Might be something for a thread of its own, if you can provide a few representative sample pages. I've had some luck reducing color depth to 1bit for text areas. Doesn't do much for JPEG but helps PNG a lot. If those columns always were in the same places you could slice it up so every column is a page on its own, making each page a smaller image and easier to handle for the reader. There's also k2pdfopt which can reflow scanned text but I'm not sure if it handles columns.

But in the end aside from OCR or somehow obtaining a digital copy of the original source, there's only so much you can do with scans...
