water treatment equipment

Water is the source of life. In recent years, water has been seriously polluted. People's demand for high-quality water has become more and more urgent. Therefore, water treatment equipment has been widely used. Taking water purification control as an example, its It is very common to play the main control role in the monitoring and control functions such as water intake, dosing, filtering, and water delivery required within the scope of the water plant. Correspondingly, there will also be a relatively large demand for a large number of human-machine interface display instruments, magnetic flap level gauges, full-process water processors, electromagnetic flow meters and other instruments.
In terms of water quality monitoring and water status measurement, a large number of instrumentation products need to be applied. These instruments and meters used in the water treatment industry are mainly divided into process instruments and analytical instruments. Process instruments include temperature, liquid level instruments, flow meters, pressure transmitters, valves, actuators, etc., while the types of analytical instruments are very It is large and fine, and must be used in conjunction with the corresponding treatment process according to the actual water quality type of the water source being treated. For different types of sewage, such as industrial wastewater and biological wastewater, the treatment processes may vary greatly.
Since distributed control systems are commonly used for hierarchical control management, there are also very high requirements for the industrial communication methods they rely on. In recent years, from the relatively popular fieldbus to the relatively new industrial Ethernet, they have been applied on a large scale, and the effects have been increasingly improved. It is worth mentioning that in order to meet the application of some special occasions such as remote monitoring, wireless communication technology has also intervened in the water treatment industry and achieved good results. This is undoubtedly an excellent method for wired communication. Replenish.
In the actuator link, the application of frequency converters is becoming more and more common. Frequency converters have multiple advantages when applied to loads such as blowers and water pumps. Compared with the adjustment method of valve dampers, variable frequency speed regulation can make the speed-regulated objects run in an energy-saving state. In principle, a large amount of cost savings can be achieved. At the same time, using frequency conversion The actuator also reduces the mechanical loss of the pressure calibrator, reduces the impact of the actuator, and can also protect the power grid.
China's water industry is still in the growth stage. Although the government has determined the strategic goal of water marketization, there is a lack of systematic research on the path of water market reform. The market-oriented policy system for urban water affairs is imperfect. In view of the differences in local conditions, Differences, cost monitoring and accounting, and water price adjustment time and intensity have certain uncertainties, causing water investment with long-term investment characteristics to face greater policy risks. At the same time, the competition for various types of capital has intensified competition in the current water market.
In addition, the market concentration is low, there is a lack of industry leaders, and the characteristics of regional monopoly are obvious. Based on industry attractiveness and technological relevance, the industry chain will be extended vertically, and water affairs integration will become the main development direction. Operational management capabilities, capital operation capabilities, market development capabilities, technology application and development capabilities, and risk control capabilities have become key success factors for enterprises in the water industry. Finding a balance between market share and investment returns is the focus of Chinese water companies' growth at this stage.
