"Smart Eyes" for Wastewater Plants: Data-Driven Purification for Every Drop

W771-CS4 Online Water Residual Chlorine Analyzer

Amid the hum of wastewater treatment plants, one critical challenge persists: How to accurately capture residual chlorine fluctuations during disinfection? Overdosing chlorine poisons microbes in bioreactors, forms carcinogenic byproducts, and corrodes equipment. Underdosing leaves pathogens intact, endangering discharge compliance and public health. Traditional manual sampling takes hours—too slow to respond to sudden pollution—turning process control into a game of guesswork. That’s until Germany’s RG CS4 residual chlorine sensor arrived, equipping disinfection processes with an industrial-grade, zero-latency data engine when paired with the W771 online analyzer!

The End of Disinfection Chaos: Core Pain Points Solved
Process Out-of-Control: Infrequent manual sampling leads to experience-based chlorination, wasting over millions in chemical costs yearly due to over/under-dosing.
Regulatory Pressure: GB 18466-2005 mandates residual chlorine at the contact tank outlet must strictly stay within 2~10mg/L—hard to guarantee with traditional testing.
Fragile Biochemical Systems: Chlorine shocks poison activated sludge, requiring weeks of recovery and causing ammonia nitrogen/COD violations.
Accelerated Equipment Corrosion: High residual chlorine speeds up pipeline rust, driving hidden maintenance costs skyward.

Three Precision Weapons of the CS4 Sensor
1. Conquers Harsh Wastewater Environments
2. Second-Speed Response & Closed-Loop Chlorine Control
3. Low-Maintenance & Long-Lasting Performance
