Liquicell 3M Equivalent
- Product No.:MCO2-5X20LM
Equivalent, equivalence, replacement, alternative, analog, retrofit, analogue, derivative, substitution: Liquicell 3M membrane contactor
General Information
MCO2-5X20LM is manufactured as an equivalent, replacement, alternative, retrofit, analogue and derivative to replace Liquicell 3M membrane contactor.The working principle of Liquicell 3M equivalent membrane contactor:
Liquicell 3M equivalent membrane contactors use microporous hollow fiber membrane to remove oxygen from water. In a typical operation, water flows outside the membrane hollow fibers, while inside of the hollow fibers are vacuum pumped or gas purged, or both are combined.
The hydrophobically treated hollow fiber membranes have many micro pores on the surface, which allow gas molecules to pass through, but can prevent water molecules from penetrating. Under the negative pressure of vacuum or gas purging, the dissolved gas in the water outside the hollow fiber membrane moves continuously to the inside of the hollow fiber membrane through the micro pores, and is taken away by the vacuum or purging gas, so as to achieve the purpose of removing dissolved oxygen, carbon dioxide and other gases in water or other liquids. Liquicell 3M equivalent membrane contactors can also be used for membrane extraction, deamination and denitrification etc.
Features
- Superphobic hollow fiber
- Compact design for normal base construction with installation
- Can be installed directly on ground, no need of high position installation.
- Works under normal temperature, no need of hot steam for deoxygenation.
- Energy consumption comes from vacuum pump and sweep N2
- Modular design, can be extended very easily.
Advantages
- Superphobic hollow fiber for high performance
- Energy saving by low energy consumption
- High removal efficiency for dissolve oxygen, keep stable at 7 ppb of outlet water.
- Small footprint to save CAPEX
- Easy to install, operate and maintain for lower OPEX.
Applications
- Food & beverage
- Pharmaceuticals
- Microelectronics & semiconductors
- Gas separation
- Inkjet printing
- Hydrometallurgy
- Coating

1. These Liquicell 3M membrane contactors are only suitable for deoxidization of clean water, COD < 50 ppm, SS < 5 ppm.
2. Even if COD in water is less than 50 ppm, the surface tension may still be less than 65 mN/m, resulting in membrane infiltration. Therefore, the detection of surface tension is necessary before use.
3. The water should not contain oxidizing substances, such as hypochlorite, hydrogen peroxide, etc. ORP < 100 is required, otherwise the service life of the membrane conctactor will be affected.
4. When used for a long time, the organic and mineral substances in water will cause membrane fouling, which will affect the removal and hydrophobic properties of the membrane. It should be cleaned regularly and restored.
