The present invention discloses a rectangular shaped filter and coalescer elements and a vessel that houses a plurality of such rectangular shaped elements. Greater filtration or separation efficiency is provided due to increased number and alignment of rectangular shaped filter elements in the vessel. The rectangular shaped filter elements are also easy to replace.

A cassette filter for cleaning a fluid includes: a frame; and a plurality of filter elements having a filter medium provided with a folding. The plurality of filter elements are accommodated in a frame such that at least two adjoining filter elements of the plurality of filter elements are arranged at an acute angle to one another and form a V-shaped arrangement. Each of the plurality of filter elements has folded edges which are formed by fold peaks and fold valleys and extend perpendicularly to legs of the acute angle. Each filter element of the plurality of filter elements is provided with foldings such that a height of the respective filter element is smaller at all edge regions than a height in a central region of the respective filter element, and smaller folding surfaces than the central region result at the edge regions.

A regenerative filter that includes a filter housing having inlet and outlet zones; a fluid path provided between the inlet and outlet zones; a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path; and a tube sheet that is supported across the filter housing, that is disposed just before the outlet zone and that provides the support for the plurality of filter elements. The plurality of filter elements are disposed in an array and includes bridging members or elements that connect between adjacent filter elements, and that forms with the filter elements, a closed interstitial space between adjacent filter elements for liquid flow; a nanoscale barrier on interior surfaces, including that of the regenerative media itself, providing a mechanism to disrupt the cell wall of microscopic viruses and organisms.

A filtration module is provided, the module including at least one filtration packet containing filtration media or one or more membranes, such as a stack of membranes, the at least one filtration packet having one or more fluid ports, the one or more fluid ports being surrounded by a primary seal and a secondary seal spaced from the primary seal. The secondary seals are designed to maintain sterility of the assembly during shipping, handling and/or installation. A removable film may cover one or more fluid ports to maintain sterility prior to use.

There are provided a rainwater filtering device and a monitoring system therefor. The rainwater filtering device includes: a filtering unit including a strainer therein; a first overflow preventing unit supported by a compression rod and installed above the filtering unit; a pre-treating unit installed in front of an inlet of the filtering unit in order to pre-treat rainwater introduced into the filtering unit; and a second overflow preventing unit supported by a compression rod and installed above the pre-treating unit.

A regenerative filter that includes a filter housing having inlet and outlet zones; a fluid path provided between the inlet and outlet zones; a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path; and a tube sheet that is supported across the filter housing, that is disposed just before the outlet zone and that provides the support for the plurality of filter elements. The plurality of filter elements are disposed in an an.sup.-ay and includes bridging members or elements that connect between adjacent filter elements, and that forms with the filter elements, a closed interstitial space between adjacent filter elements for liquid flow; a nanoscale barrier on interior surfaces, including that of the regenerative media itself, providing a mechanism to disrupt the cell wall of microscopic viruses and organisms.

In accordance with an aspect of the present disclosure, an apparatus includes a tubular filter and a motor coupled to the tubular filter. The tubular filter includes a plurality of apertures. The motor rotates the tubular filter about an axis while a differential pressure is applied to an interior space of the tubular filter relative to exterior to the tubular filter. A force is applied, related to the rotation of the tubular filter, to particulate matter agglomerated to an exterior surface of the tubular filter such that the particulate matter is removed from the exterior surface.

Disclosed is a dynamic separation and filtration system for dewatering and dehydrating of slurries and sludges. The system includes a compression filter press cylinder in which hydraulic pressure within a sealed liner is used to press and separate moisture from a sludge. A self-contained closed sealed liner pressurizing component is connected thereto, for supplying pressurized hydraulic fluid to the sealed liner, and a compressed air and vacuum and backflushing cylinder component is connected thereto for voiding the press cylinder of a resulting cake. A sludge transfer and metering component supplies metered quantities of sludge to the press cylinder. A dynamic filtration clarifier and thickener initially separates solids from a slurry and thickens the slurry into sludge that is supplied to the metering component.

An adaptor device for retrofitting in a pool filter housing is disclosed, where the pool filter housing has a conventional cylindrical concentric filter. The adaptor device allows the pool filter to be retrofitted with a plurality of filter elements, thereby improving its filtering efficiency.
