5-Stage Reverse Osmosis System
50GPD Filmtec Membrane
4 Gallon Storage Tank
Complete System including Installation Kit!
Complete 5-Stage RO System for bottled quality water at your finger tips! Made in the USA
Most water supplies contain a wide range of contaminates that are not good for you. A lot of people solve this problem by buying bottled water, but bottled water can get expensive, not to mention the hassle of carrying it around and the problem of running out. The 5-stage RO system solves this problem, giving you bottled quality water at your finger tips! Our high quality RO system will ensure that your families drinking water is safe, and you never have to worry about going out to buy water again!
Complete 5-Stage System: This is a complete system, and comes pre-assembled, with filters, tank, faucet, and installation kit. All you have to do is hook it up!
Removes 95-97% of water contaminates:Including sodium, aluminum, lead, copper, arsenic, mercury, calcium, phosphate, iron, magnesium, zinc, chloride, nitrate, silicate, cyanide, sulphide, nickel, silver, bicarbonate, maganese, ammonium, barium, and chromium, as well as removing 95-97% of bacteria!
4 Gallon storage tank: The production rate of a 50 gpd membrane alone is about 2 gallons per hour, and most people don't want to wait that long to get their water, so this system includes a pressurized storage tank to store the water, giving you about 3.2 gallons of water available at any given time. This tank can be upgraded if you have a large demand for water.
High Rejection Filmtec 50GPD membrane: We use high quality Filmtec membranes in our RO system, one of the most trusted names for quality membranes.
Auto Shut-off valve: Includes an auto shut-off valve, which detects when the tank is full and shuts of the water supply to the membrane, conserving water.
Flow Restrictor: Regulates waste water, providing proper pressure against the membrane to ensure high effeciency
Check Valve: Prevents tank from pusshing water back through the membrane and down the drain, reducing waste.
Clear Housing for sediment filter: Helps you to monitor the condition of your sediment filter, making it easy to know when it needs changed.

How Reverse Osmosis Works
What is Reverse Osmosis?
Reverse osmosis, also known as hyperfiltration, is the finest filtration known. This process will allow the removal of particles as small as dissolved individual ions from a solution. Reverse osmosis is used to purify water and remove ions and dissolved organic molecules. It can be used to purify fluids such as ethanol and glycol, which will pass through the reverse osmosis membrane, while rejecting other ions and contaminants from passing. The most common use for reverse osmosis is in purifying water. It is used to produce water that meets the most demanding specifications that are currently in place.
Reverse Osmosis
Molecule Filtration
If two aqueous solutions of different salinity are separated by a semi-permeable membrane, osmosis will cause water to pass through the membrane in the direction of the more concentrated solution, therefore diluting it. By applying sufficient pressure to the more concentrated liquid, the direction of osmosis can be reversed. In this way, we can mechanically reverse the flow and separate the concentrated solution into its constituents: the water and the dissolved solids. One part is called the permeate, or filtrate, and the other is the reject stream, or concentrate.
How Does a Membrane Separate Substances?
Reverse osmosis uses a membrane that is semi-permeable, allowing the fluid that is being purified to pass through it, while rejecting the contaminants that remain. Most reverse osmosis technology uses a process known as crossflow to allow the membrane to continually clean itself. As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected species away from the membrane, in a concentrated brine reject water. The process of reverse osmosis requires a driving force to push the fluid through the membrane, and the most common force is pressure from a pump. The higher the pressure, the larger the driving force. As the concentration of the fluid being rejected increases, the driving force required to continue concentrating the fluid increases. Reverse osmosis is capable of rejecting bacteria, salts, sugars, proteins, particles, dyes, and other constituents that have a molecular weight of greater than 150-250 daltons. The separation of ions with reverse osmosis is aided by charged particles. This means that dissolved ions that carry a charge, such as salts, are more likely to be rejected by the membrane than those that are not charged, such as organics. The larger the charge and the larger the particle, the more likely it will be rejected

Size Comparison
Comparatively, if a water molecule were the size of a tennis ball........

Most metals and inorganic compounds would be the size of a softball;
Most organic compounds would be the size of a basketball;

Viruses would be the size of a bus

Bacteria would be the size of a pyramid; and...



Protozoa would be the size of Mount St. Helens!
