· Fast start-up of a pilot-scale deammonification sequencing batch reactor from an activated sludge inoculum. Jeanningros Y, Vlaeminck SE, Kaldate A, Verstraete W, Graveleau L. Water Sci. Technol., (6):1393-1400 MED: 20351417 The sequencing batch reactor (SBR) is a fill-and-draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor, treated to remove undesirable components, and then discharged. Equali zation, aeration, and clarification can all be achieved using a single batch reactor. To optimize

Using a Sequencing Batch Reactor Ana C. Rodrigues, Antonio G. Brito, Luis F. Melo ABSTRACT: This study concerns the application of a sequencing batch reactor (SBR) for the posttreatment of an effluent rejected by an upflow anaerobic sludge blanket (UASB) reactor operating in a brewery. The batch experiments were conducted over 6 months to get effect of ratio of inoculum-substrate on the acclimatization of pharmaceutical effluent. The tests were carried out in batch reactors, serum bottles, of volume 2000 mL and plastic canes of 10000 mL. Each inoculum was filled with a cow dung, sewage and phosphate buffer.

Example 1: Isothermal batch reactor, first-order reaction An isomerization reaction is carried out in a batch reactor. The reaction is first-order, both isomers are liquids with a density of 900 3kg/m at 163 °C. The reactor is filled in 10 minutes and emptied in 12 minutes. To design the batch reactor of 22 m3 the parameters mentioned were considered, the design equations were formulated and graphic solution was performed based on these parameters. Finally sizing batch reactor was carried out, which measures are: height 4.23 m and diameter 2.82m, and construction material selected was AISI 316 stainless steel.

1.3 Fed-Batch Cultures 3 1.3.1 Reasons for Fed-Batch Cultures The fed-batch culture has been practiced since the early 1900s, when it was recog-nized inyeast production from malt wort that the malt concentration inthe medium a batch, fed-batch or continuous bioprocess. In batch fermentation, microorganisms are inoculated to a fixed volume of medium in a fermentor. With microbial growth, the nutrients are gradually consumed and by-products accumulate. Therefore the culture environment is continuously changing. The broth is removed at the end of the run.
