Water is one of the basic needs of all living beings. Each of us consists of about 65% water and humans need at least two litres of it a day. In many regions of the world, surface and ground water are the main sources of drinking water. These water sources are often polluted by urban and industrial chemicals. Water treatment plants reduce the concentration of harmful chemicals to a safe level, while disinfection removes microbiological hazards. But when the water is supplied to users via distribution networks, additional safety problems arise.
When the distance between treatment plants and the water user is great, secondary water pollution becomes important because micro-organisms reproduce within the supply system. And because of the presence of disinfectant agents, the various harmful byproducts accumulate in treated water, many of them poisonous.
At present, this global problem is resolved by producing bottled water for cooking and drinking. The installation of different adsorption-filtering and osmotic systems at the points of use is also popular.
Now there is a more economical solution. Secondary polluted water contains organic matter whose molecules exhibit surface-active properties. These molecules can be adsorbed (collected) at the air-water interface. Their surface concentration is 100-1,000 times higher than in the bulk water phase. We have used this fact to develop the Bubble-Film Extraction system for conditioning secondary polluted water. The principle of BFE is simple: air bubbles are fed into contaminated water and dissolved surface-active matter is absorbed onto the surface of the bubbles. The flow of air bubbles delivers the surface-active molecules to the water surface, which becomes covered by a thin layer of impurities.
Why do you need to purify water?
One in six people in the world have no access to safe drinking water.
In large cities the water quality is deteriorated in distribution pipeworks to dangerous levels.
It is absolutely necessary to additionally purify tap water before its consumption.
How can you effectively purify water?
Now you can obtain safe, high quality drinking water at a much lesser cost with bubble-film extraction water-purifying systems «Aquilegya».
«Aquilegya» systems have no cartridges to be replaced.
«Aquilegya» systems provide stable purification efficiency that does not deteriorate throughout the system operation.
«Aquilegya» systems effectively purify water from different sources and do not affect useful mineral composition of water.
