MIOX – Mixed Oxidants 1 OBSERVATIONS ON THE USE OF MIXED OXIDANTS IN SWIMMING POOLS Mechanisms for Lack of Swimmer’s Complaints in the Presence of a Persistent Combined Chlorine Measurement

Evidence from reports in the technical literature, laboratory research, and operational experience with the MIOX mixed-oxidant solution (MOS) in swimming pool water strongly indicates that MOS causes steady oxidation of organic nitrogen compounds and organic chloramines, and rapid completion of the breakpoint reaction on inorganic –N– fragments from that oxidation rather than allowing accumulation of them (including volatile NHCl2 and NCl3) in the pool water, as is likely the case using chlorine (to wit, the common swimmer's complaints of "chlorinous" odors and burning eyes when bleach/hypochlorite is used for disinfection). This steady removal of organic nitrogen and rapid completion of the breakpoint reaction would be expected to cause the following beneficial effects, as have been noted by swimmers in and operators of virtually all pools using MOS as a replacement for chlorine for disinfection 1 :
