the sediment sinks to the bottom, but don’t use the tap if it is near the bottom.
Get some siphon tubing with a u-bend or upside-down snorkel at the bottom and an inline tap so you can turn it off between bottles, and try to keep it still to avoid disturbing the sediment.
bigger Boots stores used to do all this gear but I think you’d need a homebrew specialist these days
You’ll also need to raise the fermenting barrel a bit – I used to put mine on a chair/stool, but a couple of layers of breeze blocks should be enough, as long as you can get the whole of the bottle below the bottom of the bucket – so I’d do that before you start the kit.
Don’t try to get every last drop out of the fermenting bucket either, when you can see the sludge getting sucked into the siphon, pull it out and you might need to discard that bottle, unless you’re very patient.
<edit> didn’t see what bawbag had put, doh! </edit>
Finings shouldn’t be necessary to clear it – leave it for a couple of weeks in the bottle & you should have some nice clear beer. Check with your local homebrew store for current advice.
