The hottest water treatment industry is expected t

  • Detail

The water treatment industry is expected to recover, and the potential of automation technology is considerable.

editor's note: the water treatment industry is a typical industry for the systematic application of automation technology, and it also brings considerable opportunities for various automation products. Then, in the long run, can the development potential of this industry support it to become a powerful booster to drive the demand for automation products

water is not only a common raw material in industrial production, but also an important resource necessary for people's life, so it is of great significance. In order to better realize the availability and renewability of water and provide an important guarantee of water resources for people's production and life, the water treatment industry has become an indispensable part of cities and enterprises. With the continuous development of the modern water industry and the technological innovation of related equipment, automation technology is also increasingly going deep into the water treatment industry, giving play to its control, monitoring and other functions, and improving the efficiency and progressiveness of the industry

recently, due to the impact of the economic crisis, many industries have been impacted to varying degrees. From the current series of data and information, the water treatment industry and its related equipment market have indeed been affected to a certain extent. Is this effect long-term or temporary? What development potential will the development trend of water treatment industry bring to the automation market? In the market column of this issue, we will try to discuss these issues

short term factors have limited impact on the market

for the water treatment and related equipment market, the situation in the past period is indeed in contrast to the previous development trend of rapid growth. Especially in the initial stage of the crisis, according to the reflection of the industry, many water treatment projects that were originally scheduled to be implemented were either reduced in scale or temporarily stopped, and the number of new projects was also very limited, which had a great impact on both the providers of complete water treatment solutions and the sellers of related equipment. Some known data also reflect this downturn from the side. The data released by China Machinery Industry Federation shows that the output of most instrument products fell across the board in the first half of 2009, and the environmental pollution prevention and control equipment also fell almost comprehensively, including the decline of water pollution prevention and control equipment, which reached 52.13%

analyze the reasons for the temporary setback of the water treatment business and equipment market, mainly including the following factors: first, the severe economic situation has temporarily reduced the attention of some enterprises to industrial sewage treatment and other environmental protection measures for the sake of saving expenses, and also reduced the investment in these projects, which has greatly reduced the demand for production sewage treatment with enterprises as the main body; Secondly, the role of a series of macro policies aimed at buying vegetables and fruits in response to the crisis 320 sound-absorbing materials and components need a certain amount of time in various industries. For some non-public water treatment projects, the benign effect will reflect a certain delay

there are many potential applications of automation technology

what people usually call water treatment mainly includes sewage treatment and water purification treatment, and sewage treatment is divided into industrial wastewater treatment and domestic water treatment. These different kinds of water treatment processes have their own characteristics in terms of water quality requirements and treatment steps. At present, the requirements for sewage treatment are not only to make it harmless, but also to recycle it, or collect the heat energy in the wastewater for reuse. These steps and requirements require a considerable degree of automation of the water treatment system, which is undoubtedly a good market for automation products

in principle, water treatment is generally a very complex process. At the same time, due to the characteristics and business model of domestic water treatment industry, multi-level and multi-step control management is often required. From the on-site slave station that realizes various steps and functions, to the water plant or sewage treatment plant, Gerresheimer gathered its glass production in Binde, and then to the upper level group company, including monitoring, control, execution, scheduling, management, diagnosis and other functions and tasks. If the modern water treatment industry is separated from automatic products and technologies, it can be said that it cannot operate effectively, let alone achieve safety High requirements in intelligence, etc

at present, for the control needs of the water treatment industry, the performance characteristics of PLC controllers are the most suitable for this industry, so they have also been widely used in the distributed control system of water treatment. Taking water purification control as an example, it plays a very common role in the monitoring and control functions of water intake, dosing, filter, water delivery, etc. required within the scope of water plants. From the management level of the whole group company, SCADA system is often used for macro command, scheduling and management to truly achieve the effect and requirements of "centralized command and decentralized control". Accordingly, a large number of human-machine interfaces, display instruments, etc. will also have a relatively large demand

in terms of water quality monitoring and water state measurement, a large number of instruments and meters need to be used. These instruments and meters used in the water treatment industry are mainly divided into process instruments and analytical instruments. Process instruments include temperature, pressure transmitters, liquid level instruments, flow meters, valve products, actuators, etc., while the types of analytical instruments are very many and detailed, which must be used in combination with the corresponding treatment process according to the quality and types of the actual treated water source. For different kinds of sewage, such as industrial wastewater and biological wastewater, the treatment processes may vary greatly

because the universal energy mining plays a role in reducing the intensity of earthquake damage, using the distributed control system for hierarchical control and management, it also has high requirements for the industrial communication mode it relies on. In recent years, from the relatively popular Fieldbus to the relatively new industrial Ethernet, it has been applied on a large scale, and the effect has been increasingly improved. It is worth mentioning that in order to meet the application of remote monitoring and other special occasions, wireless communication technology has also been involved in the water treatment industry and achieved good results, which is undoubtedly an excellent supplement to wired communication

in the link of actuator, the application of frequency converter is becoming more and more common. When the frequency converter is applied to the loads of blower and water pump, it has multiple advantages. Compared with the regulation mode of valve and baffle, the frequency conversion speed regulation can make the speed regulation object run in the energy-saving state, and realize a lot of cost savings in principle; At the same time, the use of frequency converter also reduces the mechanical loss, reduces the impact of the actuator, and also plays a role in protecting electricity

long term outlook the industry has a solid foundation

from the above analysis, it can be seen that the water treatment industry is a typical industry for the systematic application of automation technology, and it also brings considerable opportunities for various automation products. Then, in the long run, can the development potential of this industry support it to become a powerful booster to drive the demand for automation products? We might as well analyze it from the following perspectives

first of all, as an industry, water treatment has certain ups and downs and periodicity, but in the long run, the social demand and growth for water purification, recycling and utilization are relatively stable. Especially with the continuous development of people's production and life, the requirements for water resources will also be upgraded, especially for the intelligence and safety of the water treatment industry, which brings a continuous potential space for the water treatment industry and related automation equipment

secondly, the direction of a series of national policies to the water treatment industry is undoubtedly positive and beneficial. In the near future, the basic investment of 4trillion yuan to expand domestic demand has shown its power to reverse the situation in most fields, and the water treatment industry, as a project-based investment industry, will also get a strong boost, especially the public industries such as domestic sewage treatment and urban water purification supply, will inevitably benefit from a considerable amount of infrastructure construction; In the long run, the national requirements for industrial environmental protection, energy conservation and other indicators are only increasing. It can be seen that some provinces and cities with concentrated industries have tried out a series of corresponding measures, which will naturally promote enterprises to pay more attention to industrial wastewater treatment and recycling
