A fluid filter assembly that is defined by a head portion, a base portion, and a filter tube housing that is captured therebetween. Each head portion includes more than one fluid inlet and more than one fluid outlet that are oriented relative to the respective head portion such that a plurality of fluid filter assemblies can be fluidly connected to one another to provide a desired degree of filtration of the fluid passed therethrough and such that the fluid filter assemblies can be oriented in a plurality of orientations relative to one another to provide a desired configuration of the fluid filter assembly.

The invention relates to a particle filter device (1) comprising: a fluid inlet (20), a fluid outlet (21), a first fluid flow circuit (31) comprising a first filter zone (2) having a first filter surface (S.sub.1), a second fluid flow circuit (32) comprising a second filter zone (3) having a second filter surface (S.sub.2) and a constriction (4) having a constant hydraulic resistance so that, in operation, a first portion of the fluid flows through the first flow circuit (31) by passing through the first filter zone (2) and a second portion of the fluid flows through the second flow circuit (32) by passing through the second filter zone (3) and the constriction (4), and the first filter zone (2) reaches a predetermined clogging condition before the second filter zone (3).

Methods of filtering a liquid feed are disclosed. In one version, the method comprises passing a liquid feed through a single pass tangential flow filtration (SPTFF) system and recovering the retentate and permeate from the system in separate containers without recirculation through the SPTFF system. In another version, the method of filtering a liquid feed, comprises passing a liquid feed through a tangential flow filtration (TFF) system, recovering permeate and a portion of the retentate from the system in separate containers without recirculation through the TFF system, and recirculating the remainder of the retentate through the TFF system at least once. The methods can be performed using an SPTFF or a TFF system that comprises manifold segments to serialize the flow path of the feed and retentate without requiring diverter plates.

A system for filtering particles from a fluid includes a strainer. The strainer includes a housing having an inlet, a first outlet, a second outlet. A filter element is positioned in an internal volume of the housing. The filter element defines a bore formed axially-therethrough and openings that are substantially transverse to the bore. A first portion of the fluid that enters the housing through the inlet flows through the openings in the filter element and exits the housing through the first outlet, and a second portion of the fluid that the housing through the inlet bypasses the openings and exits the housing through the second outlet.

A filter assembly including an RFID tag, for use in monitoring fluid processing, as well as a system and a method for monitoring fluid processing, and a filter for use in the filter assembly, are disclosed.

Flow sensors are provided that can provide both leak detection and flow monitoring. The flow monitoring enables a determination whether there are blockages or leaks in a fluid system during normal operation of the system. The leak detection enables detection of leaks when the system is shut off. The flow sensors can use a frusto-conical flow guide to provide a more compact flow sensor. The flow sensor components can be designed to retrofit existing filter assemblies.

A method of filtering a liquid feed is described, comprising passing a liquid feed through a single pass tangential flow filtration (SPTFF) system and recovering the retentate and permeate from the system in separate containers. A method of filtering a liquid feed is also described comprising passing a liquid feed through a tangential flow filtration (TFF) system, recovering permeate and a portion of the retentate from the system in separate containers without recirculation through the TFF system, and recirculating the remainder of the retentate through the TFF system at least once. The methods of the invention can be performed using an SPTFF or a TFF system that comprises manifold segments to serialize the flow path of the feed and retentate without requiring diverter plates.

A greywater recovery and reuse system is shown, including a body for collecting, conditioning and discharging greywater. The body has an inlet connection to a source of greywater; a filter for filtering the greywater; a tank for receiving the filtered greywater; a disinfector for disinfecting the filtered greywater; a pump for discharging the conditioned greywater from said tank to a toilet that needs flushing water; a discharge connection to a sanitary sewer system; a fresh water connection and a control system for controlling the operation of the greywater recovery and reuse system. The system includes a controller for operating the system and dealing with certain alarm and status conditions. Methods of operating the system are also comprehended.

The present disclosure relates, according to some embodiments, to methods, systems, and apparatuses for dewatering solid particles in a liquid mixture, such as those, for example, comprising receiving a liquid mixture, the liquid mixture including solid particles; suspending a filter in the liquid mixture; agglomerating, at the filter, solid particles in the liquid mixture, the agglomerating including potentiating passage of liquid in the liquid mixture through the filter and potentiating accumulation of solid particles in the liquid mixture to collect and agglomerate at the filter; and applying a shockwave to the filter, the applied shockwave operable to remove the agglomerated solid particles from the filter.
