Learning outcomes

1.
Understand the thermodynamic constraints, fundamental principles, performance metrics, and the scope of physical and chemical parameters encountered in desalination processes.
2.
Analyse, synthesise, and quantitatively describe the alternative mechanisms and processes by which water is desalinated technologies.
3.
Quantitatively model the energy and mass transport phenomena controlling reverse osmosis (RO) desalination.
4.
Understand typical O&M issues with RO, including fouling, flow balancing, element selection, chemical attack.
5.
Investigate, analyse, and synthesise membrane desalination data of performance metrics and subsequently derive operational recommendations based on the synthesis.
6.
Prepare the basic pre-treatment, RO desalination, and concentrate disposal design for a typical feedwater and application setting.
7.
Understand and develop basic quantitative models for the energy and mass transfer controlling forward osmosis, membrane distillation, and multi-effect distillation processes for desalination.
8.
Propose and support creative technical innovations to meet desalination issues in the news and generate hypothetical but possible methodologies for their implementation.
9.
Utilize the technical information, theory, and concepts from RO operation and critically determine its applicability to other membrane desalination processes, both with and without phase changes.
10.
Communicate the technical methods and theories of desalination technologies and their relative environmental utility and impacts to technical and non-technical audiences.

Additional information

Unit content:The unit will cover the following topics: • Definitions, units, nomenclature, functional parameters, and performance metrics of desalination processes and technologies. • Conventional and emerging technologies for desalination, with and without phase change. • Governing fundamental and empirical equations for heat and mass transfer in desalination processes. • Primary components, configurations, and modes of operation of reverse osmosis desalination in practice, including energy recovery and pre-and post-treatment. • Factors limiting RO performance and their mitigation, including fouling, concentration polarization scaling, material degradation, and energy consumption. • Stand-alone and hybrid desalination systems involving non-RO technologies • Environmental and socio-economic considerations in desalination implementation and operation.
