2022-3-23 · Chlorine is commonly used as a disinfectant during drinking water treatment because it is a strong oxidant that inactivates pathogens (e.g., bacteria and viruses). When chlorine is used to disinfect water, it is added to the water as sodium hypochlorite (NaOCl). The molecular weight of NaOCl is 74.44 g/mol.
2009-1-26 · Disinfectant Chlorine (CL) gas is a greenish yellow in colour and about 2.5 times heavier than air. Liquid chlorine is amber coloured and about 1.44 times heavier than water. CL gas is moderately soluble in water with a maximum solubility of about 1 % at 10°c. When chlorine is added to water, it first reacts

2021-11-10 · Unlike chlorine, ozone leaves no harmful by-products in the water or the environment. Ozone quickly reverts back to pure oxygen if unused. Ozone is one of the strongest and fastest commercially available disinfectant and oxidant for water treatment, purifying water 3000 time faster than chlorine.
Household bleach (5.25% sodium hypochlorite) mixed with water, is an inexpensive and effective disinfectant. By mixing different amounts of bleach with water, you can make a high, intermediate, or low-level disinfectant. High-level Disinfection: (1:10 dilution of bleach | 5000 ppm) When to be used: Cleaning up a large blood or body fluid spill.
2021-1-22 · 4 1 water treatment conditions [2, 6, 15]. Thus, the disinfection efficiency of chlorine depends on pH 2 and can be more effective at lower pH [2, 6]. 3 Therefore, the results of previous studies with commercial sodium hypochlorite solution 4 are hardly appropriate for evaluating the feasibility of OSG chlorine as an alternative disinfectant 5 to the chlorine gas used in the water …

2021-7-22 · Today, chlorine is still a disinfectant often used for water treatment, but some countries have turned to chloramine as an alternative. Chloramine is an ammonia-chlorine mixture. Similar to chlorine, chloramine has been used as a disinfectant since the early 1900s but is becoming more and more popular.
Conclusion: Chlorine measurement is a very important measurement and it rarely occurs alone Water is susceptible to impurities and contamination with pathogenic germs. Chlorine is still the most important disinfectant for basin water and drinking water in the areas of emergency or transport chlorination.
This paper presents results describing the effectiveness of chlorine dioxide penetration into a drinking-water distribution system biofilm/corrosion matrix and decontamination of adhered Bacillus globigii spores, a surrogate for Bacillus anthracis.Biofilm and corrosion products were developed using biofilm annular reactors containing oxidized scaled, iron coupons.

At 10 °C and atmospheric pressure, one liter of water dissolves 3.10 L of gaseous chlorine, and at 30 °C (86 °F), 1 L of water dissolves only 1.77 liters of chlorine. Chlorine is a member of the salt-forming halogen series and is extracted from chlorides through oxidation often by electrolysis.
Chlorine Dioxide (ClO 2) is often used as a disinfectant in water treatment plants, with the main advantage of not producing THM's, like other Chlorine (Cl 2) disinfectants do.
When chlorine is added to water for disinfection purposes, it usually starts reacting with dissolved organic and inorganic compounds in the water. Chlorine can no longer be used for disinfection after that, because is has formed other products. The amount of chlorine that is used during this process is referred to as the 'chlorine enquiry' of ...
