Ammonia Removal Membrane (PTFE-MBC-2040)

Anhui Sci-Nano has recently developed a deamination membrane device that utilizes a PTFE membrane contactor as its core. This device effectively utilizes the unique properties of the PTFE membrane, such as strong hydrophobicity, breathability, and impermeability. The operation of the device involves adjusting the pH value of the wastewater to an alkaline level. This adjustment allows the conversion of ammonia nitrogen ions in the wastewater into ammonia. As a result, a specific ammonia partial pressure difference is created on either side of the membrane. This difference enables the ammonia gas to flow from the wastewater side, with a higher partial pressure, to the absorption liquid side, with a lower ammonia partial pressure. The device successfully reduces the presence of ammonia nitrogen in wastewater, effectively achieving its intended purpose.

Product Description

Nitrogen Removal Membrane /Ammonia Removal Membrane(MBC-2040)

The treatment of ammonia nitrogen wastewater has always been a thorny issue in the field of environmental protection. For this reason, after years of research, SCI-NANO has developed a deamination membrane module based on PTFE hollow fiber membranes. This component takes advantage of the strong hydrophobicity, air permeability and water impermeability of the PTFE membrane to carry out the deamination stripping and absorption processes at the same time. In actual operation, by adjusting the pH value of the wastewater to alkaline, the ammonia nitrogen ions in the wastewater will be converted into ammonia water. Then, a certain ammonia partial pressure difference is created on both sides of the membrane, so that the ammonia gas passes through the membrane wall from the wastewater side with a larger partial pressure difference to the absorption liquid side with a lower ammonia partial pressure. This can effectively reduce the ammonia nitrogen content in wastewater. In addition, the PTFE deamination membrane has good sealing performance and does not require additional air blowing, thus avoiding secondary pollution. Moreover, the process is carried out under low pressure and has significant energy saving effect. Because the PTFE material itself has the characteristics of strong hydrophobicity, high strength, corrosion resistance and anti-pollution, the PTFE deamination membrane module also has the advantages of long life, strong anti-pollution ability, and can be cleaned and regenerated.


· The high density of the membrane allows for a high removal rate of ammonia nitrogen.

· The system operates at nearly normal pressure, resulting in over 80% energy savings, low energy consumption, and reduced operating costs.

· The membrane material is made of PTFE, which provides resistance to corrosion, acids, alkalis, and high temperatures, and has high hydrophobicity. It is insoluble and does not melt.

· The membrane has uniform and narrow pores, which help prevent issues like polarization and scaling.

· The membrane wire is woven into an array, which enhances its ability to withstand the impact of the fluid, preventing breakage and ensuring a long, stable service life.
