| Abstract | Leachate is an important problem associated to solid waste management. It composes of wide ranges of biological and chemical materials. Contaminations of leachate in soil, groundwater, and surface water cause environmental damages and subsequent health impacts. Thus, issue concerning management of leachate generated should be taken into consideration for all of solid waste operation units. This study aims to investigate and recommend an appropriate leachate management system for further development and application at the ThaRaeng Transfer Station, Bangkok Metropolis. Details of leachate generation and its characteristic are analyzed together with the reported compositions of leachate from other stations. The advantages and disadvantages of various existing alternatives for management of leachate are gathered and discussed under items: (1) Land disposal. (2) Recycling and evaporation. (3) Combined treatment with domestic sewage. ( 4) Biological processes. (5) Physical and chemical processes. Based on leachate characteristics, potential leachate treatment technologies are aerobic biological process, including activated-sludge process, aerated lagoon, and stabilization pond. Through the developed guideline and criteria, the most practical treatment process for the station is aerated lagoon because it has high treatment efficiency and optimal system costs. Moreover, it is flexible to variations of lecahate characteristics and uncomplicated for system management. However, a physical or chemical posttreatment may be applied for eliminating heavy metals in final effluent. For effective development and application of the recommended process, further investigation and verification of data sets for design criteria are recommended. A pilot scale study would also increase applicability of the study results. |
