G3P600 Tankless RO System Combo Set - Waterdrop G3P600

The pure to drain ratio is 2:1, therefore, for every 2 cups of pure water you get, only 1 cup of wastewater is produced, which is much higher than the traditional RO systems.

The RO system offers faster water flow (600 gallons per day) and can filter a cup of water in about 8 seconds. Compared to traditional RO systems, the Waterdrop RO System has a low drain ratio of 2:1. Save more money on your water bills!

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to filter out impurities from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. The result is that the solute is retained on the pressurized side of the membrane and the pure water is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores, but should allow filtered clean water to pass freely.

A reverse osmosis system reduces sediment and chlorine from water with a prefilter before it forces water through a semipermeable membrane to reduce dissolved solids. After water exits the RO membrane, it passes through a postfilter to filter the drinking water before it enters a faucet.

All RO systems will produce concentrated water to discharge impurities. Compared to traditional RO water purifiers, Waterdrop RO system produces less concentrated water and saves 300% more water. You can collect concentrated water to mop the floor, wash your car, do laundry, etc.
