| 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 microbiological 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 1m/s to 1.5m/s, the elapsed time needed sterilizing rate reach to 100% decreases. |
