Applications And Effects of Sodium Dichloroisocyanurate Dihydrate

Sodium dichloroisocyanurate dihydrate is a solid chlorine bleaching agent generally used as an alternative to sodium hypochlorite for water treatment. Calibration substance for the photometric determination of active chlorine. Guidelines for the analysis of waste water and surface water. Fengbai Sodium dichloroisocyanurate dihydrate can be used as a chlorine source to convert alkoxyl-s-triazines into N-chlorinated alkoxy-s-triazines.



Sodium dichloroisocyanurate for Household Water Treatment

Household water treatment using sodium hypochlorite (NaOCl) has been recognized as a cost-effective means of reducing the heavy burden of diarrhea and other waterborne diseases, especially among populations without access to improved water supplies. Sodium dichloroisocyanurate (NaDCC), which is widely used in emergencies, is an alternative source of chlorine that may present certain advantages over NaOCl for household-based interventions in development settings. We summarize the basic chemistry and possible benefits of NaDCC, and review the available literature concerning its safety and regulatory treatment and microbiological effectiveness. We review the evidence concerning NaDCC in field studies, including microbiological performance and health outcomes. Finally, we examine studies and data to compare NaDCC with NaOCl in terms of compliance, acceptability, affordability and sustainability.

Used for Swimming Pools and Industrial Water Systems

Used mainly as a disinfectant and algaecide for swimming pools and industrial water systems. Also used for sanitizing and disinfecting food and non-food contact surfaces and sanitizing laundry. Used as an antimicrobial for drinking water systems.

When dissolved in water, all chlorinated isocyanurates form hypochlorous acid, a weak acid and oxidizing agent; A severe eye and mild skin irritant. An oxidizer that may intensify fire; A strong eye irritant. Harmful by ingestion.

Disinfectants used to treat sewage and wastewater include chlorine, chlorine dioxide, ozone, sulfur dioxide, hydrogen peroxide, and 1,3-dichloro-5,5-dimethylhydantoin. Products of decay include hydrogen sulfide, methane, nitrogen, carbon dioxide, and ammonia. Faulty equipment can generate dangerous levels of carbon monoxide. 

Disinfectants are chemicals used to inhibit or kill microorganisms. Disinfectants are also called antiseptics or biocides. Disinfectants are generally used in physical media (solutions or on surfaces) while antiseptics are applied to skin or other living tissue. Some of these agents are also used as preservatives for food, drugs, and other domestic and industrial products.


The Effects on The Human Body

Many of these chemicals are skin and respiratory sensitizers. The following can cause occupational asthma: glutaraldehyde, formaldehyde, sodium bisulfite, chloramine T, hexachlorophene, chlorohexidine, benzalkonium chloride, isononanoyl oxybenzene sulfonate, lauryl dimethyl benzyl ammonium chloride, and isothiazolinones. A study of 175 workers exposed to chloramines, aldehydes, and quaternary ammonium disinfectants in the food industry showed increased acute irritation symptoms but not chronic respiratory symptoms. 

Sodium dichloroisocyanurate is the sodium salt of a chlorinated hydroxytriazine and is used as a source of free available chlorine (in the form of hypochlorous acid, HOCl) for the disinfection of drinking-water. Sodium dichloroisocyanurate can be manufactured either as the anhydrous salt or as the dihydrate. It has not been evaluated previously by the Committee. At its present meeting, the Committee considered the safety of sodium dichloroisocyanurate in relation to its possible use as a disinfectant for drinking-water in emergency situations, and for routine use in some water supplies.

Mastering Sanitization with Sodium Dichloroisocyanurate

Image
  In the world of sanitization and water treatment, one compound has earned a reputation as a master in the art of disinfection: sodium dichloroisocyanurate. Often known as SDIC, this unassuming chemical is the key to maintaining clean and safe environments, ensuring water is pure, surfaces are sterile, and health is protected. In this blog post, we'll delve into how sodium dichloroisocyanurate is the master of sanitization and explore the science and applications that make it an indispensable tool in this field. The Chemistry of Cleanliness Sodium dichloroisocyanurate is a white, crystalline powder or granular solid with a molecular formula of C3Cl2N3NaO3. This formula hints at the secret to its powerful disinfection abilities. SDIC contains chlorine, a well-known disinfectant. When this compound is introduced to water, it undergoes a transformation, releasing chlorine ions.            The Power of Chlorine Chlorine ions are the unsung heroes in the b...

What Is Calcium Hypochlorite (CHC)

Image
 Calcium hypochlorite is a white solid that you can purchase in granular or tablet form. It is used to disinfect water and kill off bacteria that could make you sick. Its uses extend to swimming pools, drinking water for small communities and industrial food processing. Calcium Hypochlorite CHC 70% ( also called bleaching powder) is a white crystalline solid, decomposes at 170 C, decomposes  in water and alcohol, not hygroscopic, practically clear in water solution. It is produced by passing chlorine gas over slaked lime. Chlorine is a general biocide substance killing germs, micro-organisms, algae, etc. The most widely used chloride chemical disinfectants are chlorine, ozone, chlorine dioxide and chloramine. Hypochlorite is an alternative choline source when chlorine gas is impractical. The commercially available liquid form is sodium hypochlorite (NaOCl). Hypochlorite is the common name for chlorate(I) salt.  Calcium Hypochlorite quickly forms hypochlorous acid (the kil...
