Landfill Seepage Treatment

Several different processes are used in the treatment of water seeping from landfills. In addition to such techniques as biological treatment, precipitation/flocculation, chemical oxidation, reverse osmosis and vaporisation, activated carbon adsorption now plays a major role as well.

Powdered activated carbon is seldom used in newer facilities. In most cases, granular activated carbon is used in fixed beds, followed by reactivation.

Adsorption is often employed following other pollutant-reducing treatments, which increases the effectiveness of the activated carbon process. Adsorption removes COD compounds and AOX compounds, which are not readily biodegradable. Achievable pollutant loads depend primarily on the influent concentration.

Recommended AC Qualities:
Donau Carbon GC 840P
Hydraffin 30N
