Stable Disinfection Guarantee for Rural Large-Scale Water Supply Projects

DABECO W510-CCF1.0 Free Chlorine Monitoring Analyzer

A township’s large-scale water supply project serves 15 administrative villages with groundwater, adopting chlorine dioxide disinfection and complying with the Rural Drinking Water Safety and Sanitation Evaluation Index System. It requires a water quality compliance rate of no less than 90% and residual chlorine controlled at 0.05-0.5mg/L. Rural water supply fluctuates significantly (peak flow differs by up to 4 times), and maintenance personnel have limited professional skills, creating an urgent need for low-maintenance, high-reliability monitoring equipment.

The project installed W510 instrument-CCF1.0 free chlorine sensor at the clear water tank outlet. Their flow adaptation range of 5-100L/h (flow velocity 5-100cm/s, flow impact error ≤±3%) perfectly matches large rural water supply fluctuations. The membrane-free and consumable-free design (service life ≥5 years) requires only 2 calibrations per year (DPD method, calibration time ≤5 minutes), reducing maintenance workload by 85% compared to traditional membrane sensors. For unstable rural power grids, the 9-30VDC wide-voltage power supply (ripple tolerance ≤10%) ensures continuous stable operation. Paired with the Dabeco W510 online monitoring instrument, it achieves real-time water quality monitoring.
