(eg. 60 watts, a typical rating for an incandescent light bulb; or 13 watts, the rating for a compact fluorescent light bulb with light output comparable to a traditional 60 watt light bulb.). Ad.
What is RO? Reverse Osmosis (RO) is the process to have clean and pure water through a permeable or semi-permeable membrane. In Reverse Osmosis, pressure is used to force a solution through membrane. The solute remains on the one side and the solvent passes through the membrane to other side.
Low pressure RO systems generally refer to those systems with a water feed pressure of less than 100 psig. These are the typical countertop or undersink residential systems that rely primarily on the natural water pressure to make the reverse osmosis process function; a typical system is shown schematically below.
