ABSTRACT
There are so many leachate produced by solid waste landfill which is not required by effective leachate treatment unit. The purpose of this study is to know the removal efficiency of COD, TN, and TSS, and also the optimum HRT using Anoxic Aerobic Moving Bed Biofilm Reactor MBBR . MBBR is a biological processing unit that combine attached growth system with suspended growth system. The MBBR 39 s operational system that used in this study is batch system. HRT that used in this study is 12 and 24 hours. COD, TN, and TSS concentrations of Cipayung landfill leachate is in range 3345 mg L ndash 6000 mg L, 2285 mg L ndash 2585 mg L, dan 650 mg L ndash 2155 mg L resepectively. The removal efficiency of COD, TN, and TSS with 12 hours HRT as result of this study is in range 59.47 66.58 , 58.87 70.50 , dan 51.72 54.79 respectively. And The removal efficiency rof COD, TN, and TSS with 24 hours HRT as result of this study is in range 62.48 69.99 , 70.23 83.56 , dan 53.33 ndash 61.17 respectively. The optimum time detention HRT of this study is 24 hours. The small value of removal efficiency causes the leachate concentrations still exceeds the quality standard.

This research was carried out to investigate the efficiencies of leachate treatment by using subsurface flow constructed wetland (CW) with low permeable reactive media and guinea grass (Panicum maximum TD 58). Pilot scale CW was examined at hydraulic loading rate (HLR) of 0.028 m/d and hydraulic retention time (HRT) of 10 d. Two different types of media in CW were used i.e. system 1: clay and sand mixture at ratio of 40:60 (%w/W) and system 2: clay, iron sludge and sand mixture at ratio of 30: 10:60 (%w/w). The results showed that the performance of system 2 was better in terms of pollutant removal efficiencies. Average BOD, COD and TKN removals were 76.1, 68.5 and 73.5% respectively. Methane, carbon dioxide and nitrous oxide emissions during the treatment of CW were 23.2-52.1, 69.1-601.8 and 0.04-0.99 mymzd respectively. The use of CW with reactive media in system 2 and vegetation resulted in lower GHG emissions. The results show that CW with low permeable reactive media could be effectively used to remediate leachate from the landfill site.

The Quezon City Controlled Dumping Facility (QCCDF) has been the ‘main disposal site of Quezon City, the largest city within Metro Manila since the 1970s. With the huge volume of wastes received every day and with no protective liner on the old mound and creeks directly connecting the facility to Marikina River, the main river system in eastern Metro Manila, surface and groundwater contaminations have been a critical concern. The main objective of the study is to determine the effect of the disposal site on the surface water and groundwater quality by evaluating the water quality at different points in and around the landfill. Secondarily, it aims to investigate correlations between the water quality parameters as well as determine any seasonal effects on the water quality. Sampling points from wells on and around the facility were collected for six months covering dry and wet season using Horiba water quality monitoring equipment and CHEMetrics V- 2000 Photometer. Leachate quality parameters pH, turbidity, DO, and chloride are not affected by the change in seasons as evidenced by statistical t-tests. Temperature is higher during the wet season, while TDS is lower at this time which may be attributed to dilution due to rainfall. DO and turbidity in leachate is strongly negatively correlated, while temperature and C1‘ in leachate are positively correlated. In groundwater, the change in season affects temperature, TDS and chloride concentrations. This trend is not evidenced in pH and turbidity. TDS and chloride are correlated with each other. Based on the surface water quality measurements, temperature, pH, DO, and TDS are affected by the change in season while turbidity and chloride are not, based on the comparison of samples taken from different locations. Aside from strong correlation of Cl’ and TDS, as seen in groundwater, very strong correlations are also observed between Cl’ and DO, and TDS and DO. Using chloride ion as indicator of leachate, the study reveals that the leachate tends to spread downward towards Marikina River. Based on the comparison of chloride concentrations near the outfall of the leachate creek at Marikina River, it can be seen that the release of leachate at the river impacts the river as evidenced by an increase in chloride concentration downstream of the outfall.
