Um, beer and urine doesn't have relevant particulate size (but for a few
contaminants) which determine the taste. Unless you've got a portable
reverse osmosis device there, all you can hope for is a sterile filter
with some activated charcoal in there. If the filter is fine enough, it
might even get viruses (thought it's doubtful). Salts and small molecules
will pass through.
