Description
本发明涉及一种陶瓷过滤器。尤其涉及一种用于过滤液体、尤其是自来水(tap water)以便从中除去病原体或污染物(或致污物)的陶瓷过滤器。
由于很多被认为是饮用水源(例如公用设施或集团供水方案、井水)的变化的质量,一般而言,这样的水是不适于饮用的,并且在某些极端情况下,很多还可能含有病原体或污染物,其可以引起严重疾病。例如,一些饮用水源可能含有有害的原生动物或细菌,如隐孢子虫属(Cryptosporidium)、贾第虫属(Giardia)和埃希氏大肠杆菌,由于使用它们能引起疾病。因此,对于购买瓶或其他合适容器中的用于饮用目的的水有增加的趋势,而且购买这样的水也可能是相当昂贵的。例如,对于运动员而言,当练习时,运动员需要有规律地摄入大量的水,因此对于瓶装水的支出可能尤其高。
陶瓷在过滤器中作为介质的使用是已知的,包括用于净化液体如自来水的过滤器。然而,这样的陶瓷过滤器在质量方面有变化,通常体积庞大且是非便携的,并且不能完全依靠于此而从水中除去病原体如原生动物。因此,需要一种能克服这些问题的过滤器。
本发明目的在于提供一种陶瓷过滤器,该过滤器能够从液体如自来水中除去污染物(或致污物),包括但不限于有害的原生动物如隐孢子虫属和贾第虫属、以及细菌和病毒。本发明的陶瓷过滤器具有很多种潜在的应用。例如,它能用于当被从容器中汲取出来时净化盛装在容器如瓶中的干线自来水(mains tap water)。
