We all know that dehydration can be dangerous, leading to dizziness, seizures, and death, but drinking too much water can be just as bad. In 2002, 28-year-old runner Cynthia Lucero collapsed midway through the Boston Marathon. Rushed to a hospital, she fell into a coma and died. In the aftermath it emerged that she had drunk large amounts along the run. The excess liquid in her system induced a syndrome called exercise-associated hyponatremia (EAH), in which an imbalance in the body's sodium levels creates a dangerous swelling of the brain.
Pre – Membrane filters: The tap water is pollutant with harmful molecules that even we can’t notice from our naked eyes. Pre-membrane filters remove those materials that may damage the RO Membrane and cause a great loss. The solids like dust, rust gets eliminated from the water. This makes the water ready to filter more. Mostly RO water filtration systems have 3 pre-filters.
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light.
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.

There are multiple built in filters water bottles choices. Vestergaard's Lifestraw Go and Sawyers Personal Water Bottle are two examples. The Lifestraw Go filters specs say it will filter up to 1,000 liters (264 gallons) of water down to particulate matter larger than 0.2 microns Source Sawyer's Personal Water bottle absolute hollow fiber membrane inline filter down to 0.1 micron.

Each branch of the United States armed forces has their own series of reverse osmosis water purification unit models, but they are all similar. The water is pumped from its raw source into the reverse osmosis water purification unit module, where it is treated with a polymer to initiate coagulation. Next, it is run through a multi-media filter where it undergoes primary treatment by removing turbidity. It is then pumped through a cartridge filter which is usually spiral-wound cotton. This process clarifies the water of any particles larger than 5 µm and eliminates almost all turbidity.
Accidental shootings are an obvious hazard of hunting, but guess what's just as bad: trees. "A tree stand hung 20 feet in the air should be treated like a loaded gun, because it is every bit as dangerous," says Marilyn Bentz, executive director of the National Bow hunter Educational Foundation. Most tree-stand accidents occur while a hunter is climbing, she says.
Use sedimentation. When you don’t have access to anything that you can use to filter the water, you can remove large particulate from water by letting it settle. Collect the water in a bowl or jar. Leave the water to settle for one to two hours. During this time, heavier particles will sink to the bottom, and lighter material will float to the top.[3]
Iodine tastes just like it smells, fortunately, this is a pretty weak solution, so the taste is not overpowering; it is only slightly worse than city water. The advantages of iodine crystals, is that, one container can treat somewhere in the neighborhood of 10,000 gallons. As well as the fact that, it prepares the water relatively fast. The disadvantage is, as mentioned above, that it is harmful in the long term.

In 1977 Cape Coral, Florida became the first municipality in the United States to use the RO process on a large scale with an initial operating capacity of 11.35 million liters (3 million US gal) per day. By 1985, due to the rapid growth in population of Cape Coral, the city had the largest low-pressure reverse-osmosis plant in the world, capable of producing 56.8 million liters (15 million US gal) per day (MGD).[7]


Filter out pathogens with pine trees. Certain plants are effective at removing pathogens from water, and pine trees are among the best. To remove viruses and bacteria from your water, remove a small branch from a pine tree. Strip the bark from the stick and place the bare stick into a bucket. Slowly pour the water, letting it trickle onto the stick and into the bucket.[10]
There are multiple levels of filtration. As long as the water has been purified properly, filtration at this point would mostly be to make the water more attractive. Since most of us are not used to, drinking water with, leaves, algae, dirt, etcetera. So, at least a minimal amount of filtration is recommended. Since, while you can ingest/digest the aforementioned, most of us would prefer not to.
Thanks a lot to KPS for sharing such an informative article about outdoor travel survival tips. I have read your valuable page and gotten much information and now my confused has cleared. I love travel. But I have a little question that, I have a little baby but how to take care in travel time? And which foods are good for baby survival times? And which dress will be comfortable for baby in survival time? Could you please suggest me? Then I will be benefited. Anyway, I will share this article with my friends. I hope they will be benefited by this article.
Portable reverse osmosis water processors are sold for personal water purification in various locations. To work effectively, the water feeding to these units should be under some pressure (280 kPa (40 psi) or greater is the norm).[9] Portable reverse osmosis water processors can be used by people who live in rural areas without clean water, far away from the city's water pipes. Rural people filter river or ocean water themselves, as the device is easy to use (saline water may need special membranes). Some travelers on long boating, fishing, or island camping trips, or in countries where the local water supply is polluted or substandard, use reverse osmosis water processors coupled with one or more ultraviolet sterilizers.
If you are looking for the best ways of treating your water, Schultz Soft Water is your best source of advice on best water purification methods and custom solutions to your water purification needs. Reverse osmosis is the best option, whereas filtering is good for basic water tasks such as sediment and chlorine removal. Reverse osmosis covers a larger spectrum of contaminant removal.

Iodine solutions kill bacteria by upsetting the ion balance within the cell, replacing chemicals that the bacteria needs to survive with iodide ions. Iodine can also be poisonous to humans, and can be especially harmful to young children, and pregnant women. You should be careful not to use too much iodine when purifying your water, and if at all possible avoid using it as a primary purification method for extended periods of time. If you find yourself in a survival situation, for an extended period of time, you should consider setting up a still, or boiling the water if possible.
Pure water has a pH close to 7 (neither alkaline nor acidic). Sea water can have pH values that range from 7.5 to 8.4 (moderately alkaline). Fresh water can have widely ranging pH values depending on the geology of the drainage basin or aquifer and the influence of contaminant inputs (acid rain). If the water is acidic (lower than 7), lime, soda ash, or sodium hydroxide can be added to raise the pH during water purification processes. Lime addition increases the calcium ion concentration, thus raising the water hardness. For highly acidic waters, forced draft degasifiers can be an effective way to raise the pH, by stripping dissolved carbon dioxide from the water.[4] Making the water alkaline helps coagulation and flocculation processes work effectively and also helps to minimize the risk of lead being dissolved from lead pipes and from lead solder in pipe fittings. Sufficient alkalinity also reduces the corrosiveness of water to iron pipes. Acid (carbonic acid, hydrochloric acid or sulfuric acid) may be added to alkaline waters in some circumstances to lower the pH. Alkaline water (above pH 7.0) does not necessarily mean that lead or copper from the plumbing system will not be dissolved into the water. The ability of water to precipitate calcium carbonate to protect metal surfaces and reduce the likelihood of toxic metals being dissolved in water is a function of pH, mineral content, temperature, alkalinity and calcium concentration.[5]

A properly packed backpack is requisite to your comfort and safety. Incorrect weight distribution leads to muscle aches and unnecessary strain on your spine. Place heavy items – water, food, and cooking gear – in the middle of your pack, close to your body. Use medium weight items – clothing, tarps, and rain gear – to cushion the heavier items, securing them, so the weight does not shift while you are hiking. Pack your sleeping bag in the bottom of your backpack or tie to the bottom. Store items that you are likely to need more frequently in the side and outer pockets – compass and map, sunglasses, toilet tissue and trowel, sunscreen, bug repellent, pocketknife, flashlight, snacks, and a small towel.
It’s extremely important to confirm your water has been purified or treated before drinking. If your water is contaminated and you don’t have bottled water, there are various water purification methods that are used today, and each method has its merits and demerits. Filtering is good for basic water tasks such as sediment and chlorine removal, but in the long run reverse osmosis is the best option. At Schultz Soft Water we focus on reverse osmosis units because they require a lot less energy and time required to make water versus distillation.
