Urban Survival - Drinking Water From a River or Retention Pond. F&J Glass Fiber Filter Paper. Particle Retention _____________________________________________________________________________ For air or gas filtration FPXM has a DOP efficiency of 98% when measured at a flow velocity of 32 liters per minute, through a 100 square centimeter area, with a particle concentration of 100 micrograms per liter of air.
DOP (dioctyl phthalate) particles used in such determinations have an average size of 0.3 microns. Liquid filtration particle retention values are highly dependent of numerous factors which affect a depth filter's ability to capture and hold particulates. These factors include the physical shape of the particles, viscosity of the solution, flow velocity and others. Although gauging particle retention values for liquid filtration are not as definitive as for air filtration, it is estimated that FPXM retains particles in the 1 to 2 micron range with very high efficiency.

Introduction Solar Still Background | Still Operation Still Water Production | Distillation Purification Capabilities The basic principles of solar water distillation are simple yet effective, as distillation replicates the way nature makes rain.
The sun's energy heats water to the point of evaporation. As the water evaporates, water vapor rises, condensing on the glass surface for collection. This process removes impurities such as salts and heavy metals as well as eliminates microbiological organisms. The distilled water from a SolAqua still does not acquire the "flat" taste of commercially distilled water since the water is not boiled (which lowers pH). Solar distillers can be used to effectively remove many impurities ranging from salts to microorganisms and are even used to make drinking water from seawater. The SolAqua solar stills are simple and have no moving parts. Supply Fill Port: Water should be added to the still via this port. HOW TO BUILD - AND USE! - A SOLAR STILL.

Ninety years ago, mine owners in the high country of Chile were faced with the problem of providing drinking water for their workers. The only available supply was unfit to drink, and so a means of purifying the liquid had to be found. Amazingly, the solution was a sun-operated distilling plant in which a large area of glassed-over wooden frames evaporated the contaminated water, recondensed it, and thus produced as much as 6,000 gallons of fresh water in a day!
This solar still used no fuel or power except that from the sun's rays and was thus able to provide pure water at a cost unmatched by any other means of distillation. Not until World War II were solar stills used again except by experimenters. Since that time Dr. The principle of the solar still is a simple one, and is observed on a grand scale in nature.
