I haven't really been reading this thread, but watching the headers and
wondering...why should silt be a problem in a watermaker?

I thought it only made sense to use watermakes well offshore where sea
water is deep and clean...never in coastal waters where the water is not
only shallow, but polluted by runoff...and besides, fresh water is
readily available at any marina, which puts it within only an hour or
two away at most.

Silt plugs up the pre-filters sooner and may foul the
membrane too.

In many parts of the world, potable fresh water isn't
available conveniently on shore in marinas or otherwise so
you may want to make water in coastal waters.

However, I wouldn't run a watermaker in silty water if
avoidable.
