Main Break Assessment and Optimization

摘要

A microbial risk model was developed to evaluate customer’s infection risksrnafter a main break and depressurization eventrn1. Virus is the controlling risk (7-log reduction needed).rn2. Effective flushing would remove ~3-log particles and control the Crypto infection risk.rn3. Additional 4-log virus inactivation (disinfection) is needed to control the virus infectionrnrisk.
