| Abstract | Laboratory tests have established that a rapid oxidation of an acidified solution of ferrous sulphate to ferric can be achieved by passage of an air saturated solution over a film of Thiobacillus ferro-oxidans, Pilot-plant units of various types were constructed and operated to assess their oxidising efficiency using ferrous solutions ranging from 3,5 to 12 gram Fe II/litre and 3,1 to 10,5 gram H280,/litre. The best results were obtained with a plastic corrugated packing media to support the film of bacteria submerged in the iron sulphate solution thoroughly air saturated by forced aeration. The maximum specific rate of oxidation of Fe II to Fe III achieved was 7,5 gram per square metre of bacterial surface per hour. |
