waterworksMonitor the residual chlorine concentration in the factory water to ensure that there is still disinfection ability during pipeline transportation and prevent secondary pollution.

Water purification plantReal time control of residual chlorine in terminal water for direct drinking water and bottled water production, balancing disinfection effectiveness and taste.

sewage treatment plantMonitor the residual chlorine in the effluent of disinfection units (such as ultraviolet and chlorine disinfection) to ensure compliance with discharge standards and avoid affecting the receiving water body.

Municipal water supply networkInstall intermediate pump stations and end water intake points in the pipeline network, monitor the decay of residual chlorine, and adjust the disinfection strategy of the pipeline network in a timely manner.

Environmentally Friendly Water TreatmentUsed for centralized sewage treatment stations in industrial parks to monitor residual chlorine in external drainage, in compliance with environmental discharge standards.

Thermal heatingDetect residual chlorine in heating circulating water to prevent corrosion of the inner wall of the pipeline, the growth of microorganisms, and extend the service life of the pipeline network.

Hospital wastewater treatmentHospital wastewater contains a high amount of bacteria, and residual chlorine monitoring is necessary to ensure disinfection effectiveness and prevent the spread of bacteria.

Chemical wastewater treatmentPart of the chemical wastewater needs to be disinfected with chlorine before discharge, and the equipment can control the residual chlorine concentration to prevent excessive chlorine from interfering with subsequent treatment units.

River water quality monitoringInstalled at the mouth of river channels and around drinking water sources to monitor residual chlorine input from external sources and assess its impact on river ecology.

Smart rural water managementReal time monitoring of residual chlorine in peripheral water for rural centralized water supply projects to ensure the safety of drinking water for rural residents.

Sewage treatment plant customersPreviously, manual detection of residual chlorine required running three times a day. Now, the YST909B-CH980 equipment from Dalian Yister has been installed, and the data is transmitted in real-time to the central control, saving a lot of manpower and enabling timely detection of insufficient disinfectant dosage. ”

Hospital wastewater treatment clientsThe disinfection requirements for hospital wastewater are strict. The YST909B-CH980 equipment is monitored 24 hours a day. Once the residual chlorine does not meet the standard, an alarm will be triggered, so there is no need to worry about data being unqualified during environmental inspections. ”

Municipal pipeline network customersThe residual chlorine at the end of the pipeline network is prone to decay. After installing the YST909B-CH980 equipment, it can accurately determine which area needs chlorine replenishment, which is more scientific than adjusting based on experience before. ”

Thermal heating customersPoor control of residual chlorine in circulating water can corrode pipelines. After using the YST909B-CH980 equipment, the residual chlorine stabilized within a reasonable range and the number of pipeline repairs was significantly reduced. ”

industryMunicipal water supply network

demandThe municipal pipeline network in a certain city has a wide coverage area, and end users (such as suburban communities) often experience insufficient residual chlorine. It is necessary to accurately locate low residual chlorine areas.

SolutionA total of 12 Dalian Yister YST909B-CH980 equipment were installed at the pumping station in the middle of the pipeline network and the water inlet of suburban communities, and the data was transmitted in real-time to the central control platform of the Municipal Water Group.

effectThrough data analysis, three pipeline sections with severe residual chlorine decay were identified, and targeted chlorine replenishment points were added. The compliance rate of residual chlorine in the end water increased from 85% to 99%.

industryHospital wastewater treatment

demandThe wastewater treatment station of a tertiary hospital adopts sodium hypochlorite disinfection, and it is necessary to ensure that the residual chlorine in the discharged water meets the "Discharge Standards for Water Pollutants in Medical Institutions" (GB 18466-2005).

SolutionInstall Dalian Yister YST909B-CH980 equipment at the outlet of the disinfection unit, and set the alarm threshold (alarm when it is below 0.5mg/L or above 1.0mg/L).

effectThe equipment has been running for 1 year without exceeding or failing to meet residual chlorine standards. It has passed environmental testing multiple times and reduced the waste of sodium hypochlorite.

industryRiver water quality monitoring

demandThere are three industrial park sewage treatment plants around a certain river channel, and it is necessary to monitor whether the residual chlorine in the treated water has an impact on the river ecology.

SolutionInstall one Dalian Yister YST909B-CH980 equipment at each of the three sewage treatment plant inlet ports, and synchronize the data to the local environmental protection bureau monitoring platform.

effectDiscovered occasional excessive discharge of residual chlorine (>0.2mg/L) from one factory, promptly urged rectification to avoid toxic effects on river fish and shrimp.
