摘要： A beverage dispenser has a supply opening that supplies an aqueous liquid from a source; a recooling heat exchanger having a heat receiving portion, a recooling inlet and a recooling outlet; a reverse osmosis filter having an inlet for aqueous liquid, a permeate outlet and a concentrate outlet; and a cooling device having a cooling portion extracting heat energy from the permeate and a heat dissipation portion dissipating energy to the heat receiving portion of the recooling heat exchanger. The heat dissipation portion of the cooling device is thermally coupled with the heat receiving portion of the recooling heat exchanger. The cooling portion of the cooling device is thermally coupled with the permeate exiting the permeate outlet of the reverse osmosis filter, wherein the permeate enters the cooling portion by a cooling portion permeate inlet and exits the cooling portion by a cooling portion permeate outlet.

摘要： A water treatment system is provided. The system includes a prefiltration unit for filtering the untreated water in fluid communication with a source of untreated water. The prefiltration unit produces a prefiltered water from the untreated water. A pump in fluid communication with the prefiltration unit can selectively increase the flow rate of the prefiltered water in a first line, the first line in fluid communication with a membrane element. The membrane element produces a permeate and a retentate from the prefiltered water, the permeate being imparted with a lower concentration of solutes than the retentate. A tank in fluid communication with the membrane element and the prefiltration unit stores prefiltered water from the prefiltration unit and the permeate from the membrane element. One or more valves regulate the flow of prefiltered water and the permeate, and one or more sensors can measure characteristics of the prefiltered water.

摘要： A reverse osmosis filtration system (100, 100A, 100B, 100C), comprising: a raw water pipeline (L1); a reverse osmosis filtration unit (10, 10A, 10B, 10C) configured to filter raw water supplied by the raw water pipeline (L1); and a faucet (30, 30A, 30B, 30C) connected to the reverse osmosis filtration unit (10, 10A, 10B, 10C), wherein the faucet (30, 30A, 30B, 30C) is operable such that a water outlet (33) of the faucet (30, 30A, 30B, 30C) is selectively in communication with a product water outflow pipeline of the reverse osmosis filtration unit (10, 10A, 10B, 10C). The reverse osmosis filtration system (100, 100A, 100B, 100C) further comprises a pump unit (50, 50A, 50B, 50C) arranged between the raw water pipeline (L1) and the reverse osmosis filtration unit (10, 10A, 10B, 10C), wherein the pump unit (50, 50A, 50B, 50C) is configured to selectively pump the raw water in the raw water pipeline (L1) to the reverse osmosis filtration unit (10, 10A, 10B, 10C) according to a pressure in the product water outflow pipeline. The reverse osmosis filtration system (100, 100A, 100B, 100C) can operate stably even when a pressure in the raw water pipeline (L1) is low, can provide the operation stability of the reverse osmosis filtration system (100, 100A, 100B, 100C), and can realize on-demand water supply for the reverse osmosis filtration unit (10, 10A, 10B, 10C).
