Eliminates bacteria and algae in industrial water cycles
Sodium dichloroisocyanurate is widely used in industrial circulating water systems to kill bacteria and algae to ensure clean water quality and safe and stable system operation. This article will introduce the application of sodium dichloroisocyanurate in industrial circulating water systems, including its bactericidal and algae killing mechanism, precautions for use and future development directions.
First of all, sodium dichloroisocyanurate is a highly efficient oxidant with strong bactericidal and algicidal effects. When sodium dichloroisocyanurate is added into the circulating water system, it will quickly react with organic substances and proteins in the water, releasing high concentration of active chlorine, destroying the cell wall and cell membrane of microorganisms, and then achieving the purpose of sterilization and algae removal . In addition, sodium dichloroisocyanurate also has high stability and heat resistance, and can exert stable bactericidal and algicidal effects under different water quality conditions.
Secondly, the following points need to be paid attention to when using sodium dichloroisocyanurate for sterilizing algae. First of all, it is necessary to determine the dosage concentration and usage method of sodium dichloroisocyanurate according to the specific water quality conditions and microbial species. Secondly, the appropriate dosing method and dosing time should be selected to ensure that sodium dichloroisocyanurate can fully exert its bactericidal and algae killing effect. In addition, attention should be paid to the storage and use environment of sodium dichloroisocyanurate, avoid contact with other chemical substances, and prevent unnecessary dangers.
Finally, the future development direction is to develop more environmentally friendly, low-toxicity, low-dose bactericide algicides to adapt to the trend of environmental protection and health. For example, some new organic acids and microbial bactericides are receiving extensive attention and research. In addition, by adopting advanced water treatment technology and equipment, the use of bactericide and algaecide and the impact on the environment can be effectively reduced, and the sustainable development of the industrial circulating water system can be realized.
How to use and dosage
Sodium dichloroisocyanurate is a bactericide and algicide widely used in the field of water treatment, and is often used in the treatment of industrial circulating water, cooling water, swimming pool water and other water bodies. Its usage and dosage are as follows:
Sodium dichloroisocyanurate is usually used in the form of granules or powder, which can be directly added to water, or dissolved and added to water. During use, it needs to be dispersed evenly in water so that it can exert its best effect. For industrial circulating water systems, it is generally necessary to inject it into the water tank or water pipe in the system to make it evenly distributed throughout the system.
The amount of sodium dichloroisocyanurate depends on factors such as water quality, water quantity, and ambient temperature. It is generally recommended to determine the dosage according to the water quality and the desired bactericidal and algae killing effect. It needs to be adjusted according to the actual situation during use and added regularly according to the cycle. The recommended dosage is usually 10-20 grams of sodium dichloroisocyanurate per cubic meter of water.
To sum up, the application of sodium dichloroisocyanurate in industrial circulating water system is very important and extensive. In the process of use, it is necessary to pay attention to reasonable use methods and precautions. At the same time, the future development direction is to develop more environmentally friendly, low-toxicity, and low-dose bactericides and algicides, and to adopt more intelligent and automated technologies to realize industrial circulating water systems. of sustainable development.
It should be noted that in the process of using sodium dichloroisocyanurate, it should be operated strictly in accordance with the product manual or the guidance of professionals to avoid accidents caused by improper use. At the same time, you should also pay attention to safety protection during use to avoid contact with the skin or inhalation of its gas. After ingestion, it has obvious gastrointestinal corrosion and may have abnormal liver function. If inhaled, move to fresh air and give oxygen if breathing is difficult. In case of eye contact, immediately rinse with water for 15 minutes, if the symptoms persist, go to the hospital for treatment. In case of skin contact, rinse immediately with plenty of water. If skin irritation is not relieved or aggravated, go to the hospital for treatment. Contaminated clothes should be washed before wearing. If swallowed by mistake, gastric lavage, vomiting, catharsis and acid-base neutralizer are not recommended, and 100-200 ml of milk, egg white or aluminum hydroxide gel can be taken orally immediately.
