Purified Water Vs. Drinking Water-The Difference

Purified Water using Reverse Osmosis (RO) Technology

Purified Water using Reverse Osmosis (RO) Technology is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as solvent molecules) to pass freely.

In the normal osmosis process, the solvent naturally moves from an area of low solute concentration (high water potential), through a membrane, to an area of high solute concentration (low water potential). The driving force for the movement of the solvent is the reduction in the free energy of the system when the difference in solvent concentration on either side of a membrane is reduced, generating osmotic pressure due to the solvent moving into the more concentrated solution. Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis. The process is similar to other membrane technology applications. However, key differences are found between reverse osmosis and filtration. The predominant removal mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically achieve perfect efficiency regardless of parameters such as the solution's pressure and concentration. Reverse osmosis also involves diffusion, making the process dependent on pressure, flow rate, and other conditions.[1] Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules.

How does reverse osmosis work?

Reverse osmosis (RO) is the most economical method of removing 90% to 99% of all contaminants. The pore structure of RO membranes is much tighter than UF membranes. RO membranes are capable of rejecting practically all particles, bacteria and organics , (including pyrogens). In fact, reverse osmosis technology is used by most leading water bottling plants.

Natural osmosis occurs when solutions with two different concentrations are separated by a semi-permeable membrane. Osmotic pressure drives water through the membrane; the water dilutes the more concentrated solution; and the end result is equilibrium.

In water purification systems, hydraulic pressure is applied to the concentrated solution to counteract the osmotic pressure. Pure water is driven from the concentrated solution and collected downstream of the membrane.Reverse osmosis is highly effective in removing several impurities from water such as total dissolved solids (TDS), turbidity, asbestos, lead and other toxic heavy metals, radium, and many dissolved organics. The process will also remove chlorinated pesticides and most heavier-weight VOCs. Reverse osmosis and activated carbon filtration are complementary processes. Combining them results in the most effective treatment against the broadest range of water impurities and contaminants.


Top 10 Benefits of Drinking Water

Top 10 Benefits of Drinking Water: Don’t Medicate, Hydrate!

1. Increases Energy & Relieves Fatigue

Since your brain is mostly water, drinking it helps you think, focus and concentrate better and be more alert. As an added bonus, your energy levels are also boosted!

2. Promotes Weight Loss

Removes by-products of fat, reduces eating intake (by filling up your tummy if consumed prior to meals), reduces hunger (hello natural appetite suppressant!), raises your metabolism and has zero calories!

3. Flushes Out Toxins

Gets rid of waste through sweat and urination which reduces the risk of kidney stones and UTI’s (urinary tract infections).

4. Improves Skin Complexion

Moisturizes your skin, keeps it fresh, soft, glowing and smooth. Gets rid of wrinkles. It’s the best anti-aging treatment around!

5. Maintains Regularity

Aids in digestion as water is essential to digest your food and prevents constipation.

6. Boosts Immune System

A water guzzler is less likely to get sick. And who wouldn’t rather feel healthy the majority of the time? Drinking plenty of water helps fight against flu, cancer and other ailments like heart attacks.

7. Natural Headache Remedy

Helps relieve and prevent headaches (migraines & back pains too!) which are commonly caused by dehydration.

8. Prevents Cramps & Sprains

Proper hydration helps keep joints lubricated and muscles more elastic so joint pain is less likely.

9. Puts You In A Good Mood

When the body is functioning at its best, you will feel great and be happy!

10. Save Money!

Water is FREE! Even if you choose bottled/filtered water, it’s STILL cheaper than that high sugar and fat-filled latte!
