Evaluation of the Combined Cr(VI) Removal Capacity of Sawdust and Sawdust-Immobilized Acinetobacter haemolyticus Supplied with Brown Sugar
TL;DR: In this article, the authors evaluated the combined Cr(VI) removal capacities of nonliving (untreated rubber wood sawdust, URWS) and living biomass (URWS-immobilized Acinetobacter haemolyticus) in a continuous laboratory scale downward-flow two column system.
Journal ArticleDOI
Cr(VI) Removal Using the Combination of the Cr(VI)-Resistant and Cr(VI)-Reducing Biofilm and the Alum-Polyacrylamide
TL;DR: In this article, the removal of chromium contamination from water systems using a combination of bacterial reduction of Cr(VI) to Cr(III) by wood husk-packed column containing the reducing biofilm followed by removal using the coagulation-flocculation technique.
