摘要： Systems and methods for rapid flushing of a membrane-based fluid filtration system are disclosed herein. During flushing, a membrane of the system can be decoupled from other portions of the system and brine can be flushed from the membrane separate from the other portions of the system. In some embodiments, the membrane can be connected to a pump to form a flushing loop that is separate from the flushing loops of the main system to flow the flushing fluid therethrough. The flushing fluid through the membrane can be optimized and set based on a flow rate of the membrane to prevent damaging the membrane while minimizing flush time of the membrane relative to the flush time of the system.

摘要： A combination of a single-station reverse-osmosis (RO) device comprising a hemodialysis device (HD device) is characterized in that a connection line is provided with a buffer chamber for permeate which serves on the one hand a faster permeate supply into the HD device and on the other hand a generation of a negative transmembrane pressure, and that upon request by the HD device the permeate flows either via the water inlet valve into the HD device or via a flushing valve of the HD device to an outlet.

摘要： A water purification apparatus (300) capable of being cleaned at a point of care, and methods for cleaning the water purification apparatus (300) at the point of care. The water purification apparatus (300) and the methods provide an efficient use of a heater (302) for heat disinfection the water purification apparatus (300), e.g. by recirculating heated fluid to further heat the fluid. Several different cleaning programs are provided that may be utilized for cleaning different parts of the water purification apparatus (300).
