Analysis of landfill components in estimating the percolated leachate to groundwater using the HELP model
Landfills are one of the groundwater pollution sources in Gaza Strip. This study focuses on two landfills operating in Gaza Strip; the first is Dear Al Balah landfill which has a lining system and the second landfill is Gaza landfill which does not have a lining system. The main objective of the present study is to assess the effect of landfill components on percolated leachate to groundwater ...

Enhancing the hydrolysis step in anaerobic digestion of municipal solid waste using rumen fluid
Bench scale reactors were operated to optimise the hydrolysis rate of municipal solid waste (MSW) using daily and alternate day addition of 3%, 5% and 10% V/V of rumen fluid. Quantitative and qualitative analysis of leachate were practised daily. Cumulative pollution leaching, i.e. COD, TS, VFA and Amm-N, was comparatively higher with the daily addition of rumen fluid than the alternate addition ...

Hazard assessment of waste disposal sites. Part 1: literature review
A review of the literature and computer models from the perspective of hazard assessment approaches, particularly relating to the risk analysis of waste disposal sites, has been carried out. It was found that a comprehensive hazard assessment procedure covering all modules and sub-modules for landfill leachate does not exist. The same deduction also applies to landfill gas and degraded landfill ...

Distribution and removal efficiency of heavy metals in two constructed wetlands treating landfill leachate
The results of heavy metals (Fe, Mn, Zn, Ni, Cu, Cr, Pb, Cd) removal and partitioning between aqueous and solid phases at two treatment wetlands (TWs) treating municipal landfill leachates are presented. One of the TWs is a surface flow facility consisting of 10 ponds. The other TW is a newly constructed pilot-scale facility consisting of three beds with alternately vertical and horizontal ...

Analysis of leachates from solid waste dumpsites: a tool for predicting the quality of composts derived from landfills
Leachate and soil samples were collected near five solid waste dump sites in the Accra metropolitan area of Ghana over a period of six months. The leachate samples were analysed for heavy metals, coliform bacteria and helminth eggs while the soil samples were analysed for only helminth eggs. Heavy metals analysed included Cd, Pb, Zn, Mn, and Cu. It has been observed that the leachates contain ...

Study of colloidal content and associated heavy metals in landfill leachate: a case study of El-Akader landfill site: Jordan
Landfill leachate samples were collected anaerobically at six locations at the El-Akader landfill site in North Jordan. The collected leachate samples were separated into size fractions with special attention to the distribution of colloids and associated heavy metals. The fraction sizes were 1.2 µm. The maximum concentrations of heavy metals in the analysed leachate samples were Cd 0.6 µg/l, Ni ...

Capping of Coal Ash Landfill in Mallorca - Case Study
Project Details Capping of Coal Ash Landfill, C.T. Alcudia Location Mallorca, Baleares Islands (Spain) Products Used Resistex ST Cetcodrain 40X12-2 The increased use of coal to generate electricity has brought with it an increased amount of coal combustion by-products (CCBs). Metal ions released from these CCBs can be harmful to the environment and therefore need to be ...
