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.
Claims18
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, 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 feed inlet of the at least one filter membrane to displace feed from the feed stream into the feed channel of the at least one filter membrane;
- and
- a filter controller configured to:
- determine an organic osmotic pressure for the feed stream or a retentate stream is at least 300 Pascal (Pa);
- in response to determining the organic osmotic pressure is at least 300 Pa, cause the pump to generate an open channel average velocity for the at least one selected filter membrane of at least 0.05 meters per second.
