General Information

MCOL-12X28 is manufactured as an equivalent, replacement, alternative, retrofit and analogue to replace 3M Liqui-Cel EXF-10x28 X40 membrane contactor.
TaCel O2 Liqui series membrane contactor MCOL-12X28 has unique design of hollow fiber braiding, baffle and central pipe water distribution structure, and is mostly used for deoxygenation of boiler feed up water, replacing thermal contactor.
The working principle of 3M Liqui-Cel EXF-10x28 X40 equivalent membrane contactor:
MCOL-12X28 uses microporous hollow fiber membrane to remove oxygen from water. In a typical operation, water flows outside the hollow fiber membranes, while 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 in the water.

Features

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

Extra larger membrane area for higher capacity and removal rate
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.
Economical equivalent membrane contactor for direct replacement of 3M Liqui-Cel EXF-10×28 X40

Notice:
1. These Liqui-Cel EXF-10x28 X40 membrane contactor equivalents 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.
