While many times have you wanted to label as a process of osmosis filtration on a molecular scale is easy to understand and realize that reverse osmosis is a process clearly differentiated from the micro filtration or filtration.

There are three aspects which indicate clearly that this difference:
1. In the process of filtering the entire flow passes through the separator element. This only prevents the passage of solid particles of a predetermined size.
2. By contrast, reverse osmosis, only a portion of the feed rate through the membrane and constitutes the product. The remaining flow is discharged without passing through the membrane and becomes the rejection.
3. In reverse osmosis, never separated material accumulates on the surface of the membrane, as occurs in other processes, as is the rejection which is responsible for the drag of the material.
4. While the osmosis seawater flow is parallel to the membrane, filtration is perpendicular.
