Faced with the rise in the production of sludge and the increasing difficulty in eliminating it (costs, regulations), SUEZ implements techniques that reduce the volume of the sludge and recover biogas.
The anaerobic digestion processes developed by SUEZ offer a number of advantages:
Reduced quantities of sludge
Depending on the process used, volumes can be reduced by up to 50%.
Increased dry content
Certain innovative processes can increase the dry content by 5 to 10 points compared with conventional digestion.
Sludge conditioning reduces olfactory nuisances and encourages hygienation.
Recovery of the sludge as green energy by producing biogas
SUEZ offers innovative technologies that can as much as double the production of recoverable biogas compared with conventional digestion.
SUEZ can offer proven processes that are constantly improved and that effectively meet your need to digest the sludge produced by the treatment of wastewater.
Depending on the quantity and the nature of the sludge (biological, mixed, etc.), different types of digestion are possible:
