Rowa “Merlin“

Under-the-sink direct flow osmosis

Direct flow - the next generation of water treatment!
The new Merlin RO System features continuous-flow water production, so a storage tank is no longer required. The unit operates on line pressure, which eliminates the need
for an electrical pump in most applications. The patented high-production, low-energy membrane reduces impurities in up to 2,816 liters of water per day!

Fits in nicely - the stand-alone compact profile takes up less space than other bulky systems. This high capacity performance creates new opportunities for commercial applications - at the price of a residential system.

Reverse osmosis is the process of pushing a solution through a filter that traps the solute on one side and allows the pure solvent to be obtained from the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membrane here is semi-permeable , meaning it allows the passage of solvent but not of solute.

The membranes used for reverse osmosis have no pores; rather, the separation takes place in a dense polymer layer of only microscopic thickness. In most cases the membrane is designed to only allow water to pass through. The water goes into solution in the polymer of which the membrane is manufactured, and crosses it by diffusion. This process requires that a high pressure be exerted on the high concentration side of the membrane, usually 2 - 14 bar (30 - 200 pounds per square inch) for fresh and brackish water, and 40 - 70 bar [(600 - 1000 psig)] for seawater, which has around 24 Bar (350 psi) natural osmotic pressure which must be overcome.

Our water purification systems are reverse osmosis machines that produce pure water. It does this by passing tap water through a special membrane. Reverse Osmosis - (R.O.) is a fancy-sounding name to describe what is essentially a simple process. It is a special hyperfiltration whereby water is forced under high pressure against a semi-permeable membrane. The end result is water so pure and tasty, that even natural sources can rarely match it.
