Sodium hypochlorite An inherent feature of chemicals in the global market, hypochlorite bleaches have gained considerable popularity. With the increasing incidence of infectious diseases on a global scale, the demand for disinfectants, bleaches and disinfectant products is likely to accelerate. Hypochlorite bleaches are disinfectant products with the ability to kill a wide range of bacteria, fungi, viruses and pathogenic fungi, provided they are used with sufficient caution and in accordance with specific instructions for use.
Types of hypochlorite bleach
Hypochlorite bleach is a sodium salt obtained by dissolving hypochlorous acid in water with molecular ions and oxygen. The use of these bleaches has been accepted in countless industries including water treatment, textiles, pulp and paper, laundry and health care in many other cases, resulting in numerous benefits including water disinfection, surface treatment and Reduce odor. Sodium hypochlorite is a major component of the product, also called Clorox bleach, and plays the role of an active ingredient in laundry bleach used in the home, accounting for approximately 5.25% to 6% of total chlorine. Makes up.
Calcium hypochlorite, a dry or powdered form of hypochlorite bleach, is used as a chlorine compound to kill harmful bacteria and viruses. Calcium hypochlorite acts as an effective disinfectant for purifying water in hot pools and tubs and counteracting the danger posed by various disease-causing microorganisms and other contaminants. In addition, this plant is also used for water treatment, including in ponds, lakes and wells, as well as the regulation and removal of algae from water treatment facilities such as filters, tanks, etc.
Calcium hypochlorite is used as a disinfectant for drinking water by many small water systems in developing countries and to meet the water needs of the communities in the region and has great potential.
A good example of this is the small community of about 2,500 people in the village of Yamaranguila (Yamaranguila), located in the hills of southwestern Honduras. For the water needs of the village, a water supply system is used that uses the natural resources of the spring water in the underground sources. The water is treated with calcium hypochlorite and stored in a large tank, which then delivers clean drinking water through pipelines.
Developing effective water treatment developments to increase sales of hypochlorite bleaching products According to credible studies, Americans use an average of 300 million similar pools and waters each year. When it comes to pools or water parks, there is a certain smell that immediately evokes the image of water and freshness. However, this odor is not caused by water per se, but is the result of a chlorine product that is commonly used to disinfect and protect water from contaminants, usually calcium, sodium, or potassium hypochlorite.
Pool water contaminants can enter the water in various forms through swimmers, including bacteria in the water and viruses in cosmetics, sweat, saliva, etc., and this requires an effective disinfectant to Protects and maintains a safe pool environment. .
Between 2000 and 2014, there were more than 500 outbreaks of diseases related to swimming pools, hot tubs and other water-based playgrounds, the most prominent of which was cryptosporidiosis caused by the parasite Cryptosporidium, as well as other diseases. These include shigellosis and giardiasis. This increase in water-borne diseases has necessitated numerous regulations on pool water quality and, consequently, the dynamics of the hypochlorite bleach market.
Chlorination has been and continues to be the most widely used method of water treatment, especially in the treatment of residential pool water. The chlorination process usually involves the combination of sodium or potassium hypochlorite in aqueous solution for the combined properties of free chlorine formation, which is then used for disinfection and water treatment.
According to the recommendations of pool experts, the ideal chlorine level for effective water treatment in swimming pools is 1.0 to 4.0 parts per million.
Hypochlorite bleaches are generally found as a white solid powder that contains compounds such as calcium and sodium hypochlorite. Hypochlorite bleach is used in the treatment of drinking water, its antiseptic role due to its antimicrobial properties, rapid antibacterial action and durability.
The disinfection process involves the use of a solution of calcium hypochlorite with a concentration of 30 to 70% chlorine in order to acidify the water. Sediments are also removed in this process before the hypochlorite solution enters the treated water tanks to prevent clogging. To reduce the degradation of hypochlorite bleach used in drinking water, the US EPA has proposed changes to the pesticide label, advising users to maintain a pH of 11 to 13 in solution, out of direct sunlight. Prevent and store the solution at low temperatures for shorter periods of time.
Similarly, a myriad of developments are underway by several key industry experts and regulators to address the growing need for clean, treated and safe water around the world.
The main purpose of hypochlorite bleach changes in water treatment
In the United States, for example, the Mid-Atlantic Area provides free EPA support for small wastewater and water treatment systems in Delaware, Pennsylvania, Virginia, West Virginia, and Maryland, as well as the District of Columbia to protect and improve water quality throughout the region. Offers. This support extends to critical technical assistance and comprehensive operator training for public and private health center staff to assist them in adhering to clean water law standards to maintain its quality.
Similarly, the wastewater treatment plant in Stockton, California, is designed to revolutionize compliance with strict federal and state policies, as well as to support future jobs and housing expansion. The Stockton Municipal Regional Wastewater Treatment Facility Rehabilitation Project began on October 8, 2019 and will work with the North Stockton Delta Water Treatment Plant to rehabilitate and modernize the Regional Water Treatment Plant to meet the city’s commitment to responsible and sustainable water use.
In Bangladesh, meanwhile, the World Bank has provided $ 100 million in loans to boost water supply in more than 30 selected municipal locations. The loan, supported by IDA (International Development Association), is expected to facilitate the municipal water supply and sewerage project with the aim of providing clean piped water to municipal residents. This project includes the construction of numerous infrastructures, including water treatment facilities, water storage facilities, pipeline networks, and so on.
The evolution of the paper and cardboard industry in China is expanding the hypochlorite bleach market. Paper products and pulp are some of the most widely used materials for many applications worldwide. In 2016, total paper and cardboard production was estimated at 410 million tonnes, Statista claims, with more than half devoted to packaging paper production, while nearly a third to paper production. Graphically attributed.
The article is considered a renewable resource, and makes recovery very important in the industry. In fact, paper has one of the highest recycling rates of any material. In 2017, a significant percentage of paper and cardboard recoveries were recorded in the United States, a significant increase from the 1990s.
More than half of the world’s total paper production is accounted for by three major countries: the United States, China and Japan. In China, the production of paper and cardboard depends on the paper goods used, including old newspapers and magazines, discarded cardboard containers, and mixed paper grades such as raw materials. Paper and cardboard are widely used in a wide range of industries, including stationary stations, newspapers, textiles and packaging.
The paper packaging market in China is experiencing tremendous growth as a result of the booming e-commerce package sector, lower pulp prices and increased public awareness of the importance of environmentally friendly packaging materials. Paper recycling involves the use of hypochlorite bleaches, especially calcium hypochlorite, because it helps to remove ink and achieve the desired degree of whiteness during the bleaching process.
Due to the continuous processing of organic matter, water and heat, microbial contamination is very common in the paper production process. In this case, the use of calcium hypochlorite helps to eliminate any contaminants or components of biological fuels.
The bleaching stage of hypochlorite takes place after chlorination and alkaline extraction processes. Bleaching of hypochlorite is done both in one step or several steps. The single-step process is one of the oldest forms of hypochlorite bleaching and is used to dissolve lignin, natural dyes, and other contaminants in fiber. Since hypochlorite bleaching agents are not selective, it is necessary to control the reaction of the process to prevent cellulose degradation in addition to lignin.
Prevalence of Health-Related Infections and Infections Enhances Global Behavioral Pattern of Hypochlorite Bleach According to reports, the Health Care Research and Quality Agency (HAI) claims that HAI-related infections are the most common complication among patients. Are hospitalized. In fact, the CDC estimates that at least one case of HAI occurs in every 31 patients a year. Also, approximately 30 to 40 percent of HAIs are the result of contamination by health care workers who have been in contact with infected or quarantined patients or contaminated environments.
This growing prevalence of contamination in hospitals and the subsequent increase in the need for disinfection are likely to motivate the global hypochlorite bleach market. Sodium hypochlorite-based disinfectants show strong application potential in counteracting the secretion of blood with HIV or hepatitis B virus, as well as hard surfaces, due to the important tendencies of its ability to correct and improve.
Regular use of hypochlorite bleach to disinfect various levels of the hospital against the risk of infection and contamination is hospitalized. In the United States, most sodium hypochlorite-containing bleach products include the Clorox antimicrobial wipe, the high-level disinfectant system, and the hospital cleaning disinfectant.
The popularity of these products for disinfecting hospitals has been largely attributed to their strong antimicrobial properties, non-toxic and non-toxic surface resistance, and hard water resistance. In addition, these products are cost-effective and help to remove biofilms of fixed or dried organisms from surfaces. As the expansion of water treatment and the pulp and paper sector is growing rapidly, the trend in the hypochlorite bleaching industry will undergo a major transformation in the coming years.
