Esmil have vast experience in the field of leachate treatment. From bench scale studies through to full scale plant operations, Esmil look to offer BAT (Best Available Technology) state-of-the-art membrane separation and dewatering processes.

The leachate treatment system consists of 2 major processes (main stage and polishing); and delivers sludge or dry solid cake (as an option), and a high-quality water stream suitable for process reuse or disposal.

Firstly, the Esmil leachate treatment process uses a MBR where microbes are used to degrade pollutants which are filtered by a series of UF membranes in the second stage. Permeate is treated using RO membranes to produce water suitable for reuse or discharge to the local sewer.

Alternatively, fouling resistant vibrating membrane are used to treat the digestate (VSEP – Vibratory Shear Enhanced Processing). The Leachate waste will have elevated suspended solids along with other soluble contaminants. This will cause serious operational issues for standard membrane systems as they are prone to fouling. VSEP technology causes high shear forces at the membrane/fluid interface greatly reducing the risk of fouling.

High shear processing keeps membrane pores available for maximum removal of water (permeate). The concentrate retained (retentate) will contain the majority of pollutants from the feed and can be sent to evaporation ponds, evaporators, incineration or returned to landfill. The final stage of leachate treatment is the use of reverse osmosis membrane technology. This acts as a polishing stage further treating the permeate (treated water) from the VSEP units.
