Reverse Osmosis Water Filters explained
If you home drinking water comes from a municipal or city water system, then the tap water you drink comes through a real maze of filtration procedures before it reaches your faucet. The water enters into the main water system without any purification at all, from where it’s passed through a filtration process of sand, synthetic floss, fine gravel, or all 3 combined.
This filtration process removes sediment particles, and some cloudiness. Further down the pipe, Granular Activated Carbon take harmful toxins out of the purified water, in a system procedure known as chemical filtration. The final filtration stage is biological water filtration. Some water treatment plants also have their purified water go through plant life, to remove (absorb) nitrates and other nitrogen from the water.
A similar filtration process may be seen in home aquariums.
To clean the water where your fish live and grow, water purification is necessary. In many instances the aquarium water is taken into the intake pipe and then sent through a layer of fine string wound filters, to remove particles and the waste the fish leave. Then a layer of granular activated carbon is used as the chemical filtration process. Finally, bacteria known as nitrobacters are existent on the filter string and plants to take in ammonia and nitrite which comes alive from left fish-food and fish waste. Generally, a human drinking water treatment system is a macrocosm of this aquarium system.
A city water treatment facility would usually add chlorine to the treated water to remove any pollutants from outside of the facility on the purified water’s way to your tap. When it comes to removing (by actually killing) everything bad in drinking water, Chlorine would be like a neutron bomb for this task. Many municipal areas add Chloramine as a supplement to add more power when the water pumping systems are known to have larger tracts of bacteria. Chlorine and Chloramine, eradicate all bacteria. On the other hand, in large volumes, they are nothing less than simply poison in water.
Now, as the water reaches your tap, home water filters remove chlorine via carbon and other means. Many water filters have more than one feature in water purification, they rang from GAC (granular activated carbon), Ultraviolet light UV water purification, and Reverse Osmosis.
- carbon is a simple way to filter tap water. Granules of carbon would filter our harmful substances such as like chlorine from drinking water. With water filter systems that use carbon, often there is a second filtration process (used first in series) to eliminate sediment particles from the pipes. Some drinking water filtration manufacturers often provide many layers of filtration. This may include carbon, sediment, or a Ultraviolet UV lamp.
- Next is ultraviolet light. UV light deactivate bacteria. A unit with a UV bulb is placed at the center of the water passage, where the water is exposed to the light. Although UV light looks neat, it is only effective at removing (or deactivating by killing) bacteria and living germs, but does nothing for other contaminants such as chlorine and sediment etc.
- One of the best methods of water filtration is reverse osmosis. This is so unique that it has been referred to as hyper-filtration. Drinking Water goes through a RO membrane that can remove almost anything. To ensure the membrane works properly, there are also pre-filtration units, as well as a storage tank for the RO purified water. This RO system is not as costly as many think, but it could take up space. It’s a miniature drinking water treatment plant below your kitchen sink!
Those using city or municipal water may wish to contact the local water municipality to receive a report of the water reading, which is usually free. It would also provide details if the water contains fluoride, see the level of nitrates, phosphates, and other bad things that might come in from the water plant to the faucet.
Saltwater would have a pH of approximately 8.4. On the other hand:
Reverse osmosis water would generally have a pH of 6.
If it’s below 7.0 pH, it is acidic water.
According to many, acidic water is not too good long term, and should not be consumed.
If it is above, it’s alkaline water.
Spring water is supposed to be on the alkaline side due to its dissolved minerals.
An aquarium pH test kit may be a great help. These don’t cost too much, and would provide clues about the water you’re drinking.
