Ozonation and advanced oxidation by the peroxone process of ciprofloxacin in water (2009)

De Witte, Bavo, Dewulf, Jo, Demeestere, Kristof, Van Langenhove, Herman

A bubble reactor was used for ozonation of the antibiotic ciprofloxacin. Effects of process parameters ozone inlet concentration, ciprofloxacin concentration, temperature, pH and H2O2 concentration...

Bubble-free oxygenation of a bi-enzymatic system: effect on biocatalyst stability (2009)

Van Hecke, Wouter, Ludwig, Roland, Dewulf, Jo, Auly, Markus, Messiaen, Tom, Haltrich, Dietmar, ...

The effect of bubble-free oxygenation on the stability of a bi-enzymatic system with redox mediator regeneration for the conversion of lactose to lactobionic acid was investigated in a miniaturized...

Kinetic modeling of a bi-enzymatic system for efficient conversion of lactose to lactobionic acid (2009)

Van Hecke, Wouter, Bhagwat, Aditya, Ludwig, Roland, Dewulf, Jo, Haltrich, Dietmar, Van Langenhove, Herman

A model has been developed to describe the interaction between two enzymes and an intermediary redox mediator. In this bi-enzymatic process, the enzyme cellobiose dehydrogenase oxidizes lactose at...

Assessment of the integral resource consumption of individual chemical production processes in a multipurpose pharmaceutical production plant : a complex task (2009)

Van Der Vorst, Geert, Dewulf, Jo, Aelterman, Wim, De Witte, Bruno, Van Langenhove, Herman

Up to now, process specific integral resource consumption is barely used as criterion for the selection and improvement of fine chemical and pharmaceutical production processes. Reasons are the...

Levofloxacin ozonation in water: rate determining process parameters and reaction pathway elucidation (2009)

De Witte, Bavo, Van Langenhove, Herman, Hemelsoet, Karen, Demeestere, Kristof, De Wispelaere, Patrick, Van Speybroeck, Veronique, ...

Ozonation of the quinolone antibiotic levofloxacin was investigated with focus on both the levofloxacin degradation rate and degradation product formation. Degradation was about 2 times faster at pH...

Ozonation of ciprofloxacin in water: HRMS identification of reaction products and pathways (2008)

De Witte, Bavo, Dewulf, Jo, Demeestere, Kristof, Van De Vyvere, Vincent, De Wispelaere, Patrick, Van Langenhove, Herman

Degradation products formed during ozonation of an aqueous solution of the antibiotic ciprofloxacin in a bubble column are analysed by HPLC-UV high-resolution mass spectrometry. Based on the...

Ciprofloxacin degradation in water by ozonation: effects of process parameters (2008)

De Witte, Bavo, Dewulf, Jo, Demeestere, Kristof, Van Langenhove, Herman

Antibiotics belong to the so-called emerging contaminants in the aqueous environment. One of the major concerns with respect to their occurrence in the environment is the introduction of bacterial...

Exergy : its potential and limitations in environmental science and technology (2008)

Dewulf, Jo, Van Langenhove, Herman, Muys, Bart, Bruers, Stun, Bakshi, Bhavik R, Grubb, Geoffrey F, ...

New technologies, either renewables-based or not, are confronted with both economic and technical constraints. Their development takes advantage of considering the basic laws of economics and...

Cumulative exergy extraction from the natural environment (CEENE): a comprehensive life cycle impact assessment method for resource accounting (2007)

Dewulf, Jo, Bösch, ME, De Meester, Bram, Van Der Vorst, Geert, Van Langenhove, Herman, Hellweg, S, ...

The objective of the paper is to establish a comprehensive resource-based life cycle impact assessment (LCIA) method which is scientifically sound and that enables to assess all kinds of resources...

Integral resource management by exergy analysis for the selection of a separation process in the pharmaceutical industry. (2007)

Dewulf, Jo, Van Der Vorst, Geert, Aelterman, W, De Witte, Bruno, Vanbaelen, H, Van Langenhove, Herman

This paper reports a detailed analysis of the resource intake necessary for the separation of a mixture of diastereoisomers (2R, 3R)-3-(3-methoxyphenyl)-N, N-2-trimethylpentanamine 6 and ( 2R,...
