The bioactivation procedure for increasing the sulphate-reducing bacteria in a UASB reactor

The bioactivation procedure for increasing the sulphate-reducing bacteria in a UASB reactor

Bioactivation, a procedure to obtain anaerobic sulphidogenic sludge, was developed in order to increase sulphate reduction and, consequently, sulphide production to remove metals from effluents. This procedure, in which the source of carbon/energy (lactate) is gradually replaced, consisted of three...
