Disaster relief water filtration

Ok Wallies I need help here. This is not a heating question.



I have a friend that is working in Japan to help with disaster relief. He is trying to filter water out of a raging muddy river to supply drinking water. He is using a large R.O. system, but they have had so much rain lately that it is stirring up mud and rocks and plugging the RO filters.



I suggested he use a junk pump first with an in line filter in the hose. Maybe even some of centrifuge and then in to the RO system.

Thanks in advance

Check with Grundfos...

I'm fairly certain they have a portable water treatment system that they used in Haiti.



If worse come to worse, you could use a centrifugal sand filter, with a bag type of pre filter before it goes to the RO system.

Kudos to him for being there to help. Tough job under the circumstances.

Another resource....

The Presbyterian Church USA is a major first responder  when it comes to water filtration and supply in catatrophic situations.  I suspect they probably have come across just about any problem, so your friend may want to contact them.  They are probably right there in Japan with them or at pcusa.org.
