LEACHATE-REVERSE OSMOSIS WATER TREATMENT

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).
