Types of Chlorine Injection Systems

A Chlorine Injection System enhances the quality and safety of water through proper chlorine dosing. Chlorine can be applied in different ways, and several types of chlorine injection systems exist based on this fact.

• Chlorine Gas Disinfection System

  This is an auto-control injection system that uses chlorine gas as a raw material. The system comprises a vacuum regulator, a chlorinator, a gas scrubber, a pipeline system, etc. It stores the chlorine in a liquefied gas tank and vaporizes it in the vaporizer. A vacuum creates a negative pressure to inject the chlorine gas into the water through a solution pipeline. This control system precisely meters the quantity of chlorine gas. It also has an alarm for the gas leakage in the storage tank, which secures the user's safety.

• Chlorine Dosing System

  A Chlorine Dosing System delivers chlorine in a solution form (Liquid Chlorine) or as solid Chlorine in the form of tablets or pellets. If the system uses liquid Chlorine, a storage tank, a dosing pump, and a flow meter are necessary. The flow meter measures the quantity of chlorine flowing in the pipeline. The dosing pump meters the amount of chlorine in the water. If the system uses solid Chlorine, there should be a dissolver and a tablet feeder. The tablet feeder will feed the tablets in the water, while the dissolver will help dissolve the tablets.

• Electrochlorination System

  This system produces chlorine on-site through the electrolysis of saltwater (or saline water). It has a feed unit (brine) and an electrolysis unit. The feed unit will prepare the saline solution. It will make a concentration of saline water and pump it into the electrolysis unit. The electrolysis unit will generate chlorine and other by-products. A neutralization tank or a separation unit will neutralize or separate the by-products, respectively. The main advantage of this system is that it does not have to store chlorine, which reduces the risk associated with hazardous chemical storage.

Specification and maintenance of Chlorine Injection Systems

The following specifications apply to the maintenance of chlorine systems.

• Operating Pressure

  Chlorine gas should be kept under pressure between 0.3 and 1.3 bars (30 to 130 kPa) as this pressure will ensure that it remains in a gaseous state so that accurate dosing can occur. Regular monitoring and adjustment as required of the cylinder valve and regulator must also take place to maintain this level of pressure.

• Operating temperature

  Chlorine gas should be kept at a temperature between -15 and 70 degrees Celsius as this temperature range will ensure that it remains stable. Storing chlorine cylinders in a cool, dry place away from direct sunlight, heat sources, or any other material that could react with chlorine is essential. Ideally, they should be kept at ambient temperatures but within the stipulation of -15 and 70 degrees Celsius.

• Maintenance

  Regular inspections of the chlorine gas system including the piping, valves, and fittings should be conducted to identify leaks promptly. All of the components should be integrally checked for signs of wear and tear, corrosion, loosening of the threaded fittings, and any other indication of damage that could compromise the integrity of the system. For valves, operators should be aware of any audible hissing sounds or the smell of chlorine, both of which indicate leaks. Any leaks should be identified and rectified by professionals with the required qualifications and experience. Chlorine gas systems should be used in well-ventilated facilities protected from the wind and precipitation. Chlorine gas is toxic, and inhalation can cause serious health effects. In the case of on-site exposure to chlorine, immediate medical assistance should be sought, and the individual should be evacuated from the area of exposure. In most cases, PPE for chlorine must be used by operators, which may include but not be limited to self-contained breathing apparatus (SCBA) and full face SCBA firefighting and rescue anti-chlorine gas masks. Environmental protection measures for chlorine gas involve ensuring that the gas cannot enter any water bodies to prevent chemical pollution. Spills should be promptly and carefully cleaned with the help of an expert, and the solid should be disposed of in a hazardous waste landfill.

Chlorine injection system Q&A

Q1: What are the different types of chlorine injection systems?

A1: The two main types of chlorine injection systems are gas chlorination and hypochlorite solutions. In gas chlorination, a chlorinator feeds chlorine gas into a solution using a suction line. This is a common method because gaseous chlorine is 2.5 times more potent than sodium hypochlorite. Hypochlorite solutions are less effective, so larger quantities are needed to achieve the desired levels.

Q2: How big is the chlorine injection market?

A2: The global gas chlorination market was valued at more than $350 million in 2023 and is forecast to reach almost $700 million by 2030.

Q3: How does a chlorine injector work?

A3: The chlorine injector works using the venturi effect. The injector has a constricted throat which increases the water velocity and creates a drop in pressure. The drop in pressure creates a suction force that pulls the chlorine from the container or solution into the pipeline where the water is flowing.

Q4: What are the benefits of a chlorine injection system?

A4: The system prevents bacteria and viruses from growing in a water supply. It keeps the water safe for drinking, swimming, or any other use. Another benefit is that it can disinfect large amounts of water very quickly.
