Raw water TOC removal
Raw water TOC removal
(OP)
Right now we are having problems with TOC's in our demin train. The water comes from a river and is treated with a coagulant and a floculent on the way to our retention pond. We use chlorine before we send it to the plant about 10 miles away.
The problem we are having is that the TOC's are plugging up our multi media filters (even to the point we had small swimming things for awhile).
What are some good companies to look at to assist us with this problem.

If you can tell me roughly where you are located, I can probably give you some contacts.

I have come across the problem of high TOC and it was solved by installing a RO downstream of DM plant to further polish part of the Demin water. This RO polished water is used only for boiler make-up which is relatively a small quantity (approx. 7 to 10 m3/hr). If you are interested further pl leave your e-mail ID here.

I have seen this water sucessfully treated with a two stage filtration process. Starting at your retention pond. The first stage filter (working filter) should be a direct filtration process using a polymer added inline before the first stage filter(s) operating at 3 gpm/SF. The second stage filter(s) should be polishing filters operating at 6 gpm/SF.
The filters should produce an extremely low SDI water that will allow the use of an RO process. You probably should have an RO process installed in front of your DI units anyway to reduce the cost of treating the water.
Siemens Water or Graver should be able to help you.

There is a solution. But first, you have to get professional help. Equipment manufacturers are in business to sell their equipment. You really need an unbiased consultant who is able to consider more than just one or two pieces of the puzzle.
