摘要： An apparatus for processing liquids such as water or the like by means of a reverse osmosis device has a main pump which provides an entrance pressure to the reverse osmosis device in connection with a throttle. In order to avoid any losses of energy, another pump is connected to the main pump. Via a rigid shaft, a turbine is connected to the other pump which turbine receives the high pressure located in the concentrate and releases it to the other pump.

摘要： The oxygenation and removal of carbon dioxide from blood by simultaneous mass transfer through a microporous membrane is improved by pulsing the flow of oxygenating gas over the membrane. This avoids the progressive reduction in carbon dioxide transfer rate which otherwise occurs with steady gas flow and allows such transfer rate to be maintained at an acceptable level.

摘要： An ambulatory hemodialysis apparatus has a perfusion unit having multiple small internal diameter tubules secured at both tubule terminus in a pair of plastic header plates. The plate pair are secured in a rigid exchanger shell having an inlet and outlet dialysate conduit, forming a perfusion unit typically having 25 ml. blood and 25 ml. dialysate contained volumes, as scaled in size for an adult patient. Cellophane or deacetylated cellulose triacetate tubules, of 0.2 mm to 2.0 mm internal diameter by 8 cm length, provide the blood residence volume for dialysis. A rigid exchanger for shell, typically 8.5 cm long X 6 cm wide X 1 cm thick, provides the dialysate volume. A femoral arteriovenous cannulae positioned on the thigh provides an exteriorized artery cannula to the blood inlet conduit of the portable perfusion unit, and the blood outlet conduit of the unit is connected to the venous cannula. The required dialysate is circulated through two perfusion conduit connections to a portable patient-worn dialysate reservoir, and the dialysate is pumped by patient generated pulses, such as arterial and breathing pulses, utilizing a check-valve controlled diaphragm pumping means. Dialysed excreta is manually periodically voided from the dialysate reservoir by the patient, on periodic signal by a patient powered pulse counter. An orifice disposed in the blood outlet conduit of the perfusion unit can symmetrically increase blood pressure and accelerate water removal from the patient''s blood.

摘要： A drainless reverse osmosis (RO) water purification system provides relatively pure water for on-demand dispensing, while recycling brine to a domestic hot water system. The drainless purification system includes a pre-filter catalyst cartridge for removing chlorine-based contaminants from a tap water supply upstream from an RO membrane. The catalyst is regularly refreshed by a high through-flow of water to a conventional cold water dispense faucet, thereby significantly prolonging the service life of the RO membrane. The RO membrane is incorporated into a multi-cartridge unit adapted for facilitated slide-out removal and replacement as needed. A control valve recycles brine from the RO membrane to the hot water system during pure water production, and recirculates tap water through the RO membrane when a pure water reservoir is substantially filled. The multi-cartridge unit may further include an air filtration system for providing a flow of filtered air.

摘要： Embodiments of the present disclosure include a matrix of raw materials, also referred to as a poly-grain grind matrix. In some embodiments, the matrix of raw materials may form an interlocking network of varied particle grind sizes that allows the particles to nest and interlock with one another when packed into an extraction vessel, so that most, but not all of the interstitial spacing within the matrix of raw materials is closed. Additionally, the varied particle sizes may be selected by pre-determined weight ranges and size classifications so that the particle grind sizes achieve the desired consistency uniformity. This may allow the network of particles to act as its own best filtering agent during the extraction process. Moreover, the nesting and interlocking network of the particles within the matrix of raw materials may allow the particles to be effectively packed within the extraction column, thus allowing for an efficient and high quality extraction to be performed consistently each and every time.

摘要： A reverse osmosis system includes a membrane chamber having a feed line. The chamber generates a permeate stream and a brine stream from the feed line. A feed pump pressurizes the feed line. A first flow meter generates a first flow signal corresponding to a flow of fluid in the permeate stream. A booster device has a turbine in fluid communication with the brine stream and a pump in fluid communication with the feed line. A motor is coupled to the turbine device and a variable frequency drive is attached to the turbine device operating in response to the first flow signal. A second flow meter generates a second flow signal corresponding to a flow of fluid in the brine stream and a variable size nozzle operates an opening in response to the second flow meter.

摘要： A simple to operate personal water purification device using membrane type filtration with almost constant pressure exerted to the membrane filter during the operation. The water inlet is connected to the high pressure chamber via a non-return valve. The water from the chamber is injected via the piston into the already pressurized circuit which maintenance filter working pressure. A pressurized circuit is formed in the concentrate cylinder and the filtration unit. The fluid circulation within the pressurized circuit is enabled via motion of a circulation piston. The permeate outlet produces potable water while the remaining concentrate is returned to the return chamber. The circulation piston and high pressure piston are connected via piston coupling and operated, preferably, by hand activating reciprocal motion of the piston rod. The membrane type filtration can be a ultra-filtration membrane, a nano-filtration membrane or a reverse osmosis membrane.

摘要： Systems and processes for purifying and concentrating a liquid feed stream are disclosed. In the systems, the concentrated liquid output from the high pressure side of a reverse osmosis stage is used as the draw solution in the low pressure side of the reverse osmosis stage in a configuration called osmotically assisted reverse osmosis. This reduces the osmotic pressure differential across the membrane, permitting high solute concentrations to be obtained, hastening the purification of the liquid. Reduced system pressures are also obtained by arranging multiple osmotically assisted reverse osmosis stages in a cross-current arrangement. Overall system energy consumption is reduced compared to conventional thermal processes for high concentration streams.
