All solution through the filter medium, only a the water out. This kind of filter often referred to as the endpoint, including security filter, bag filter, sand filter and filter medium. The filter method is generally limited to the suspended particles larger than 1 micron in diameter. To remove a small diameter less than 1 micron particles, colloidal substance, humus and soluble salt, another to divide & ndash; — Membrane began to be used, particles by reverse osmosis intercept rather than stay in the filter medium, reverse osmosis membrane surface not only can intercept and substrate itself also selective adsorption particles. In addition the process water flows along the membrane surface, part of the water through a permeable membrane, the left most of the salt in the water. Because the water will flow through the membrane surface in a row, trapped particles will not deposit, will be washed away.
