Working Principle of Chlorination Systems
Chlorination Machines deliver precise chemical disinfection for water treatment plants, eliminating pathogens through controlled chlorine dosing. Here's how they safeguard water quality:
1. Automated Dosing: Proportional pumps inject liquid sodium hypochlorite (NaOCl) or chlorine gas (Cl₂) based on real-time flow and residual chlorine levels.
2. Contact Time Optimization: Water-chlorine mixing in contact chambers ensures >99.99% pathogen kill (CT value compliance).
3. Residual Maintenance: Sustains 0.2–2.0 ppm residual chlorine in distribution systems to prevent recontamination.
4. Safety Integration: Leak detectors, scrubbers, and fail-safe valves neutralize risks during gas/liquid handling.
Key Advantages of Chlorination Systems
- Unmatched Pathogen Control: Meets WHO/EPA standards for E. coli, Legionella, and virus inactivation.
- Precision Dosing: ±0.1 ppm accuracy via closed-loop control with ORP/amperometric sensors.
- Dual-Format Flexibility: Compatible with liquid NaOCl (12.5%) or gas Cl₂ (100-lb cylinders).
- Zero Downtime: Redundant pumps and automated switchovers ensure 24/7 operation.
- Corrosion-Resistant Build: FRP/SS316L tanks, Hastelloy valves, and PTFE-lined tubing.
