Quality purification requires time, so the output from using reverse osmosis water filter systems is relatively small. The water in reverse osmosis water filter systems must pass through several stages of purification to achieve the most effective and efficient level of purification. Pre-treatment in reverse osmosis water filter systems is critical. The reverse osmosis membrane is the most expensive and sensitive part of the reverse osmosis water filter system and is protected and preserved by sediment and carbon filters.
The slowest stage in reverse osmosis water filter systems is the passage through the reverse osmosis membrane. The rate of passage of molecules through the reverse osmosis membrane is dependent on several factors, the most important of which is the fluid pressure. Then, there is the concentration of impurities in the water, as well as the temperature, and the degree of permeability of the reverse osmosis membrane itself.
