美国田纳西州E. C. C. C. 公司最近上市一种手提式饮水处理器(portable WaterTreatment Vnit),将不能饮用的水从这种净水器的上端倒入,而底部流出的便是干净、可口的饮水。这种利用重力作用过滤的净水器,内含有以科学方法注入少量银及银化合物的活性碳基层,当含银层吸收了水中的污染质后,使炭质活性化,而银的渐进动态效应则能防止细菌在过滤筒中滋生。该滤水器售价从40美元到49美元,每天可过滤3.8公斤的饮用水,使用年限为一年。
E.C.C.C. of Tennessee, USA, recently launched a portable WaterTreatment Vnit, which drains potable water from the top of the water purifier, and at the bottom is clean, tasty water. This type of water purifier that uses gravity to filter contains an activated carbon substrate that is scientifically infused with a small amount of silver and silver compounds. When the silver-containing layer absorbs contaminants in the water, the carbonaceous material is activated, and silver gradually moves. The effect prevents bacteria from growing in the filter cartridge. The filter is priced from US$40 to US$49, and can filter 3.8 kilograms of drinking water per day for a period of one year.
