A method for filtering a dairy product is used in a filter system that includes at least one pump loop having a pump and a filter, with the pump being arranged to feed a feed product to the filter for filtering the feed product and outputting a permeate product and a retentate product. The method includes supplying the feed product to the pump at a feed pressure, during a first operational mode in which the feed pressure is below a first predefined threshold, controlling the pump to operate at a first power that is within a first percentage range of a maximum rated power of the pump, and during a second operational mode in which the feed pressure is above the first predefined threshold, controlling the pump to operate within a second percentage range of the maximum rated power which is higher than the first percentage range.

A method and system is provided for treating waste generated from manufacturing operations including at least one of Printed Circuit Boards Fabrication (PCB FAB), General Metal Finishing (GMF), semiconductors manufacturing, chemical milling, and Physical Vapour Deposition (PVD). The method and system are used to create zero liquid discharge recycling.

Provided are electrodialysis systems comprising a plurality of electrodialysis devices, wherein each electrodialysis device of the plurality of electrodialysis devices has a product inlet stream, a product outlet stream, a brine inlet stream, and a brine outlet stream. The product inlet stream for a first electrodialysis device comprises the brine outlet stream of a second electrodialysis device. Further, a first portion of a feed stream is the brine inlet stream for the first electrodialysis device and a second portion of the feed stream is the brine inlet stream for the second electrodialysis device or a third electrodialysis device.

The invention relates to a system and method of use for concentrating a solution that is eluted from an ion exchange process (elution solution) during an ion exchange regeneration using the osmotic pressure of the salt saturator. This method recovers solvent from the elution solution that could be used in a future ion exchange regeneration process. The concentration of the elution solution may include the precipitation and removal of solids from the elution solution.

This specification describes membrane based filtration and softening systems and methods. A system has a microfiltration or ultrafiltration (MF/UF) membrane unit upstream of a nanofiltration or reverse osmosis (NF/RO) membrane unit, optionally with no intermediate tank. In some cases, the system and method may be used with feed water provided at municipal line pressure to the membranes. NF/RO permeate is collected in a tank and then pumped to a header. Treated water may be drawn from the header for use or recycled to the system, for example to backwash or flush one or both of the membrane units. In a combined process, NF/RO permeate flushes the feed side of the NF/RO unit and then backwashes the MF/UF unit. In another process, the MF/UF unit and NF/RO unit are filled with NF/RO permeate before being placed in a standby mode.

The present disclosure is directed to an electrodialytic stack with a concentrate stream that moves through a concentrate flow path bounded by a central ion exchange membrane and a first outer ion exchange membrane. A dilute stream moves through a dilute flow path bounded by the central ion exchange membrane and a second outer ion exchange membrane. A redox shuttle loop is separated from the concentrate and dilute streams by the first and second outer ion exchange membranes, respectively. The outer ion exchange membranes are a different type than the central ion exchange membrane. Electrodes are operable to apply a voltage across the stack. At least one collection of ion exchange materials is located in at least one of the flow paths. The ion exchange materials migrate ions between the central ion exchange membrane and at least one of the outer ion exchange membranes.

A system, method and device are disclosed for bio-processing a feed stream and providing a constant output by operating a continuous single-pass tangential-flow process. The single-pass process provides high conversion concentration while operating at relatively low feed flow rates, and the process can also be used to provide constant output diafiltration.

A technology that provides various modular biomimetic microfluidic modules emulating varieties of microvasculature in body. These microfluidic-base capillaries and lymphatic Technology modules are constructed as multilayered-microfluidic microchannels of various shapes, and aspect ratios using diverse biocompatible microfluidic polymers. Then, various semipermeable membranes are sandwiched in between these multilayered microfluidic microchannels. These membranes have different chemical, physical characteristics and MWCO values. Consequently, this design will produce much smaller dimension channels similar to human vasculature to achieve biomimetic properties like of human organs and tissues. By interchanging microfluidic-layers or the membranes various diverse modules are designed that act as building blocks for constructing various medical devices, various forms of dialysis devices including albumin and lipid dialysis, water purification, bioreactors, bio-artificial organ support systems. Connecting various modules in diverse combinations, permutations, in parallel and/or in series to ultimately design many unrelated medical devices such as dialysis, bioreactors and organ support devices.
