0.8% Sodium Hypochlorite Generator for Municipal Drinking Water Disinfection
1 Product Overview
The municipal drinking water dedicated low concentration sodium hypochlorite generator is a professional mild water disinfection equipment developed for civilian safe water supply scenarios. Different from high-strength industrial disinfection equipment, this system focuses on safe low-concentration chlorine production, with available chlorine strictly controlled within the safe range for drinking water. Using only refined salt and tap water as raw materials, it realizes green on-site electrolysis preparation of sodium hypochlorite, avoiding hidden dangers such as disinfectant deterioration, excessive chlorine residue and chemical leakage caused by stored commercial disinfectants. With high-precision dose control, low noise and low energy consumption design, the equipment maintains stable trace residual chlorine in water pipelines, inhibits microbial regrowth, and ensures long-term safe and qualified water supply for municipal water plants, residential secondary water supply and rural centralized water supply projects.
2 Technical Principle
This equipment adopts precision low-current constant-pressure brine electrolysis technology tailored for drinking water disinfection. Refined salt and raw water are automatically proportioned and dissolved into low-concentration dilute brine, which is precisely filtered to remove tiny impurities. The qualified brine is stably transported into a food-grade anti-corrosion electrolytic cell. Through low-current steady electrolysis, mild electrochemical reaction occurs to generate low-dose active sodium hypochlorite. The system intelligently adjusts electrolysis current and water inflow according to real-time water flow and pipeline residual chlorine data, maintaining uniform and safe low-concentration disinfectant output. The generated mild NaClO fully contacts with water body to realize efficient sterilization, and the residual chlorine will naturally attenuate within a safe range, achieving standard-compliant drinking water disinfection without secondary pollution.
3 Main Features
Safe Low-Concentration Mild Disinfection: Precisely controls available chlorine concentration, avoids excessive chlorine residue and peculiar smell in drinking water, fully compliant with international drinking water safety standards.
Green On-Site Preparation: Uses only salt and water as raw materials, no chemical additives, no stored hazardous disinfectants, safe and pollution-free for water supply systems.
Precision Residual Chlorine Locking: Linked with high-precision residual chlorine sensors to dynamically adjust dosing volume, ensuring stable trace residual chlorine in pipelines and preventing bacterial regrowth.
Fully Automatic Unattended Operation: Realizes automatic water feeding, salt dissolving, electrolysis and dosing, supporting 24-hour stable operation with low maintenance workload.
Low Energy Consumption & Low Noise: Optimized low-power electrolysis design, low operating noise and low power consumption, suitable for long-term continuous operation in residential and municipal facilities.
4 Core Advantages
Water Supply Safety Advantage: Mild low-concentration disinfection mode solves the pain points of strong irritation and excessive residue of traditional high-concentration disinfectants, ensuring drinking water taste and safety.
Stable Disinfection Effect: Real-time fresh NaClO generation avoids the problem of disinfectant failure and activity attenuation during long-term storage, maintaining consistent sterilization efficiency all year round.
Low Operating Cost: On-site self-production replaces purchased bottled disinfectants, greatly reducing long-term procurement, transportation and storage costs of water supply disinfection materials.
High Compatibility: Compact skid-mounted design, easy to install and transform, compatible with new and renovated municipal water plants and secondary water supply equipment rooms.
Standard Compliance: All operating indicators meet national and international drinking water disinfection specifications, easy for project acceptance and daily supervision.
