They tend to live in the cockpit in front of my feet, so they are usually easy to get to, but also out of the way. Being only 5'8" I have probably close to 18 inches in front of my feet, before the bulkhead. my site

One of the cheaper filters out there, but also one of the more best water filters, is the PUR CR-6000 two stage pitcher, and this one is only a refrigerator filter, and therefore it sells for just seventeen bucks, but nevertheless, is still very effective at improving your water quality. This one is actually the most recommended water filter out of any on the market. find out more

Water filtration is the process of purifying water in order to remove unwanted solids, microorganisms, gases and chemical substances. The water is passed through a medium which retains the solids and allows only water to pass through. It is important that one gets clean, purified water to avoid waterborne diseases. There are various types of water filtration. They include; ion exchange, distillation, filtration, ultra-filtration and reverse osmosis. more

Important post. People who fall ill from waterborne diseases can't work. Women and girls who travel hours to fetch clean water for their families can't go to school or hold on to a job. Without proper sanitation, human waste pollutes waterways and wildlife habitat. Global warming and population pressures are drying up water supplies and instigating conflict over scarce resources. Expanding access to clean water and sanitation will have ripple effects throughout local economies and societies.

Mark, do they make something suitable for kayaking? I didn't see anything on their website.

Interesting post...Here in Canada, we use www.sapphire-water.ca. They have great filtration and purification systems. Sawyer water systems also sound interesting I will have to check it out. Thanks for the post.

This is interesting discussion. Reverse osmosis membranes rejects most salts, but allow pure water to pass through. The problem is, you need to exceed the osmotic pressure to allow water pass through the RO membrane. For sea water like Pacific Ocean with total dissolved solids of 33,000 mg/L, the osmotic pressure will be about 350 psi. Allow another 300 psig to overcome mechanical losses, so you are looking at 650 psi. You can generate this pressure using hand pump and may recover 10-15% water.

if it is so small, and I have no doubt it is, I wonder how the katadyn product works. When I first thought of this blogpost I did a search and found that site with the home made desalinator. very interesting.

My informal web searching shows a sodium ion to be 116 picometers in size or 0.000116 microns. Smaller, I'd bet than the H2O molecule. That's why I think mechanical filtration is out. Probably there's a better chemistry explanation.

I could totally be wrong. I found on wikipedia a listing of various items and their sizes in microns which is where I got the numbers from, and it listed 'sea salt' that may not be 'salt dissolved in water'. There are definitely two Katadyn hand operated desalination pumps. But they are very slow. http://www.katadyn.com/usen/katadyn-products/products/katadynshopconnect/katadyn-desalinators/

Thanks for the comment.

Re: mechanical filtration of salt from saltwater. I think you are mistaken. Once sodium chloride dissolves in water it becomes much smaller than its crystallized form and separates into sodium and chloride ions. These would be impossible (I think) to filter mechanically. Someone tell me if I'm wrong.
