Automated disinfection control via a control system
Due to climate change, increasing droughts and a growing world population, clean drinking water is becoming increasingly scarce. Careful use of water and efficient treatment are therefore crucial in order to protect this resource.
Sustainable water management not only prevents water from being wasted but also reduces the amount of energy required for extraction and treatment, which in turn reduces CO₂ emissions. The protection and proper treatment of drinking water also preserves the natural water cycle, which is essential for the preservation of ecosystems and the long-term security of water supplies. Conversely, this helps to protect the environment and combat global water scarcity.
Ensuring the quality of drinking water by accurately measuring the chlorine concentration is crucial in order to avoid health risks and guarantee the disinfecting effect of the water. However, there are various challenges that can affect the precision and reliability of the measurements.
Challenges
In complex water supply networks, uneven chlorine distribution due to varying flow rates and system branches poses a significant challenge for accurate monitoring. These variations mean that chlorine concentrations can fluctuate widely across different areas, often making individual measurements unrepresentative of the overall network. Additionally, deposits and biofilms on sensors can lead to contamination, impacting the accuracy of readings and necessitating regular maintenance and calibration. Fluctuations in flow, pressure, temperature, and pH further complicate monitoring, as they affect chlorine stability and effectiveness, requiring real-time adjustments. Despite these difficulties, precise and continuous chlorine measurement is critical for maintaining water quality, regulatory compliance, and public health.
How can KROHNE provide support?
With its measuring devices, KROHNE offers an effective solution to the challenges of monitoring chlorine concentrations in complex drinking water networks. The measuring system is designed to perform precise and reliable measurements, even with uneven chlorine distribution or in networks with strongly fluctuating flow rates and pressure conditions.
Flushing and self-cleaning function
Thanks to the membrane-free sensor and automatic cleaning, the system minimises deposits, such as iron or manganese and significantly reduces maintenance requirements. This ensures continuous, reliable measurement even under difficult conditions. In addition, the system automatically compensates for temperature and pH fluctuations, ensuring measurement integrity in real time.
Dosing and monitoring the chlorine content
KROHNE's solutions thus help to ensure precise chlorine monitoring, comply with legal requirements and at the same time reduce operating costs through less maintenance and longer sensor life. This contributes to the safety and quality of the drinking water supply.
Automated disinfection control via a control system
It also measures the chlorine levels and transmits these automatically to the control system via a 4...20 mA output. This enables continuous and fully automatic monitoring of the chlorine analysis, which significantly reduces the manual effort. The automated measurement data transmission also ensures reliable and efficient control of the chlorine levels in the water network.
