Abstract
The present disclosure provides systems and methods that can treat feeds with elevated organic levels, e.g., feeds with ≥300 Pascals (Pa) organic osmotic pressure, with one or more enhanced filter membrane modules, which may be referred to herein as membrane modules or simply modules. Preferably, a filter membrane module consistent with the present disclosure include one or more plate and frame modules, one or more spiral format modules, or a combination of plate a frame and spiral format modules. The systems and methods provided herein can provide reliable performance when used to treat feeds with elevated organic levels.
Claims33
A method for treatment of a feed stream to provide at least 30% of the feed stream as permeate, the method comprising:
- determining an organic osmotic pressure for a feed stream or a retentate stream, the organic osmotic pressure being at least 300 Pascal (Pa);
- selecting at least one filter membrane based on the determined organic osmotic pressure, the at least one selected filter membrane having a feed channel height of at least 0.5 mm;
- and
- selecting an open channel average velocity for the at least one selected filter membrane of at least 0.05 meters per second.
A filtration system for treatment of a feed stream, the filtration system comprising:
- at least one filter membrane, the at least one filter membrane having a feed channel height of at least 0.5 millimeters and an open channel average velocity of at least 0.2 meters per second, a feed inlet to couple to a feed stream, a permeate outlet to couple to a permeate stream, and a retentate outlet to couple to a retentate stream;
- a pump fluidly coupled to the inlet of the at least one filter membrane to displace feed from the feed stream into a feed channel of the at least one filter membrane;
- and
- wherein the feed stream or the retentate stream has an organic osmotic pressure of at least 300 Pascal (Pa), and wherein at least 30% of the feed stream is recovered and output as permeate to the permeate stream by the at least one filter membrane.
