How Reverse Osmosis Works:

A semi permeable membrane, like the membrane of a cell wall or a bladder, is selective about what it allows to pass through, and what it prevents from passing. These membranes in general pass water very easily because of its small molecular size; but also prevent many other contaminants from passing by trapping them. Water will typically be present on both sides of the membrane, with each side having a different concentration of dissolved minerals. Since the water in the less concentrated solution seeks to dilute the more concentrated solution, water will pass through the membrane from the lower concentration side to the greater concentration side. Eventually, osmotic pressure (seen in the diagram below as the pressure created by the difference in water levels) will counter the diffusion process exactly, and an equilibrium will form.

Normal Osmosis

The process of reverse osmosis forces water with a greater concentration of contaminants (the source water) into a tank containing water with an extremely low concentration of contaminants (the processed water). High water pressure on the source side is used to "reverse" the natural osmotic process, with the semi-permeable membrane still permitting the passage of water while rejecting most of the other contaminants. The specific process through which this occurs is called ion exclusion, in which a concentration of ions at the membrane surface from a barrier that allows other water molecules to pass through while excluding other substances.

Reverse Osmosis

Semipermeable membranes have come a long way from the natural pig bladders used in the earlier osmosis experiments. Before the 1960's, these membranes were too inefficient, expensive, and unreliable for practical applications outside the laboratory. Modern advances in synthetic materials have generally solved these problems, allowing membranes to become highly efficient at rejecting contaminants, and making them tough enough to withstand the greater pressures necessary for efficient operation.

Even with these advances, the "reject" water on the source side of a Reverse Osmosis (RO) system must be periodically flushed in order to keep it from becoming so concentrated that it forms a scale on the membrane itself. RO systems also typically require a carbon prefilter for the reduction of chlorine, which can damage an RO membrane; and a sediment prefilter is always required to ensure that fine suspended materials in the source water do not permanently clog the membrane.

How Does a Permeate Pump Work?:

A permeate pump uses the energy of the brine water of your Reverse Osmosis system, to pump the permeate into your pressure Tank. It does not require electricity for that. It is just useing hydraulic energy that normaly goes to drain unused.

In doing so, it isolates your Tank from the membrane and lets your membrane perform like in an athmospheric tank system. See the animation below which depicts this.

Champ HR-3 (pictured below).

Clean, great tasting water at your fingertips.

This high-recovery unit utilizes a non-electric energy recovery device, called a permeate pump, which dramatically improves the efficiency on an R/O System. This unit will improve recovery by as much as 400% and reduces waste water by 80%. The Champ HR-3 also prevents TDS creep, increases the life of the membrane and fills tanks four times faster.

Improves Recovery Rate By As Much As 400%
