BACKGROUND When the unavoidable waste generation is considered as damaging to our environment, it becomes crucial to develop a sustainable technology to remediate the pollutant source towards an environmental protection and safety. The development of a bioengineering technology for highly efficient pollutant removal is this regard. Given the high ammonia nitrogen content and chemical oxygen dem...

The improper treatment of landfill leachates is one the major problems associated with waste landfilling and causes serious environmental pollution at sites their surroundings. To develop a suitable leachate system to minimize risk pollution, it important characterize seasonal temporal variations leachates. This study investigated quality Nam Son in Hanoi, Vietnam 2017–2019 characterized potent...

background: untreated leachate is being discharged into the environment in many countries worldwide. leachate treatment methods have not been unified so far due to the variable composition of leachate. moreover, the lack of appropriate treatment and disposal of leachate causes environmental pollution. this study aimed to compare removal efficiency of chemical oxygen demand (cod) and total suspe...

Many of the landfills may contain xenobiotic compounds including monoaromatic hydrocarbons and halogenated hydrocarbons, which are well documented to have negative effects in the aquatic environment and are resistant to biodegradation. In this research, landfill leachate was treated by combined advanced oxidation and suspended fiber biofiltration. Advanced oxidation destructed xenobiotics in th...

Tujuan dari penelitian adalah untuk mendeskripsikan kualitas dengan parameter DHL, pH, BOD, COD, Zn menganalisis tanah, dan mengevaluasi hubungan antar tanah di sekitar Sukawinatan. Pengambilan sampel dilakuk...

This study investigated two methods for the removal of COD and colour from sanitary landfill leachates. The first method involved the use of coagulation/flocculation process using FeCl3 as a conventional coagulant and Ca(OH)2 as base-precipitant. The second method involved integration of Fenton’s reagent into the coagulation/flocculation process. Concentration of FeCl3 that reduced chemical oxy...

Field weathering of spent mushroom substrate (SMS) produces soluble compost leachate that percolates into underlying soils and may adversely impact groundwater. Laboratory experiments were conducted to investigate movement and retention of SMS leachate solutes in subsurface soil columns. Spent mushroom substrate leachate with high concentrations of dissolved organic matter (DOM) and inorganic s...

In this paper, a statistically-based experimental design with response surface methodology (RSM) was employed to examine the effects of functional conditions on the photoelectrocatalytic oxidation of landfill leachate using a Cu/N co-doped TiO2 (Ti) electrode. The experimental design method was applied to response surface modeling and the optimization of the operational parameters of the photoe...
