User: Natural Gas Processing Plant in Changqing Oilfield As the largest natural gas ethane recovery unit in China, a natural gas processing plant in Changqing Oilfield is a key project of CNPC to improve quality and efficiency. To achieve the supply of raw materials for the process of producing ethylene from ethane as soon as possible, the project not only adopts the international advanced "refrigerant refrigeration + expansion refrigeration + double gas overcooling + low temperature distillation" ethane recovery main body technology, but also adopts advanced technology in engineering design and construction.CNPC fully leverages its overall advantage and uses, the international advanced SP3D three-dimensional collaborative design platform, "and full life cycledigital factory" mode, to achieve digital and intelligent management of the entire process of design, procurement, construction, operation and maintenance.

During the "14th Five-Year Plan" period, a gas production plant in Changqing Oilfield fully integrated carbon peaking and carbon neutrality into its strategic development plan, and proposed an overall goal of achieving a clean energy utilization rate of no less than 25% by 2025. Currently, various "green" new projects are accelerating their construction, and new momentum is accelerating and gathering momentum.

A sewage treatment plant, located in an industrial park in northern Vietnam, which had a daily treatment capacity of 200 cubic meters and was required to meet the 2011/BTNMT Class A standard, in order to ensure the highest efficiency of wastewater treatment, customers in the factory integrated the advanced monitoring system, continuously measure and analyze of the following key parameters to ensure the best performance:

The sewage treatment plant located in a township in Tonglu County, Zhejiang Province discharges water continuously from its sewage outlet into the river, and the nature of the sewage discharge belongs to the municipal category. The sewage outlet is connected to the water channel through a pipeline, and then the treated sewage is discharged to a certain river. The sewage treatment plant has a designed sewage discharge capacity of 500 tons/day and is mainly responsible for treating domestic sewage from residents of a township in Tonglu County.

Some sewage treatment center in Beijing is one of the infrastructures constructed to solve the sewage treatment problems in the town and its surrounding areas. It was formally completed and put into use in June 2009. At present, the central area of the town adopts a combined drainage system without sewage treatment facilities. The sewage is not treated and discharged into a river through the existing combined pipeline, causing great pollution to the existing water situation. With the further acceleration of urban construction, the population of the town is developing rapidly, and the amount of sewage is increasing day by day. In addition, in order to protect the city's water sources, as an important part of urban infrastructure, it’s necessary to construct sewage treatment plant in this town. A new artificial wetland will be built around the sewage treatment plant, and the treated water will be used as the source of the artificial wetland or discharged into a certain river. The project scale is 20000 m3/d in the near future and 30000 m3/d in the long term.

A Russian industrial enterprise that mainly produces food and feed products, and also focuses on the application of sterile and non-sterile fermentation processes in the field of biotechnology, as well as the development and implementation of large-scale and non-conventional projects related to environmental protection.In pursuit of environmentally friendly practices, the Russian conglomerate uses advanced biotechnological methods in its production processes. A key aspect of their operations involves aseptic fermentation, which requires precise monitoring and control of key parameters such as pH and dissolved oxygen, which significantly impact fermentation efficiency and product quality.

A high-temperature fermentation manufacturing company in India monitors the liquid in the fermentation to promote the growth of microorganisms in the most suitable pH range and ultimately synthesize target metabolites. Therefore, the pH value needs to be strictly controlled during the fermentation process. Dissolved oxygen is an important parameter in microbial fermentation control, which directly affects the stability and production cost of fermentation production.On the one hand, controlling the dissolved oxygen in fermentation liquid can improve the growth and metabolism environment of microorganisms and effectively promote the accumulation of beneficial metabolites during the fermentation process. On the other hand, it can also save energy and reduce consumption, which is of great significance to the production of enterprises.Especially for high-density fermentation, improving the dissolved oxygen condition of fermentation liquid is the key factor to promote product synthesis.Therefore, fast and accurate online monitoring of numerical changes and timely adjustment of numerical values are a key factors for the final success of fermentation.

A hydroponic vegetable company in Brazil who detects the pH and conductivity of the solution in the peristaltic pump to ensure that the concentration of chemical substances required during vegetable growth is within the appropriate range.For hydroponic vegetables, the suitable pH range is usually between 5.5-6.5, pH value that is too low will cause poor dissolution of metal ions in the nutrient solution, affecting the absorption of nutrients by vegetables;

This Malaysian user is mainly engaged in the aquaculture industry. An indoor fish pond is an aquaculture facility that allows fish to be grown indoors. This facility usually consists of a large cement or plastic pool that can hold a certain amount of water and is equipped with appropriate ventilation and lighting systems. In addition to these infrastructures, indoor fish ponds pay more attention to water quality management and require regular testing. and adjust water quality to ensure the stability of the fish growth environment.

Aquaculture, is divided into freshwater aquaculture and mariculture, involves automated controlled farming through real-time water quality monitoring. It includes all cultivation of aquatic organisms such as fish, shellfish, crustaceans and seaweed.
