Reverse Osmosis is the reversal of the natural flow of osmosis. In a water purification system, the goal is not to dilute the salt solution, but to separate the pure water from the salt and other contaminants. When the natural osmotic flow is reversed, water from the salt solution is forced through the membrane in the opposite direction by application of pressure-thus the term REVERSE OSMOSIS.Through this process, we are able to produce pure water by screening out the salts and other contaminants.
There are two major differences:
The membrane consists of several thin layers or sheets of film that are bonded together and rolled in a spiral configuration around a plastic tub (This is also known as a thin film composite or TFC membrane.) The material of the membrane is semipermeable : it allows water molecules pass through while acting as a barrier to dissolved solids (i.e.: mineral chemical contaminants). When the feed water stream passes across the surface of the membrane, the PurePro molecules penetrate the membrane surface, working their way around the spiral and collecting in the center tube. The remaining contaminants are concentrated and washed from the surface of the membrane down the drain.
Assume a membrane is semipermeable, allowing water to pass through while being closed to dissolved salts. Place a membrane between two compartments in a container as shown in the figure to the right. Then place a salt solution in one half of the container and pure water in the other half. Now a fundamental scientific principle comes into play. That is, two different concentrations of liquids within the same system will try to reach equilibrium (i.e. the same concentration of contaminants) on both sides of the membrane. Of course the only way for this to happen is for pure water to pass through the membrane to the salt water side in an attempt to reach equilibrium is called OSMOSIS.
YES! Reverse Osmosis was originally designed to make sea water drinkable for the navy. It is ideal for anyone on a low sodium diet.
YES! An R.O. membrane has a pore size much smaller than bacteria virus, pyrogen or the cryptosporidium parasite. When functioning properly it will remove all microorganisms from tap water and produce sterile water .
One indication is a gradual reduction in water production caused by a layering of minerals and salts on the membrane surface. Another is a gradual deterioration in the quality of water being produced. You my notice a different taste or more white scum on the inside of a pan of water you are boiling. This might mean the R.O. membrane is disintegrating and requires replacement. (Note: Water Quality Tester TDSX1 help you to know when you should change the R.O. membrane or the best buy unit (RO103TDS).
There are four major variables to consider:
1. PRESSURE. The greater the water pressure, the better the quantity and quality of the water produced. Water pressure of 60 psi ideal. PurePro include one booster pump can make sure the water pressure.
2.TEMPERATURE. 76*F is the ideal water temperature for R.O. 40*F water will cause the production of R.O. water to fall to half of that at 76*F. The maximum water temperature recommended is 85*F.
3.TOTAL DISSOLVED SOLIDS (TDS). The higher the amount of dissolved contaminants in the water, the lower the quantity of water produced. A high level of TOTAL DISSOLVED SOLIDS can be overcome with additional water pressure.
4. MEMBRANE. Different membranes have different characteristics. Some produce more water than others; some have better contaminant rejection capabilities; some have greater resistance to chemical abrasion for longer life. PurePro system comes with TW30-1812-80 The Thin Film Composite(TFC) membranes combine the best of these characteristics and are considered the finest membrane in the world
Answer : Total Dissolved Solids is a measure of dissolved inorganic substances in water. It is measured in mg/L or ppm
Answer : Dissolved Impurities such as Pesticides, Rust, Heavy Metals, Arsenic, and Fluoride etc. are harmful for Human Body. They also spoil the taste of water. The water becomes healthy as well as tasty when these dissolved impurities are reduced from water by using the right water purifier.
Answer : Boiling kills bacteria and viruses but does not remove harmful dissolved impurities such as Pesticides, Rust, Heavy Metals, Arsenic, Fluoride etc. Boiling water only helps you remove the physical impurities that are present in water. Presence of such impurities in water may cause serious diseases such as cholera, hepatitis A & B, jaundice, typhoid and even cancer.
Answer : The most commonly used methods of purification are (A) Ultra Violet Based Technology (B) Reverse Osmosis Technology (C) Resin Based like Chlorine, Bromine and Iodine. (D) Traditional Methods like Filtration by Cloth, Boiling and Alum etc.
Answer : Water contains physical, chemical and micro-biological impurities which is adsorbed & arrested depending on the type of impurities. Hence the water after passing through the purification stages which is between 5-9 stages in case of RO purifier, is pure & safe drinking water.
Answer : It is necessary that you need to get your water tested to find out what water condition you are faced with, before you buy a purifier. Based on the results you can pick a purifier that is equipped with the right technology to treat your water.
Answer : Dissolved Impurities such as Pesticides, Rust, Heavy Metals, Arsenic, and Fluoride etc. are harmful for Human Body. They also spoil the taste of water. The water becomes healthy as well as tasty when these dissolved impurities are reduced from water by using RO water purifier.
Answer : No. All Pure-Pro RO Waterpurifiers run on electicity. However, water can be dispensed manually in case of power cut.
Answer : The consumption of electricity in water purifiers is negligible. It has a power consumption of 30 watts. Power consumption may vary slightly for different models.
Answer : The rejected water can be used for household purposes like washing utensils, watering plants, mopping, cleaning, etc.
Answer : It is not recommended to open your Pure-Pro RO and service it by an untrained individual. Call our AMIO WATER customer support number 01730 316893 for any issues related to service & re-installation the machine.
