The permeate stream (product water) goes to the storage tank, and the waste stream with all the contaminants and dissolved inorganics goes to drain (also called concentrate stream or RO reject water). In reverse osmosis, there is cross-flow filtration through the membrane. This is known as Osmotic Pressure () and is calculated by the equation ( . This duo makes for great-tasting drinking water.
