The Sulphur Reactor SR 400 is a bio-reactor filled with sulphur beads which promote the growth of the specialised bacteria that remove nitrate. As a bi-product of the biochemical reaction that takes place in the SR 400, sulfuric acid is produced and in consequence the SR 400 must always be used in combination with a Hydrocarbonate Reactor HR 400 in which the sulfuric acid is neutralized. Both reactors are supplied with a strong holding system.
