    Report: Development of Slow Sand Filter Prototype - Philippines (1991)
    ABSTRACT: Water supplies on the island of Mindanao in the Philippines are frequently contaminated. Because of sparse population and low disposable income, sophisticated treatment facilities are quite often not feasible. Slow sand filtration is an inexpensive means of obtaining potable water without altering the aesthetic quality or addition of chemicals, both of which are important to locals.
