To study the effect of aeration mode to the wastewater treatment process for pig breeding process affier process treatment anaerobic by means of SBR (Sequencing Batch Reactor) indicated that aeration mode did not affect to the COD removal efficiency, in all 3 research modes. COD removal efficiency is relatively high, reaching about 90 percent. Time for the nitrification performance of the tests is 12 hours. However, the effect of this stage is 6 hours. Ammonium oxidation efficiency reached in about 90-99 percent. Aeration mode 6 hours for one batch, a batch of 12 hours which includes two anoxic cycles- the aerobic showed high efficiency and stable with COD and T-N.
