摘要： An immersed membrane system or process may use measured or calculated process information to optimize one or more process operating parameters to improve performance or reduce operating costs. An on-line process control system or method may use the resistance in series method in operating an immersed membrane water treatment system. A process control system or process may consider resistance values and adjust operational parameters such as membrane aeration frequency factor, membrane aeration flow, permeate flux, permeation duration, backwash flow and duration, relaxation duration or maintenance or recovery chemical cleaning frequencies in order to reduce the operational costs related to membrane fouling removal.

摘要： A fluidic system having a first volume, a second volume and a membrane geometrically separating the two volumes, which has an open-pore microstructure for the passage of a first medium and a second medium. There is a contact angle (Θ) between the interface of the media and the pore surface. A first electrical field in the region of the membrane and a first electromagnetic radiation and a first heating of the membrane define a first state (Z1), in which the membrane is not wetted or is less wetted by the first medium and is more heavily wetted by the second medium such that a first contact angle Θ1>90° is formed between the pore surface and the interface. The first medium and the second medium and the pore surface have a surface energy of which at least one surface energy can be reversibly changed in such a way that a second contact angle Θ2

摘要： A fluid storage and dispensing assembly includes a fluid chamber having at least one side wall extending between an upper end and a closed lower end thereby defining a reservoir. A lid connectable proximate the chamber upper end has a first surface and an opposite second surface and defines a fluid inlet connecting the first and second surfaces. The fluid inlet defines an axis and includes a first fluid sealing member. A fluid filtration unit having a first end configured for removable fluid tight attachment to the lid at the second surface and a second end is provided with a filtration channel defined therebetween. The second end defines a filter outlet, and a unit of filter media is positioned between the first and second ends. The filtration outlet is in fluid communication with the fluid inlet when the first end is attached to the lid unit, wherein the first sealing member is configured for releasable attachment in a fluid tight seal with a head of a pressurized fluid source when engaged such that the pressure from the fluid source forces fluid from the source through the filter media and from the filtration outlet into the reservoir.

摘要： A flow filtration system (1) for concentration of components contained in a fluid sample comprises a fluid channel (2) being formed by two conduits (4, 5) allowing a bidirectional flow of the fluid sample through the fluid channel (2), a tangential flow filtration module (3) and at least two pairs (8, 9) of piston pumps (6) each having two piston pumps (6), wherein the piston pumps (6) having a piston swept volume forming a reservoir being able to contain the fluid for volumes of up to 100 ml. The tangential flow filtration module (3) is located in the fluid channel (2) so that a fluid flowing through the channel (2) passes through the filtration module (3). At each end (10, 11) of the channel (2) one piston pump (6) of each pair (8, 9) of piston pumps (6) is located in such a manner that the piston pumps are fluidically connected in parallel. The system (1) is arranged and adapted such that during the concentration process at least for a predetermined period of time only one of the pairs (8, 9) of piston pumps (6) is used to drive the fluid through the tangential flow filtration module (3).

摘要： A water filter cartridge is reduced in fluctuation in filtration flow rate or in filtration performance due to activated carbon, and can exhibit stable performance even at the time of large scale production; and a water purifier is equipped with the water filter cartridge. A water filter cartridge having particulate activated carbon filled in a case for accommodating a filtering material in which the ratio of the total mass of particulate activated carbon having a particle size of 0.3 to 4.0 mm relative to the total mass of activated carbon is 97% by mass or more, and, in a particle size distribution which represents the relationship of the mass ratio of activated carbon relative to the particle size of activated carbon, a peak at which the mass ratio is 31% by mass or more does not appear in a particle size range of from 0.3 to 4.0 mm.
