Principles of degassing membrane, hydrophobic membrane, and water gas separation membrane processes:
The liquid mobile phase online degassing device is usually connected between the liquid storage tank and the infusion pump, and the liquid is sucked into the vacuum chamber of the degassing device by the infusion pump from the liquid storage tank. The solution passes through the inside of the polypropylene hollow fiber membrane set in the vacuum chamber, and the polypropylene hollow fiber membrane has high permeability to residual gases in the liquid. After the solution in the membrane tube enters the vacuum chamber, bubbles are extracted from the membrane tube in a vacuum state. The liquid that has been degassed from the outlet of the degassing device is sent to the lower stage for processing through an infusion pump.
Generally speaking, the degassing efficiency is directly proportional to the area of the polypropylene hollow fiber membrane in the independent vacuum chamber and inversely proportional to the flow rate of the liquid. This device can replace the degassing tower in traditional water treatment processes
characteristic:
Compared with other traditional processes, the advantages of degassing membranes are:
Small footprint (effective contact area per unit volume is 10 times that of a degassing tower).
Low operating costs.
The gas solubility is well controlled.
Modular installation allows for easy expansion to handle larger flow rates or better control of airflow.
Low pressure loss, no need to install pressure pump, cost-effective.
1. The strength of the membrane is high. Due to the advanced “melt extrusion and stretching molding” method used in the production of polypropylene hollow fiber membranes, the polypropylene macromolecules have a regular orientation, resulting in high membrane strength. During high-intensity aeration and chemical cleaning processes, the fibers are not easily broken.

2. The chemical stability of the membrane is good. During the membrane making process of Meina polypropylene hollow fiber membrane, no additives or pore forming agents were added, resulting in good chemical stability. Strong acid, strong alkali, and chlorine containing disinfectants can be used for cleaning, and the membrane flux can be restored after cleaning.
3. Good anti pollution performance, usually used in water treatment, pure water treatment, and also commonly used in sewage and reclaimed water treatment.
