Reverse Osmosis

The Process:
Water is forced under pressure through a synthetic, semi-permeable membrane. The water that passes through the membrane goes into a storage tank (usually plastic or rubber). Most of the water goes down the drain with the contaminants that were removed.

The Effectiveness:
In theory, the membrane, because of its extremely small pore-size prevents micro-organisms and chemical contaminates from passing through the membrane. In practice, however, the contaminants build-up, clog and damage the membrane. Bacteria grow through the membrane and make holes it, so the quality of water produced by reverse osmosis degrades over time. This means that the quality of the water is not consistent, and the customer has little peace of mind.

Pure Water Brand Water Distillation Systems

The Process:
Heat is added to water, causing it to evaporate, thus leaving the contaminants behind. The steam is then captured and cooled back down into high purity distilled water. It is then stored in a stainless steel container.

The Effectiveness:
The boiling action kills bacteria and other micro-organisms, and contaminants are left behind in the boiling chamber. The effectiveness of distillation is over 99+% (99.99% removal has been achieved even on ocean water--over 35,000 P.P.M). The quality of the distilled water is not affected by the level of source water contamination, water temperature or pressure. The quality of the distilled water remains consistent over the life of the unit! Peace of mind is excellent!

Water Filters vs Water Distillation

Water is passed through a filter to remove certain contaminants. Most filters use activated carbon (carbon which has been treated by high heat in the absence of oxygen) to absorb some organic and inorganic contaminants. Adsorption occurs by the strong molecular attraction that carbon in the filter has for some of the contaminants often found in water.

The Effectiveness:
When brand new, a carbon filter will do a fairly good job of removing certain organic contaminants, but it will do very little (if anything) to remove other contaminants in the water such as biological, toxic metals or radioactive. There are a number of factors which can adversely affect their effectiveness.

• The physical barrier that a filter is can break down.
• Over all effectiveness is poor and declines sharply over time.
• Proper contact time (7-18 minutes) is crucial or even organic substances may not be removed.
• Filters can quickly clog up.
• Filters can become a breeding ground for bacteria often within 5 days or less. Inorganic contaminants are removed poorly.
• In fact the total of dissolved solids will generally increase inside the filter, sometimes significantly.
• Long term replacement costs of filters are often quite high.
• Since one has no idea how effective a filter is at any given time, peace of mind is usually low.
