The generation of contaminated leachate remains an inevitable consequence of the practice of solid waste disposal in landfills. The collection and treatment of leachate have become common practice in order to prevent environmental pollution. Leachate treatment is highly dependent on the quality of leachate, which in turn is influenced by various factors including waste composition and operation...

one of the most important concerns in tehran municipal landfill is the production of leachate and its potential for water resources pollution, this study was undertaken to examine feasibility of biological and physico/chemical treating of high-strength landfill leachate that was collected from tehran municipal landfill. average cod of the leachate in aerobic submerged membrane bioreactor is 68...

The impact of thermal pollution of leachate from a post-coal mine heap on three macrophyte species: Phragmites australis, Typha latifolia, and Scirpus sylvaticus was examined over the entire vegetation season. Hydrological measurements showed that the temperature of the leachate was ca 50 °C at the site of leachate inflow and decreased to ca 15 °C at the end of discharge canal. The annual tempe...

Landfill leachate is an important pollution factor resulting from municipal landfill sites. Physical and chemical processes are the better option for pretreatment or full treatment of landfill leachate. This article presents a combination of pre-treatment method (coagulation and adsorption) for leachate collected from municipal solid waste open dumping site. Physico chemical characteristics of ...

Landfilling is the most commonly used method for solid waste disposal in Jordan. It is an important source of pollution, which can be displayed through analysis of data for climatic conditions, hydrology and geology of the country. The migration of gas and leachate from the landfill body into the surrounding environment present a serious environmental concern, which include groundwater pollutio...

As a developing country, protecting groundwater resources is extremely essential in Sri Lanka. Landfills are one of the main sources of water pollution. The filling of the Gohagoda disposal yard, takes place at a distance about 50m from Gohagoda water intake plant. In addition, there is several boreholes located close proximity of the landfill, which used for drinking and domestic purposes. A s...

An important advantage of using a short-term pre-aeration of municipal solid waste (MSW) with high organic fractions prior to landfilling is that it intensively decomposes a part of organic matter, especially easily biodegradable fractions in waste, and thus regulates the subsequent anaerobic degradation of MSW under landfill conditions, meanwhile conserving the bio-methane potential as much as...

Leachate pollution is one of the main problems in landfilling. Among the most problematic parameters in stabilized leachate are COD, ammonia, and color. The treatment technology that can be used may differ based on the type of leachate produced. Even after treatment, the effluent characteristics are always hard to comply with the discharge standard. Ozonation is one of the chemical processes th...
