Can You Make A Home Made Water Purifier?
In Africa, women who do not have a clean water supply have been taught to pour water from one pitcher into another, using several layers of cloths to strain out contaminants between. This home made water purifier has been effective at eliminating a lot of water-borne disease in this poor region of the world, but you must ask whether this technique is either effective or wise when applied to a Western water system. Most home made water filters are more complex and involved than this, of course, but they still lack the controls you'll find on commercial water purifiers.
Home made water purifier instructions you'll find online are complex. They are often simple filters, but they are often more complex systems such as distillation. Still, there are some serious problems with the do-it-yourself approach to water filtration. Improperly filtered water can be a health hazard. It is worth of praise and understandable that you wish to save money by making your own filters, but you should recognize that if you do, you may spend just as much money as you otherwise would while also putting yourself and your family at risk.
One of the problems with home made water purifiers is that they don't tell you when they are saturated with contaminants; on the other hand, commercial water filters usually do. If you keep using saturated filters without knowing it, you're not only getting un-decontaminated water; you're actually dissolving some of the previously-removed contaminants and getting a double dose. Unless you're using a distilled water system, you should assume that your home made water filter needs replacing, and that means you have to figure out your own saturation period.
Even if you use a distillation system or something else that supposedly removes all the contaminants from your water, you are likely to have a problem. For one thing, distillation removes even good minerals like iron, copper, and calcium, but it does not always remove chlorine, as chlorine is naturally a gas and will evaporate - and condense - right along with the water. In addition, distilled water that is not subsequently aerated will taste flat and lifeless, and your distillation system may add its own contaminants to your newly-purified water. You really need to know what you're doing.
For those who are still planning to build a home made water purifier, make sure that your filtration system has several layers: sand or diatomaceous earth, a layer of fiber or mesh, activated carbon, another layer of mesh, and then a third layer of diatomaceous earth. These filters work best if water is put through at pressure, after being allowed to settle. Once you've filtered your water, test it by letting a glass sit for a day or so to see if anything settles in the bottom or if the water gets cloudy. You can also send out samples to biological laboratories to have a thorough test done for microbes if you do not get your water from a municipal supply. Unless you're doing something very large scale, it's likely to be cheaper and easier to buy a premade filtration system.
