Abstract
In the present study, sterilizing and antibacterial performance tests of Polybutylene pipe with nano-silver were carried out in the testing bench of water supply facilities. Experimental results show that the average sterilizing and antibacterial rate of two micro-biological samples such as E. coli and S. aureus is about 90% in case of stillness experimental condition and 99% in case of flowing experimental condition, when elapsed time is 120 hours and 3 hours, respectively. Experimental results also show that the supply water velocity in nano-silver Polybutylene pipe varies from 1 m/s to 1.5 m/s, the elapsed time needed sterilizing rate reach to 100% decreases.
