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.
