Is Chloramine-T safe to use as a general purpose disinfectant?


  • Posted by Aj Edgar on Wednesday, 4 December 2013

    Yes, Chloramine-T is traditionally used as a general disinfectant across various sectors including aquaculture, cattle, pig and poultry farming, hospitals and many more. Chloramine-T produces lesser disinfectant by product and remains active for longer period than other disinfectants such as chlorine.

    As with any treatment care should be taken to follow the guidelines cautiously. For example: dilution rates vary for different surface, equipment, livestock treatment. Water pH levels also affect the required dilution for treatment. While using in ponds care should be taken to keep the waters well oxygenated through aeration pumps. In addition, it is advisable to by pass the filters for three to four hours after application of the product to protect the favourable bacteria colonizing the filter.
