Landfill is the most common way to eliminate municipal solid wastes. In general, landfills contain a mixture of materials which are highly inhomogeneous, in¬cluding a very high organic component as well as soluble mineral substances. This generates heavily polluted leachates, which arise primarily due to rainwater seeping through the landfill, and from the moisture of the waste itself. Also it can occur from groundwater ingress due to inadequately sealed landfill liners.
This presents significant variations in volumetric flow and chemical composition. Untreated leachate is hazardous to the environment if allowed to enter water systems, forcing government authorities to implement increasingly stringent regulations for pollution control and landfill wastewater treatment.
Normally it is sufficient to treat the landfill leachate to a quality that meets the standards so that it can be discharged to the nearest municipal wastewater treatment plant for further processing. Should this not be possible, it can be necessary to treat the leachate to meet the requirements for direct discharge into a river, stream or lake.
Precipitation, Flocculation, Dissolved Air Flotation, Ozone Treatment, Denitrification, Nitrification, Fuzzy Filtration, Activated Carbon Adsorption. The sludge goes to an existing gravity thickener and it is pressed.
Pictures of the installed system and processes
The wastewater can be led through several process steps. These can be like in the pictures above. The process is fully automatic and the daily flowrate, which is depending on the rainfall can be adjusted manually. All steps can be bypassed, and the flow can be reversed by manually switching valves (i.e. if more nitrate in raw water, then first denitrification, then nitrification)
The following effluents between the treatment steps are achieved.
