suggestions?

I use acrobat pro to optimize PDFs for ereader.
If both book pages were scanned onto a single PDF page I print that PDF new to file and select the page tiling option - this separates into individual pages (If the middle line is not too far out of center).
Then I run the scanned doc with (from menu "Document") Optimize Scanned PDF feature where text is de-skewed, despeckled, edge shadow removed etc.
To reduce file size on text which has been unnecessary scanned in colour mode I use the preflight option to convert colour to grey scale (file size).
Next is to crop the page margin. Sometimes each individual page manually.
Then the OCR - with clearscan selected text becomes searchable and filesize can collapse dramatically.
Advanced tool "Accessibility" and tagging the document helps with reflowing - however mixed text and pictures may lead to jumbling the sequence of the document in reflow reading.
Finally I optimize further with the advanced tool "PDF optimizer" for fast web view feature.
I am quite anal with file sizes. The smaller the size the less processor power is needed = battery and response times.
The whole process can be very exhausting and time consuming - result is generally shocking good.
I just finished a book which was really lousy scanned and difficult to read - even on computer - took me something like 10 hours. But is is a joy now to read on my 950 - fully searchable and re-flowable.
