Abstract:
The improved water purification system includes a water purification unit having a tap water inflow port for receiving a tap water inflow from a water supply system to produce relatively purified water and a brine water outflow having impurities concentrated therein. An RO filter having an RO membrane separates relatively unfiltered water flow into purified water and the brine water outflow. A flush flow activation chamber fluidly coupled to the brine water outflow includes a plunger for substantially occluding brine water outflow through the brine outflow port when seated, and substantially permits brine water outflow to exit the purification unit through the brine outflow port when unseated. Accordingly, the activation chamber generates back pressure within the water purification system to flash flow tap water inflow into the purification unit and through the RO membrane when the plunger moves from being seated to unseated, thereby substantially refreshing said RO membrane.

Claim (Index 11):
An automatic flush flow for a water purification unit, comprising:\n a flush flow activation chamber comprising a substantially vertical tube that is fluidly coupled to a reverse osmosis (RO) filter to receive a brine water outflow at a top of the substantially vertical tube, and to drain through an aperture at a bottom of said substantially vertical tube, the substantially vertical tube having a float plunger therein for substantially occluding said brine water outflow through the aperture to a brine outflow port when in a first float seated position, and substantially permitting said brine water outflow to exit a water purification unit through said brine outflow port when in a second float unseated position; wherein when the water purification unit is not producing purified water or filling a reservoir, increased pressurization within the water purification unit allows the float to rise to the top of the vertical tube to the first float seated position, wherein when the water purification unit is producing purified water, pressure drops in the RO filter to create back pressure at the bottom of said substantially vertical tube until the back pressure reaches a float threshold level that draws the float out of the first float seated position to a second float unseated position, and wherein water draining from the vertical tube through the aperture when said float moves from said first position to said second position generates back pressure on the RO filter to produce a sudden increase of inflow through the tap water inflow, the increase of inflow to flush flow said tap water inflow through an RO membrane in the RO filter, thereby refreshing said RO membrane.
