Performance of Lagoon Ash As Bottom Liner in MSW Landfill
نویسندگان
چکیده
Proper management of Municipal Solid Waste dumping in landfill site require adequate bottom liner to mitigate the seepage leachate from contaminating ground. To make system sustainable, liners are provided at engineered system. Liners act as impermeable cover mitigating effect on ground and groundwater. Pond ash collected lagoon thermal power plant is a preferable building material for municipal solid waste impounding if properly stabilized compacted. meet mandatory requirement having permeability 10-7 cm/sec or less, detailed experimental study was carried out pond Nalco Captive Power Plant, Angul, India. The parameters Unconfined Compressive Strength (UCS) coefficient (K) were determined by conducting laboratory experiments following Indian standard code procedure all mixes stated Table 1. Experimental results UCS test found increase strength upto 5.4 MPa S3 mix sample after curing period 180 days. It further observed that S7 reached 6.9MPa which due binding 1% gypsum mix. hydraulic conductivity value Ash came down days even acid base permeation. R square established strong linear correlation existed between time value. clearly indicate ash, with optimum lime-gypsum satisfies both Environmental Protection Agency (U.S) Central Pollution Control Board (India) guidelines liner. Hence lime stabilised proved be an effective eco-friendly adhering requirements MSW

Impact of MSWI Bottom Ash Codisposed with MSW on Landfill Stabilization with Different Operational Modes
The aim of the study was to investigate the impact of municipal solid waste incinerator (MSWI) bottom ash (BA) codisposed with municipal solid waste (MSW) on landfill stabilization according to the leachate quality in terms of organic matter and nitrogen contents. Six simulated landfills, that is, three conventional and three recirculated, were employed with different ratios of MSWI BA to MSW. ...
متن کاملLeakage Performance of the GM + CCL Liner System for the MSW Landfill
The contaminants in the landfill leachate press pose a grave threat to environment of the soil and the groundwater beneath the landfill. Despite there being strict requirements in relevant provisions of both domestic and foreign countries for the design of the bottom liner system. Pollution of the soil and the groundwater still took place in a number of landfills because of the leakage. To inve...
متن کاملVitrification of Bottom Ash from A VR MSW incinerators
During incineration of municipal solid waste (MSW), various environmentally harmful elements and heavy metals are liberated either into bottom ash, or carried away with the off-gases and subsequently trapped in f ly ash. If these minor but harmf itl elements are not properly isolated and immobilized, it can lead to secondary environmental pol/ution to the air, soil and water. The stricter envi...
متن کاملSolubility and adsorption characteristics of Pb in leachate from MSW incinerator bottom ash.
The solubility and adsorption characteristics of Pb in leachate from municipal solid waste incineration (MSWI) bottom ash was studied by batch experiments. The solubility of Pb in leachate was 1-2 orders of magnitude lower than that of Pb in carbonate solutions. Adsorption experiments showed bottom ash have high adsorption capacity for Pb. To evaluate a controlling component in bottom ash, quar...
