The Moving bed biofilm reactor (MBBR) system is the promising technology for the effective nutrient and organic removal from leachate in terms of achieving high nutrient removal efficiency by reducing the operating cost. Moving bed biofilm reactor (MBBR) technology has become popular in the field of leachate treatment because of its many advantages such as high capacity, high efficiency, relatively small footprints compared with the conventional treatment systems. MBBR is a continuous flow process where higher concentration of active biomass can be maintained for biological treatment without increasing the reactor size. The system is mainly based on the aeration and special designed carriers to provide a surface colonized by bacteria. For the growth of the microorganisms on the PE carriers, the MBBR system should be operated at favourable operating conditions by maintaining suitable carrier filling rate, aeration rate and HRT for the removal of DOC and NH4-N. At 20% filling rate the carriers moved uniformly and helped prevent the accumulation of excess biomass on the surface of the carriers as well as loss of biomass due to collision of the carries. Experimental results show that that the aeration rate of 4.5 L/min was favourable for the growth of active and effective microorganisms in PE carriers and gave higher nutrient and organic removal from leachate. The biomass concentration on the carriers increased with 2hr HRT. From experiments, it was demonstrated that the optimum operating condition for the effective nutrient and organic removal efficiency at 12 L volume of the reactor were; 20% of PE carrier filling rate by the volume of reactor, 4.5 L/min aeration rate and HRT of 2 h. The DOC removal efficiency at 20% PE carriers filling rate was found the highest and uniform (88.2%). The NH4-N removal was effective at 20% filling rate.
