The removal of ammonia from sanitary landfill leachate using a series of shallow waste stabilization ponds
This study evaluated the efficiency of a shallow (0.5 m deep) waste stabilization pond series to remove high concentrations of ammonia from sanitary landfill leachate. The pond system was located at EXTRABES, Campina Grande, Paraiba, Northeast Brazil. The pond series was fed with sanitary landfill leachate transported by road tanker to the experimental site from the sanitary landfill of the City ...

Membrane Bioreactor for Sanitary Landfill
The Problem The county of Warren NJ owns and operates a sanitary landfill in Oxford Twp, NJ. The facility generates an average of 50,000 gallons per day of leachate, with peaks to 100,000 gallons per day. The facility was discharging to a local POTW from their lagoon, but they were facing requirements for nitrogen removal from the POTW and needed a new system to provide the required treatment. ...

Kinetic study of toxic pollutants decomposition by ozone in landfill leachate using a numerical adaptive method
This study describes a new method to perform the kinetic study of toxic pollutants decomposition by ozone in landfill leachate using a novel numerical adaptive method based on the classical least square method. The leachate was obtained from the Mexico City waste sanitary landfill (Bordo Poniente) and was treated by ozonation after a coagulation treatment with Fe2(SO4)3. For the partial ...

Consortia of microalgae and bacteria in the performance of a stabilization pond system treating landfill leachate
This study treated sanitary landfill leachate and was conducted in a pilot-scale system composed of three serial ponds (P1, P2 and P3), followed by a rock filter, in order to evaluate the microbial consortium influence on system performance and to investigate microorganism dynamics in the process. The system was broken into three stages, with a continuous flow rate (Q = 200 L d−1) ...

Effect of leachate recirculation on refuse decomposition rates at landfill site: a case study
In this study, a comparison of methane (CH4) generation rates for two test cells, one operated with (enhanced) and another without leachate recirculation at Odayeri Sanitary Landfill were compared using their bio-chemical methane potentials (BMP). Initial methane potential is approximately 34.5 m³ CH4/wet ton of solid waste. The remaining methane potential for the control (C1) and the enhanced ...

Quantitative leachate estimation from a pilot-scale lysimeter study
Sanitary landfilling is the most important component of waste management. One of the main concerns is water contamination by leachate. This paper presents the outcome of the research on the water management of landfill in Nepal. The related leachate production as an effect of climatical factors is assessed. The Hydrologic Evaluation of Landfill Performance (HELP) computer model has been used to ...

How Does a Modern Landfill Work
In many people’s minds, landfills are dirty and smelly, sewage is flowing, and flies are flying around. In fact, this is a false impression. A true sanitary landfill has a set of strict standards, starting with garbage entering the site. From landfill to comprehensive use, every process is not simple. There are more than 400 million urban residents in my country, and more than 150 million ...

Enhanced stabilisation and methane potential of MSWs in a field-scale landfill with leachate recirculation
This study was carried out on two field scale test cells constructed at Odayeri Sanitary Landfill (OSL) located at the European side of Istanbul city. Approximately 11,000 tons of municipal solid wastes (MSW) were filled at equal quantities to each cell (C1 and C2). Leachate was periodically recirculated to one (C2) of the test cells in various quantities. These cells are compared in terms of ...

Characterisation and treatment of leachates from the municipal sanitary landfill of Thessaloniki, Greece
The optimum treatment technologies of leachates produced from a municipal landfill were studied in this work. Leachates composition ranged from high-strength acidic down to low-strength stabilised leachates, affecting the applicable treatment process. Efficient treatment of fresh leachates was achieved by biological methods, such as the SBR, or the moving bed processes, resulting in increased ...

Leachate Treatment
We pride ourselves in our membrane technology that effectively and reliably yields clean, reusable water. Our drive and dedication to clean industrial solutions has made us a top competitor in the industry, allowing us to apply our membrane technologies to many different fields. A typical sanitary landfill site When solid waste degrades and is soaked in precipitation, a black liquid called ...

Post-treatment of sanitary landfill leachate by coagulation–flocculation using chitosan as primary coagulant
Chitosan was chosen as an alternative primary coagulant in a complementary coagulation–flocculation treatment of sanitary landfill leachate with the aim of removing recalcitrant organic matter. In order to optimize the process conditions, central composite design and response surface methodology were applied. To evaluate the performance of the process using chitosan, we also carried out tests ...

How Much does a Landfill Liner Cost?
With my country’s emphasis on environmental protection and the gradual improvement of people’s awareness of environmental protection, more and more daily waste landfills have appeared in people’s vision. Isolation is the top priority. Thus, it is necessary to be cautious when choosing smooth geomembrane and rough surface geomembrane. To save costs, choose HDPE geomembrane with ...

Wetland Biofilter System provides year-round, cost effective treatment to over 1.5 million litres of wastewater
The success of early surface flow treatment wetlands in Canada was limited by hydraulic blockages and oxygen limitation due to freezing. From 1991 to 1996, Dr. Edgar Lemon, with the Friends of Fort George, researched a sub-surface vertical flow constructed wetland treating lagoon effluent at Niagara-on-the-Lake, funded by the Ontario Ministry of Environment (MOE) and the United States ...
