Upflow Anaerobic Sludge Blanket (UASB) is a high efficiency anaerobic method to remove biocolloids and suspended solids in wastewater. In this study, the UASB install before constructed wetland system to remove river containments from farm wastewater and sewage. The UASB can remove suspended solid, zinc and copper at least 50% of the river water. The constructed wetland system can remove nitrogen and phosphate nutrient from the river water.
