Filtration, Am I Crazy?

[donlite]

I would like any input on building a Fluidized bed filters. Is it possible to use say 4" diameter plastic acrylic tubes (I have about 20 left over tubes from
one of my companies left over job parts) and set up a series (2,3 or 4) cylinders each having there own use eg. first one mechanical filtration (3 or 4
levels of filter pads, then a fluidized bed sand filter, then say charcoal or any other chemical filtering media. My company has a cnc router and can easily
produce plastic end caps etc. and we use a UV curing glue that sets in seconds
and does not distort the plastic. Thanks for taking the time to read this. I would also like to look at making a free site to view the steps for anyone to do DIY.
