A disposable filtration device includes a plurality of disposable filter capsules connected with each other by lines, which are carried by a rigid holder. At least the holder and the lines between the filter capsules preferably are formed of a sterilizable material, so that the filtration device can be sterilized in the pre-mounted, i.e. ready-to-connect condition, and can be packed and transported without a risk of damage.

Examples disclosed herein relate to methods and systems for controllably removing one or more solutes from a solution. Examples disclosed herein relate to methods and systems for removing water from alcoholic beverages.

A greywater treatment system includes a first modular greywater processing apparatus having a raw greywater inlet, a mechanical (MTF) filter connected to the raw greywater inlet, a first ultrafine (UF) filter connected in series downstream of the mechanical filter. The UF filter includes a UF filter inlet, a filtrate outlet, and a cross-flow outlet. The filtrate outlet is connected to a processed water outlet. A modular base supports the mechanical filter and the UF filter.

A cross flow filtration unit, which provides a planar, rigid filter plate for filtration of liquid media. The plate has a planar membrane, which is fluid tight bonded at its edges to the surface of a partly hollow supporting plate having exit openings, internal flow channels, and flow areas for a first liquid medium. The membrane is in fluid contact with said the liquid medium at its internal surface and being in fluid contact with a second liquid medium at its external surface.

A blood treatment system and method controlling same are provided. The system comprises a blood pump for urging blood from an arterial or venous interface through a blood flow path; a dialyser in fluid communication with said blood flow path for ultrafiltering the blood to remove fluid therefrom; a fluid removal pump in fluid communication with said dialyser for urging ultrafiltered fluid away from said dialyser; a controller in signal communication with said blood pump; and a reversing valve for selectively reversing direction of blood flow in at least a portion of the blood flow path under signal control of said controller. The blood pump is selectively activatable under signal control of the controller.

The disclosure provides a filtration system for a cell culture apparatus and a method of cell culture. The filtration system comprises a bioreactor vessel and two or more alternating tangential flow (ATF) filters connected in parallel. A failure in either filter is detected by an in-line sensor, and an automated response system functions to sequester the malfunctioning filter by stopping the flow of liquid media through the filter. Media flow through the remaining operable filters can be increased so that the rate of perfusion through the bioreactor remains relatively unchanged. Such a system may prevent issues that arise from ATF filter failures in conventional perfusion bioreactors, thereby improving the long-term viability of cell cultures.

Examples relate to systems and methods for concentrating acetic acid solutions using multi-tier ultrahigh pressure (“UHP”) reverse osmosis. Along with an acetic acid product having a concentration of at least 25 weight percent (wt %), the systems and methods disclosed herein simultaneously provide water with an acetic acid concentration of 2 wt % or less in at little as three tiers.

A modular header for a filtration module assembly is provided. The modular header includes a main body, a first liquid passageway and a second liquid passageway extending through the main body, and a gas passageway extending through the main body. The gas passageway has a first open end formed at a first side surface of the main body and an opposing second open end formed at a second side surface of the main body. An auxiliary adapter is secured to the main body at at least one of the first and second open ends of the gas passageway.

Forward osmosis membrane vessels, and particularly stackable forward osmosis membrane vessels, are provided as well as systems and methods thereof. The forward osmosis membrane vessel has a body, a strong draw solution chamber, a first and a second semipermeable membrane, and a brine chamber. The first and second semipermeable membranes each are disposed within the cavity of the body. The first and second semipermeable membranes are configured to produce diluted draw solution streams and brine streams. The brine chamber is disposed at least partially between the first semipermeable membrane and the second semipermeable membrane. The forward osmosis membrane vessel may be configured such that in a stacked configuration the brine chamber and the strong draw solution chamber of the forward osmosis membrane vessel aligns with a brine chamber and a strong draw solution chamber of an adjacent second forward osmosis membrane vessel.
