High levels of ammonia in drinking water sources present a significant challenge to point-of-use chlorination in developing regions. By reacting with free chlorine almost instantaneously to form combined chlorine, ammonia can drastically reduce the disinfection efficacy, particularly with regards to viruses. SoChlor is a new approach that relies on simultaneous chloramination and solar disinfection to improve the inactivation of viruses in ammoniacal waters. While neither chloramination nor solar disinfection is effective against viruses when applied alone, their simultaneous application yields high levels of virus inactivation under a variety of conditions.
