Are you familiar with Biology? Do you love Science? Do you know the difference between Prokaryotic and Eukaryotic cells?
If you answered yes to any of these questions, this is the place for you!
Here you can post random scientific facts, ask questions you're dieing to know, even discuss scientific issues, and chat regularly with your peers.

It has something to do with osmosis, I know that much. At least I'm pretty sure it has to do with it. sweatdrop Right now, something I wonder about is the use of reverse-osmosis for water purification.

Osmolarity is a measure of the osmotic pressure exerted by a solution across a perfect semi-permeable membrane (one which allows free passage of water and completely prevents movement of solute) compared to pure water.
I'm a major science geek. ^_^ I study nuclear chemistry, alchemy, chemistry, biology, nuclear physics, physics, whatever...and the scary part is, that's just a tiny part of who I am. ninja

What is it that you would like to know, perhaps one of can help you understand reverse-osmosis better.

What is it that you would like to know, perhaps one of can help you understand reverse-osmosis better. I'm wondering how exactly it works. I understand osmosis is the moving of water into a cell, so reverse osmosis would be removing it from the cell? How exactly would it help water purification?

Azlema How familiar are you with Biology? I took Biology Honors last year biggrin It's pretty damn cool, in my opinion. Quote: Do you know the difference between Prokaryotic and Eukaryotic cells? Ooh ooh! I learned this a long time ago! Eeeh prokaryotic cells don't have a nucleus and eukaryotic cells do? Or am I mixed up ^^;.... Chemistry is quite the fun class biggrin

Reverse osmosis, also known as hyperfiltration, is the finest filtration known. This process will allow the removal of particles as small as ions from a solution. Reverse osmosis is used to purify water and remove salts and other impurities in order to improve the color, taste or properties of the fluid.

Umm... Quote: How familiar are you with Biology? Isn't really a yes or no question. sweatdrop Because. Quote: How familiar are you with Biology? Yes. Just doesn't make sence.

I understand osmosis is the moving of water into a cell, so reverse osmosis would be removing it from the cell? How exactly would it help water purification? Reverse osmosis uses a membrane that is semi-permeable, allowing the fluid that is being purified to pass through it, while rejecting the contaminants that remain. Most reverse osmosis technology uses a process known as crossflow to allow the membrane to continually clean itself. As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected species away from the membrane. The process of reverse osmosis requires a driving force to push the fluid through the membrane, and the most common force is pressure from a pump. The higher the pressure, the larger the driving force. As the concentration of the fluid being rejected increases, the driving force required to continue concentrating the fluid increases.

All For Penguins Umm... Quote: How familiar are you with Biology? Isn't really a yes or no question. sweatdrop Oops. Haha, I got so carried away, I didn't even realize that you couldn't answer 'yes' or 'no' to it. Forgive my mistake.
