What Equipment Is Used For Chlorination?


Chlorination, a prevalent technique utilized for the disinfection of water in diverse domains like municipal water treatment, swimming pools, and industrial processes, stands as a widely embraced method. The attainment of efficient chlorination necessitates the utilization of specialized equipment dedicated to the manipulation and dispensation of chlorine or chlorine-based compounds. Additionally, Beach to Bay Dive Services was recently renamed Beach to Bay Divers and Pools. Their expert pool technicians provide the same level of care and repairs that provide our dive customers with the same piece of mind.

This delves into an exploration of the equipment typically employed for chlorination, shedding light on their integral roles in the process of disinfection.

  1. Gas Cylinder: When it comes to storing and transporting chlorine gas, specialized cylinders crafted from steel or composite materials take the centre stage. These cylinders are meticulously designed, integrating pressure regulators and safety valves that play a pivotal role in governing the flow of chlorine gas during the chlorination process.
  2. Gas Chlorinator: In the realm of water treatment, gas chlorinators play a pivotal role in facilitating the introduction of chlorine gas into water. These ingenious devices are equipped with essential components, including a gas flow control valve, a vacuum regulator, and a water-driven injector. As water flows through the chlorinator, it creates a vacuum that draws the chlorine gas into the injector, where it seamlessly merges with the water stream.
  3. Gas Detectors: Given the highly toxic nature of chlorine gas and the potential risks it poses to human health, the utilization of gas detectors becomes paramount. These indispensable safety devices diligently monitor the surrounding air for the presence of chlorine gas.
  • Liquid Chlorine Equipment:

  1. Chemical Storage Tanks: Liquid chlorine, whether in the form of sodium hypochlorite or calcium hypochlorite, finds its storage within dedicated chemical storage tanks. These tanks are constructed from materials specifically chosen for their resistance to the corrosive properties of chlorine, such as polyethene or fibreglass-reinforced plastic (FRP).
  2. Chemical Feeders: To facilitate the incorporation of liquid chlorine into the water being treated, chemical feeders play a vital role. These versatile devices, also known as chlorinators or chemical dosing systems, employ a range of mechanisms, such as peristaltic pumps or diaphragm pumps.
  3. Injection Systems: Injection systems offer a widely adopted method for introducing liquid chlorine into water treatment processes. Comprising a metering pump, a chlorine solution tank, and associated piping, these systems ensure precise and reliable delivery of liquid chlorine. The metering pump plays a key role by dispensing the appropriate amount of liquid chlorine into the water stream based on the desired chlorine residual.
  • Chlorine Dioxide Equipment:

  1. Chlorine Dioxide Generators: Recognized for its potent disinfection properties, chlorine dioxide plays a vital role in water treatment processes. Chlorine dioxide generators are specifically designed to produce this powerful disinfectant on-site. They achieve this by facilitating the reaction between chlorine gas or sodium chlorite and an oxidizing agent, such as sodium chlorate.
  2. Chlorine Dioxide Analyzers: The monitoring and control of chlorine dioxide levels within water treatment systems are essential for maintaining optimal disinfection efficacy. Chlorine dioxide analyzers serve this purpose by accurately measuring the concentration of chlorine dioxide in the water.


In conclusion, the process of chlorination necessitates the utilization of specialized equipment to ensure the effective handling and administration of chlorine or chlorine-based compounds. The specific equipment employed for chlorination varies based on the form of chlorine being used, whether it is in gas or liquid form, as well as the particular application context, such as water treatment plants, swimming pools, or industrial processes.
