Microscope Observation of the Microbial Distribution on the Wall of Different Pipe Material in Water Supply System
供水管网不同管材内壁微生物分布的显微观察

Scanning electron microscope,atomic force microscope and confocal laser scanning microscope were used to observe the microbial distribution and biofilm structure on the surface of stainless steel plugs and the wall of PPR pipe in the water distribution system.The results show that,it is not easy for microbial to attach on the surface of stainless steel plugs.Little bacteria was observed in a short period of time(less than 3 months).Bacteria can be easily observed in the sediment of the PPR pipe wall at the ...
