摘要： A process is provided to produce water that will meet the specifications of the United States Pharmacopeia Inc. for Purified Water and Water for Injection, and water for dialysis as circumscribed by the American Association for Advancement of Medical Instrumentation (AAMI). The system has no storage tanks where stagnant water will be fouled by biofilm colonizing the tank surface. Water is circulated throughout the purification system and drawn as required, on demand. The water is purified and used immediately or recycled and repurified to ensure quality. Sanitation of the purification system, maintaining microbiological purity and cleaning is done by controlling the pH so that it is normally acidic by maintaining a high carbon dioxide concentration in solution, the carbon dioxide being allowed to pass into the permeate from a reverse osmosis membrane assembly (72,74) used to purify the water.

摘要： A portable liquid-filtration device includes an inlet port, a filtering portion including a filtering medium and fluidly coupled to the inlet port, a filtered-liquid output port fluidly coupled to the filtering portion, a flush port fluidly coupled to the filtering portion, and a manually activated pump assembly fluidly coupled to the inlet port, filtering portion, output port and flush port. The pump assembly is configured, when activated, to create a negative fluid pressure at the inlet port and a positive fluid pressure at the output port and the flush port. As a consequence of activation of the pump assembly, the filtering portion receives unfiltered liquid from the inlet port, the output port receives from the filtering portion only liquid traversing the filtering medium in a first direction, and the flush port receives from the filtering portion liquid traversing the filtering medium in a second direction different from the first direction.

摘要： The present invention relates to a seawater desalination device, a seawater desalination method and a potion cleaning method. The seawater desalination device comprises a seawater introducing and filtering device and a seawater reverse osmosis filtering device. A first control valve is arranged between the filtering device after the introduction of seawater and the seawater reverse osmosis filtering device; and a second control valve is arranged at the end of pipeline of the seawater reverse osmosis filtering device. The seawater desalination device further comprises a control circuit. The seawater introducing and filtering device is consisted of a seawater inlet valve, a seawater pump and a filter which are communicated in turn via pipeline; the seawater reverse osmosis filtering device is consisted of the first control valve, a high-pressure pump, a reverse osmosis membrane group, a pressure regulating valve, the second control valve and a clean water tank which are communicated in turn via pipeline. By adopting the above structure, the seawater desalination device, the seawater desalination method and the potion cleaning method are controlled by a variety of combination of manual control and electronic control. And, seawater desalination stop cleaning step and potion cleaning step are reduced, the structure is simplified, and the efficiency is improved.

摘要： The present invention relates to a method for circulating a mixture of at least two fluids through the second portion (34) of a duct after said mixture has circulated through the first portion (32) of said duct. To this end, a partial flow of the fluids is diverted at a given point (43) in the second portion (34) of the duct, and said partial flow is further directed back into the second portion (34) of the duct at another point. This invention also relates to an embodiment of this method for preventing the stoppage of modules in a cross-flow filtration unit, as well as to devices for realising said method.
