Embodiment Construction

[0052] The present invention relates to a spirally wound film roll and a film assembly including such a spirally wound film roll in a housing body, as described in further detail below and in the pending claims.

[0053] figure 1 The spiral wound membrane module according to the present invention is shown. The housing body of the spirally wound membrane module 1 includes a device for defining the housing chamber area 13. In one embodiment, the housing body includes a housing body cylinder 1a and two end caps 1b, 1c. The housing body further has a device for an inlet 8 for the second aqueous liquid, which device is in fluid communication with the central tube 7. Furthermore, the housing body has a device for an outlet 9 for the second aqueous liquid, which is in fluid communication with the housing chamber space 13. The means for the outlet of the second aqueous liquid may be in the form of a plurality of openings extending along the length of the central tube. In one embodimen...

Abstract

Spiral wound membrane rolls and modules and methods for making such membrane rolls and modules are described, along with water extraction or water filtrations systems comprising the spiral wound membrane rolls and modules and the use thereof in a forward osmosis process, an assisted forward osmosis process or a pressure retarded osmosis process.

Description

Technical field [0001] The present invention relates to a spirally wound film roll and a film module including the spirally wound film roll. Membrane rolls and membrane modules can be used in direct osmosis-driven water extraction or filtration systems, in which two water-containing streams separated by a membrane and with different osmotic pressure possibilities form a water flux on the membrane along a pressure gradient. In addition, the present invention relates to a water filtration system including a membrane roll or membrane module. Background technique [0002] There are many challenges for industrial applications that hinder forward osmosis (FO). One of the main challenges to be overcome is the proper component design that meets the requirements of film bag area, size, effectiveness, durability, convenience, and anti-fouling performance. Many of these properties are affected by the impact on each side of the film. The influence of the flow path of the two water streams....
