Zusammenfassung:A filtration system includes at least one spiral wound first filter section in fluid communication with at least one spiral wound second filter section. The first and second filter sections include: (i) a filtration membrane; (ii) a feed spacer located adjacent the filtration membrane and defining a feed flow channel; and (iii) a permeate spacer located adjacent the filtration membrane and defining a permeate flow channel. A thickness of the feed flow channel in the first filter section is different than a thickness of the feed flow channel in the second filter section, and/or an effective volume of the first filter section is different than an effective volume of the second filter section. A method of filtering a feed flow is also disclosed.
