Membrane method for removing waterCO2 and O2 Technology Description

working principle:

By utilizing the hydrophobic properties of polypropylene film, water cannot penetrate the membrane wall, while gas can pass through the membrane wall and change its solubility in water. Changing the environmental gas pressure or the composition of gases in a closed system can purposefully alter the gas content in water or a specific gas.

Membrane method for removing waterThe method for CO2 and O2 is to let water flow inside the hollow fiber membrane tube and change the pressure of the gas outside the tube, such as by negative pressure or pressurization (adding pure N2, etc.), to reduce the solubility of oxygen and carbon dioxide in water and achieve the removal effect. This is a new application of membrane separation technology and a novel gas/liquid film separation process.

By vacuuming, vacuuming+Methods such as N2 can achieve an O2 removal rate of over 90% in water, while methods such as vacuum pumping and compressed air can achieve an CO2 removal rate of over 85% in water

Water quality requirements for membrane inlet:

Raw liquid coarse filtration:<50 μ m Turbidity:<10NTU pH: 1-14 Temperature: 1-45 ℃

Recommended inlet working pressure:0.2 Mpa higher inlet pressure:<0.4 Mpa (adjusted according to vacuum negative pressure)

The original solution cannot contain moistureThe components of PP film, such as alcohol, etc.
