What is Reverse Osmosis (RO)?
Reverse osmosis (RO) is a membrane separation process in which feed water flows along the membrane surface under pressure. Purified water permeates the membrane and is collected, while the concentrated water, containing dissolved and undissolved material that does not flow through the membrane, is discharged to the drain.
The key requirements of Reverse Osmosis (RO) process are a membrane and water under a pressure. Other requirements include prefiltration to remove suspended impurities and carbon to remove chlorine (damages the membrane).
Most membranes remove 90-99+% of the dissolved impurities depending on the impurity and the composition of water.
Reverse osmosis systems (RO Systems) remove salts, microorganisms and many high molecular weight organics. System capacity depends on the water temperature, total dissolved solids in feed water, operating pressure and the overall recovery of the system.
Advantages of Reverse Osmosis Over Conventional Processes
Compared with other conventional water treatment processes, reverse osmosis has proven to be the most efficient means of removing salts, chemical contaminants and heavy metals, such as lead, from drinking water. For waters with total dissolved solids of 200 or more, reverse osmosis is less expensive than ion exchange. Even at total dissolved solids of less than 200, it is preferred over ion exchange for removal of silica and organics. Compared with distillation, reverse osmosis use only a fraction of the total energy and does not have high temperature problems or scaling and corrosion. Today reverse osmosis systems have proven to be the most economical and efficient means of improving the quality of water.
Home Reverse Osmosis Water Filtration Systems (Point-of-Use)
Tanano RO Systems provide a continuous supply of clean, fresh drinking water. Systems are assembled on a heavy-duty bracket for wall-mounting under the sink or in a nearby location.
Eliminate up to 96-98% of dissolved solids, chlorine, fluoride, microorganisms and heavy metals such as barium, cadmium, chromium, lead and mercury from your water. Use RO purified water for drinking, cooking & ice for improved flavor and increased health benefits.
System can be used to supply filtered water to a refrigerator ice-maker/water-dispenser by inserting a branch tee fitting (sold separately) between the post filter and the faucet.
Systems are equipped with automatic shut-off valves to eliminate waste by closing the feed line when the tank is full.
Quick-Connect in/out connection points for easy installation. Complete installation kit and product manual included with every system.
These compact under-the-counter systems are complete with pre filters and post filters and come with a 3.2 or 4 gallon storage tank and installation kit.
