【 摘 要 】

The removal of phosphorus and nitrogen in food wastewater previously difficult to removed. We investigated the removal of nitogen and phosphorus from food wastewater, especially tempeh wastewater. The ABR design was used using five baffled. This design was used to optimize the anaerobic process that occurs. Meanwhile, the RBC waste processors, using three stages with the shape of the surface of the disk used wavy and split. Selected design forms a disk surface as a contact medium with such special design, to optimize biofilm and oxygen transfer. This research was conducted in a laboratory scale. Operasional conditions for the units, by controlled the pH and varyed the load of nitrogen and phosphorus in the food wastewater. Removal eficiencies for total nitrogen was 91% and for total phosporus was 88%, respectively. However those removal eficiencies decrease with the increase in the N/BOD5 ratio of wastewater.
