Influence of Hydraulic Conductivity and Moisture Retention Characteristics of Waste on the Performance of Leachate Recirculation System
Abstract Recirculation of leachate in bioreactor landfills accelerates the waste stabilization process. Due to biodegradation-induced changes in waste density, the waste parameters such as hydraulic conductivity and moisture retention characteristics (MRCs) evolve continuously within the landfill. I...

| 520 | |a Abstract Recirculation of leachate in bioreactor landfills accelerates the waste stabilization process. Due to biodegradation-induced changes in waste density, the waste parameters such as hydraulic conductivity and moisture retention characteristics (MRCs) evolve continuously within the landfill. In this study, an approach to evaluate the temporal variations of the hydraulic conductivity and MRC of waste is proposed, which is then used to simulate the changes in the hydraulic performance (wetted width, flow rate and injection pressure) of the leachate recirculation system. Simulations were carried out for ten years to demonstrate the effect of flow rate and pressure head on the propagation of the saturation contours within the landfill. The results indicate that for a constant flow rate, the wetted width and pressure head increase with the age of landfill. It also shows that the operational costs incurred due to the pumping of leachate can be decreased by reducing the flow rate gradually with time without reducing the wetted width. The implications of the study are demonstrated by considering a liquid injection system design for a landfill of one-hectare area. | ||

Abstract Recirculation of leachate in bioreactor landfills accelerates the waste stabilization process. Due to biodegradation-induced changes in waste density, the waste parameters such as hydraulic conductivity and moisture retention characteristics (MRCs) evolve continuously within the landfill. In this study, an approach to evaluate the temporal variations of the hydraulic conductivity and MRC of waste is proposed, which is then used to simulate the changes in the hydraulic performance (wetted width, flow rate and injection pressure) of the leachate recirculation system. Simulations were carried out for ten years to demonstrate the effect of flow rate and pressure head on the propagation of the saturation contours within the landfill. The results indicate that for a constant flow rate, the wetted width and pressure head increase with the age of landfill. It also shows that the operational costs incurred due to the pumping of leachate can be decreased by reducing the flow rate gradually with time without reducing the wetted width. The implications of the study are demonstrated by considering a liquid injection system design for a landfill of one-hectare area.

Due to biodegradation-induced changes in waste density, the waste parameters such as hydraulic conductivity and moisture retention characteristics (MRCs) evolve continuously within the landfill. In this study, an approach to evaluate the temporal variations of the hydraulic conductivity and MRC of waste is proposed, which is then used to simulate the changes in the hydraulic performance (wetted width, flow rate and injection pressure) of the leachate recirculation system. Simulations were carried out for ten years to demonstrate the effect of flow rate and pressure head on the propagation of the saturation contours within the landfill. The results indicate that for a constant flow rate, the wetted width and pressure head increase with the age of landfill. It also shows that the operational costs incurred due to the pumping of leachate can be decreased by reducing the flow rate gradually with time without reducing the wetted width. The implications of the study are demonstrated by considering a liquid injection system design for a landfill of one-hectare area.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Leachate recirculation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Unsaturated properties</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hydraulic conductivity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Wetted width</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pressure head</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hydrus-2D simulation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lakshmikanthan, P.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Vibha, S.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sivakumar Babu, G.

Influence of Hydraulic Conductivity and Moisture Retention Characteristics of Waste on the Performance of Leachate Recirculation System |
| abstract |
Abstract Recirculation of leachate in bioreactor landfills accelerates the waste stabilization process. Due to biodegradation-induced changes in waste density, the waste parameters such as hydraulic conductivity and moisture retention characteristics (MRCs) evolve continuously within the landfill. In this study, an approach to evaluate the temporal variations of the hydraulic conductivity and MRC of waste is proposed, which is then used to simulate the changes in the hydraulic performance (wetted width, flow rate and injection pressure) of the leachate recirculation system. Simulations were carried out for ten years to demonstrate the effect of flow rate and pressure head on the propagation of the saturation contours within the landfill. The results indicate that for a constant flow rate, the wetted width and pressure head increase with the age of landfill. It also shows that the operational costs incurred due to the pumping of leachate can be decreased by reducing the flow rate gradually with time without reducing the wetted width. The implications of the study are demonstrated by considering a liquid injection system design for a landfill of one-hectare area. © The Author(s), under exclusive licence to Indian Geotechnical Society 2022.
