How AmmEL-HC Works
AmmEL-HC is a patented ammonia removal process consisting of either strip and scrub columns or membrane technology linked to an electrochemical reactor. In the case of the strip and scrub approach, there are three phases: stripping ammonia gas from the wastewater, scrubbing the ammonia back into a liquid stream, and electrochemically converting the ammonia to free nitrogen gas.
The pH of the wastewater is increased before being pumped into the top of the stripping column. Air pumped into the bottom of the column transfers the ammonia from the wastewater to liquid in the scrubbing column. The scrubbing liquid is then transferred to the electrochemical reactor where the ammonia is converted to environmentally friendly nitrogen gas.
