Online-chlorination System

An ”onsite chlorination sodium hypochlorite dosing system,” it generally refers to Electrochlorination, is a process that uses electricity to generate active chlorine 5-7g/l from salt water. This is accomplished by electrolyzing a brine solution, which usually consists of sodium chloride (salt) dissolved in water. In the electrochlorination process, an electric current is passed through an electrolytic cell containing a salt water solution. The electrolytic cell is equipped with an anode and a cathode made of different materials. When current flows, chloride ions (Cl-) are oxidized at the anode, releasing chlorine gas (Cl2). At the same time, hydrogen gas (H2) is produced at the cathode due to the reduction of water molecules, the hydrogen gas will be diluted to the lowest value and then be discharged to atmosphere. YANTAI JIETONGs Sodium hypochlorite active chlorine produced through electrochlorination can be used in a variety of applications, including water disinfection, swimming pool sanitation, especially widely used city tap water disinfection. It is highly effective at killing bacteria, viruses and other microorganisms, making it a popular method for water treatment and disinfection. One of the advantages of electrochlorination is that it eliminates the need to store and handle hazardous chemicals, such as chlorine gas or liquid chlorine. Instead, chlorine is produced on-site, providing a safer and more convenient solution for disinfection purposes. It’s important to note that electrochlorination is only one method of producing chlorine; other methods include using chlorine bottles, liquid chlorine, or compounds that release chlorine when added to water. The choice of method depends on the specific application and user requirements.


The dosing system generally consists of the following components:

  1. Salt water electrolysis system: salt is dissolved in water to make brine water to go to the electrolysis cell and to produce 6-8g/l (active chlorine) sodium hypochlorite, the produced sodium hypochlorite will go to the storage tank.
  2. Storage tanks: Sodium hypochlorite solutions are stored in tanks usually made of HDPE (high-density polyethylene) or similar materials to prevent degradation or leakage.
  3. Dosing Pumps: dosing pumps, typically made of chemically resistant materials such as PVC or stainless steel, are used to accurately and continuously inject the required amount of sodium hypochlorite solution into a water stream. Pumps can be controlled by flow meters or feedback loops for precise dosing.
  4. Control Panel: The control panel is used to monitor and control the dosing system. It may include features such as adjustable dosing rates, timers, alarms, and safety shutdown mechanisms.
  5. Injection point: The dosing system is connected to the water pipe and usually has an injection point where the sodium hypochlorite solution is introduced into the water stream.

The purpose of this system is to quickly and effectively disinfect water by adding controlled amounts of sodium hypochlorite, which in turn releases chlorine. Chlorine is a powerful disinfectant that kills pathogens, bacteria, and other harmful microorganisms present in water. Please note that the specific design and setup of a sodium hypochlorite dosing system may vary depending on the application and facility requirements.
