Dairy industry wastewater is rich in organic content, presenting a high biodegradability, and therefore biological treatments are widely employed. This study aimed to evaluate biosolids production three systems: activated sludge (AS), movingbed biofilm reactor (MBBR), sequencingbatch (SBMBBR). Simulated dairy was used at different load rates (OLRs): 1.22, 2.87, 5.44 gCOD L−1d−1. Besides product...

Abstract: The selection of a suitable type of reactor for the reaction with enzymes immobilized on the carriers is extremely important to industry. In this study the possibility of using pre-selected cellulose-based carriers (Granocel) to conduct the reaction in a stirred batch reactor and a fixed-bed reactor was investigated. It was shown that non-activated Granocel did not undergo compression...

This study investigated soluble organic nitrogen (sON) activity in batch reactors mimicking nitrifying moving bed biofilm (MBBRs). work was divided into two objectives focusing on the production and degradation of sON, respectively. For first objective, a synthetic feed that did not contribute any used results indicated irrespective presence influent carbon (0 versus 400 mg COD/L) reactors, sON...

Lignocellulosic biomass is a renewable resource used to produce energy, fuels, and chemicals. This study aimed determine the effect of pyrolysis temperature on product yield characterization bio-oil. In this study, palm shells were selected prepared as raw materials for bio-oil production. Palm first soaked in 10% HCl then pyrolyzed at temperatures 300 oC, 350 400 450 oC fixed bed reactor. Afte...

the cane alcohol vinasse assessment on the removal efficiency of a fixed biomass anaerobic reactor (fbar) was evaluated. crude vinasse was used to feed the reactor. the fbar was operated with organic load rate (olr) of 0.5, 1, 3 and 6 gcod/l/d. removal efficiencies of 85, 82, 75 and 66 per cent were observed respectively. the fba reactor presented an excellent removal of organic matter, however...

Abstraet---A new development in the field of internals in packed columns is the use of structured packing types. Recently, a new structured packing type coated with a thin alumina layer (KATAPAK rM) has been developed, in this report, the results of an experimental and theoretical study concerning the possible applicability of this new packing material for hydrogenation processes in a trickle-b...

Different types of solar photocatalytic reactors exists in the literature for water treatment, Thin-film fixed-bed reactor (TFFBR) is one of them which is used in this study because of its high surface area to volume ratio for water treatment. TFFBR is an inclined plate coated with P25 TiO2 DEGUSSA over which contaminated water flows during treatment. The TFFBR also contains a pump, by which th...

Thiobacillus ferrooxidans was used in fixed-film bioreactors to oxidize ferrous sulfate to ferric sulfate. Glass beads, ion-exchange resin, and activated-carbon particles were tested as support matrix materials. Activated carbon was tested in both a packed-bed bioreactor and a fluidized-bed bioreactor; the other matrix materials were used in packed-bed reactors. Activated carbon displayed the m...
