Municipal wastewater treatment is the "lifeline" of urban operations, and its effectiveness directly impacts public health, water safety, and the ecological environment. Among numerous disinfection processes, hypochlorous acid disinfection, with its high efficiency, broad spectrum, and relative safety, has become a key industry choice. However, the storage, transportation, and use of traditional chlorine gas or finished sodium hypochlorite present safety risks and cost challenges. How can we achieve safe, efficient, and economically sustainable disinfection? Customized on-site hypochlorous acid generator solutions are becoming the intelligent answer for modern municipal wastewater treatment.
I. Why Choose On-Site Hypochlorous Acid Preparation?
Traditional disinfection methods relying on external supplies have significant drawbacks:
- Safety Risks: High risk of chlorine leakage; finished sodium hypochlorite is easily decomposed during storage, resulting in unstable concentrations.
- Operating Costs: High costs for transportation, storage, and safety protection; highly susceptible to market price fluctuations.
- Operational Complexity: Difficulty in controlling the precision of manual dosing; poor residual chlorine stability, potentially affecting disinfection effectiveness or causing secondary pollution.
In contrast, on-site electrolytic preparation of hypochlorous acid directly generates an effective chlorine solution within the equipment using salt (NaCl) and water, achieving:
- Intrinsically safe: Production is immediate, eliminating the need to store large quantities of hazardous chemicals.
- Controllable cost: Raw materials are only salt and electricity, significantly reducing and stabilizing operating costs.
- Precise dosing: Production can be adjusted in real-time as needed, linked online with system flow and water quality to ensure stable disinfection effects.
II. Customized Solutions: From "General" to "Specific"
Municipal wastewater treatment plants vary in scale, processes, water quality, and discharge standards. A single, universally applicable equipment cannot meet all needs. True value lies in deep customization.
1. Precise Scale Matching
Based on the wastewater treatment plant's capacity (tens of thousands to millions of tons per day), peak flow rate, and hydraulic retention time in the contact disinfection tank, we precisely calculate the required effective chlorine dosage, thereby determining the generator's rated output (e.g., kg Cl₂/h), avoiding underutilization or insufficient capacity.
2. Flexible Technology Integration
- Intelligent Control: Seamlessly integrates with the plant's PLC/SCADA system, receiving online signals from flow rate and residual chlorine (ORP) instruments to achieve fully automatic closed-loop control.
- Multiple Safety Measures: Built-in multiple safety monitoring and alarm modules for electrolyzer temperature, brine concentration, and rectifier protection ensure unattended safe operation.
- Redundant Design: For large or critical projects, a modular parallel design can be adopted to achieve non-stop maintenance and backup, ensuring production continuity.
3. Adaptable Process Fit
- Front-end Pretreatment: Provides chlorine production adjustment strategies for differences in influent water quality (e.g., high ammonia nitrogen concentration) to prevent waste caused by breakpoint chlorination.
- Back-end Effluent Guarantee: Strictly meets the fecal coliform count and other indicators of the "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants," and can be flexibly adjusted to cope with seasonal water quality changes or more stringent local standards.
- Byproduct Control: Effectively controls the risk of byproduct formation such as bromate and chlorite through advanced electrolysis technology and process parameter optimization.
4. Full Lifecycle Service
Customization extends beyond equipment to include services:
- Site Assessment and Design: Providing various solutions such as compact, containerized, or indoor installations to adapt to different site limitations.
- Energy Efficiency Optimization: Utilizing high-efficiency electrolyzers and low-energy DC power supplies to reduce power consumption per ton of water treated.
- Remote Operation and Maintenance Support: Leveraging an IoT platform for remote monitoring, fault diagnosis, and early warning, providing proactive maintenance.
III. Core Value: Dual Enhancement of Safety and Efficiency
Upgraded Production Safety
Transforming the externally dependent "hazardous materials transportation and storage"环节 into internally controllable "raw material salt solution management," significantly reducing the overall safety risk level of the plant area, simplifying safety assessments, environmental impact assessments, and daily safety management, and providing greater safety assurance for employees and the community.
Operating Efficiency and Economic Benefits
- Reduced Total Costs: Long-term operating costs are significantly lower than purchasing sodium hypochlorite or liquid chlorine, with a clear investment payback period.
- Improved Treatment Efficiency: Stable and precise disinfection effects ensure consistently compliant effluent quality, mitigating environmental risks.
- Optimized Management: Automated operation reduces manual intervention, while intelligent management improves overall operational efficiency.
Environmental and Social Benefits
On-site preparation reduces the carbon footprint related to transportation; hypochlorous acid decomposes in water, producing simple and environmentally friendly byproducts; ultimately, it provides a reliable barrier for downstream water bodies and public health, fulfilling corporate social responsibility.
