Processing of the liquid fraction

Gas permeable membranes / Contactors

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

Consumption
