Water Treatment System with Unibody design for easier installation, service, and reliability.

Unibody Design

RainSoft's patented Unibody design places all components, external tubing and water passageways in one easy-to-remove, top-manifold system. this allows for easier installation, service and reliability.

Superior Filtration

How Reverse Osmosis Works

As you may remember from your high school physics class, "osmosis" is a process in which a less concentrated fluid will diffuse through a semi-permeable membrane into a more concentrated fluid.

Osmosis is a natural process that occurs in living things. In plants, osmosis permits absorption of water and nutrients through the root system. In people, nutrients are absorbed into the blood stream by osmosis.

"Reverse Osmosis", as the name implies, acts in reverse fashion. When pressure is applied on a water supply, nearly pure H2O molecules are forced through a semi-permeable membrane to the other side, while impurities flow to the drain.

Operating Features

Drain shut-off valve. A control valve that shuts off the drain water when water pressure in the storage tank equals 80% of the line pressure.
Reversible, self-cleaning drain restrictor and easy fast-flush device.
Shut-off valve on pressurized storage tank allows user to change filters easily...without draining the storage tank.
Base of storage tank is removable, allowing tank to be installed on its side.
All filters, including R.O. cartridge, are easy to replace because of the unibody design. Filters need periodic replacement, depending upon the quality of the water supply.

System Components

SEDIMENT PRE-FILTER: A water filter that removes large particles and sediment over 20 microns in size from the supply stream.
R.O. CARTRIDGE: A spiral wound, thin film composite, semi-permeable membrane, reverse osmosis cartridge.
STORAGE TANK: A polyolefin R.O. water storage tank with a butyl bladder. It holds R.O. water on one side of its bladder and air on the other side.
CARBON POST-FILTER: An activated carbon filter that removes unwanted tastes, odors and other substances.
