Abstract

Laboratory investigations were carried out on a simple iron removal plant suitable for small-scale rural water supply. The pilot-scale filter unit was made from an oil drum and consisted of two parts: a coarse-media (broken stones) contact filter for aeration and a sand-gravel matrix filter for the removal of insoluble iron and manganese salts. At a filtration rate of 0.7 m/h (3 l/min) iron and manganese removal was over 90%, reducing iron levels of 4.2-5.5 mg/l to less than 1.0 mg/l, and manganese from 1.2-1.7 mg/l to less than 0.5 mg/l. Although total coliform removal efficiency exceeded 96%, it did not satisfy water quality standards. If operated for 4 hours every day, the unit is capable of supplying 700 litres of water a day, sufficient for 30 people.
