Is it necessary to add liquid chlorine in circulating water treatment?
Thread Content
As the title says. If liquid chlorine is added to treat the circulating water. Since liquid chlorine is a highly toxic chemical, its use requires approval, registration, and other procedures, making it very complicated. So, when treating circulating water, is it necessary to add liquid chlorine, or can other less toxic chemicals be used as alternatives? What do advanced circulating water treatment processes look like these days?
Chlorine is used for sterilization and algae control, right? Of course it can be replaced; there are many agents available for use as sterilizers in circulating water systems. They can’t be considered non-toxic, but they all belong to the low-toxicity category, and they all have some degree of corrosiveness
Chlorine is mainly used for sterilization and algae control, and there are many types of it. See which one is suitable for you, and choose the cheapest one based on a comprehensive evaluation; there are also corrosion inhibitors.
There are many disinfectants that can replace chlorine, such as chlorine dioxide, sodium hypochlorite, hypobromous acid, and so on. Chlorine is a highly toxic and dangerous substance, and its transportation and storage are subject to strict regulations. Due to the complexities associated with its management, many organizations now use other disinfectants as alternatives; these alternatives achieve similar results.
Not necessarily; you can choose other medications. . Because chlorine is quite dangerous, and an increased concentration of chloride ions in water also causes severe corrosion of pipes……
Alternative products that can be used to add chlorine, such as solid chlorine, have the same disinfection effect as liquid chlorine.
The purpose of adding liquid chlorine to circulating water is to sterilize and eliminate algae. Adding liquid chlorine is cost-effective and yields good results; however, there are safety issues associated with its storage and transportation. As a result, various alternatives are now available. Liquid chlorine is an oxidizing algicide; therefore, chlorinated or brominated substances can be used as substitutes. Options such as chlorine dioxide, sodium hypochlorite, trichloroisocyanuric acid, or various bromine-based compounds can serve as replacements, with basically no of the risks associated with liquid chlorine. There are also some peroxides or persulfides used in circulating water, such as potassium persulfate, although their application scope is not very wide.
For safety reasons, liquid chlorine is largely being phased out; there are now many types of disinfectants available as alternatives, such as sodium hypochlorite, as well as non-oxidizing disinfectants···
Liquid chlorine poses safety issues not only during storage and transportation, but also many dangers during actual handling and loading/unloading processes. At the same time, most chlorination equipment is from foreign brands and is expensive. But for some reason, many design institutes still prefer to use it. Using sodium hypochlorite is simple and safe.
Whether to use liquid chlorine depends on the size of your circulating water system; if the system is large, liquid chlorine is a better choice as it is cost-effective, and the associated risks are not insurmountable. If the system is small, it’s best not to use liquid chlorine; as the others have said, it poses certain risks and the approval procedures are complicated.
