Population Balances

This work aims at modeling in detail the polymerization of non-ionized acrylic acid in aqueous solution. The population balances required to evaluate the main average properties of molecular weight were solved by the method of moments. The polymerization process considered is initiated by a persulfate/metabisulfate redox couple and, in particular, the kinetic scheme considers the possible formation of mid-chain radicals and transfer reactions. The proposed model is validated using experimental data collected in a laboratory-scale discontinuous reactor. The developed kinetic model is then used to intensify the discontinuous process by shifting it to a continuous one based on a tubular reactor with intermediate feeds. One of the experimental runs is selected to show how the proposed model can be used to assess the transition from batch to continuous process and allow faster scale-up to industrial scale using a literature approach.

The work is focused on the assessment of possible methods for intensification of photocatalytic degradation of common water borne pollutants. Solar photocatalysis poses certain limitations for large scale application with several possible reactor designs which have shown an optimal performance. In the current study, a comparison between two types of pilot scale reactors was made: a flat-plate cascade reactor (FPCR) and tubular reactor with a compound parabolic collector (CPC). Apart from the reactor design, another aspect of possible intensification was a photocatalyst formulation. The efficiency of photocatalytic films that consisted of pure TiO2 nanoparticles was compared to the efficiency of films that consisted of TiO2/CNT composites. Intensification assessment was performed via detailed kinetic modelling, combining the optical properties of films, irradiation conditions and reactor mass balance. Intensification was expressed via intensification indices. Results showed the advantage of the CPC-based reactor design and an unbiased effect of sensitizing agent (CNT) in the photocatalytic film formulation.

Abstract The potable use of harvested rainwater is limited, mainly due to contamination with various pathogenic microorganisms. Disinfection of microorganisms by solar photocatalysis is emerging as a promising technique for drinking water treatment. The present study deals with the preparation of Ag-doped TiO2 by the sol gel method, and its immobilization over the inner surface of the Pyrex glass pipes used in fabrication of pilot-scale reactors. The solar photocatalytic efficiency of the reactors was tested for the disinfection of microorganisms in tap water and roof harvested rainwater. The photocatalytic experiments under solar irradiation illustrate that doping with silver ions significantly increases the inactivation rate of all microorganisms compared with pure TiO2 and direct photolysis. The inactivation efficiency against various microorganisms was found in the following decreasing order: E. coli>MS-2 phage>Aspergillus spores. The roof harvested rainwater was completely disinfected in addition to chemical oxygen demand (COD) removal, within 120 minutes of solar irradiation. The experimental cycle was repeated several times to study the stability of the reactor. The pilot-scale solar photocatalytic fixed bed tubular reactors were found to be very effective for the disinfection of rainwater for potable use.
