One of the disposal methods of household wastes is landfil. In our country, 1 kg per person and totally 30 millon tons household
waste per day is producted. It is the responsibility of the municipalities to carry out collection and disposal of household wastes and there are 79 landfill areas present in our country. In terms of environment pollution, the most important subject is treatment of leachate at landfills. Leachate consists many of pollutes that arise from the contents of the household waste is formed with biological reactions when landfilling, water content of the waste and rain water coming from outside environment to the storage site. Collection and
treatment of leachate is important due to its content of high amount organic substances, nitrogenous compounds, heavy metals,
chlorinated organic and inorganic salts and its potential to cause pollution to soil and underground waters. The characteristics and
quantity of leachate varies for every landfill and depend on content of household waste, climate conditions, structure and depth of
landfill area, structure of surface cover and operation properties. Leachate is the most difficult waste water for treatment because of
high contaminant properties. In this respect, generally, a combination of physical, chemical, biological methods and adsorbtion and
membrane technologies from advanced treatment methods are used for leachate treatment. In this study, IZAYDAS Solid Waste
Landfill Area where Kocaeli province’s solid waste is stored, leachate treatability with biological-chemical and submerged MBR
processes is utilized and compared with full scale MBR Treatment Plant treatment efficiency and all these have been evaluated.
Prototypes are not laboratory scale, but in the size of a small treatment facility and this way, it is aimed to provide close to real results
and in addition, operational problems are identified.
