Water Disinfection Applications
Drinking Water Disinfection remains one of the world’s challenges in the 21st Century. Delivery of clean, potable water becomes more difficult with the steadily growing world population. Despite the many ways to disinfect potable water, only two of them provide a measurable residual – chlorine and chlorine dioxide. Chlorine dioxide provides many advantages over the chlorination process.
Hospital Water Disinfection Hospitals must pay particular attention to disinfecting their water. There are two types of disinfection processes to consider: shock disinfection of all water distribution systems (cold, hot and toilet flush water) and continual water disinfection during hospital operation. In both cases, appropriate disinfection is a critical issue because hospitals are designed for sick people with compromised immune systems. The best disinfectant for treating hospital water is chlorine dioxide, because this process provides a measurable residual, and is very efficient against bacteria, protozoa, viruses, and super bugs.
Wastewater Disinfection Wastewater treatment is important as a first line of defence against waterborne infections. Wastewater disinfection together with proper wastewater treatment must be considered one of the barriers in multibarrier approaches for delivery of hygienically clean potable water.
Swimming Pool Disinfection is critical for public swimming pools, and highly recommended for private swimming pools. Without proper disinfection, swimming pools can become carriers of bacterial infections, and spread diseases caused by protozoa (single cell organisms) and fungi. Chlorination – a commonly used pool disinfection process is not efficient against protozoa and fungus; while chlorine dioxide offers broader protection against bacteria, protozoa and fungi. Both disinfectants have to be applied with care because each of them has pros and cons.
Lagoon Disinfection becomes critical when coliform counts exceed regulatory values prior to lagoon discharge. With growing requirements regarding wastwater treatment processes, disinfection of lagoon effluent may become a mandatory step.
