Abstract: A filtration system using lightweight fibrous media (LFM) that are pre-compressed either 1) manually; or 2) in-situ using hydraulic flow; and where the LFM are forced to separate and relax for cleaning either: 1) manually, 2) in-situ in their filter housing, or 3) in an auto-clean system using separate devices in order to enact a particularly aggressive cleaning process. A plurality of lightweight fibrous media balls are pre-compressed and used to form a single mass that can filter water as the media are compressed by pre-compression before installation, or by water flow pushing on a pre-compression plate during filtration thereby forming a single mass providing multitudes of tortuous paths through which water can flow and the media can capture small particulate matter.

Abstract: Impure steam is partially cooled on a first side of an energy transfer dee, forming a condensate substantially free of CO.sub.2 and other non-condensible gases. The condensate is separated from the impure steam and accumulated in a separator/accumulator. The condensate stream is conveyed through a control valve back to a second side of the energy transfer device for reheating to steam substantially free of CO.sub.2 and other non-condensible gases.
