Appropriate technology for iron filtration from ground water

Abstract

The Northeastern region of Thailand does not only face the problem of lack of surface water for consumption, but many provinces in the region also face the problem of poor quality underground water due to certain dissolved substances such as iron, manganese, hardness and salts. This project deals with the application village-level technology to eliminate the dissolved substances from the water, especially the iron and the manganese. The method depends on the principle of rapid filtration using sand as the filter, but it is an up-flow filtration. Such filtration is regarded as the best filtration method because the sand filters out the larger particles first.
