Reverse osmosis is used for many varied purposes. But perhaps the area where you take more out, is the process of desalination of seawater. It is used for industrial tasks and to generate potable water, among other purposes. The membranes are manufactured today have a degree of salt rejection very best, rising 99.4 to 99.6%. Thus, it is easy, economical and effective to achieve low-saline waters. Besides its benefit to any type of urbanization, this system is highly necessary in those remote communities, where water does not come, is scarce or very expensive.
To achieve this water with low concentration of salt is carried out a very interesting biological process. By means of a feed pump, salt water is captured to be treated. Then this is transferred to pre-treatment units, where chemical processes take place dosing fluid components and physical treatments of filtration, filtration multilayer and fine sand with sticks. After the water is pre-treated in these units, moves into the membranes with a high pressure pump. Here we carry out the reverse osmosis process. Shall be from side fluid low salt content (also called permeate), and secondly the current high concentration of salts (or rejection).

Researchers at the Institute of Chemical Technology, the Joint Council for Scientific Research (CSIC) and Universidad Politécnica de Valencia, have patented a new catalyst based on gold nanoparticles that are capable of carrying out the reaction for the formation of aromatic azocompuestos without generating toxic waste. These molecules are used as coloring agents, food additives and pharmaceuticals.
At work, which is published in the latest issue of the journal Science, scientists have been facing a problem that has chemical interest from the standpoint of basic research and its implications for industrial and social get azocompuestos so environmentally responsible.

The Atlantic stores 13% more carbon dioxide anthropogenic (caused by human activity) which is thought to date. Is the conclusion of an international study in which researchers have taken part of the Higher Council for Scientific Research (CSIC) and concluding that the amount of anthropogenic CO2 in the Atlantic is 54 GtC, instead of the estimated 47 to date (each gigatonnes are 1015 grams). Ie that the measurements obtained in the late twentieth century were 13% undervalued. The investigation, which is part of the project CARBOOCEAN of the European Union, published in the journal Biogeosciences.
The study was conducted in the Atlantic Ocean for its important role in global ocean circulation and ocean as the largest amount of CO2 stored with respect to its total volume. However, according to researcher Marcos Vazquez CSIC, Institute of Marine Research in Vigo, "the findings are extrapolated to any other of the world ocean, so the overall amount of carbon stored may be larger than estimated so far" .
