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.

What pretreatment is required for membrane distillation water?

The operation process of membrane distillation uses hydrophobic porous membrane materials as the evaporation interface. The evaporation interface must continue to maintain strong hydrophobicity. Therefore, during the operation process, the membrane material should be kept as free from contamination as possible. To maintain a well-maintained membrane distillation operation, the pretreatment of the feed is one of the very important operations. The feed conditions for membrane distillation are as follows:

What is the maximum concentration of ammonium sulfate? How to proceed?

The concentration that ammonium sulfate can achieve is related to the ammonia nitrogen content and emission requirements. We have a calculation book to calculate it. According to our experience, about 1000mg of ammonia nitrogen can roughly achieve 8-10% ammonium sulfate, about 2000mg of ammonia nitrogen can roughly achieve 15-20% of ammonium sulfate, and 3000mg can roughly achieve 20-25%;

What is membrane distillation？

The SCI-NANO membrane distillation component uses PTFE hollow fiber membrane filaments with strong hydrophobicity, high melting point, stable chemical properties and corrosion resistance. It uses the steam pressure difference on both sides of the membrane as the mass transfer driving force to efficiently remove volatile substances in aqueous solutions. It can be used Distillation desalination of water and removal of volatile substances from aqueous solutions.
