Self-mediated saltless whole home water treatment systems and methods

A water treatment system, comprising:

• a prefiltration unit for filtering untreated water in fluid communication with a source of the untreated water, wherein the untreated water enters the prefiltration unit and the prefiltration unit produces a prefiltered water that exits the prefiltration unit;
• a pump in fluid communication with the prefiltration unit, wherein the pump selectively increases a flow rate of the prefiltered water in a first line;
• a membrane element for removing solutes from the prefiltered water in fluid communication with the pump via the first line, wherein the membrane element produces a permeate comprising the prefiltered water imparted with a first concentration of solutes and a retentate comprising the prefiltered water imparted with a second concentration of solutes, wherein the first concentration of solutes is less than the second concentration of solutes;
• a tank in fluid communication with the membrane element and the prefiltration unit, wherein the tank stores prefiltered water from the prefiltration unit and the permeate from the membrane element;
• one or more valves for regulating flow of the prefiltered water and the permeate;
• and
• one or more sensors, wherein a first sensor of the one or more sensors is positioned upstream of the membrane element and is adapted to measure a first characteristic of the prefiltered water.
