it is urgent pls answer now?

Question

can anyone tell me the traditional methods of water purification. and their drawbacks. or tell me the place where i can find information about it.

can anyone tell me the traditional ways of purifying water other than boiling and thei side effects or drawbacks.

Answer 1

Boil it, but you want other traditional means? Leaving it in the sun will help, due to UV, especially in a shallow containers.

Fermenting works. The yeast get churning along and out compete most everything else. Think of the middle ages or even early industrial England. Either you were rich enough to drink only tea (boiled) and beer (fermented) or you got cholera, dysentery, etc.

For other than infectious issues? Inuit ("Eskimos") traditionally harvest multi-year sea ice. Going through several summers and winters without melting, "zone-refines" the saline ice to drinkable water.

Settling would have been used for tens of thousands of years to let silt and mud drop out of turbid water. Since bacteria mostly are attached to those particles, it would also be less infectious. One could, in an aboriginal setting add wood ash (alkaline) to "flocculate" (coagulate) those suspended solids more quickly and completely.

Hope that helps,

Don't know how high level you want this to be but this is an abstract of a microbiology article


An assessment of existing common traditional methods of water purification

Abstract
Classical water purification methods include boiling, filtration, irradiation and the use of chemicals while traditional water purification methods in use are boiling, filtration, sedimentation, long storage and solar radiation. Waterborne diseases are m ore common in the rural communities where potable water supply coverage is usually low. Therefore, this study was designed to assess and modify existing water purification methods in use in the rural communities so as to encourage their regular use.
Water samples collected from various sources serving six rural communities in Agege, Epe and Ikorodu Local Government areas of Lagos State were purified using each of the traditional methods. Viable counts were carried out on each of the water samples before and after the purification process. Water samples contamination with known pathogens were also included in the test.
The boiling method was the most efficient giving 100% decontamination after three minutes of continuous boiling. The solar method gave varying degrees of decontamination of the water samples (42-100%) depending on the turbidity of the water and the type of container used for the test. The long storage method and the cloth filtration methods decontaminated the water by (0.6-4.2%) and 41% respectively.
The solar water purification method should be encouraged. Turbid water samples should be cloth filtered prior to exposure to the sun for maximum efficiency.

Answer 3

there's a whack of them:

Boiling water is the most common, but it doesn't take out any impurities. For that we have filters.

Charcoal Water Filters
Reverse Osmosis
Water Distillers
Ionized Water Filters
Ultraviolet Water Filters
Back Flush
PiWater Filter

But filters can't catch everything, they sometimes let through virii, spores and small bacteria through.

Best deal in town is to filter first, boil later. That way you guarantee no crud or bugs in your water.

Answer 4

THERE IS AN ITEM CALLED THE "C.I.A STRAW"developed for use overseas were the amoebic dysentery concontent of water can be "of the scale"!!!i experienced "first-hand" in big sur...how bad that can be!!!i contacted "acute amoebic dysentery and peritonitis drinking the water,that was "crystal-clear"and to all appearances "harmless";even though we had boiled the water for weeks previously!!!ALTHOUGH the C.I.A. are a pack of "nasty rascals"(quote from an ex-C.I.A. member)this is one thing they have actually done to "benefit mankind"which would prove INVALUABLE WORLDWIDE!!!CARBON-FILTERING WOULD BE ANOTHER "PRIMITIVE CONDITIONS METHOD as certain organic and non-organics would chemically bond with carbon and be excluded!!!!!stone filters like the old "gasoline filters"resevoirs might work also!!

Answer 5

Boiling. Distilling. Evaporate it, and collect the water when it condenses again. Filters. Tablets. Much more.

Answer 6

boil water for 30 mins

Answer 7

boil it?
