2.1. WHAT IS REVERSE OSMOSIS?
It is the best method currently available for producing pure water by means of a physical system (without the
use of chemical products). Its principle of operation is the same as that of the human body, in which water is
distributed through natural osmosis, which separates the impurities from the water purifying it.
A high percentage of the human body is composed of water:
- Women: 55-65%
- Men: 65-75%
- Children: 80%
The body of an adult contains between 38 and 48 litres of water, 40% of which can be found in the cells. This
water in the body, which is almost completely recycled every two weeks, plays a fundamental role in the
transportation of nutrients and oxygen to the cells, the elimination of waste and control of the body temperature.
Every day we consume an average of 2.2 litres of water, including the water contained in food.
2.2. HOW DOES THE MEMBRANE OF YOUR ALISON REVERSE OSMOSIS WORKS ?
Let us try to explain the principle of reverse osmosis easily.
Th e wa te r ex er ts pr es su re on a se m i- pe rm ea bl e
membrane, so that part of the water will go through the
pores of the membrane (pure or osmotized water), while
the remainder (rejected or concentrated water) will be
diverted to the drain.
Given that the diameter of the pores of the membrane is
less than 0.0001 microns, only the pure water and a
balanced quantity of minerals (sodium, potassium, calcium,
magnesium, etc.) will be able to pass through it, while the
excess of minerals not required by the body will be
eliminated during the process, together with bacteria,
viruses, heavy metals, pesticides, chemical products, etc.
2. INTRODUCTION
THE ALISON REVERSE OSMOSIS UNlTS OFFER YOU A BETTER QUALITY OF LlFE
You will notice an improvement in the taste of your drinking water, and you can prepare better coffee, ice
cubes and juices. Cooking with the purified water will improve the taste of food, and the water will be healthier
for your children and good for your plants. It is very healthy for patients suffering from hypertension, since this
water is low in minerals. Ideal for steam irons and dehumidifiers, osmotized water will help to prolong the life
of your household appliances.
