Mathematical modelling of landfill gas migration in MSW sanitary landfills

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2001
The laws that govern the displacement of landfill gas in a sanitary landfill are analysed. Subsequently, a 2-D finite difference flow model of a fluid in a steady state in a porous medium with infinite sources of landfill gas is proposed. The fact that landfill gas is continuously generated throughout the entire mass of the landfill differentiates this

Sanitary Landfill Types and Design

, 2022
In terms of solid waste management, landfills are the favored disposal strategy. Before an area is established as a landfill, certain crucial things must be focused on and acted upon.

Behavior of Radionuclides in Sanitary Landfills

Health Physics, 1984
his study was undertaken to evaluate the possibility of disposing low-level radioactive waste in sanitary landfills with leachate containment to prevent environmental releases. To meet this objective, two simulated landfills, each 200 l. in volume and containing 55 kg of municipal refuse, were operated in the laboratory with simulated rainfall ...

Economic analysis of landfills : sanitary landfills vs bioreactor landfills [PDF]

, 2022
With increasing public awareness of the environmental consequences of landfill operations, traditional Municipal Solid Waste (MSW) landfill technology, referred as sanitary landfilling, are facing formidable challenges. Local governments, municipalities and waste professionals are seeking more environmental-friendly alternatives to dispose of MSW by ...

The Sanitary Landfill in the Subarctic

ARCTIC, 1972
A field study of two and a half years was conducted into the application of the sanitary landfill to the Subarctic. Temperatures and gas concentrations were observed in an experimental cell, and groundwater quality measured on the periphery. Carbon dioxide concentrations peaked during the warmer periods corresponding to minimum oxygen concentrations ...

Future of Sanitary Landfill

Journal of the Environmental Engineering Division, 1975
This paper offers and examines a new policy which, upon adoption, could: (1) Reduce people's objection to sanitary landfill as a neighbor; (2) significantly increase the amount of land eligible for use as sanitary landfill; (3) reduce to some degree inequity between rich and poor; and (4) provide a more desirable land-use policy.

Treatment and detoxification of a sanitary landfill leachate

Chemosphere, 2004
The leachate from an old sanitary landfill (Gramacho Metropolitan Landfill, Rio de Janeiro) was characterized and submitted to coagulation and flocculation treatment followed by ozonation and ammonia stripping. The performance of the treatment was assessed by monitoring the removal of organic matter (COD and TOC), ammonium nitrogen and metals ...

Enzymatic treatment of sanitary landfill leachate

Chemosphere, 2001
The objective of this investigation was to study the effectiveness of applying enzymes (bioaugmentation) for enhancement of biological treatability of leachates generated in a typical municipal solid waste sanitary landfill. The basic purpose of enzyme use is to enforce the biodecomposition of organic constituents, as well as to reduce nitrogen content.

A model for sanitary landfill management and design

Computers & Operations Research, 1974
Abstract A general discussion of a mathematical model designed to aid in the management and design of a sanitary landfill is given. This includes a description of the development of input variables for the model which are developed through a computer aided design process. Then a set of equations and constraints that describe the operation of the site

FUTURE OF THE SANITARY LANDFILL

Journal of the American Medical Association, 1954
On Dec. 15, 1952, the First National Conference on Trichinosis made it clear that the widespread practice of feeding raw garbage to swine was the major link in the transmission of trichinosis. Between then and now, in a period of little more than a year, there has been a truly spectacular rate of adoption of acts by state legislatures, by which feeding
