How Safe Is The Water You Drink?

ImageThere is no life without water however most water in its rare state is not fit for drinking. It contains numerous contaminants, which can be dangerous to human health. One of the ways to get water into a potable state is by using a water purifier device.

Untreated water can contain various contaminants including bacteria, algae, fungi, minerals, man-made chemical pollutants and viruses that cannot be seen with the naked eye. A water purifier is very beneficial for healthy daily and survival living.

The reason why you need a water purification system is to kill harmful dangerous bacterial and viral diseases organisms and to filtrate out the contaminants to make your water potable for drinking.

Some common techniques used to purify water include boiling, carbon filtering, distilling, reverse osmosis, ion exchange, electrode ionization and plumbo-solvency reduction.

In future posting I plan to write about the different methods of purifying water in more detail.  I will also write about obtaining water in different environments, product reviews, DIY projects, carrying and long term storage.

Until than understand that:

  • Carbon filtering: water is passed through activated charcoal to remove contaminants. There are two types of carbon filtering systems granular charcoal filtering and sub-micron solid block carbon filtering.
  • Electrodeionization: It includes passing the water through a positive electrode and a negative electrode. Water is typically passed through a reverse osmosis unit first to remove nonionic organic contaminants.
  • Plumbo-solvency reduction: In areas with naturally acidic water of low conductivity (i.e. surface rainfall in upland mountains of igneous rocks), the water is capable of dissolving lead from any lead pipes that it is carried in. The addition of small quantities of phosphate ion and increasing the pH slightly both assist in greatly reducing plumbo-solvency by creating insoluble lead salts on the inner surfaces of the pipes.
  • Reverse osmosis: The reverse osmosis water system is the technique in which mechanical pressure is applied to an impure solution to force pure water through a semi-permeable membrane. The process is ideally the most thorough method of large-scale water purification
