Siemens to provide IPS composting system in China

Guodian Northeast Environmental Protection Industry Group, Ltd. has selected Siemens Industry Automation Division to supply an IPS composting system using the new Mechanically Enhanced Biodrying (MEB) process for the Shenyang Wastewater Treatment Plant Sludge Treatment Project in Shenyang, China. It will be the largest IPS composting facility ever built, and one of the largest sludge treatment processes in the world using non-thermal processing. The IPS system for Guodian in Shenyang will be used in a new sludge treatment facility that will serve three existing wastewater treatment plants and one new plant. The plants have been landfilling or land applying wet (20 percent solids) sludge. China recently passed a law that sludge must be a minimum of 60 percent solids for land application and/or landfill disposal.
