The Principle of Reverse Osmosis Applied to Leachate Treatment
When leachate must be treated to a very high standard for watercourse discharges which require not only for the reactive components of leachate to be removed but also require non-reactive compounds to be removed such as the sodium chloride, which is always elevated in MSW landfill leachate, the technology of Reverse Osmosis may be the […]
How Do You Treat Leachate?
First of all when asked the question, “How Do You Treat Leachate?”, we would like to make a distinction between true treatment which involves converting environmentally damaging substances to less, or non-toxic, ones, and simply concentrating the contaminants from the water in leachate to give a volume reduction. In the water industry both are known as […]
Anaerobic Digestion of Landfill Leachate for Energy Generation: Pipe-Dream or an Opportunity?
Anaerobic digestion is becoming increasingly popular in this age of high energy prices, and many more people are realising that whereas aerobic treatment systems consume large amounts of expensive energy, anaerobic digestion is a process which does the opposite. In fact it produces a net energy output. It is not surprising therefore, that many […]
Wastewater Treatment in Wetlands: Contaminant Removal Processes
An Introduction to Wastewater Treatment in Wetlands Originally published by U.S. Department of Agriculture, Cooperative Extension Service, University of Florida Wastewater treatment in wetlands can be highly effective, [including for leachates]. Wetlands are commonly known as biological filters, providing protection for water resources such as lakes, estuaries and ground water. Although wetlands have always served this purpose, […]
How Leachate Changes in a Landfill Over Time
Have you ever wondered why leachates can seem so different. Some leachate is cloudy, black, and smells strongly, while at other times it is fairly odorless and amber coloured?
