They are referred to as SLAD reactors, old school wastewater treatment
For all the basic info on SLAD reactors and wastewater you should try this web site

They are easy to build, and in terms of aquarium literature try

And here for a DIY design (which I would modify per my comments below)

For a discussion of its use in aquariums try this link

The SO4 build up is not as much a problem as you would think given that levels of sulfur in mixes are lower than sulfur levels in seawater.

Mix the sulfur and the limestone (Aragonite) in a column followed by a pure aragonite column. The mix in the first chamber helps keep the ph up throughout the "sulfur" column (low ph reduces denitrtrfication rates)

Hope this helps
