Use a commercial water filter. A commercial water filter is the easiest and most effective way to filter sediment, pathogens, metals, and other pollutants from water. These filters contain special materials like charcoal, carbon, ceramic, sand, and cloth that are specially designed to filter out dangerous pollutants.[7] There are many different types of filters you can use, including:
According to a 2007 World Health Organization (WHO) report, 1.1 billion people lack access to an improved drinking water supply; 88% of the 4 billion annual cases of diarrheal disease are attributed to unsafe water and inadequate sanitation and hygiene, while 1.8 million people die from diarrheal disease each year. The WHO estimates that 94% of these diarrheal disease cases are preventable through modifications to the environment, including access to safe water.[1] Simple techniques for treating water at home, such as chlorination, filters, and solar disinfection, and for storing it in safe containers could save a huge number of lives each year.[2] Reducing deaths from waterborne diseases is a major public health goal in developing countries.

Distillation involves boiling the water to produce water vapour. The vapour contacts a cool surface where it condenses as a liquid. Because the solutes are not normally vaporised, they remain in the boiling solution. Even distillation does not completely purify water, because of contaminants with similar boiling points and droplets of unvapourised liquid carried with the steam. However, 99.9% pure water can be obtained by distillation.

Filters have to be changed after every 6-12 months and RO-Membrane demands to change after every 2-3 years. The maintenance depends on the source of your water. If your water is more contaminated you may need to change it more than once every 6-12 months. The best part is transparent housing that helps you to identify the time when filters need to be changed.
Use water purification and disinfection tablets. Water purification tablets are made of either chlorine dioxide or iodine and kill bacteria and viruses in water. To use these tablets, fill a pitcher or jar with water and add enough tablets to treat the water. One tablet typically treats 1 quart (1 L) of water. These tablets generally need anywhere from 30 minutes to four hours to work.[4]
DO: Avoid shark-infested waters, unless you are Andy Casagrande. As for bears, always carry repellent pepper spray when hiking; it can stop a charging bear from as much as 30 feet away. To reduce the risk of an attack, give bears a chance to get out of your way. "Try to stay in the open," says Larry Aumiller, manager of Alaska's McNeil River State Game Sanctuary. "If you have to move through thick brush, make noise by clapping and shouting."
The desalinated water purity is a function of the feed water salinity, membrane selection and recovery ratio. To achieve higher purity a second pass can be added which generally requires re-pumping. Purity expressed as total dissolved solids typically varies from 100 to 400 parts per million (ppm or mg/litre)on a seawater feed. A level of 500 ppm is generally accepted as the upper limit for drinking water, while the US Food and Drug Administration classifies mineral water as water containing at least 250 ppm.

Formally, reverse osmosis is the process of forcing a solvent from a region of high solute concentration through a semipermeable membrane to a region of low-solute concentration by applying a pressure in excess of the osmotic pressure. The largest and most important application of reverse osmosis is the separation of pure water from seawater and brackish waters; seawater or brackish water is pressurized against one surface of the membrane, causing transport of salt-depleted water across the membrane and emergence of potable drinking water from the low-pressure side.
These tablets essentially use chlorination as their method of purification. Sodium chlorite generate chlorine dioxide giving it the ability to treat water. Chlorination, as most know, is a common method of disinfecting water, and is commonly used by municipalities world-wide for this purpose. Chlorine destroys bacteria by destroying the cell walls of the bacterium/virus, killing the organism. Fortunately, when we drink chlorinated water, our digestive system quickly neutralizes the chlorine. So chlorine concentrations along the gastrointestinal tract are, in all likelihood, too low to cause damage. The tablets are wrapped in a metallic foil which makes it easy to store and there are no concerns of a glass bottle breaking. This is one of our favorite items to carry as a backup to our water filtration system.
Radium Removal: Some groundwater sources contain radium, a radioactive chemical element. Typical sources include many groundwater sources north of the Illinois River in Illinois, United States of America. Radium can be removed by ion exchange, or by water conditioning. The back flush or sludge that is produced is, however, a low-level radioactive waste.
When the water processes, the basic filtration process eliminates all the minerals out of the water. And you have to drink the tasteless and acidic water. But it is not a case with this Osmosis water filter. Home Master TMAFC-ERP has an extra stage of remineralization. In this stage, all the beneficial minerals replenish into the purified water to improve the taste.
Sea-water reverse-osmosis (SWRO) desalination, a membrane process, has been commercially used since the early 1970s. Its first practical use was demonstrated by Sidney Loeb from University of California at Los Angeles in Coalinga, California, and Srinivasa Sourirajan of National Research Council, Canada. Because no heating or phase changes are needed, energy requirements are low, around 3 kWh/m3, in comparison to other processes of desalination, but are still much higher than those required for other forms of water supply, including reverse osmosis treatment of wastewater, at 0.1 to 1 kWh/m3. Up to 50% of the seawater input can be recovered as fresh water, though lower recoveries may reduce membrane fouling and energy consumption.
If the right equipment is available distillation is another way to ensure removal of bacteria and viruses. This is one method that will allow us to use salt water for drinking. Note: If you own a boat and use it for off shore trips a desalinator such as the Katadyn Survivor series would be a prudent purchase. The Katadyn Survivor 40E can be operated manually or using 12/24 V DC power. We will cover makeshift ways of distillation in future articles.
The first documented use of sand filters to purify the water supply dates to 1804, when the owner of a bleachery in Paisley, Scotland, John Gibb, installed an experimental filter, selling his unwanted surplus to the public.[37] This method was refined in the following two decades by engineers working for private water companies, and it culminated in the first treated public water supply in the world, installed by engineer James Simpson for the Chelsea Waterworks Company in London in 1829.[38] This installation provided filtered water for every resident of the area, and the network design was widely copied throughout the United Kingdom in the ensuing decades.
The practice of water treatment soon became mainstream and common, and the virtues of the system were made starkly apparent after the investigations of the physician John Snow during the 1854 Broad Street cholera outbreak. Snow was sceptical of the then-dominant miasma theory that stated that diseases were caused by noxious "bad airs". Although the germ theory of disease had not yet been developed, Snow's observations led him to discount the prevailing theory. His 1855 essay On the Mode of Communication of Cholera conclusively demonstrated the role of the water supply in spreading the cholera epidemic in Soho,[39][40] with the use of a dot distribution map and statistical proof to illustrate the connection between the quality of the water source and cholera cases. His data convinced the local council to disable the water pump, which promptly ended the outbreak.
Different RO water filter systems handle a different number of purified gallons in a day. Normally this capacity goes from 50 to 150 Gallons per day and so on. You must identify the amount of water your family needs in a day. For Small families, reverse osmosis with 50 Gallons per day capacity is suggested while for larger families, Whole house Ro system with minimum 75-100 GPD is suggested.
I love this new ro system, I've never installed one of these before but luckily the dvd walked me through it step by step. With the Ppm meter they gave me I tested my water for the first time before and after. My ppm went from 275 to 8. I’m very pleased so far. Easy to install and I'm loving it ! Thank you so much for providing a great quality product with a simple set up for great tasting water :)
