| dc.description.abstract | Water is a renewable natural resource, are inseparable from human life in meeting daily needs.
Water consumed by humans need good quality and meets the standards of the health, which is Fe
level in drinking water should not exceed 0,3 mg/l. The aim of this research was intended to
determine the ability to reduce Fe in water from observation well through a filtration process using
charcoal filter material, sand and zeolite. The implementation is done by using individual filter
with a thickness of each 30-60-90 cm and for combination filter by using a combination of zeolitesand-
charcoal and sand-charcoal-zeolite with a thickness of each 20-27,5-35 cm. The results
showed that individual filtration charcoal filter reduced the levels of Fe in the test specimen of
water better than sand filters and filter zeolite with the ability of 95,99% at 90 cm thick filter. Filter
combination of sand-charcoal-zeolite is capable of lowering the levels of Fe in the test specimen of
water of 81.6% on filter thickness of 35 cm. This research showed that the thicker the material of
the filter, individually or combination, the greater the ability of lowering the levels of Fe in the test
specimen of water. | en_US |
