Dalian Yister YST909B-CH980 model

Residual chlorine is a key indicator after water disinfection, which directly affects water quality safety and the effectiveness of preventing secondary pollution in water bodies. The YST909B-CH980 equipment launched by Dalian Yister, as the core equipment for real-time monitoring of residual chlorine content in water bodies, can continuously collect data and provide feedback results, providing key support for the disinfection control of water treatment processes. This equipment is our independently developed productOnline residual chlorine analyzer for water plantsRepresentative products widely used in various water related scenarios.

1、 Product Introduction

Our YST909B-CH980 equipment, based on specific detection principles such as colorimetric or electrode methods, can operate continuously on water treatment sites. It can automatically complete processes such as water sample collection, reagent addition (applicable to some working conditions), reaction detection, data calculation and output, without the need for frequent manual operations. The device can display the current residual chlorine concentration in water in real time and synchronize the data to the control system or monitoring platform through a signal transmission module. When the residual chlorine content exceeds the set range, it can also trigger an alarm function to help staff adjust the disinfection process in a timely manner and provide stable support for water quality control.

2、 Advantages and Characteristics

  1. High degree of automationOur YST909B-CH980 equipment can operate continuously for 24 hours, automatically completing the entire monitoring process without the need for manual sampling and testing, significantly reducing labor costs and operational deviations, and improving monitoring efficiency.

4、 Selection criteria

  1. Match water quality characteristicsSelect the specific configuration of the YST909B-CH980 equipment based on the water quality situation of the application scenario. For example, in wastewater treatment scenarios such as sewage plants and chemical wastewater treatment, if the water quality composition is complex, a configuration with strong anti-interference ability can be chosen; Water treatment plants and water purification plants have relatively clean water quality and can choose conventional configurations.

  1. Clearly define monitoring requirementsIf linkage control with disinfection equipment (such as chlorine dispensers) is required, a configuration that supports closed-loop control function should be selected; If used for remote supervision, it is necessary to confirm whether the device is compatible with the communication protocols of existing data platforms (such as MQTT, Modbus).

  1. Consider operation and maintenance conditionsFor scenarios such as rural water management and remote river monitoring, if the technical level of operation and maintenance personnel is limited, priority should be given to configurations that are maintenance free and have clear fault prompts; In scenarios such as chemical engineering and hospital wastewater, attention should be paid to the corrosion resistance of equipment pipeline materials (such as PTFE, 316L stainless steel).

  1. Adapt to installation environmentOutdoor installation requires the selection of high protection level configurations with low-temperature antifreeze or high-temperature heat dissipation functions; In scenarios where the flow rate of the pipeline is unstable, a stabilizing device should be used to ensure a constant flow rate of the detected water sample.

5、 Application industry

  1. sewage treatment plantInstall our YST909B-CH980 equipment at the effluent end of disinfection units (such as chlorine dioxide disinfection and sodium hypochlorite disinfection) to monitor the residual chlorine content in the effluent and ensure that the discharged residual chlorine meets the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" to avoid affecting the receiving water body.

  1. Water treatment plant/water purification plantDeploy this equipment at the outlet of the clean water tank and in front of the pipeline network to ensure that the residual chlorine in the factory water meets the standard, while ensuring that there is still sufficient residual chlorine in the water during transportation to inhibit bacterial growth and prevent secondary pollution.

  1. Municipal water supply networkInstall YST909B-CH980 equipment at intermediate pressure stations and end water monitoring points in the pipeline network to monitor the decay of residual chlorine in the pipeline network in real time, adjust the amount of chlorine replenishment along the line in a timely manner, and ensure the safety of residents' terminal water use.

  1. Environmentally Friendly Water TreatmentUsed for water quality monitoring of centralized sewage treatment facilities and ecological restoration projects in industrial parks, to control the effectiveness of disinfection processes and prevent secondary harm to the surrounding environment caused by treated water quality.

  • backgroundThe municipal water supply network in this city has a wide coverage area, and the residual chlorine in the peripheral water is severely attenuated, posing a risk of secondary pollution.

  • Application methodWe have installed a total of 20 YST909B-CH980 devices at the intermediate pressure stations in the pipeline network and the end water monitoring points in residential areas. The device data is wirelessly transmitted to the municipal water cloud platform through LoRa.

  • effectThe platform displays real-time residual chlorine data at each monitoring point. When the residual chlorine in the peripheral water is below 0.05mg/L, it automatically prompts the pressurization station to replenish chlorine; After implementation, the compliance rate of residual chlorine in peripheral water increased from 75% to 98%, and residents' satisfaction with water use significantly improved.

Case 2: A hospital wastewater treatment project

  • backgroundHospital wastewater contains a large amount of pathogens, and it is necessary to ensure that the residual chlorine after disinfection meets the "Discharge Standards for Water Pollutants in Medical Institutions" to avoid the discharge of pathogens.

  • Application methodInstall our YST909B-CH980 equipment at the outlet of the hospital wastewater disinfection tank, which is linked to the chlorination machine. When the residual chlorine is below 3mg/L, the chlorination amount will be automatically increased; When the concentration exceeds 5mg/L, reduce the amount of chlorine added.

  • effectThe residual chlorine remains stable within the standard range of 3-5mg/L, and the disinfection effect of wastewater meets the standard; At the same time, it avoids secondary pollution caused by excessive chlorine addition and reduces the waste of chlorine reagents.

Case 3: A rural centralized water supply project

  • backgroundThe rural area adopts centralized water supply from village and town water plants. Previously, it relied on manual testing of residual chlorine once a week, which could not detect water quality problems in a timely manner.

  • Application methodInstall our YST909B-CH980 equipment at the outlet of the clean water tank in the water plant, synchronize data to the county water management platform, and set up a local display screen in the water plant duty room.

  • effect: Realize real-time monitoring of residual chlorine. After a rainstorm, the equipment found that the residual chlorine dropped suddenly, and the staff adjusted the disinfection process in time to avoid unqualified water flowing into farmers; Rural residents' water hygiene and safety are effectively guaranteed.

We always focus on user needs and continuously optimize the performance of the YST909B-CH980 equipment. This equipment is also the core of our precise residual chlorine monitoring solution for various water related scenarios.
