## Abstract
Abstract One of the simple, easy and inexpensive water treatment technologies is the Sand Filtration technology. Sand Filtration is one of the very small grains of sand as a filter media. This study is an experiment. The objective to be achieved in this study is to analyze the difference in the thickness of the sand filter media to the filtration speed and the amount of filtration discharge, which is the object of research is the raw water of the Departemen engineering Hasanuddin University with treatment using a long reactor 50 cm, width 50 cm and height 150 cm, Down Flow filtering method with sand thickness varies namely 20 cm, 30 cm, 50 cm, besides that it also uses 15 cm gravel and 5 cm fibers. Testing is done by screening, calculating the speed of water through the filter and checking the flow of water. The results were obtained with a thickness of 20 cm sand filtration media resulting in a filtration flow of 0,000199 m 3 /second with flow rate filtration 0,000794 m/second, a thickness of 30 cm sand filtration media resulting in a filtration flow of 0,000220 m 3 /second with rate filtration 0.00879 m/second while 50 cm sand produces filtration flow 0,000242 m 3 /second with rate filtration 0.00969 m/second. It can be concluded by increasing the thickness of the filtration media filtration discharge and filtration speed also increases.
