Introduction Editor
The central water treatment system includes three parts: the central water purification system, the central water softening system, and the central water purification system.
Central water purification system first effectively remove chlorine, heavy metals, bacteria, viruses, algae and suspended solids in the water, and then use activated carbon to further remove a variety of organic matter, so that the water is clear, clean, halogen-free, and can be directly consumed; the system has an automatic maintenance function.
Central water softening system is through the natural resin replacement of calcium and magnesium ions in the water to reduce water hardness; effectively reduce the wear and tear of clothing, protect human skin, avoid pipelines, sanitary ware, sanitary equipment and other scaling problems.
Centralized pure water system using reverse osmosis method, the precision calculation of the five filtration procedures, so that the water into pure water, does not contain any impurities and minerals.
The centralized pure water system is a multi-functional and fully automatic device composed of pre-treatment system, reverse osmosis water purification system, EDI deep desalination system, post-treatment system, and circulating water supply system. The use of safe, convenient, low operating costs, stable water quality of fully automatic complete sets of equipment. This equipment is mainly used for centralized water supply in hemodialysis room, biochemical room, stomatology department, central laboratory of supply room, preparation room and operation room.

Centralized treatment of water
The central treatment of pure water System Application Analysis Editor
Investing in the construction of hospitals centralized centralized water production, quality water supply system can not only enhance the hospital's modern management level, more importantly, it can produce greater benefits. Centralized centralized water production, quality water supply system with its water quality can be controlled, the total investment cost is small, low operating costs, machine room optional large, small total floor space and other advantages can quickly replace the independent water machine water supply system in each department.
Overview
In the process of hospital modernization and construction, the hospital water project, although the proportion of investment is not large, but involves a wide range of departments. With the gradual improvement of hospital water quality norms, has been increasingly by the leadership of health care institutions at all levels of attention. The United States, Japan and other economically more developed countries, as early as the 1970s has been the establishment and implementation of a more sound management system for the use of pure water in hospitals and different subjects of pure water standards. Subsequently, more and more hospitals have established a centralized water system, quality water supply system. The so-called centralized water system, quality water supply, is to use a set of water machine on the tap water depth treatment, so that it can reach the water quality standards for direct use in various departments, and then separately with the pipe network to supply the use of various departments. Since the end of the 20th century, China has introduced and implemented the concept and program of centralized centralized water production and quality-separated water supply. In recent years, the centralized water system, quality water supply system, because of its unique advantages are rapidly replacing the original independent water supply equipment.
A general hospital, at least the need for biochemical testing water, pathology water, blood dialysis water, central supply room water, surgical rinse water, DSI catheter rinse water, dental rinse water, obstetrics baby wash water, preparation room water and other high-quality pure water. In China's hospital facilities, in the early 1990s before the investment in the construction of the complex, basically still using the independent water supply of pure water in various departments. In recent years, new construction, renovation of general hospitals, in order to maximize the use of resources, and further improve the degree of modernization of hospital management, one after another, the use of a centralized centralized preparation of pure water, water supply system model, the model of the basic process flow is illustrated as follows:
Analysis of the advantages of
Centralized centralized water system, water supply model has a number of advantages as follows:
1. Improve management efficiency and management level. Centralized centralized water system, quality water supply system in itself has a PLC unattended full self-control function, but also reserved with the hospital's general duty monitoring room communication protocol interface. Through the monitoring room on duty personnel can monitor the whole process, and even manipulate the system.
2. Reduce the work intensity of the front-line medical workers to enhance their professional efficiency and responsibility, but also more conducive to the maintenance and management of medical water equipment. Independent water machine supply of pure water is generally required to medical staff in various departments to manage its operation and operation. In this way, medical workers have to complete their own heavy mainline medical tasks, but also to face the operation and maintenance of water treatment equipment was not familiar with, and ultimately distracted medical workers from their professional work, but also due to a lack of basic maintenance knowledge and increase the frequency of equipment failure. Centralized pure water supply system can make up for this defect.
3. Save valuable hospital room. Each section of the independent water machine supply of pure water, its room must be selected near the point of water. Because of the departments of water treatment equipment room is relatively independent, which not only increases the difficulty of its room selection, but also had to move the main medical room for water treatment equipment room, and increase the total room area of the departments. Centralized centralized water supply system in reducing the total area of more than half of the room at the same time, the requirements of the room is also much lower, either the basement or the top floor, but also the podium, so that you can save the valuable main medical room.
4. Reduce investment in equipment and lower operating costs. Comparison with each section of the independent water machine supply of pure water, supply the same section of the water, the centralized centralized water production equipment will reduce the operating costs by more than half. Because of the centralized centralized water production equipment is relatively centralized, so that the preparation of units of pure water power consumption is greatly reduced. In addition, because the centralized water supply equipment can be 100% utilization of water resources, so it will further reduce its operating costs.
5. Water quality is more secure. Centralized centralized water system, quality water supply system because of its own structure determines the pure water delivery can be achieved closed loop water supply, and there is no stagnant water or contamination sources of the phenomenon. Coupled with pure water is basically in the state of ready-to-use, so the quality of water is strongly guaranteed.
The advantages are:
Central water purification system:
a, can remove chlorine, heavy metals, solid suspended particles in the water;
b, with sterilization;
c, through the activated carbon to remove a variety of organic matter, etc., and can be consumed directly;
d, the system has an automatic maintenance function.
Central water softening system:
a, through the natural resin replacement of calcium, magnesium ions in the water, reduce water hardness;
b, reduce the wear and tear of minerals in water on clothing and skin;
c, to avoid the pipeline, valves, sanitary equipment and household appliances in the scale, to prolong the service life;
d, to avoid the formation of yellowish color in the water, in sanitary ware, tableware and so on. Formation of yellow spots in sanitary ware, cutlery and so on.
Centralized pure water system:
a, the use of reverse osmosis method, after precision calculations to match the five filtration;
b, after treatment of water to become pure water, water quality up to the national bottled water standards.
