The remineralization stage is an additional feature of this water purifier. The name itself explains the function of this stage. After passing through the basic 5 stages of filtration the water is treated in the remineralization stage. At this point of purification, some advantageous minerals restored into the water again. The added minerals improve the taste and raise the pH to more alkaline. You will definitely enjoy the fresher tasting mineral water.
One way to disinfect water through solar purification is through the use of plastic bottles and sunlight. Remove all labels and paper from the bottles and ensure they have no scratches. Fill them with water to about three quarters full, shake for a half-minute to activate the oxygen, fill with water to the brim, cover, and then lay it horizontally and expose to direct sunlight (Water Benefits Health).
The pore size of the filter, usually measured in microns, will determine what will be filtered through. While a standard micron size of 0.2 is small enough to block heavy metals such as lead and copper and large parasites such as Cryptosporidium, it will not block viruses. The National Sanitation Foundation sets a standard for effective water filtration products so look for an NSF stamp when selecting a filter to purchase.

But the efficient reverse osmosis systems that we have reviewed, demands the filter change after every 6-12 Months. Pre-membrane filters and the post-filter changing duration depends on the quality of feed water and the RO filter that you have. The RO Membrane has the lifespan of 2-3 Years and in some cases, it can last even 4 years. RO systems filter demands only 10 minutes after every 6 months and RO Membrane will take your 20 Minutes a year for maintenance, rest of the osmosis water filter is maintenance-free. You have to follow all these instructions for keeping it as a best reverse osmosis system.

The desalinated water is stabilized to protect downstream pipelines and storage, usually by adding lime or caustic soda to prevent corrosion of concrete-lined surfaces. Liming material is used to adjust pH between 6.8 and 8.1 to meet the potable water specifications, primarily for effective disinfection and for corrosion control. Remineralisation may be needed to replace minerals removed from the water by desalination. Although this process has proved to be costly and not very convenient if it is intended to meet mineral demand by humans and plants. The very same mineral demand that freshwater sources provided previously. For instance water from Israel's national water carrier typically contains dissolved magnesium levels of 20 to 25 mg/liter, while water from the Ashkelon plant has no magnesium. After farmers used this water, magnesium-deficiency symptoms appeared in crops, including tomatoes, basil, and flowers, and had to be remedied by fertilization. Current Israeli drinking water standards set a minimum calcium level of 20 mg/liter. The postdesalination treatment in the Ashkelon plant uses sulfuric acid to dissolve calcite (limestone), resulting in calcium concentration of 40 to 46 mg/liter. This is still lower than the 45 to 60 mg/liter found in typical Israeli fresh water.

Ultraviolet light (UV) is very effective at inactivating cysts, in low turbidity water. UV light's disinfection effectiveness decreases as turbidity increases, a result of the absorption, scattering, and shadowing caused by the suspended solids. The main disadvantage to the use of UV radiation is that, like ozone treatment, it leaves no residual disinfectant in the water; therefore, it is sometimes necessary to add a residual disinfectant after the primary disinfection process. This is often done through the addition of chloramines, discussed above as a primary disinfectant. When used in this manner, chloramines provide an effective residual disinfectant with very few of the negative effects of chlorination.


Remove heavy metals with cilantro. Just as pine trees are effective at removing pathogens, so too is cilantro excellent at removing heavy metals from water. Fill a pitcher with water and place a handful of cilantro leaves into the pitcher. Stir the water and let the leaves sit in the water for at least an hour. Remove and discard the cilantro before drinking the water.[11]
Chlorine is a powerful chemical that has been in use for many years to treat water for home consumption. Chlorine is an effective water purification method that kills germs, parasites and other disease-causing organisms found in ground or tap water. Water can be purified using chlorine tablets or liquid chlorine. As an off-the-shelf water purification product, chlorine is cheap and effective. However, caution should be taken when using chlorine liquid or tablets to treat drinking water. For example, people suffering from thyroid problems should talk to a medical practitioner before using this product. When using chlorine tablets, it is important to apply them in heated water, as they dissolve well in water that is at 21 degree Celsius or higher. Chlorine tablets kill all bacteria leaving your water clean and safe.
