A new water disinfectant; a comparative study

Halamine water disinfectants

“…Disinfection of Staphylococcus aureus by DCDMH was found to be more rapid than by free chlorine according to Johns 75 and was considered to be equivalent from experiments conducted by one of these authors. 76 In a field test of DCDMH as a sanitizer for food service material (beer glasses washed, rinsed, and sanitized in a tavern under the supervision of a health department employee, in this case), the compound was evaluated at an input halogen level of 100 mg/€ of chlorine over a period of 5 hr during which approximately 500 glasses were washed, rinsed, and sanitized. 77 After 3 hr of use, the DCDMH began to fail as an adequate bactéricide, and concurrent chlorine determinations indicated a drop of total chlorine to approximately 50 mg/€ at that point.…”

“…Table 8 summarizes the minimum bactericidal concentrations for compound I, l,3-dichloro-5,5-dimethylhydantoin, NCS, and calcium hypochlorite to affect an 8-log kill of 11 species of bacteria. 76 The results in Table 8 show that compound I was competitive in disinfection efficacy with the commercial disinfectants for most of the bacterial species. Clearly 5. aureus was the most resistant organism to all of the disinfectants.…”

Retrometabolism‐Based Drug Design and Targeting

“…Structure 174 proved to be a particularly effective bactericide in a laboratory water treatment plant [389]. It is exceptionally stable in water and in dry storage [390,391]; it is nontoxic in chicken's drinking water at 200 mg/L, and it detoxifies aflatoxin [392]. The mechanism of action of these compounds involves inhibition of bacterial growth by inhibiting DNA, RNA, and protein synthesis [393].…”

Novel enhancement of thin-form-factor galvanic cells: Probing halogenated organic oxidizers and metal anodes

“…Solid chlorinated oxidizers have been utilized for organic synthesis and disinfection purposes for almost 40 years [40][41][42]. One of the most widely accepted mechanisms of disinfection is the formation of oxidizing hypohalogenous acids upon water contact.…”
