Post filtration of an alumina filter would get any remaining solids out of the water, especially any as large as would be present from the filter media itself. There are .1 micron filters on the market that can even filter out virus particles.

A very fine powder could be transported by water as a slurry, suspension, or colloid though.

Is it possible for the waste byproduct of aluminium processing plants added to mains water supply to contain any aluminium oxide - at all?

It has a wide range of uses, from grinding abrasive, plastic filler, electrical insulator (like for spark plugs), filter medium, paint filler/pigment, catalyst, and gemstones, such as rubies and sapphires.
