网页2016/10/25 · With experience extending as far back as 1965, Alfa Laval's specialists can answer the question in detail. Membrane filtration process is a physical separation method characterized by the ability to separate molecules of different sizes and characteristics. Its driving force is the difference in pressure between the two sides of a special membrane.
网页2020/01/10 · In addition to the test cell, the below equipment will be required in an MD lab set up: Low pressure pump× 2 (<100 psi) Low pressure tubing. Flow meters. Pressure gauges (pressure spikes above the liquid entry pressure could wet the membrane and let the water to permeate through) Feed tank and coolant/permeate tank. Scales.
网页If the membrane does not have a substrate, it is bio-directional and either side can be used as the inlet. If it has a substrate, the substrate layer will be more coarse and ridged than the membrane side. The membrane side would be the inlet and the coarse substrate side the outlet. The solvent should enter the inlet side of the membrane first.
