Chlorine and Water Disinfection

Chlorine is one of the most commonly used water treatments worldwide. Although effective at reducing a number of waterborne pathogens, it has daily dosage requirements. Unlike chlorine, the MadiDrop® does not alter the taste or smell of water and does not require sustained behavioral change. Its simplicity reduces interaction with the end user and the possibility of implementation errors. MadiDrop® field deployments have shown the MadiDrop® is preferred to chlorine and is effective when used with other treatment approaches, such as biosand filters, to protect against residual contamination.
