Water Filtration
How the water Filtration Works
1.A semi permeable membrane in a reverse osmosis system only allows certain things to pass through.
2.This membrane passes water easily but also prevents many other contaminants from passing by trapping them.
3.Water is normally on both sides of the membrane, the water on each side has a different concentration of dissolved minerals.
4.The water in the less concentrated solution tries to dilute the more concentrated solution.
5.Water will pass through the membrane from the lower concentration side to the greater concentration side.
6.The osmotic pressure (see diagram) created by the difference in water levels, will counter the diffusion process forming an equilibrium between the two sides.
Water Filtration Technical route and flow diagram instructions
The technical route is as following.
Raw tank-->Booster pump -->Quartz sand filter-->activated carbon filter--->Anti-scalant dosing-->Sediment filter-->High pressure pump-->Reverse osmosis desalination device-->Permeate tank
