Module Description: This module begins with the methods used to characterise individual particles and particulate systems, then moves on to particle-fluid interactions and separations.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Describe the properties, characterisation methods and sampling techniques used for particulates.
LO2 Explain the interaction between fluids and individual particles as well as fluids and packed columns.
LO3 Design and select industrially used solid-fluid separation processes and equipment and explain their operation and safe use.
LO4 Solve problems involving equipment size, product throughput, particle separation and operating parameters.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed

Requirements

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
