Removing glue residue from discharge water

First off, many thanks for a speedy response on the forum.

And here is the next problem:

I have received an enquiry regarding a manufacturing plant that needs to treat its discharge of water which is contaminated with a glue residue. (I dont have analysis available of the glue yet).

So far, our company has installed settling tanks in an attempt to reduce the amount of glue residue discharged to waste. However, I dont see this as the most effective solution and am thinking of another method of treating the discharge. Filters have been thought of, but they would require very frequent changing and I dont feel that its the most effective method.

One idea would be to set up an SBR that could break down the glue residue. Cost is an issue (isnt it always!!) here, so if this IS the best method of controlling the discharge, how much would we be looking at for an SBR plant (or other method of treatment)

Any ideas on this would be most helpful :)

Many thanks,

Lucaz

I have no experience with removing "glue", but I concur with Jim. Some type of coag/floc and skimming process is probably the way to go.

You are correct, Lucaz, on your analyses:
-Glue probably won't settle much, it will probably act much like a colloidal suspension.
-Mantenance cost on Filters would be prohibitive.

I don't hink there is a bio. process to digest glue, but there could be. It is worth looking into, but it can't be cheaper than coag/floc.
