CRYPTOSPORIDIUM RISK MANAGEMENT USING UV

摘要

This paper reviews the emergence of ultraviolet radiation (UV) as a cost-effective method for reduction of the risk of Cryptosporidium (crypto) infection. UV fills technology gaps for crypto inactivation/removal, particularly for the following situations: 1. Municipal filtration plants using chlorine especially those whose filters cannot reliably provide low turbidity ( < 0.3 NTU) filtered water. 2. Filters operating with high-risk agricultural catchment sources needing enhanced crypto inactivation/removal. 3. Municipal water supplies with low turbidity, low colour water which is not filtered. 4. It is also being applied for disinfection of tertiary treated wastewater prior to re-use The paper cites three case studies.
