In this paper recent semi-batch chromium sludge processing is compared with batch processing by simulation means mainly. A possible time and/or power consumption reduction using these two techniques is monitored to optimize the process. The process itself is strongly exothermic so the temperature control is necessary to keep the temperature under critical temperature point.
This paper presents a comparison between batch and three different sets of fed batch fermentations forrhamnolipid production by Pseudomonas aeruginosa. The batch run was performed with 500 ml of culturemedium having the initial glycerol and sodium nitrate concentrations of 30 and 8.3 g/l, respectively. For a fedbatch run with nitrogen source in feed, 250 ml of the nitrogen exc...
This paper presents a novel distributed batch Gaussian process upper confidence bound (DB-GP-UCB) algorithm for performing batch Bayesian optimization (BO) of highly complex, costly-to-evaluate black-box objective functions. In contrast to existing batch BO algorithms, DBGP-UCB can jointly optimize a batch of inputs (as opposed to selecting the inputs of a batch one at a time) while still prese...
Batch-wise variations, called intra-batch evolution here, widely exist in batch processes. In this paper, intra-batch evolution is tracked and monitored for multiphase batch processes. First, a batch cycle is divided into multiple phases. Within each phase, sliding windows are constructed for analysis of intra-batch relative variations, based on which different process modes are separated in or...
The present study deals with the batch and fed-batch mass production of Steinernema carpocapsae. S. carpocapsae is an entomoparasitic nematode that is used as a biological control agent of soil-borne crop insect pests. The ability and efficiency of fed-batch culture process was successful through the utilization of the nematode’s bacterial symbiont Xenorhabdus nematophila. Results from the fed-...
in this research degradation and mineralization of ortho-toluidine (ot) in the wastewater of petrochemical industries was investigated by uv/tio 2 process in a batch recirculating photo reactor. the influence of different variables such as initial ph, amount of tio 2 and initial concentration of ot on the reaction rate was investigated. in optimum conditions (1.75 g/l of catalyst, ph at 7 and i...
