Notes:
An upflow fixed-bed sulphate-reducing reactor has been set up and monitored for thetreatment of metal-bearing wastewater. Zinc has been chosen as the target metal to be sequesteredfrom influent water stream at initial concentrations ranging from 50 to 400 mg/l and initial pHvalues ranging from 3 to 5. Main operating parameters of the reactor, such as the composition andcontent of electron donor, electron acceptor, sulphate and metal removal capacity, have beenmonitored during ten months of continuous operation. The results obtained have shown that thereactor has a considerable capacity of completely reducing sulphates for initial concentrations up to7,200 mg/l, completely removing soluble zinc for initial concentrations up to 400 mg/l andcompletely removing Total Organic Carbon (TOC), for initial concentrations up to 1,500 mg/l
