Abstract

The high rates of urbanization and the rapid development in urban areas causes the more densely populated that require water in large enough quantities. Water that has been used by the people in general is thrown back into the waterbody or river under conditions that have been contaminated (wastewater), so it would pollute the riverwater, while at the downstream area peoples still use the riverwater for daily use. To overcome this problem we need a model of how wastewater purification performed before wastewater is channeled into the river. This study aims to plan a Purification model for community wastewater before it channeled into the river, to find out how much the rate of decrease in turbidity of the riverwater after passing through the filter water purification, and to determine the effect of water level that flows in the channel of the river onto the discharge of wastewater out past the filter. By using the experimental method in the laboratory of Hydraulics, made a physical model of the river where the bottom line sand filter fitted with a thickness variation of 4cm, 8cm, 12cm, 16cm, and 20cm on the gradation of 2.3mm, 1.8mm, and 1.5 mm pipes connected to the source of wastewater. The results showed that the model used wastewater treatment can reduce wastewater turbidity to 30-40 %, and the height of the riverwater flowing on give effect onto the purification of wastewater discharge out past the filter.
