Processing of the liquid fraction
Gas permeable membranes / Contactors
Objective
Capture and recovery of ammonia present in a liquid stream by gas-phase mass transfer through a hydrophobic membrane
Inlets
Liquid streams rich in N-ammoniacal
Efficiency
There are studies that show that up to 95% of the ammonia present in liquid and gaseous streams can be recovered. The pH is a crucial parameter with ideal values
Weaknesses
Requires pH adjustment;
Products
Acidic liquid solution rich in N-ammonia. If sulfuric acid is used, the product obtained will be ammonium sulfate.
Other outlets
Treated liquid effluent
