RO Systems
Reverse Osmosis can be described as a semi permeable membrane that will allow a small flow of pressurized water flowing across the membrane to pass (flow) through the membrane, while blocking the passage of salt ions and suspended solids (dirt). In order to reduce the possibility of these materials from being trapped on the membrane (filter) surface, only a portion of the solution is purified (filtered).
The water passing through the membrane is removed from the system and called "permeate". This solution is virtually free of charged ions or salts and suspended solids. The solution passing across the membrane now contains the charged ions and suspended solids left behind by the permeate and is either recycled or removed from the system. This solution is now called "concentrate".
By design and through the use of valving, the amount of permeate produced from the feed water is expressed as % recovery and is generally in the range of 50-75%.
Through todayʼs advanced membrane technology, systems can be designed to filter out over 99.5% of all total dissolved solids. The wide variety of membranes available (low pressure high rejection chlorotolerant) allow the system designer to produce equipment that is better suited to the specific needs of a project. Current RO systems utilize membranes which have a higher filtering of ionic material at lower pressures, thereby producing higher quality output at lower operating costs.
