Short note on MEMBRANE TECHNOLOGY (First Half) by Izzati Razali
Week 2
Emergence of membrane technologies in wastewater treatment
categories of membrane operation
brief usage microfiltration (MF), nanofiltration (NF), ultrafiltration (UF), reverse osmosis (RO) in industries
Week 3
Membrane Application - food and beverages, industrial processes, metal removal and treatment.
the concept of membrane separation process, solid-liquid separation
Concept of fouling - parameters influence fouling, 4 fouling mechanism for porous membranes
Factors influence membrane functionality
Flux enhancement and fouling control
usage of membrane in removal of inorganic materials, organic materials and mixed wastewater.
Week 4
Theoretical aspect of MF and UF membrane system - process description
Flux, J
Feed water recovery, R
Transmembrane pressure, TMP
Total membrane resistance, Rt
Relation between water temperature and viscosity
In DESIGN of membrane, membrane flux, temperature compensation, cross-connection control and other system capacity must be taken into consideration
Week 5
Roles of Materials in Feedwater
2 types of membrane; polymeric membrane and ceramic membrane
Important property organic/polymeric membrane; eg of membrane: CA, PS, PES, PAN, PVDF, PP, PE, PVC
Inorganic membrane; eg: ceramic membrane (titania, alumina, zirconia, zeolite, silicone carbide and glass
Week 6
LEARNING OUTCOME FOR HOMEWORK 1
1) Enhance basic fundamental of membrane technology.
3) Revision on the first part of the subject are made.
2) Improve understanding on membrane application in industries.
Principles of Rejection
Rejection coefficient
Interfacial polymerization membranes
