Why is a deamination membrane preferred over an air-stripping tower for ammonia removal from wastewater?

Membrane deamination is a process that combines stripping and absorption in a membrane contactor to remove ammonia nitrogen from wastewater. It is highly efficient and has several advantages over the blow-off method:

1. Membrane deamination can remove up to 60-90% of ammonia nitrogen in a single stage, and up to 99% when two or three stages are connected in series, compared to the stripping tower which can remove 80-90% of ammonia nitrogen at best.

2. Membrane deamination is more energy-efficient as it operates at a low pressure and consumes less electricity than the blow-off method.

3. Membrane deamination is a closed system that does not release any harmful gases into the air, unlike the blow-off method which may cause atmospheric pollution.

4. Membrane deamination has a modular design that allows for easy adjustment of water processing capacity, making it highly flexible and adaptable to changes in water volume, while the stripping tower has a limited tolerance to changes in water volume.
