CreChar® enhances the anaerobic digestion process of sewage sludge. This leads to higher biogas yield, less sludge, and less COD returned to wastewater treatment. In addition, CreChar® enhances process stability, which makes anaerobic stabilisation of sewage sludge less sensitive to changes in the organic and hydraulic load.
With CreChar®, water utilities can save costs on sludge treatment, produce more renewable biogas, and improve their climate impact. Moreover, after digestion and dewatering CreChar® remains part of the sewage sludge and increases its fertiliser value. This can make it easier for water utilities to secure current and new outlets for the sludge.
