The ceramic water filter cartridge
It seems like natural disasters are becoming a lot more regular and more devastating. Just in the last few years the number of major earthquakes, tsunamis, flooding, tornadoes, and droughts has been astounding. The news on any given week is filled with pictures of debris strewn neighborhoods, displaced people, and desperate crowds mobbing the relief trucks handing out food and water. While our modern technology has made life a lot easier for us, the downside is that we are a lot more depends 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 forms 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 for bottlenecks 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. The silver keeps bacteria from growing on the exterior of the shell, and the activated charcoal adsorbs chemicals that are present in the water. An outer pre-filter can also be attached to these filters to strain out larger particulates, if the source water is coming from natural lakes or streams.
Ceramic filters have been used by NGOs in third world countries very effectively for many years. They can use just about any freshwater source as the input such as Ponds 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 to 4000 gallons (6 to 8 months under regular, gravity-fed usage); the lifespan is basically limited by the activated charcoal in the filter. If the water being filtered is very dirty it is possible for the filter to become clogged, however the filters can be restored by scrubbing them gently with a non-soap abrasive pad. Before being used, the shelf life of the cartridges is almost indefinite if the cartridges are kept in a container that minimizes air circulation.
In conclusion the Ceramic 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
