Role of Chlorine in Day to Day Life

While you might not realize it, the chemical chlorine and its compounds are part of almost everyone's daily life. The water you drink, the food you eat, the medicine you take, the apparels you clean, the swimming pool you swim in, the car you drive, and thousands of other products are sanitised or manufactured with chlorine.

Chlorine is used in many industrial processes, including industries where plastics, vinyl, and nylon are made as well as pharmaceuticals and the food/beverage industry, too. The electronics industry depends on chlorine in the production of microprocessors and computers. Chlorine is used in the manufacture of gasoline additives, brake fluid, and antifreeze, as well as popular metals such as titanium, magnesium, and aluminium.

How can something so common and useful also be so dangerous and potentially deadly when used improperly? Chlorine gas has an intoxicating effect and appears green-yellow at room temperature. It is also water-soluble. At 0.3 to 0.5 parts per million (ppm), you can start to detect its smell, and trouble soon follows in higher concentrations.

Chlorine gas may have a burning effect on the eyes, nose, and throat which may cause bronchial inflammation, respiratory tract damage, and death. Chlorine is denser than air, which implies that it remains near the ground and exposure victims need to be moved away from the contaminated environment. In World War I, chlorine gas also was used as a weapon which caused mass destruction on U.S. soldiers.

Clean Water Treatment 

Chlorine is used as a cleaning agent to treat drinking water to destroy bacteria and other harmful micro-organisms. It also restricts the growth of algae or slime and helps improve the taste and smell of fresh water. Chlorinating basins and well sites have small infrastructure enclosing chlorine storage tanks with mixing systems. Fans are provided for a ventilation system, with gas detectors installed for monitoring and alarm purposes in case of a system leak. Handy gas detectors often are carried into these confined space areas.

Sewage Wastewater 

For neutralization of effluent, a complete chlorination system is used at waste treatment facilities. Toxic gas detectors are used to detect chlorine gas at this location - the chlorine tanks, the chlorine dosing pump, the chlorine mixer, and the sampling area. In open settling pond areas, portable gas detectors are carried to warn workers of excessively high concentrations of gas.

In the workplace, both handy gas detectors and fixed gas detection systems are installed to help protect workers from chlorine. Depending on the type of workplace hazard, one or both types of gas detectors may be used. From the above description, it is clear the use of chlorine is prevalent in so many industries and it is helpful if we have a broader understanding of its applications in various industries before developing a chlorine gas safety program and determining the requirements for portable and/or fixed gas detectors in any plant.

The Biggest Contribution of chlorine to Humanity

Chlorine was discovered in 1774 by carl Whihelm Scheele but its name was given by Humphry Davy in 1810. The name Chlorine is derived from colour, meaning green, referring to the colour of the gas. Chlorine has become an important element nowadays and its application are enormously more than even you can imagine.

Chlorine Application

Chlorine is an important chemical which is mainly used for water purification, bleach, in mustard gas and in disinfectants.chlorine is involved in bleaching wood pulp for paper making, bleach is also used industrially to remove link from recycling paper. Chlorine chemistry is critical for manufacturing medicines we depend on, it is generally used to make medicines which lower cholesterol, control arthritis pain and relieve allergy symptoms. Another major use of chlorine is in organic chemistry. It is used as an oxidising agent and in substitution reactions. 85% of pharmaceuticals company use chlorine or its compounds at some stage in their manufacture.

 The contribution made by chlorine

Since it's discovery chlorine found its application in many fields, as discussed earlier the application of chlorine, one thing is sure that its application is getting widened day by day. In the past chlorine was commonly used to make chloroform (an anaesthetic) and carbon tetrachloride (a dry-cleaning solvent). However, both of these chemicals are now strictly controlled as they can cause liver damage and results in severe health problems.

Chlorine was mainly used in human history to remove various bacterias and viruses from water and it's termed later as chlorination of water which is mostly use till now to make water potable. Chlorine so far finds it's application in many fields, from pharmaceutical to the food industry and now scientist is working in making fast processor using chlorine as one of the base material.

Know More about Gas Chlorination

Chlorine is broadly used as the main disinfecting ingredient for gas chlorination treatments in the water industry. Chlorine acts as a fast oxidizing agent treat organic taste and odour and produce a free-chlorine residual. 

Purpose of Chlorination 

  • Chlorination is basically used for disinfection and oxidation in water treatment. 
  • Chlorine can directly destroy the bacterial cell. 
  • Chlorine deactivates the enzymes which enable the cells to use food, thus starving the organisms. 

Elemental Chlorine 

Elemental chlorine is liquid or gaseous in form. 

Chlorine gas can be compressed to a point where it liquifies. Cylinders contain both liquid chlorine 

(about 85%) and gas chlorine (about 15%). In its gaseous form, it is 2.5 times heavier than air. 

Liquid chlorine rapidly vaporizes to gas when unpressurized.One volume of liquid chlorine provides about 450 volumes of gas chlorine. 

The gas chlorination has proven a safe and potent way to disinfect water supplies. Chlorine gas is not considered to be harmful, but it is a respiratory, eye and skin irritant. Chlorine gas can cause breathing difficulties and even suffocation in very high concentrations. 

Chlorine is not explosive, but it can support combustion. All forms of chlorine must be used and handled with proper knowledge, care, and respect in order to eliminate the potential for unsafe conditions. 


The disinfection of potable water is one of the most standard chlorine applications. In addition to being a potent but economical disinfectant. Gas chlorine is also used to disinfect treated wastewater and reclaimed water. 

Many industries also use gas chlorine for various applications, including cooling water and intakes, aluminium or gold fluxing, pulp and paper, food and beverage, rubber glove manufacturing, flour bleaching, and more.

Benefits of Chlorine as a disinfectant


Chlorine is one of the most frequently used disinfectants for water disinfection. Chlorine can be used for the deactivation of most microorganisms and it is relatively cheap. 

Chlorine as a disinfectant 

Chlorine is one of the most broadly used disinfectants. Chlorine is very relevant and powerful for the deactivation of pathogenic microorganisms. It can be easily applied, measures and controlled. It is really persistent and comparatively low cost. 

Chlorine has been used for many applications, such as the deactivation of pathogens in drinking water, swimming pool water, and wastewater, for the disinfection of household areas and for textile bleaching. 

How does chlorine disinfection work? 

Chlorine destroys pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules. Disinfectants are used for this reason consist of chlorine compounds which can exchange atoms with other compounds, such as enzymes in bacteria and other cells. While enzymes come in contact with chlorine, one or more of the hydrogen atoms in the molecule are changed by, it causes the entire molecule to change shape or fall apart. whereas enzymes do not function properly, a cell or bacterium will die. 

underchloric acid and hypochlorite ions will form free chlorine when bound together. This results in disinfection. Both substances have very distinctive behaviour. underchloric acid is more sensitive and is a powerful disinfectant than hypochlorite. underchloric acid is separate into hydrochloric acid (HCl) and atomic oxygen (O). The oxygen atom is a powerful disinfectant. 

The disinfecting properties of chlorine in water build on the oxidizing power of the free oxygen atoms and on chlorine substitution reactions. 

By nature, the cell wall of pathogenic microorganisms is negatively charged. so, it can be penetrated by the neutral underchloric acid, rather than by the negatively charged hypochlorite ion. Underchloric acid can pierce slime layers, cell walls and protective layers of microorganisms and effectively kills pathogens as a result. The micro organisms will either die or suffer from reproductive failure. 

The efficiency of disinfection is controlled by the pH of the water. disinfection on chlorine will take place best when the pH is between 5,5 and 7,5. under chloric acid (HOCl) reacts faster than hypochlorite ions (OCl-); it is 80-100% more effective. The quantity of underchloric acid will decrease when the pH value is higher. 

With a pH value of 6, the level of underchloric acid is 80% when the concentration of hypochlorite ions is 20%. 

while the pH value is 8, this is the other way around. 

while the pH value is 7,5, concentrations of underchloric acid and hypochlorite ions are equally high. 

Which factors determine the effectivity of chlorine disinfection? 

Factors which decide chlorine disinfection effectivity: 

The factors are Chlorine concentrations, contact time, temperature, pH, number and types of microorganisms, concentrations of organic matter in the water. 

Disinfection time for some different types of pathogenic microorganisms with chlorinated water, containing a chlorine concentration of 1 mg/L (1 ppm) when pH = 7,5 and T = 25 °C 

Disinfection time of fecal pollutants with chlorinated water 

E. coli 0157 H7 bacterium < 1 minute 

Hepatitis A virus about 16 minutes 

Giardia parasite about 45 minutes 

Cryptosporidium about 9600 minutes (6,7 days)

Public Water Treatment through Chlorination

The chlorination of public drinking water has been hailed as one of the most outstanding advancements in public health of the last century. Nowadays, the majority of municipal water supplies in the developed world are disinfected using chlorine-based solutions, either alone or in combination with others. Long has chlorination of drinking water proved to be a safe, effective, economical and widely applicable water treatment method. 

How Chlorine Works 

Chlorine exists in several forms, but for the purposes of water treatment, it’s most commonly used as either compressed gas, as liquid sodium hypochlorite (bleach), as solid calcium hypochlorite, or as a tablet of sodium dichloroisocyanurate (NaDCC). 

When any of these forms is added to water, it commonly reacts by forming what is called free available chlorine (FAC). FAC is a balance of differing levels of hypochlorous acid and hypochlorite ion depending on the pH level of the water. 

As these FAC agents come into contact with waterborne microorganisms, they attack the pathogens at various levels, either killing them or rendering them incapable of reproducing, thus providing you with microbiologically safe drinking water. 

Chlorine’s Advantages 

The scientists had discovered that chlorine served as a suitable protection against waterborne microorganisms. Now that benefits combine with chlorine’s many other advantages to make it a viable solution to combating waterborne disease around the world. 

Potent Disinfectant: 

Chlorine minimise the threat of nearly all types of waterborne microorganisms (the most notable exceptions being Cryptosporidium and Mycobacteria), making it a highly effective and efficient way to treat drinking water. 

Additionally, it can neutralize the foul tastes and odors from organic substances, such as decaying plant matter and sulfides. Chlorine inhibits mold and algae growth, and oxidizes inorganic chemicals like iron and manganese, making it a versatile disinfectant. 

Safe and Simple to Use: 

Chlorine is very well studied, which means science tells us how to use chlorine effectively and safely. Chlorine takes a very small amount of chlorine to kill the pathogens, a level that is still very safe for human consumption. 

Chlorine is simple to use nature also increases its safety. As water treatment, it requires only three steps: add the dose, agitate the water, wait 30 minutes. Science tells us the correct dosage needed, so we simply increase that dose based on the number of liters we are treating. 

Residual Effects: 

Chlorine continues to disinfect after its initial treatment. Chlorine has residual effects, This means it continues to work until all the chlorine molecules have been exhausted. So, How long that takes depends on storage conditions (light, heat, etc.). Although chlorine will continue to kill any microbes introduced into the treated water until all the chlorine molecules are used up. This chlorine residual provides extra protection against re-contamination. 

Efficient for Treating Large Volumes: 

The residual qualities make chlorine great for treating large volumes of water as well. The larger the volume or the farther that water must travel to reach its end-user, the more likely it is to be re-contaminated. Chlorine’s residual qualities help safely against this threat. 

Additionally, a relatively small amount of chlorine goes a long way when compared to the size of the filter that would be required to treat vast amounts of water without quickly clogging. So, chlorine is a very efficient way to treat water for thousands of people. 

Low Cost: 

However its cost varies with circumstances, chlorine treatment is still overall one of the least expensive treatment methods available, this is one reason it’s by far the most commonly used water disinfection method in the world. The resources chlorine requires are widely available and low-cost, and the tools needed to use it are elementary. so, chlorine lacks many of the expensive maintenance, repair, and operating costs associated with other types of water treatment methods. 

Chlorine’s effective power is an advantage as well. In a minimal of 30 minutes, entire community tanks of contaminated water can be rendered drinkable using considerably little of the resource.

Things you need to know about Chlorine Leak Detectors

Water treatment and many other technical processes frequently require the use of oxidising gases such as chlorine or chlorine dioxide. These gases are highly toxic and corrosive. Therefore special precautions have to be taken in areas where such gases are used. The Air is contaminated with oxidising gases will endanger plant personnel and equipment. If employees are revealed to low concentrations of these gases for extended periods, the safety limit will be reached. Higher concentrations gases will affect the respiratory system of the personnel and corrode machines resulting in costly repairs. 

The gas leak detector monitors the contents of oxidising gases in the air, indicates leaks and warns the personnel in plants where chlorine or chlorine dioxide are generated, stored or metered. The unit will initiate a visual and audible alarm if the MAK value is exceeded. The MAK value is the maximum permissible gas concentration in the air of an area where people are working. MAK values are toxicological limit values. 

Description of Operation 

The gas leak detector consists of two crucial items; the detector cell assembly which is connected by means of a coaxial cable to a control box. The detector cell includes two platinum electrodes wrapped by a porous wick. The electrode is partly immersed into an electrolyte reservoir attached and thus kept constantly moist. One stuffing of the electrolyte reservoir is sufficient for approximately one year of continuous operation. The chlorine dioxide gas or chlorine gas be should present in the surrounding air, an electrochemical reaction by depolarisation will take place on the electrode; the electric current produced is proportionate to the gas concentration in the air. 

An increase in the chlorine gas concentration is indicated on the electronic control box which is equipped with an indicator of 0...5 ppm Cl2. The desired alarm level is set by means of a potentiometer having a range between 0...5 ppm Cl2 If two alarm levels are required an amplifier with two operational set points will be used. 

When the gas concentration in the air exceeds the preset value, the leak detector will release a visual and audible alarm and operate an alarm relay. This alarm relay provides a voltage-free single pole double throw contact for use by the customer to actuate safety devices such as a solenoid valve in the gas line or a neutralisation system. 

When the gas concentration drops below the preset limit, the alarm contact will move back to its former position. If the preset value is exceeded for more than 10 seconds, the light emitting diode alarm horn will light and a further relay will be energised. The alarm horn is fixed to the potential free output of this relay. The relay will remain energised until it is reset either by means of the push button on the control box or by an external push button in the customer's control centre. After having stopped the alarm and after the gas concentration has dropped below the preset limit, the contact will automatically be in operating condition again. 

The real functioning of the leak detector may be checked at any time by operating a test button. The test button is provided as a push button with a built-in light emitting diode. 

The combined test button and cell failure alarm light will flash at the following conditions: Electrolyte reservoir empty 
  • Detector cell dry 
  • The cable between cell and control box interrupted 
An internal circuit board provides for the continuous output signal of 4... 20 mA, 300 Ohms, corresponding to a gas concentration of 0...5 ppm C12. Industrial Devices manufactures also a chlorine gas generator capable of generating adjustable chlorine gas concentrations in the air. This unit is a very practical accessory item for the physicochemical calibration of the leak detector. The detector cell is placed close to the place where the air is to be monitored. As chlorine level is heavier than air, the cell is mounted approximately 350 mm from the floor. 

The ambient temperature should be in the range between -10°C and +50°C. The control box containing the electronic amplifier, the alarm horn and other alarm devices connected to the alarm output should preferably be installed in a chlorine-free room. The distance between the control box and the detector cell may be adapted to the local requirements. While using a screened cable this distance may be up to 100 m. If the distances are more than 2 m between cell and control box, a connection box must be used.
