sludge treatment

Reading time:

As agri-food industries occupy a wholly integral part of the agricultural system, from the production of the raw material to its processing, the classic approach has been to recycle the sludge for agricultural land application. Typically, this sludge is usually well below the limits for heavy metals or dangerous pollutants.

The first step consists in dewatering this mainly biological sludge using the typical processes described in chapters liquid sludge treatment and dewatered sludge treatment.
