a solid – liquid – gas, multiphase reactor, called inverse fluidized bed bioreactor (ifbbr) was used in this study for the treatment of starch industry wastewater of high organic content and acidic nature. mixed culture obtained from the sludge, taken from starch industry effluent treatment plant, was used as microorganisms. experiments were carried out in an inverse fluidized bed bioreacto...

Packed bed bioreactors were used to remove soluble manganese from a synthetic mine water as the final stage of an integrated bioremediation process. The had undergone initial processing using sulfidogenic bioreactor (pH 4.0–5.5) which removed all transition metals present in elevated concentrations (Cu, Ni, Zn and Co) apart manganese. aerobic packed with pebbles collected freshwater stream that...

in this paper, experimental data on the drying kinetics of corn in a packed and fluidized bed are presented. experimental research was conducted on a laboratory apparatus. corn was used as a material because of its significance in agriculture and the food industry. an analysis of the influence of the operational parameters (the drying medium velocity i. e. the fluidization number, the drying me...

The biological degradation of perchlorate was examined using a laboratory-scale, autotrophic, packed-bed biofilm reactor. The reactor was operated in unsaturated-flow mode and continuously fed water containing perchlorate (ClO4-) (as an electron acceptor), and a gas mixture of hydrogen (5%) and carbon dioxide at a retention time of 1.5 min. In the absence of nitrate, perchlorate removal rate (r...

The purpose of this work was to optimize the pretreatment process of wheat straw by Polyporus brumalis_BRFM985 in order to improve carbohydrate accessibility for more efficient bioconversion. Indeed, there is growing demands to develop sustainable routes for lignocellulosic feedstocks valorization into value-added products in energy, chemicals, materials, and animal feed fields. To be achieved,...

In this work, the recovery of Cu from large waste printed circuit board (PCB) pieces by biogenic ferric sulphate at high solid to liquid ratio was studied. PCB parts were packed in a column and constantly recirculated. A oxidation reduction potential (ORP) decrease observed leaching due ion consumption; drop caused slower copper dissolution kinetics. After 25 days, 62.2% leached PCBs column. co...
