WebConversely, ORP could be low despite high free chlorine if combined chlorine is high, cyanurate is present, pH is elevated, and contamination is high, meaning that the water has non-satisfactory disinfection power. As background, consider that much of the historical study of ORP has focused on swimming and spa environments. WebHOCl, and ORP increases (larger mV readings) to reflect this shift in oxidative potential. Recent research in commercial and model postharvest water systems has shown that, if necessary, ORP criteria can be relied on to determine microbial kill potential across a broad range of water quality. In other words, an ORP of 700 mV at pH 6.5 has the same
