Treating reverse osmosis water with Roxtract Ionized Mineral Solution
will replace the valuable minerals that the process of reverse osmosis removes!
Did you know that reverse osmosis wastes 2 to 3 gallons of water for every gallon it produces wasting one of earth's most valuable natural resources!
Did you know that Reverse Osmosis was originally developed to desalinate sea water and for use in photo and print shops.
The process of reverse osmosis was not originally intended to be used as drinking water!
Reverse osmosis refers to a process of water purification that was developed primarily for the desalination of seawater and to be used for photo and print shops!
To understand reverse osmosis, it
is first necessary to understand osmosis. Osmosis is the term for the phenomenon
whereby if a semi-permeable membrane separates two salt solutions of different
concentration, water will migrate from the weaker solution through the membrane
to the stronger solution, until the solutions are of the same salt
concentration. Reverse osmosis subverts this process. It involves applying
pressure to reverse the natural flow of water, forcing the water to move from
the more concentrated solution to the weaker. The semi-permeable membrane is
porous, allowing water to pass through, but blocking the passage of the bulkier
The semi-permeable membranes for reverse osmosis treatment are generally constructed from polyamide-based materials. These materials are resistant to biological degradations, but are subject to chemical attacks from chlorine.
Reverse osmosis has been used as a method of purification for ground and surface fresh water, in addition to its role as a desalinating agent. Working with such water sources creates some problems for the reverse osmosis system. Because of the very small pore sizes involved in the membrane, it is vital that ground and surface water is adequately pre-treated prior to the reverse osmosis process. Depending upon the hardness of the water involved, scaling of the membrane is likely to occur. If the concentration of the calcium or magnesium in the water (the chemicals that determine water’s hardness) is at a high enough level where the chemicals are insoluble, it will create a hard mineral on the inside of the membrane, rendering it useless.
|Upside(s) of Reverse Osmosis|
semi-permeable membrane used in reverse osmosis contains tiny pores through
which water can flow. The small pores of this membrane are restrictive to
such organic compounds as salt and other natural minerals, which generally
have a larger molecular composition than water. These pores are also
restrictive to bacteria and disease-causing pathogens. Thus, reverse osmosis
is incredibly effective at desalinating water and providing
mineral-free water for use in
photo or print shops. It is also effective at providing pathogen-free water.
In areas not receiving municipally treated water or at particular risk of
waterborne diseases, reverse osmosis is an ideal process of contaminant
|Downside(s) of Reverse Osmosis|
The reverse osmosis process contains several downsides which make it an inefficient and ineffective means of purifying drinking water. The small pores in the membrane block particles of large molecular structure like salt, but more dangerous chemicals like pesticides, herbicides, and chlorine are molecularly smaller than water. These chemicals can freely pass through the porous membrane. For this reason, a carbon filter must be used as a complimentary measure to provide safe drinking water from the reverse osmosis process. Such chemicals are the major contaminants of drinking water after municipal treatment.
Another downside to reverse osmosis as a method of purifying drinking water is the removal of healthy, naturally occurring minerals in water. The membrane of a reverse osmosis system is impermeable to natural trace minerals. These minerals not only provide a good taste to water, but they also serve a vital function in the body’s system. Water, when stripped of these trace minerals, can actually be unhealthy for the body.
Reverse osmosis also wastes a large portion of the water that runs through its system. It generally wastes two to three gallons of water for every gallon of purified water it produces. Reverse osmosis is also an incredibly slow process when compared to other water treatment alternatives.
|What Chemicals Does Reverse Osmosis Reduce or Remove|
Reverse osmosis will generally remove any molecular compounds smaller in
size than water molecules. Such compounds include salt, manganese, iron,
fluoride, lead, and calcium. Reverse osmosis is extremely efficient at
stripping minerals from water, and it is highly valued as a water
purification process in the printing industry, in which mineral-free water
must be used.
Although reverse osmosis supplies useful, mineral-free water for printing purposes, it does not provide the healthiest drinking water. Reverse osmosis will remove several mineral and chemical materials from water, including salt, fluoride, lead, manganese, iron, and calcium. Reverse osmosis, because it removes minerals according to physical size, is non-selective in its removal of dangerous and beneficial minerals. Clearly, mineral contaminants like salt, fluoride, and lead should be removed from drinking water, but minerals like iron and manganese, because they are essential to natural body processes and important components of drinking water, should be left in that water.
