The ceramic water filter cartridge
It seems that natural disasters are more frequent and more devastating. Especially in recent years the number of large earthquakes, tsunamis, floods, tornadoes, droughts, and it was amazing. The message is spread on a given day with pictures of the debris scattered neighborhoods, displaced and desperate crowds mobbing the food relief and trucks filled with water. While our modern technology has made life much easier for us, is the flip side, we are much moredepends on things "right". In other words, we are extremely vulnerable when our infrastructure in power, transport and the availability of goods is disturbed. It could happen almost anywhere with little notice.
As a risk reduction, most of us some form of insurance to protect our property and take care of medical bills, but many of us are not as willing to create an initial disaster and the need to bottlenecks that occur in the early resistance to survive periods ofRecovery. Simple steps taken in this area can avoid a lot of problems later. One element that is crucial to sustain life, but is often in short supply, drinking water is easy. Bottled water is the first thing that comes to an end and the first item in the list of humanitarian goods, such as the human body can only survive about four days without water.
A simple device for water purification was developed and tested in countries where there are no modern water infrastructure and water trafficDecimate populations of bacteria. (Hundreds of people die every day from bad water quality). The device is a ceramic water filter cartridge and is an excellent opportunity for the availability of water in emergency situations at home to ensure it.
The ceramic water filter cartridge consists of a softball size, dome-shaped shell with a small amount of silver and contains a certain amount of active carbon coated. The dish has a small opening through the pores that allow water, butare too small for bacteria. Silver remains the growth of bacteria on the outside of the shell, and the charcoal absorbs chemicals in the water. An outer prefilter, these filters can also be attached to larger particles of pollution if the source water comes from lakes or streams.
Ceramic filters are NGOs in Third World countries used very effectively for many years. You can do almost any fresh water source, such as the use of inputsPonds or streams (so they are ideal for camping and off-grid life as well as emergency situations). The filters are usually two containers, one used to contain contaminated water at the top and the second to keep the water clean filtered down.
These cartridges can be used in gravity systems with easy buckets or barrels, that does not require electricity to operate will be built. Set with a standard 5 gallon bucket filters 12-15 liters per day. Add a siphon tubeIncrease this to more than 30 liters per day.
If desired, more water can be parallel to the container as a filter (a standard 5-gallon bucket holds up to three filters) related. Another method is to accelerate the flow of the system (air pressure or water pressure) for pressure. A simple bicycle pump and a tightly closed container, flow velocity increases significantly. Taller containers can also accelerate the flow by increasing water pressure.
The cartridges last3000-4000 gallons (6 to 8 months with regular use of gravity), life is essentially limited by the activated carbon in the filter. If filtered water is very dirty, it is possible that the filter becomes clogged, however, filters can be restored by rubbing gently with a non-soap flakes. Before use, the cartridge life is almost unlimited, if the cartridge in a container that holds to minimize air circulation.
Finally, theCeramic water filter cartridge is a great way to ensure the availability of drinking water even at the worst. They provide the bacterial and chemical filtration, from virtually any source of fresh water, without an external power source or additional chemicals. You also have the advantages of small size, low cost and unlimited. With a little 'fantasy can be used in systems that provide different amounts of water can be set anywhere from a dozen to hundreds of liters perDay
