Sewage sludge can be reduced, but not fully eliminated. 

Current dewatering technologies can hardly increase the dry solid content of sludge more than 20-25%.
Therefore, it is important to develop an innovative dewatering process capable to increase water removal from sludge,
in order to lower the mass of sludge to be transported to final disposal/recycling sites
and increasing its calorific power for incineration.
Electro-osmosis, forcing water molecules to move out from sewage sludge when dragged by an applied electrical field, appears an energy efficient alternative solution to current technologies to bring sewage sludge up to 45-50% dry solid content.

The main scope of the SLUDGEtreat project is to prolong the life cycle of sewage sludge, by:

1) Improving sludge quality

2) Increasing the percentage of sludge dry matter up to 50% for high added-value re-uses 
(i.e. as energy, biomass), other than fertilizers


The research activity of the Consortium of the project is focused on:

1) The study of the electro-osmosis process, resolving issues related to reliability, efficiency
(e.g.: process parameters and energy consumption) and LCA.

2) The design and development of a proof-of-concept electro-dewatering machine.

3) To investigate novel eco-friendly nanomaterials and coating techniques
able to minimize the corrosion of the anode.
