Teaching

  • EG-338 Separation Processes II

    The course builds on Level I and II studies of traditional separation processes, extending these to multi-component systems. Short-cut methods are described. The importance of non-ideal behaviour is highlighted in descriptions of azeotropic and extractive distillation. The discussion of absorption is extended to include chemical reaction. A basic knowledge is provided of adsorption and ion exchange separation processes.

  • EG-M09 Water and Wastewater Engineering

    This module aims to deliver a working knowledge of water and wastewater treatment processes. The module will cover various physical, chemical and biological unit operations used in the treatment of water and wastewater. This module will particularly emphasise the design and operational issues related to these unit operations. Moreover, the module will cover regulatory aspects related to water quality and requirements for water and wastewater treatment.

  • EG-M11 Biochemical Engineering Principles II

    This module describes the most recent advances in the production and optimization of biological materials and processes. Optimization methods of the production of biocatalysts are described and how these are exploited in the commercial situation. The principal products of such processes are investigated to illustrate the current and future technology of these systems with an emphasis on modern biotechnology methods. The impact of the use of such techniques on quality management, safety assessment and regulatory environment are reviewed.

Dr Tizaoui with fellow researchers.

Dr Chedly Tizaoui recently joined other researchers, policy makers and companies from the world of water management this autumn to discuss wastewater legislation and technologies in a workshop organised by the FP4BATIW project. 

The event took place in Gammarth (Tunisia) in October and was attended by over 100 policy-makers, representatives of water management, end-users, and international professional organisations from Tunisia and European countries.

Sessions focused on wastewater reuse and related legislation and technologies at industrial and agricultural levels. Participants jointly discussed innovative and attractive low cost processes with consideration of the water-energy nexus adapted to the MPC region in order to build partnerships and collaborations.

A brokerage event was dedicated to establishing successful relationships between researchers and industrial companies in the MPC area. More than 250 meetings took place between leading companies in water management solutions and researchers from Tunisia and Europe.
