Cleaning Water |
Nanofiltration97% of the earth’s water is salt water! Is there a way to desalinate this water and help turn it into clean "climate resilient" water for global use? Nanofiltration is an inexpensive technique that prepares climate resilient, usable, potable water! Cost is as low as 30-50 cents per 10,000 gallons! Highly effective in transforming sea water, waste, grey, other water into potable water. Tiny one-celled organisms eat contaminants present in water (this is called “bioremediation”). Water filtered through porous membranes, like a “sieve”. Holes in “sieve” are microscopic and highly effective! They can only be seen on “nanoscale”. Result is CLEAN, potable water. Australia is actually planning to use a type of nanofiltration system to make potable water from pig-sewage waste water! Nanofiltration: A great option for world-wide water future. Hope to be able to very cheaply provide nanofiltration systems for individuals and communities well within decade. Nanofiltration units, both smaller and whole-house or commercial grade, are readily available for purchase. |
Cleaning water is a very complex process! Environmental scientists and engineers are experimenting with creating nanomembranes that are low cost yet very effective for filtering water and making it drinkable. Nanofiltration offers a way to make even the most undrinkable water safe to drink.
Nanomembranes can be uniquely designed with specialized layers that are placed to perform highly specific jobs such as desalinating salt (ocean water)! Nanofiltration systems can be utilized to effectively clean even the world’s most polluted water systems. Membrane filter technology traps tiny particles and contaminants that won’t fit through the membrane, and leaves behind clean, potable water! Scientists are hopeful that inventions like nanofiltration may help solve the global water crisis. Many types of nanofiltration systems are available today. Residential “sink” to “whole house” models run from about $500 to $5000, depending on level of filtration. Commercial systems (2000 gallon to 10,000 +) run from $10,000 to much more. You can get a nanofiltration system that filters out just a few harmful elements, or a system that filters everything, like turning sewer water into potable water! | |
