COMPARISON OF THE DISINFECTING POWER OF C HLORAMINE-T AND SODIUM DICHLOROISOCYANURATE ON RIVER WATER

Troops in operation have chloramine T tablets (12.2 mg chloramine per tablet) in ready-to-eat-meals, developed by Land Forces Commissarial. One or two tablets dissolved in a flask cannot ensure satisfactory dis infection of river water 30 min, after treatment, because of several i nhibiting factors (dissolving speed, water pH, chloramine activity). O ne 8.5 or 17 mg sodium dichloroisocyanurate (Na DCC) tablet per litre or flask makes river water safe for drinking after 30 min., with good remanence after 24 hours. The main inhibiting factor is high level of organic matter. As no acute or chronic toxicity has been reported in m an and usage is on short term periods, replacement of chIoramine T by 8.5 mg Na DCC tablets in ready-to-eat-meal is suggested.
