Semi-aerobic Landfill Project for CDM at a Malaysian Landfill Site

Landfill Site Selection

In terms of the Integrated Waste Management approach, progressive authorities are making concerted efforts to reduce the amount of waste that goes to their landfills for final disposal. Notwithstanding this, waste disposal by landfill remains the way in which almost all waste in African and other developing counties is currently disposed. This is also the case in many developed countries. Conse...

Combined anaerobic-aerobic treatment of landfill leachates

As a first step of treatment of landfill leachates (total COD – 1,430-3,810 mg/l, total nitrogen 90162 mg/l), a performance of laboratory UASB reactors has been investigated under mesophilic (30 C), sub-mesophilic (20 C) and psychrophilic (10 C) conditions. Under hydraulic retention times (HRT) of around 7 h, when the average organic loading rates (OLR) were around 5 g COD/l/day, the total COD ...

Aerobic biological treatment of landfill leachate

There is an ongoing need to treat leachates from landfills using approaches that avoid expensive installation and operating costs. Faced with such a problem, Powys County Council (Wales, UK) developed a treatment system based on practical experience. Leachate was re-circulated through aeration towers containing a biofilm supported on plastic media before being polished in reed/filter beds. Inve...
