5 day course
To gain an understanding of the design principles, practice and operational experience of conventional and advanced chemical treatment processes.
key principles of chemical processes including kinetics, thermodynamics, solubility and fate
- the role of solubility in chemical processes including precipitation, scaling and corrosion
- adsorption of organics by activated carbon, kinetics and equilibria. batch and column operation, biological effects, carbon regeneration, applications
- ion exchange resins, ion selectivity, column operation, regeneration of resins, co-flow and counter-flow, applications, including demineralisation, water softening, removal of nitrate and heavy metals
- coagulation science and application in water and wastewater treatment, role of floc formation and growth
- oxidation of trace or anics: chlorine, ozone, hydrogen peroxide and other oxidants, principle of advanced oxidation processes
- disinfection principles and key issues: formation of by-products
- UV irradiation: applications for low and medium pressure lamps
- the selection of chemical processes for specific contaminant removal.
On successful completion of this course the delegate will be able to:
- Identify the range of conventional and advanced water and wastewater treatment processes for the removal of dissolved impurities (including toxic metals and trace organics) and the inactivation of pathogenic organisms.
- Understand the underlying chemical principles on which the processes are based, and be able to apply these principles to unit process design and operation.
- Be able to select appropriate processes for specific applications, and have some knowledge of practical design considerations.
- Execute and asses laboratory work examining disinfection by-products (FT).
