Experimental Report on High Temperature PTFE Membrane Deamination Test

In this small-scale experiment, under the conditions of raw water temperature 70 ℃, alkali addition amount of wastewater about 2g/L(pH = 9.29), and acid absorption solution pH = 1.5: when the raw water flow rate is 16.8L/h, the ammonia nitrogen content of water produced by primary membrane deamination is 7.4mg/L after 10 minutes of stable operation, which meets the ammonia nitrogen requirement of drainage.

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.

Application of membrane distillation in waste acid treatment

SCI-NANO membrane distillation technology uses non-metallic plastic materials and can directly concentrate acidic solutions. It is suitable for processing mixed acids and can concentrate hydrochloric acid to 20% and phosphoric acid and sulfuric acid to 50%. The technology can also handle nitric acid and other organic acid solutions. The acid solution obtained after distillation can be further processed as needed, while the distilled water produced is of high quality and can be directly reused.

Solutions for membrane distillation technology in desulfurization wastewater

On the other hand, PTFE hollow fiber membrane evaporation technology uses low-temperature evaporation, which can effectively utilize the existing waste heat sources in the factory. While reducing the amount of high salt water, it can also reduce the scale and investment of the evaporation crystallization system on a large scale; the system process is short and has It is conducive to equipment installation and operation and is a new direction for the promotion and application of zero wastewater discharge.
