How does the ammonia removal membrane/nitrogen removal membrane work?
SCI-NANO PTFE ammonia removal membrane/nitrogen removal membrane module is used to remove ammonia nitrogen. First, the pH of the wastewater is adjusted so that most of the ammonia becomes free ammonia NH3. Gaseous NH3 can pass through the micropores on the surface of the hollow fiber and enter the pipe from the wastewater in the membrane filament. In the acid absorption liquid, it is absorbed by the acid liquid and immediately becomes ionic NH4-. In this way, the NH4- in the wastewater will continuously turn into NH3 and migrate to the acid absorption solution. As a result, the ammonia nitrogen concentration in the wastewater continues to decrease until it reaches the standard that satisfies the customer; because there is only acid and NH4- in the acid absorption liquid, very pure ammonium sulfate ((NH4)2SO4 is formed, and it reaches a certain level after continuous circulation.
concentration, it can be recycled and reused. It has the characteristics of smaller footprint, low energy consumption, stable water output, high deamination efficiency, and low usage cost.
