Treatment of leachate from municipal solid waste landfill
Leachate from landfill is wastewater, which is accumulated on the bottom of a compartment or a landfill. The composition and the hydraulic flow of this water depends on the type of waste which was stored, the annual and momentary precipitation and last but not least the age of the landfill.
Older landfills drain less biodegradable organic matter (BOD/COD relation to zero). Typically pollutions can be high nitrogen concentrations (NH4, N02, N03, various hydrocarbons – often organ halogens, chlorides, sulphates, different heavy metals
(i.e. Zn, Cu, Ni, Cr, Cd, Hg, Pb and more)
The water usually shows less turbidly, it has a less brown color and mostly a penetrating smell can be detected. So in short: it is highly polluted, it has fluctuating hydraulics and it requires various process technologies to meet the effluent requirements, according to the local regulations.
Customer:
AVE – Alte Schanze, Germany is a landfill with production residues (i.e electroplating, fuel ashes), urban, oily and construction waste. Beside has an older area with different harmful residues, arised back to the year 1979 restriction and law.
Out of the landfill body are draining around 200.000 m3 leachate per year, which are collected and they need to be treated. The old wastewater system was not able to reach the effluent requirement. A new system was called for tenders.
After a selection period finally PPU was submitted for engineering, procurement and construction of the main part of the new waste water system.
Why PPU was selected? What are the advantages for the client:
We could offer out of one hand our standard ClearFox containeriSed treatment modules by looking back on more than 25 years experience of industrial wastewater.
The process technology suggested from PPU was validated by external consulting offices. All modules have been before approved externally, the pre-casted modules had finally the best price/quality relation in comparison to our competitors all over Europe.
