Deairing water
Deairing water
(OP)
In geotechnical testing labs it is common for water used ing testing to be deaired. For example, triaxial testing and permeability testing. There are many deairing units available for sale but have relatively small capacities. I am considering building one for our new lab and am interested in any ideas or experiences people have with deairing tanks.

The only drawback? You can't visually inspect it for algae, etc.
Plexiglas will also work, but will cost a great deal more. I'd avoid a metal container.
A cheap, temporary de-airing tank? Try a 5 gallon drinking water bottle, rubber stopper, tubing and vacuum grease -

This is very useful information. I would like to see the pics/plans you have and am going to consider the Liquicel membrane as well. It sounds like it might be within our budget. I am going to be gathering information for the next month or so and start building or purchasing a device by the end of the year.
Is there a URL you can post where I can view the pictures?

We used to use a large water bottle as Focht3 pointed out. It worked fine.
