Water Filtration Systems
Water pollutants have huge impacts on the entire living systems including terrestrial, aquatic, and aerial flora and fauna. Newly emerging micro/nano-pollutants, increasing global warming, and consequent climate changes are posing major threats to the fresh water availability.
They increase the salinity level of both land and sea water, and thus decrease the availability of existing fresh water for household, agriculture and industry.
Nonpolar carbon nanotubes (CNTs) attract polar H2O molecules and reject salts and pollutants. Low energy consumption, anti-fouling, and self-cleaning functions made CNT membranes the best choice for the job.
Summary of filtration systems:
what they do and don’t do:
- Activated Carbon Filters –
- Do: absorb organic contaminants that cause bad taste and odor; some models remove chlorination byproducts; some models remove cleaning solvents and pesticides.
- Don’t: remove metals such as lead and copper; remove nitrate, bacteria or dissolved minerals.
- Ion Exchange Units –
- Do: remove minerals, particularly calcium and magnesium that make water “hard”; remove fluorides; some models remove radium and barium.
- Don’t: soften water if it has oxidized iron or iron bacteria, which clogs the system when the ion-exchange resin becomes coated.
- Reverse Osmosis Units –
- Do: remove nitrates, sodium, other dissolved inorganic and organic compounds; remove foul tastes, smells or colors; possibly reduce the level of some pesticides, dioxins and chloroform and petrochemicals.
- Don’t: remove all inorganic and organic contaminants.
- Distillation Units –
- Do: remove nitrates, bacteria, sodium, hardness, dissolved solids, most organic compounds, heavy metals, and radionuclides; kill bacteria.
- Don’t: remove some volatile organ contaminants, certain pesticides and volatile solvents; stop bacteria from recolonizing on the cooling coils during inactive periods.
Berkey Water Filter
Berkey water filters provide the ultimate in water bourne contamination removal and is used worldwide for water filters used in clean or hostile filtration environments, w/o using chemicals or complicated processes.
The Berkey water filter system is a purifier. The portable Berkey can be used to filter non-potable or unhealthy water in situations where electricity and pressure are not there.
For everyday water from your faucet or for challenging environments like wells, rivers and lakes, Berkey water costs just 0.4 $ cents per liter to produce. The cleanable Black replacement cartridge provides an economical, reliable and powerful long term solution to poor water quality issues.
The Berkey Water Filter System is Revolutionary
Berkey water filters remove viruses to purification standards, pathogenic bacteria, cysts and parasites to non detectable levels, as well as harmful or unwanted chemicals to below detectable levels. Until publication of our tests the word non detectable was seldom used to describe a water filter to remove harmful pollutants.
The filters in the Berkey added the ability to reduce toxic heavy metals such as lead and mercury without removing the beneficial and nutritional minerals needed to support a healthy body and mind.
Compare the Berkey Water Filter to Brita, Aquasana, Pur, Katadyn or bottled water and see for yourself.
