3What is osmosis? Under normal pressure, solution passes from one side to the other until it is equal
4Osmosis: The movement of water across a semi permeable membrane Osmosis: The movement of water across a semi permeable membrane. Osmosis is the movement of water (red dots) through a semipermeable membrane to a higher concentration of solutes (blue dots).
8a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
9What Is Reverse Osmosis and How Does It Work? Seabirds use reverse osmosis to desalinate seawater. They possess a membrane in their throats which allows water molecules to get through and stops the salt. This enables them to drink fresh, unsalted water, and they spit out the salty waste.Humans worked out how to copy this process around 40 years ago for the same reason - to desalinate seawater.When applied pressure exceeds the osmosis pressure, Reverse Osmosis will take place.In the Reverse Osmosis situation, water passes through the membrane to the diluted solution leaving behind dissolved particles.(in this case salt)

19Reverse osmosis is a type of water purification technology. It is not a filtration system, but rather a membrane technology usually used to remove salt from seawater, a process called desalination.
20Truth About Reverse Osmosis water Is it Safe to Drink the Water?
21Yes, Reverse Osmosis water is very clean and good for our bodies.
22Some people claimed to say that RO water is too pure and clean to be good because such perfectly clean mineral-free water does not exist naturally on earth. They forgot about a great thing called RAIN.Rainwater is water that has been stripped of all minerals and is one of the purest and cleanest water on earth. Human beings have relied on drinking rainwater for thousands of years without any negative health effects. Only recently has rainwater been polluted by the industrial age and man’s pollution of the skies. Ask yourself this. What can be more natural than mother-nature’s life giving rain?With all the scientific research that has been done over the years on reverse osmosis water, none has ever documented any negative health effects from water treated by this method.
23Some more facts to consider. 1. Bottled Water = RO Water.When you drink many brands of bottled water, you are actually drinking RO treated tap water.2. Soft Drinks = RO Water.When you drink soft-drinks and soda, you are drinking mineral-free treated RO water. Vitamin water, sports drinks & energy drinks are also made from RO purified water
24Reverse osmosis is now used in medicine and industry as a means of purifying or separating water and other solvents from other components. In recent years, it has been used increasingly for making pure water for dialysis in hospitals and for producing Water for Injection.
25The truth is many of us have been using and drinking reverse osmosis water in significant part of our lives without even knowing it.
26St. Eustatius water production process The source for our drinking water production comes from the sea, via a well.By the use of wells, instead of direct sea water gives your membrane with a longer life. Reduces the ppm
37The Brackish water will pass thru the second sets of membranes performing the same process, purifying the brackish water into fresh water. (Permeate)The permeate water will then be stored in a buffer tank. Untreated water.
38The permeate water would then be transfer to a holding tank while being treated with chlorine and calcium by flowing thru a calcite media filter.
