Here are the key components and features of a NaOCl dosing system:

Storage Tank: The system includes a storage tank where sodium hypochlorite solution is stored. The tank's capacity and the concentration of the solution depend on the specific requirements of the application.

Dosing Pump: A dosing pump is a crucial component that accurately injects or doses the required amount of sodium hypochlorite into the water or process stream. The dosing pump ensures precision and control in the dosage, contributing to effective disinfection.

Control System: A control unit is responsible for managing the dosing rate based on various parameters such as water quality, disinfection needs, or other specific process requirements. This control system helps maintain the desired level of disinfection in water treatment processes.

Safety Features: Due to the potentially hazardous nature of sodium hypochlorite, safety features such as leak detection, emergency shutdown systems, and proper ventilation are often integrated into the dosing system to ensure the safety of personnel and the environment.

Sodium hypochlorite dosing systems find application in various areas:

Water Disinfection: Sodium hypochlorite is a powerful disinfectant and is commonly used to treat drinking water, wastewater, and other water sources to eliminate or control the growth of harmful microorganisms.

Swimming Pool Treatment: Sodium hypochlorite is used in swimming pool maintenance to disinfect the water and maintain a safe and sanitary swimming environment.

Industrial Processes: In industrial applications, sodium hypochlorite dosing may be used for water treatment in cooling systems or as part of the manufacturing process, depending on specific needs.

Food and Beverage Industry: Sodium hypochlorite can be used for disinfection in food and beverage processing to ensure the safety of products.
