Challenges and Issues of Using Phosphoric Acid as an Absorption Liquid in Membrane-Based Ammonia Removal

While phosphoric acid can theoretically be used in membrane-based ammonia removal, its rapid pH fluctuation, limited absorption capacity, unstable reaction products, membrane fouling risks, and poor economic viability make it less suitable for practical applications. Currently, sulfuric acid (H₂SO₄), nitric acid (HNO₃), and hydrochloric acid (HCl) are more commonly used due to their higher efficiency and stability. When selecting an absorption liquid, it is essential to consider chemical stability, ammonia removal performance, and long-term operational costs to optimize the overall process.to resist.

Experimental Report III on PTFE Membrane Deamination Test at High Temperature

When the amount of alkali added to the raw water increases, the ammonium root in the raw water will fully react with the hydroxide to generate ammonia, which increases the air permeability of the deammoniated membrane, resulting in a decrease in the ammonia nitrogen produced in the water. When the influent flow rate decreases, the air permeability per unit area of the deamination membrane increases, and the deamination effect is enhanced, which causes the decrease of ammonia nitrogen in water production.

Experimental Report on High Temperature PTFE Membrane Deamination Test II

Under the conditions of raw water temperature 70 ℃ and acid absorption solution pH = 1, when the alkali addition amount of wastewater is about 1.5g/L(pH = 9.03) and the raw water flow rate is 13.2L/h, the ammonia nitrogen content of water produced by primary membrane deamination after stable operation is 9.5mg/L, which meets the ammonia nitrogen requirement of drainage. The raw water is fed into 20L, and the sulfuric acid absorption solution is reduced by about 0.2L. In order to ensure the stable discharge of effluent up to standard, the alkali addition amount can be controlled to 1.5g/L, the raw water flow rate to 12.0L/h, and the ammonia nitrogen content of the water produced by the primary membrane deamination after stable operation is 7.2mg/L.

What is the difference between ammonia removal membrane and reverse osmosis membrane?

A reverse osmosis membrane is a semi-permeable membrane that allows water molecules to pass through it, but it blocks most of the dissolved salts, organics, bacteria and pyrogens. On the other hand, membrane contactors can only effectively remove gases such as oxygen, carbon dioxide, and ammonia in water, but cannot eliminate ions, bacteria, organic matter, or suspended solids.
