LEACHATE-REVERSE OSMOSIS WATER TREATMENT
- Leachate is a liquid waste that is produced when the pollutants of solid wastes diffuse into the rain droplets and pollute the groundwater reservoirs.
- Leachate comprises a waste of a high pollution grade, if there is no prediction for treatment.
Leachates consists of:
- High organic load
- High concentration in heavy metals
- Non-biodegradable COD
- High concentration of ammonium ions
Leachates composition depends on the age of the Landfill and usually is stable in landfills of age 5-10 years old while a fully stable composition is achieved in landfills after 10 years of operation.
The tertiary landfill leachate treatment requires as a final step the application of reverse osmosis technology in order to produce good water quality. Permeate water meets the standards for reuse in irrigation and other uses (except potable water).
