<p>membrane because of an <a href="page.php?w=osmotic_pressure">osmotic pressure</a> difference is called <a href="page.php?w=osmosis">osmosis</a>. This allows only certain particles to go through including water and leaving behind the solutes including salt and other contaminants. In the process of <a href="page.php?w=reverse_osmosis">reverse osmosis</a>, water is purified by applying high pressure to a solution and thereby push water through a <a href="page.php?w=thin-film_composite_membrane">thin-film composite membrane</a> (TFC or TFM).
