Abstract:

Filtration systems () utilize a pre-treatment method to cause scale formation to occur on particles () in the fluid stream () rather than on the filter surface and may also destroy microorganisms in the fluid stream. More specifically, but not limited to, a filtration device can be a filtration membrane, such as spiral wound filtration membrane (), that utilizes an open feed spacer (), such for example an embossed or printed pattern on the membrane, to create a thin feed spacer channel which replaces a conventional feed spacer mesh material. System () further utilizes a treatment device () to enable a pulsed power, magnetic, electro-magnetic, electro-static, or hydrodynamic fluid treatment scheme to condition particles in the fluid stream () such that scale forming elements precipitate () on to the particles in the fluid stream rather than on the filtration surfaces.
