Sodium Hypochlorite Dosing Systems
Sodium Hypochlorite Dosing Systems
How the System Works
Sodium hypochlorite is a widely used, safe-to-handle disinfectant for municipal and industrial water. A dedicated dosing system stores the solution in a protected tank and feeds it through a diaphragm pump whose rate is trimmed by a residual-chlorine or ORP analyser. This maintains a stable disinfectant residual, destroys pathogens and prevents biofilm, while avoiding the hazards of gas chlorine.
Standard Configuration
- UV-stable PE/PP day tank with level switch
- Diaphragm metering pump, PVDF head, manual + automatic stroke
- Online residual chlorine or ORP analyser
- Ventilated, spill-contained cabinet
- PLC control cabinet with touchscreen HMI
Key Features
- Closed-loop residual control avoids over/under-dosing
- Degassing valve protects the pump from gas lock
- Tank bund and ventilation for safe hypochlorite storage
- Chemical-resistant wetted parts (PVDF, PP, EPDM)
- Remote alarm and data logging via Modbus
Typical Applications
- Drinking-water and spring-water disinfection
- Wastewater effluent disinfection
- Swimming-pool and leisure-water treatment
- Food and beverage process-water sanitation
- Cooling-tower microbial control (secondary biocide)
