For introductory information concerning the specification of leachate plant please refer to the page "Leachate: Some Basic Facts".
Organics offers a variety of different types of leachate treatment system, each of which is available in different ranges to facilitate site specific requirements. Download our general datasheet on leachate treatment here.
The main technology headings are as follows:
Remove ammonia from leachate with a physical process, use can be made of landfill gas to heat leachate, or removal can be facilitated with pH adjustment.
Treat leachate by means of aerated lagoons that maximize simplicity, removing BOD, COD and ammonia.
Sequencing Batch Reactors
High-rate removal of ammonia with a biological sludge blanket, facilitating a reduced retention time and improved process control.
Activated Carbon Columns
Removal of AoX, polishing of COD and other selective removal of toxic trace components in leachate.
Evaporation offers the possibility of complete leachate destruction with the use of landfill gas or other sources of waste heat.
The difference between a “natural treatment” system, such as a reed bed, and a mechanised biological treatment system, such as a sequencing batch reactor, is that the former proceeds at natural rates without the use of significant amounts of energy input.
