Chlorine (Calcium Hypochlorite) is a highly potent oxidizing and disinfecting chemical. Its primary purpose is for disinfection and bleaching. In Vietnam, it is commonly used in swimming pool water treatment, aquaculture, and potable water treatment.
Overview of Chlorine (Calcium Hypochlorite)
Chlorine, also known as Clorin or Chlorine 70%, is a strong oxidizing compound offering significant benefits, especially in the field of water treatment.
On the market today, Chlorine is typically available in two forms:
Chlorine dissolves well in water, forming hydrochloric acid (HCl) and hypochlorous acid (HOCl). Hypochlorous acid (HOCl) will further ionize to create hypochlorite ions (OCl⁻).
Disinfection mechanism of Chlorine
Chlorine, in its various forms such as Ca(OCl)₂, NaOCl, and Cl₂, is a potent oxidizer. When it reacts with water, it produces large amounts of hypochlorous acid (HOCl) and hypochlorite ions (OCl⁻). Hypochlorous acid then ionizes to form more OCl⁻ ions. Both HOCl and OCl⁻ work by breaking down the cell walls of bacteria and infiltrating their structure, ultimately destroying them by disrupting their molecular composition.
This powerful disinfecting action is why chlorine is widely used in water treatment processes, efficiently eliminating harmful bacteria that pose health risks. It’s an essential compound in many industrial processes.
Applications of Chlorine
Chlorine plays a vital role in daily life, finding use in various fields, including:
Domestic Applications
In everyday life, chlorine is frequently used as a disinfectant to sanitize water sources and swimming pools. A 1% chlorine solution is also used as a cleaner for disinfection in bathrooms, kitchens, and restrooms. Chlorine, either in powder or tablet form, is a reliable alternative to chloramine B for sterilization purposes. It is important to wear protective gear when handling chlorine to ensure safe use.
Additionally, a diluted chlorine solution can be used to disinfect fresh fruits and vegetables, helping to remove toxins such as pesticides and bacteria.
Water Treatment
-
Swimming Pool Disinfection: Chlorine eliminates harmful bacteria and improves water clarity and odor.
-
Potable Water Disinfection: For drinking water, chlorine is used at a concentration of 1%. It is continuously added to water storage tanks to maintain a residual chlorine level of 0.1–0.2 ppm, ensuring constant microbial control.
Industrial Applications
-
Chlorine is used in the bleaching of textiles and paper and in the production of rubber, plastic, and bleach solutions (such as Sodium hypochlorite solution - Javel water).
-
A 0.5% chlorine solution is used for disinfecting dairy and food processing plants.
-
Chlorine is also applied in treating industrial wastewater from plants producing packaging, food, and beverages.
-
In general, chlorine is used for microbial control and water disinfection across numerous industries.
Aquaculture
In the aquaculture sector, chlorine is used for disinfecting tools, equipment, and machines. It is also employed to sanitize ponds, lakes, and aquaculture tanks, effectively controlling bacteria and algae.
The usage method involves dissolving chlorine in water at a ratio of 5–6 grams per liter. Specific application rates include:
-
Disinfection of tanks and equipment: 100–200 ppm for 30 minutes.
-
Treatment of parasitic diseases: 0.1–0.2 ppm.
-
Bacterial infections: 1–3 ppm for 10–15 minutes.
-
Pond floor disinfection: Maintain a chlorine residual concentration of 50–100 ppm.
-
Aquaculture water disinfection: 20–30 ppm.
Instructions for proper use and storage of Chlorine
Chlorine should be stored in sealed containers in cool, ventilated areas away from other chemicals. It must not be exposed to direct sunlight, open flames, or high temperatures.
Chlorine can react violently, causing fire or explosions when it comes into contact with substances like glycerin, acetic acid, Fe₂CO₃, phenol, alcohol, alkali metals, amines, metal oxides, organic compounds, ammonium compounds, reducing agents, and sulfur. Therefore, it must be stored away from such substances. In case of fire, do not use water, foam, or CO₂. Instead, use dry sand or soil to extinguish the fire.
Do not dispose of chlorine in ponds, lakes, streams, or public water systems. If contaminated or decomposed, do not reseal the container; instead, store it in a separate, well-ventilated area.
When diluting chlorine, always add the chemical slowly into the water and stir with a plastic rod until fully dissolved. Never reverse the procedure.
During handling, workers must wear protective gear, including masks, gloves, goggles, and appropriate protective clothing.
Emergency procedures for Chlorine exposure
If an accident involving chlorine occurs, take the following first aid measures:
-
Skin contact: Immediately remove contaminated clothing and wash the affected area thoroughly with soap or clean water.
-
Eye contact: Flush the eyes with clean water for 15 minutes, then seek medical attention.
-
Inhalation: Move the victim to an area with fresh air. If they are not breathing, perform artificial respiration and seek medical help immediately.
-
Ingestion: Drink plenty of warm water to induce vomiting and promptly seek medical attention.
