Abstract


Waste water treatment with submerged attached growth processes (biofilm processes) using  microorganism to eliminate organic material is commonly used for organic waste water. Anaerobic-aerobic combination system can maximize the treatment efficiency. The major advantages of submerged attached growth process are their relatively small space requirement, the ability to effectively treat dilute wastewater, no sludge settling issues, also for many processes solids filtration occurs to produce a high quality effluent. This research using submerged attach growth installation on laboratory scale with five variation of time such as 340 minute, 680 minute, 1360 minute, 2266 minute, and 3400 minute. The treatment can decreased BOD 6,8% in 340 minutes, 41,56% in 680 minutes, 57,49% in 1360 minutes, 76,72% in 2266 minutes and 85,25% in 3400 minutes. It also reduced Phospat 14,22% in 340 minutes, 16,56% in 680 minutes, 43,19%  in 1360 minutes, 44,67% in 2266 minutes and 68,54% in 3400 minutes.
