Scientists have found a way to make clean drinking water using algae.

Teams in Bangladesh and Sweden harvested the organism locally and extracted what they call cellulose nano-fibers to create paper filters.

The pores are small enough to collect bacteria and viruses from dirty water.

And they use the particular algae called Pithaphora because it grows in huge volumes in Bangladesh, and can be found in almost all freshwater habitats there.

Dr. Mohammah Almujaddade Alfasane at Dhaka University said the process worked just as they expected.

DR. Mohammah Almujaddade Alfasane, a Professor of the Department of Botany, said, "This pithophora was collected from different habitats of Bangladesh and cultured in the botanical garden, department of Botany university of Dhaka. Then we processed it and sent it to Sweden. This nanofilter is capable of removing all types of bacteria and viruses, which are pathogenic, from contaminated waters."

It won't eradicate the threat of disease just yet of course.

For the moment, the system only works under very particular conditions.

But eventually the new filter could be cheaply produced and distributed, they say, and easily installed on public and private water sources.

Bangladesh has one of the highest population densities in the world.

But, according to water.org, four million people in the country lack access to safe drinking water.
