Since unsafe water elicits a broad spectrum of bacteriological, parasitological and virological diseases, purification of polluted drinking water has to be developed in tropical rural regions. Around 70% of rural wells and 7% of bore-holes contain water unsafe for human consumption. Water is also contaminated during transport and storage. Several techniques of purification have been recommended to protect drinking water. Recently, sterilisation in the U. V. or simply in the sun rays has been systematically tested. In tropical rural areas, solar disinfection has given questionable results. It affords no guarantee for the health of the consumer in contrast with other techniques as chlorination.
由于不安全的水会引发广泛的细菌学、寄生虫学和病毒学疾病，因此必须在热带农村地区开发受污染饮用水的净化方法。大约70%的农村水井和7%的钻孔所含的水对人类消费不安全。水在运输和储存过程中也会受到污染。已经推荐了几种净化技术来保护饮用水。最近，紫外线或仅仅在阳光下进行消毒已得到系统测试。在热带农村地区，太阳能消毒的效果令人质疑。与氯化等其他技术相比，它不能保证消费者的健康。
