Abstract

Cambodia is a typical country that a very famous tourist destination in South Asian regions, but water has some serious problems. As a public hygiene point of view, water problems in Cambodia can be roughly classified into two categories. A numbers of the report revealed that thermotolerant coliform(TTC) bacteria and arsenic(As) pollution representative species as a representative pollutant for surface water and ground water problems, respectively. In recent years, home water purifier systems for various filter systems including BSF(Bio-Sand Filter), MF and RO have been spread and adopted in rural areas. However, BSF and composite membrane processes are recognized as an undesirable and representative method due to unreliable efficiency, high cost and maintenance issues. In order to develop a small-scale ceramic filter as a home water purifier, the applicability of two types of gravity ceramic filter using clay and red soil in the part of the Northwest was made and compared in this research.

캄보디아는 동남아 지역에서 매우 유명한 관광국가임과 동시에 심각한 물 문제를 가지고 있는 대표적 국가로 인식되고 있다. 공공위생의 관점에서 캄보디아의 물 문제는 대략 두가지 카테고리로 구분된다. 상당히 많은 수의 보고서들이 지표수와 지하수 문제에 대해 분원성 미생물과 비소 오염이 각각 가장 대표적인 문제인 것으로 보고하고 있다. 최근에 가정용 정수기 시스템으로서 생물-모래여과기, MF, RO 등 다양한 소재를 이용한 시스템들이 농촌지역에 보급/채택되었다. 그러나 BSF와 조합형 막여과 공정들은 신뢰하기 어려운 효율, 높은 멤브레인 교체비용과 유지관리의 문제점들로 인해 당초 기대에 미치지 못하는 기술로 인식되기 시작하였다. 금번 연구는 가정용 정수기로서 활용이 가능한 소형 세라믹 필터를 개발하기 위해 캄보디아 북서부의 점토와 황토를 이용하여 두 종류의 중력식 세라믹 필터를 만들었고, 이들에 대한 현지 적용성 여부를 평가하였다.
