Portable Water Purification
The water provided by the city can be dirty and probably has a sufficient amount of toxins substances that will cause a severe damage to anyone who will drink it. Portable Water Purification devices which use field water disinfection system and point-of-use (POU) water treatment are self-contained division that can be utilized by military personnel, survivalists, recreational devotees and others who get drinking water from untreated, unknown water sources like rivers, lakes, well, etc. These personnel devices aim to make contaminant water potable, clean, safe and secure for drinking purposes.
There are several commercials that introduce portable drinking water systems or chemical preservatives in remote areas. These devices are not only promoted for remote areas but these devices can also be used to treat and provide secure municipal water for visual purposes by reducing bad taste, chlorine, mercury, lead and water odors.
And because water is prone to having unwanted micro-organisms and to being contaminated, it makes sense why water purifiers are made and how they work. It is also important to learn how to utilize portable water purifiers. A large quantity of people use portable water purifier for camping and outdoor adventures. There are techniques used to make sure the water you are drinking is safe and potable and clean:
Boiling: Boiling is one of the best and inexpensive methods to use to make clean and filter the water you are drinking. Boiling water will help you kill bacteria and harmful microorganisms such as Cryptosporidium parvum, amoeba cyst and giardia lamblia which are normally found in lakes and rivers. A combination of boiling at standard pressure plus filtering with triggered charcoal can counter balance the pollutants and pathogens.
Filtration: Filtration elements do an excellent job in removing germs, bacteria and fungi pollutants from drinking water. Filtration removes unwanted contaminants down to the smallest possible sizes between the ranges of 0.2 to 0.3 micrometers.
While the filtration elements may do an excellent job of removing bacteria and fungi contaminants from drinking water when new, the elements themselves can become colonization sites. In recent years, some filters have been enhanced by bonding silver metal nano-particles to the ceramic element and/or to the activated charcoal to suppress growth of pathogens.
Ultra violet purification: Ultraviolet (UV) light induces the formation of covalent linkages on DNA and thereby prevents microbes from reproducing. Without reproduction, the microbes become far less dangerous.
In SODIS (Solar Water Disinfection), microbes are destroyed by temperature and UVA radiation provided by the Sun. Water is placed in a transparent plastic bottle, which is oxygenated by shaking. It is placed for six hours in full sun, which raises the temperature and gives an extended dose of solar radiation, killing some microbes that may be present. The combination of the two provides a simple method of disinfection for tropical developing countries.
The solar still relies on sunlight to warm and evaporate the water to be purified. In an extreme survival situation the solar can still be used to prepare safe drinking water from usually unsuitable sources, such as one’s own urine.
