Bottled Water:
Sachet water would have been the solution to clean water but considering the carelessness of the sachet water vendors, it is risky to trust them. The Bottled/sachet water industries are not regulated by the government, although they all parade NAFDAC number, all tests conducted on bottled/sachet water samples collected from various locations proved that bacteria still exist in these water sources. This is because some of the sachet water vendors are mostly interested in their profit, thereby neglecting the required hygiene needed for such consumable product.
Water Treatment Plant:
It is widely used by people with little knowledge about its process. Hence, in attempt to prepare the water, the operator adds excess chlorine and other water treatment chemicals. These chemical not only become impurity in the water after filtration, chlorine and/or other chemicals give the water awful taste. In a nutshell, Water treatmet plant is required in industries where such treated water is required in manufacturing.
Filters:
Filters can improve the taste of water by removing impurities like dust, color, ordor and chemicals; it has no independent ability to kill or remove pathogens from the water. These pathogens are the causative organism of most illnesses that gradually reduce human life span to 60-70yrs. If you can afford to drink clean and sterilized water for the rest of your life, you will live longer than your ancestors.
Reverse Osmosis:
Reverse osmosis is a water treatment method used by industries, for purification of water needed for manufacturing purposes. For example, an iceblock industry managed by a chemist will prefer reverse osmosis for the treatment of their raw material which is water.
Why would they treat their water before freezing? Well, scientifically we came to understand that a clean water will freeze into ice once the temperature of that water becomes 0~degree centigrade.
To freeze water to ice, you must need electrical energy to power your freezers, and you would not want to waste your electrical bills freezing water that will take a very long time to freeze simply because it contains salt and other water soluble elements with various freezing point; instead, you will ask an expert to give you a solution so you can make profit from your business. The solution would be REVERSE OSMOSIS method, DISTILLATION method or other suitable water treatment method.
In summary, Reverse Osmosis is not an approved method of water treatment required for drinking because it does not kill water-borne diseases. In addition, it is costly, wasteful and time consuming. It delivers only few gallons per day.
Alums and other Water softeners
This is never an approved method of water treatment because water softener does not kill bacteria. 'Alum' for example, was introduced in the olden days when humans have no solution for dirty water. In those days, colored water like red-flood is preserved for domestic used. If you drop alum into this water, the physical reaction between alum and every impurity in the water will lead to sedimentation, i.e. all the dust and particles in that water will settle at the bottom of the containing vessel, and the water will relatively look like water. This does not make this water safe for drinking because alum simply enhances sedimentation of sands, dust and muds in any water source but it does not kill bacteria and other harmful germs in a dirty water.
Distillation
Distilled water is good for cooking and bathing purposes only, and not for drinking because boiled or distilled water will reduce intake of calcium, phosphorus and other vital elements necessary for the maintenance and healthy life of your bones.
Boiled Water
Boiled water is good for cooking and bathing purposes only, and not for drinking because boiled or distilled water will reduce intake of calcium, phosphorus and other vital elements necessary for the maintenance and healthy life of your bones.
