Cooling Water Screen
Cooling Water Screen
(OP)
I am looking at ways of improving the current method of screening cooling water. We are having problems with fouling of heat exchangers due to the make-up water.
I was wondering if anyone could let me know what they have seen, used or can recommend. Really, any help would be incredibly useful.
Thanks in advance.

perhaps looking into the source of fouling and then corrective action can then be taken.
good luck!

Most of the problems are resulting from debris in the make-up water taken from a river. It is finding its way through the pumps into the exchangers.
We currently have two screens in series before the pumps, but materials are still passing through when they are lifted out for cleaning.
I'm looking into rotating screens and other self cleaning types which hopefully will redurce operator time input and maintenance costs. I was wondering if anyone knew of specific designs/models that they've seen or have used that work well, are cost effective, low maintenance etc.
pmover, it's for an Ethylene plant so high CW purity is not essential, just need the bits to be removed. Total cooling water flow is ~35000 m3/h. There's all the usual chemical treatment of CW (acids, Chlorine...)

It has been pretty much maintenance free.
We were going to open this thing up earloer this summer, when we had a big problem with biosolids in our cooling water system. we were going to inspect it and replace some parts, kind of on a preventative basis. However, we fixed the biosolids problem and didn't get around to it.
