Corrective action at a hazardous waste unit
Troy Risk performed a RCRA Corrective Action at a closed hazardous waste landfill for a multinational landfill company. The work involved inspection and cleaning of two 85-foot leachate risers. A leachate riser is a stack of 4-foot diameter concrete pipe sections, which provide a passage to the bottom of the hazardous waste landfill. The riser provides access to pumps and electronic leachate ...

Ontario Landfill Site - Case Study
A Texas based company with waste management sites around North America have installed electrical generation plants at various locations that use methane collected from the waste. The daily operation of these sites include the management of the leachate, a liquid waste by-product of decomposition, and the collection of gas for electricity production. This is typically carried out at multiple wells ...

Effects of mixed liquor pH on membrane fouling and micro-pollutant removals in membrane bioreactors for municipal landfill leachate treatment
This research investigated the membrane fouling and micro-pollutant removals in treatment of municipal landfill leachate at various pH levels (i.e. 5.5, 6.5, 7.5, and 8.5) using membrane bioreactors. The findings revealed that membrane fouling was influenced by the pH level of mixed liquor, with pH 5.5 exhibiting the most severe membrane fouling. At pH 5.5, proteins and carbohydrates were ...

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 ...

Lysimeter comparison of the role of waste characteristics in the formation of mineral deposits in leachate drainage systems
A common operational problem in leachate collection systems is clogging due to the formation of deposits within pore spaces and collection pipes. The role of co-disposal of municipal solid waste (MSW) and combustion residues from waste-to-energy (WTE) facilities in clogging is evaluated in this paper. Five parallel lysimeters were operated in monofill or co-disposal mode using MSW, WTE combustion ...

Electrocoagulation for Landfill Leachate Waste Water Treatment
Humans produce excessive amounts of waste. According to the EPA’s Advancing Sustainable Materials Management fact sheet, in 2015 the total amount of municipal solid waste produced in the United States was 262.4 million tons. On a per capita basis, 4.48 pounds of waste was produced per person per day in 2018. That trash consisted of paper, glass, rubber, plastic, metals, food, and textiles among ...

Materials recovery from waste cathode ray tubes (CRTs)
Executive summary ObjectivesThis is the second interim report of this project being carried out by ICER with support from Glass Technology Services. The project is examining potential markets for waste CRT glass. In this second stage five potential applications have been investigated, three for screen glass which does not contain lead and two for lead-containing funnel glass or mixed glass. The ...

Investigation on Potential Groundwater Impacts and Influence of Local Hydrogeology on Natural Attenuation of Leachate at a Municipal Landfill
The influence of local hydrogeology on natural attenuation of contaminants from landfill leachates in shallow aquifer underlying the active Olusosun landfill base in Lagos was investigated. In addition, the level of groundwater contamination in the vicinity of the landfill and of leachate migration pattern in groundwater down gradient of the landfill base was equally assessed. Landfill leachate ...

Toxicity Testing of Solidified Waste Leachates with Microbiotests
Abstract : Solidification is a process for treating contaminated wastes that reduces or entirely prevents the release of hazardous waste compounds into the environment. This process aims to make materials either not harmful nor toxic at all or at least less hazardous than the raw waste. The most widely used basic materials for solidification are cement, lime, fly ash, and blast-furnace slag. No ...
