Abstract: Arrangements and methods for contacting a gas and a liquid involve transferring a gas from one side of a pleated fluid treatment medium, through the fluid treatment medium, and into a liquid on the other side of the pleated fluid treatment medium to form a solution of the gas in the liquid.

Abstract: A method for removing iron-containing contaminants from condensate from a power generating plant includes passing the condensate through a plurality of pleated filter elements contained within a housing, including direct the condensate through a pleated hydrophilic film comprising ultra-high molecular weight polyethylene. The invention is capable of removing fine particulate matter and provides long filtration cycles between backwashing.

Abstract: A shear separation system or method uses shear lift forces and permeate drag forces to separate substances having a size less than a predetermined separation size from substances having a size greater than the separation size. The balance of the drag forces and lift forces affects a predetermined separation size in that the balance of forces reads the transmembrane passage of substances larger than the separation size yet allows substances smaller than the separation size to pass through the permeable membrane. The shear separation device, method and system can be employed to separate or concentrate from a process fluid substances larger or smaller than the predetermined separation size.

Abstract: A filter includes a cylindrical filter element (10) having a longitudinal axis, first and second end surfaces, and a plurality of longitudinal pleats (11). Each of the pleats has a pair of legs with first and second surfaces. The pleats are in a laid-over state in which the first surface of each leg is in intimate contact with the first surface of an adjoining leg and the second surface of each leg is in intimate contact with the second surface of an adjoining leg over substantially the entire height of each leg and over a continuous region extending for at least approximately 50% of the axial length of the filter element. An impervious end cap (40) is connected to the first end surface of the filter element.
