A water purification process eliminates or neutralizes chemicals, biological agents, and suspended solids. Some methods include boiling, filtration, membrane purification, activated carbon adsorption, distillation, chlorination, and ozone treatment. Bleach is one of the most popular water purifiers used nowadays.

Bleach is an oxidizing agent that breaks down impurities in water into harmless by-products. Water purification has been around for over 100 years, and it's relatively easy to use and affordable.

By releasing free chlorine into the water, bleach kills bacteria and other pathogens. By reacting with organic matter in the water, chlorinated compounds create new compounds that are less harmful.

What is bleach?

Bleach is the title given to a set of compounds, which can be used industrially and domestically to whiten clothes, lighten hair color and eliminate stains.

Many bleaches have broad-spectrum bactericidal properties, which makes them suitable for disinfecting and sterilizing and therefore are used in swimming pool sanitation to control bacteria, viruses, and algae and in several areas where climatic states are needed.

They’re also utilized in several industrial processes, especially from the bleaching of wood pulp. Bleach can also be used for removing mold, killing insecticides, and increasing the longevity of cut flowers.

The whitening procedure has been understood for millennia, but the compounds used for whitening caused by the work of numerous 18th-century scientists.

Chlorine is the foundation for chlorine bleach: for instance, the solution of sodium hypochlorite, which will be so omnipresent that many calls it “bleach,” and calcium hypochlorite, the active chemical in “bleaching powder.”

Oxidizing bleaching agents who don’t contain chlorine are often based on peroxides like hydrogen peroxide, sodium percarbonate, and sodium perborate.

  2. Stir the mixture until it's completely dissolved.
  3. Cover the bowl with a plastic bag and let it sit for 1 hour or more, depending on how dirty your water is, to begin with. After this time has passed, pour the solution into another container (preferably one that can be used again). If you do not have enough chlorine bleach in step 1 to cover all your water, add more to the water as needed.

Chlorine in the bleach will play the role of disinfectant in water purification. It kills pathogenic bacteria. The concentration of chlorine bleach ranges from 5 to 10%. It has been recommended to use a concentration of 8 to 10%.

If a lower concentration is used, the disinfection will be weaker. If you use a higher concentration, there may be side effects such as skin irritation. In addition, the residual effect of chlorine bleach cannot be ignored. As a result, it is vital to take precautions to ensure safety when using the product.

What are Disadvantages of Using Bleach for Water Purification?

Bleach is a method of water purification that adds chlorine to the water, making it non-potable. That means chlorine is deadly and causes many toxic substances in the body. People with bladder and kidney problems are more prone to urinary tract infections.

Moreover, bleaching can also cause harm to people who try to store the bleach in the container for a long time. It increases the toxic contents of the bleach. On the other hand, water purification with the help of iodine is safe and less harmful.

Tips on different terminology related to purifying water with bleach.

Regular household bleach

Bleach is a chemical compound that reacts with organic molecules present in water, causing them to break down and bleach out of the water. It effectively kills any pathogen or other contaminants in the contaminated drinking water. Bleach does not destroy all bacteria or viruses. If chlorination and boiling have failed, household bleach can serve as an additional measure.

Household chlorine bleach

Bleach, also known as chlorine bleach and household chlorine bleach, is a common household product. It's used to disinfect many objects such as pools and household fixtures. Bleach is fatal if it comes in contact with the eyes or mouth of an infant or young child. Corneal injuries can cause blindness or even death. The Centers for Disease Control has shown that mixing bleach with water results in an explosion and fire. So, it is important to use only bleach and not water.

Using bleach for water purification can be dangerous if not done properly. The product should be used in a safe manner and never mixed with other chemicals such as ammonia or chlorine (a chlorinated pool). Also, before using any household cleaning product, make sure you read the label on the bottle to ensure it's safe for your specific needs. If you have questions or concerns, contact your local water utility.

Chlorine level

The chlorine level in your well water is the concentration of chlorine in the water. Chlorine levels increase when there is pollution. The rate at which chlorine levels increase depends on how much bacteria and algae are present in the well system. Living organisms need chlorine to survive. These substances remove it from circulation to use themselves for growth or respiration. Excess chlorine can damage health. It causes eye irritation from its effects on mucous membranes. e.g., conjunctivitis.

Chlorine odor

This is a chemical reaction of chlorine and oxygen. The chlorine odor comes from the oxidation of chlorine to chloride ions (Cl–) + hypochlorous acid (HOOC–) + ozone (O3). Organic chemicals, including old sewage and industrial wastewater, can form chloramines and trihalomethanes from chlorine disinfection. They react with other impurities in the water to form chlorocarbons, which are used as disinfectants in public water systems.

Drops of bleach

The bleach drops are used to purify the water. Mix 16 bleach drops with six drops per liter of water, add it to a cup, heat it until it boils, and pour it into a bowl. It will take about two minutes.

  • CDC guidelines indicate, one way to prevent the spread of COVID-19 is to disinfect surfaces using bleach and other disinfecting products. 

  • EPA guidelines limit the amount of chlorine in a system to four parts per million rather than eight parts per million since chlorine dioxide seems to affect the taste of water negatively.
