Sodium dichloroisocyanurate (NaDCC) tablets as an alternative tosodium hypochlorit

I just came across a post about this on another forum. It's the first I'm reading anything about it. They offered a link from UNICEF that I'm sharing. What does anyone else know about this?  (Original post is over on This Blue Marble: https://thisbluemarble.com/showthread.php?t=77254 )

Sodium dichloroisocyanurate (NaDCC), which is widely used in emergencies, is analternative source of chlorine that may present certain advantages over NaOCl for household-based interventions indevelopment settings. We summarize the basic chemistry and possible benefits of NaDCC, and review the availableliterature concerning its safety and regulatory treatment and microbiological effectiveness. We review the evidenceconcerning NaDCC in field studies, including microbiological performance and health outcomes. Finally, we examinestudies and data to compare NaDCC with NaOCl in terms of compliance, acceptability, affordability andsustainability, and suggest areas for further research. ---CONTINUED---

Here's another from World Heath Organization:

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, for the disinfection of water. It is widely used as a stable source of chlorine for the disinfection of swimming pools and in the food industry. It is also used as a means of disinfecting drinking-water, primarily in emergencies,  when  it  provides  an  easy-to-use  source  of  free  chlorine,  and,  more  recently,  as  the form of chlorine for household point-of-use water treatment.   ---CONTINUED----
