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。

不建议喝。因为锅炉里面可能有防止水垢的化学品。即使没有添加,那么由于热水温度较高,细菌滋生速度较快,而且冷水供水系统中添加的抑制病菌的NH3cl已经不复存在,这都是危险,对身体不利。

No, not that chemical directly added in water, but chlorine instead, that results from chlorine additoin.

不过如果是怕化学物的话,我可以帮你们装上活性炭,很平宜的。Sears has it on sale for less than $50.00.,cartridge good for three years.不过人工方面。。。呵呵。

我没有怀疑EDMONTON水质不达标,从水厂出来的水水质肯定是达标的。我原来在一个污水处理厂干过几年,即便是污水如果达不到水质标准,我们也不敢注入到地下(增压,驱油),何况是饮用水,水质是不用怀疑的。 ...

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.
