Siemens to provide composting system for China water treatment project


Siemens

Siemens Industry Automation Division has been selected by Guodian Northeast Environmental Protection Industry Group to supply an IPS composting system for the Shenyang Wastewater Treatment Plant Sludge Treatment Project in Shenyang, China.

The composting IPS system, which is scheduled for commissioning later this year, will serve three existing wastewater treatment plants and one new plant.

Using the new Mechanically Enhanced Biodrying (MEB) process, Siemen's composting system will dewater 1,000 wet tonnes of wastewater sludge per day from 20% solids to 65% solids in its first commercial application.

The company said MEB process provides a lower energy usage alternative to traditional sludge dryers for reducing the mass of sludge sent to the landfill.

The Government of China recently passed a law that sludge must be a minimum of 60% solids for land application and/or landfill disposal.
