Mature landfill leachate was anaerobically co-digested with synthetic wastewater to evaluate the degradability and methane productivity in various mixing ratios. The proportion of leachate was increased in three equal steps from 0% to 100%, and then decreased again through the same steps back to 0%. Both COD removal efficiency and methane production decreased as the leachate proportion in the i...

Combined treatment of landfill leachate and municipal wastewater was performed in order to investigate the changes of leachate toxicity during biological treatment. Three laboratory A2O lab-scale reactors were operating under the same parameters (Q-8.5-10 L/d; HRT-1.4-1.6 d; MLSS 1.6-2.5 g/L) except for the influent characteristic and load. The influent of reactor I consisted of municipal waste...

Landfill leachate contains heavy organic pollutants, which pollute ground and surface waters. This dataset applied a newly-introduced catalyst, Cu/Mg/Al-chitosan, for a landfill leachate treatment during a catalytic oxidation. The data of chemical oxygen demand (COD) and colour removal from the leachate was reported as a function of reaction time (20-460 min). Economic evaluation data of the Cu...

Municipal waste management is still a significant problem for solid issues in Indonesia. Only 60 to 70% of the generated disposed landfills, rest dispersed different areas. The potential leachate pollution, greenhouse gases, and non-renewable natural resources can occur due municipal problems not being optimal. needs holistic concept that would include upstream downstream stages. This paper com...

Eutrophication, a major problem in many fresh and brackish waters, is largely caused by nonpoint-source pollution by P from agricultural soils. This lysimeter study examined the influence of P content, physical properties, and sorption characteristics in topsoil and subsoil on P leaching measured during 21 mo in 1-m-long, undisturbed soil columns of two clay and two sandy soils. Total P losses ...

This study demonstrates the influence of lysimeter operational condition and tropical seasonal variation of leachate characteristics generated from municipal solid waste (MSW) deposited in landfill lysimeter at KUET campus, Bangladesh. Three different situations of landfill were considered here as well as both the open dump lysimeter-A having a base liner and sanitary landfill lysimeter-B and C...

Landfill leachates are often treated on-site before disposal to municipal wastewater treatment plants, although variations in leachate composition and organic loading continue to have negative impacts on downstream treatment processes. Leachate samples were collected from four landfills both before and after on-site treatment to evaluate the extent of biological treatment. The samples vary in a...

Open dumping activities at the Batu Layang TPA can potentially cause leachate pollution to environment. Leachate that seeps into ground contaminate groundwater. Most people around use groundwater for MCK (bath, wash, toilet) purposes. If is contaminated with and used sustainably by community, it will impact health problems. Therefore, necessary manage distribution of leachate. One management sy...

In the landfills of municipal solid wastes there are a number of constituents which will leach under the influence of infiltrating water. Among the leached constituents there are also trace inorganics which are potentially hazardous to the environment, the most important being the heavy metals. It follows that the waste landfills have a high contamination potential in terms of heavy metals, bec...
