supply. In recent years, centralized water production and quality based water supply systems have been rapidly replacing existing independent water supply equipment due to their advantages.

A comprehensive hospital requires high-quality pure water such as biochemical testing water, pathology department water, hemodialysis water, central supply room water, surgical flushing water, DSI catheter flushing water, dental flushing water, obstetric baby wash water, and preparation room water. In the current facilities of hospitals in our country, the comprehensive buildings invested and constructed before the early 1990s basically still use independent water machines from each department to supply pure water. In recent years, in order to maximize the utilization of resources and further improve the modernization of hospital management, centralized preparation of pure water and quality based water supply system models have been adopted in newly built and renovated comprehensive hospitals.

The application scope of pure water treatment in hospitals: investing in centralized water production and quality based water supply systems in hospitals can not only improve the modern management level of hospitals, but more importantly, it can generate greater benefits. *The centralized water production and quality based water supply system has many advantages in terms of water quality

1. Improve hospital management efficiency and level. *The centralized water production and quality based water supply system not only has PLC unmanned and fully automatic control functions, but also reserves communication protocol interfaces with the hospital's duty monitoring room. The on duty personnel in the monitoring room can monitor and even operate the system throughout the entire process.

2. Reduce the workload of frontline medical workers, improve their professional work efficiency and sense of responsibility, and also facilitate the maintenance and management of pure water equipment. The supply of pure water by independent water machines generally requires medical staff from each department to manage their operation and operation. In this way, medical workers not only have to complete their heavy mainline medical tasks, but also face the operation and maintenance of unfamiliar water treatment equipment, which ultimately distracts them from professional work and increases the frequency of equipment failures due to a lack of basic maintenance knowledge. *A pure water supply system can compensate for this deficiency.

3. Save valuable hospital space. Each department is equipped with an independent water dispenser to supply pure water, and the room must be located near the water point. Due to the relative independence of the water treatment equipment rooms in each department, it not only increases the difficulty of selecting their rooms, but also forces the main rooms to be relocated to water treatment equipment rooms, and increases the total room area of each department. *The centralized supply system for pure water not only reduces the total floor area by more than half, but also greatly reduces the requirements for housing resources, which can be either basement or top floor, or podium buildings, thus saving valuable main buildings.

4. Reduce equipment investment and lower operating costs. Compared with independent pure water machines supplying pure water to each department, centralized water production equipment can reduce operating costs by more than half when supplying water to the same department. Due to the relatively centralized water production equipment, the power consumption for preparing a unit of pure water is greatly reduced. In addition, since pure water supply equipment can fully utilize water resources, it will further reduce its operating costs.

5. Water quality is more guaranteed. *The centralized water production and quality based water supply systems, due to their own structure, can achieve closed-loop water supply for pure water transportation, and there is no phenomenon of stagnant water or pollution sources. In addition, pure water is basically in a ready to use state, which effectively ensures the quality of water used.
