没问题,这个问题在设计工艺时候已经考虑,也就是有足够的NH3Cl加入抑制那些已经deactivated病菌再生。放心吧。

原来看过一篇报道,说edmonton这里的水偏硬,用过滤器过滤后更好。还有一次有人打电话到家里做调查,听到我说对edmonton的水质很满意后非常吃惊,估计那个人也觉得这里的水不是很好。2 D" H! O' ^& {. N0 p

EPCOR的水网上可以查到报告,这个你都不信,是不是以为他们也会造假?心理作用不要过于严重了。

建议你去大学听听课程。里面有很多EPCOR公司的水质研究与报告,包括工艺(几道工序)。我已经听过了,所以我知道。如果你承认出厂水质不错,那么剩下的问题就是供水系统(网络)问题,这个问题在工艺中已经考虑。(欧洲用臭氧杀菌+chorine,所以含量比这里只用chorine residue控制供水系统要低,他们好像7ppm,我们这里好像用10多ppm含量,保证供水系统水的质量到你家里水龙头)

Yes, you can drink from the tap directly. But we do NOT have the best quality of water in Edmonton considering where the water intake is placed.
