Landfill leachate treatment for Indonesia

The plant constructor WEHRLE with headquarters in Emmendingen in the South-West of Germany has obtained the contract for the design, construction and commissioning of a leachate treatment plant for the treatment of highly loaded leachate from a municipal solid waste landfill in Jombang on the Indonesian island of Java.

For this purpose, WEHRLE will be using a special Membrane Bioreactor (MBR) technology based on the proven BIOMEMBRAT^® process. This high-performance plant has proven its reliability for the treatment of non-biodegradable wastewater over decades. Special external ultrafiltration membranes ensure a particle-free discharge and avoid the generation of concentrates. The compact design also takes into account the difficult local conditions, such as the risk of earthquakes and tsunamis.

The WEHRLE MBR plant will be integrated into a plant concept determined by the Ministry. The plant design takes up the smallest area of the overall concept, yet treats 75% of the daily leachate volume of 300 m³ to direct discharge quality.

Together with the three projects in Jambi, Malang and Sidoarjo, this is WEHRLE’s fourth reference in Indonesia. The project in Jombang is funded by the KfW banking group (“Kreditanstalt für Wiederaufbau“) within the ERiC (Emission Reduction in Cities) project series.

“We are happy to make an important contribution to modern and sustainable environmental protection in this region with our highly efficient and economic plant technology“, says Simon Götz, Area Manager for Asia.
