Wastewater recycling - Import export

The reverse osmosis is a process of "filtration by means of semipermeable membranes". This process allows starting from salt water to produce pure water, in fact, by exerting a pressure greater than the osmotic cancels the natural tendency that have two solutions at different concentration, in the presence of semi-permeable membrane, the pure water to migrate towards that salt. Its main application is the filtration of saline waters, whether of aqueduct or well water, for the production of high quality demineralized water. The reverse osmosis is also applied in the treatment of wastewater for the partial recycling of the same. The reverse osmosis systems are extremely versatile, with modular flow depending on the capacity required. Through "two-stage process", it is also possible to produce ultrapure water. The main application of reverse osmosis is the deionization OF PRIMARY WATERS.
