Embodiment 1
[0040] use figure 1 The shown double channel plate type cross-flow filtration device is equipped with a flat sheet separation membrane 3 (effective membrane area is 45cm) in the middle of the plate type membrane module 2 ), the separation membrane is a PS polysulfone ultrafiltration membrane (Alfa Laval, Denmark) with a molecular weight cut-off (MWCO) of 50kDa, and metal titanium (ruthenium-plated) electrodes close to the membrane area are respectively arranged on both sides of the ultrafiltration membrane.
[0041] The bovine serum albumin (BSA) (Mb=69kDa, purity greater than 98%) solution of fixed volume (400mL) and concentration (0.5g / L) is transported in flow path 4 by feed pump, and the transmembrane pressure of filter membrane is 0.04MPa, the cross-flow velocity of the feed liquid flowing through the membrane surface is 0.03m / s, the pH value of the feed liquid is adjusted to about 8 with 1% sodium hydroxide solution; connect the electrodes to the positive and negative el...
Embodiment 2
[0044] The same apparatus and method as in Example 1 were used.
[0045] A solution of bovine serum albumin (BSA) (Mb=69kDa, purity greater than 98%) with a fixed volume (400mL) and a concentration of 1.0g / L is delivered to flow channel 4 through a feed pump, and the transmembrane pressure of the filter membrane is 0.04MPa , the cross-flow velocity of the feed liquid flowing through the membrane surface is 0.03m / s, and the pH value of the feed liquid is adjusted to about 8; the electrodes are connected to an external DC power supply, electrode 1 is the anode, electrode 2 is the cathode, and the electric field strength is adjusted to 30V / cm; the raw material liquid cross-flows through the membrane module and returns to the feed system for recycling; the permeate through the membrane enters the flow channel 5 and is continuously discharged and collected from the permeate outlet. When the permeate accumulates to 200mL , stop the operation, record the concentration time, and test ...
Embodiment 3
[0048] use figure 1 The shown double-channel plate type cross-flow filtration device is equipped with a flat sheet filter membrane 3 (effective membrane area is 45cm) in the middle of the plate type membrane module 2 ), filter membrane selection molecular weight cut off (MWCO) is the ceramic ultrafiltration membrane (U.S. Sterlitech company) of 50kDa, and the metal titanium (ruthenium plating) electrode similar to membrane area is respectively arranged on both sides of filter membrane.
[0049] The bovine serum albumin (BSA) (Mb=69kDa, purity greater than 98%) solution of fixed volume (400mL) and concentration (0.5g / L) is transported in flow path 4 by feed pump, and the transmembrane pressure of filter membrane is 0.06MPa, the cross-flow velocity of the feed liquid flowing through the membrane surface is 0.06m / s, the pH value of the feed liquid is adjusted to about 8 with 1% sodium hydroxide solution; connect the electrodes to the positive and negative electrodes of the extern...
