This disclosure describes methods for purifying protein, and more particularly to methods for purifying protein that minimize the development of undesirable odors and flavors in the purified protein and increase protein yield.

A sterilization water discharge device is disclosed. A sterilization water discharge device includes: a tray part, which is movably disposed under a discharge member for discharging water and allows sterilization water discharged from the discharge member to be received therein and discharged; and a movement driving part for moving the tray part.

A self-contained water system that provides single point water delivery is presented. The self-contained water system purifies incoming water and restructures the purified water to deliver pure, alkaline, ionized, mineral-rich water. A first stage purification of water may be performed via pre-filtering and reverse osmosis stages that sequentially remove larger and smaller particles in the water prior to storing first stage purified water into a holding tank. A second stage purification of water is performed via a closed loop purification system that sanitizes water in the holding tank so as to kill microorganisms in the water. Restructuring of the purified water in the holding tank is performed via a water conditioner stage that remineralizes the water prior to providing for end use. Water in the holding tank can be oxygenized via a vortexing device that operates on the water in the holding tank in a closed loop fashion.

Process steps for monitoring the performance of a wastewater treatment system having a series of filtration units and optionally one or more disinfection units, controlling the operation of the filtration units, and controlling the operation of one or more maintenance operations that can be performed on the filtration units as a result of the monitoring. The wastewater treatment system can be operated without breaking pressure between the filtration units. Monitoring the performance of the wastewater treatment system can include using the water quality at various points in the system as an indicator of clogging or integrity issues within the filtration units. Sensors can be configured to measure properties of wastewater both upstream and downstream of each filtration unit, and the measured properties can be used to determine whether the filtration unit is performing adequately.

The invention proposes a biological protection membrane which is mounted, in a device for dispensing liquid from a sterile packaging bottle, across a fluid-circulation duct, in the path of the liquid extracted from the bottle and the outside air which is drawn into the bottle. The membrane (7) is made partially of a hydrophilic material and partially of a hydrophobic material. Both the hydrophobic portion (23) and the hydrophilic portion (22) are made from a polymer base, laden in the body thereof with a biocidal agent that is active in the destruction of bacteria by the ionic oxidation effect. The circulation of fluids through the membrane (7) is organised so as to promote the ionic action on the flow of outside air in the hydrophobic material, and to drive the ionically charged active agent by the liquid passing through the membrane in the hydrophilic portion thereof. A porous buffer (8), inserted in the path of the fluids on the inside of the membrane, collects the active agent extracted from the membrane by the remaining liquid not dispensed, passing through the membrane from the outside towards the inside.

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.

A water treatment subsea installation and method are disclosed, adapted for scaling prevention and treatment of raw seawater into process water suitable for use in subsea hydrocarbon production. The water treatment installation comprises a seawater inlet to a primary filtration unit wherein a filtration membrane separates a receiving chamber from a permeate chamber having an outlet for treated water. A pump is installed in fluid flow communication with the treated water outlet, a recirculation loop feeding a portion of the treated water via a subsea electro-chlorinator back to the water stream upstream or downstream of the membrane of the primary filtration unit, and a secondary filtration unit is installed in the treated water stream between the primary filtration unit and the electro-chlorinator.

A reverse osmosis system may include a water supply, a filter, and a mixing member. The water supply is connected to a first water tube and a second water tube. The first water tube is connected to the filter, and the filter is connected to a drain pipe which is connected to a wastewater tank. The wastewater generated from the filter under reverse osmosis process can be discharged into the wastewater tank. The mixing member has a water inlet end, a water outlet end, and a wastewater inlet tube, which are communicated with each other, and the water inlet end of the mixing member is connected to the second water tube. When water flows through the mixing member, the negative pressure is generated to pump wastewater in the wastewater tank through the wastewater inlet tube into the mixing member, thereby achieving the effect of water saving.

Drainage water that includes anions and cations dissolved in water and that is received from an agricultural or industrial facility is treated by applying a voltage to an anode and a cathode on opposite sides of an electrically driven separation apparatus that further includes at least one monovalent-selective ion exchange membrane between the anode and the cathode. The drainage water is passed through the electrically driven separation apparatus, wherein monovalent ions are selected from the drainage water through the monovalent-selective ion exchange membrane. The drainage water is then recirculated as treated water through the facility after the monovalent ions are removed.
