4-Day Master Course Pre-treatment, Membrane Fouling and Scaling
The course includes theory and practice of pre-treatment, fouling and scaling in ultra- and micro-filtration applied for drinking and industrial water production. The impact of the water source – seawater, river water, brackish groundwater and (treated domestic) waste water – will be discussed in depth.
Topics:
Introduction
– Desalination and membrane related technologies. Water sources, applications, capacities and cost.
Ultra- and microfiltration
– Summarizing principles. Membrane materials, pore size, flux, normalizing permeability and fouling mechanisms.
– Overview ultra- and micro-filtration elements and systems.
– Fouling in MF/UF systems, fouling control and pre-treatment.
Reverse osmosis and nano-filtration
– Summarizing principles. Flux, salt passage, rejection and
concentration polarization.
– Overview of RO and NF membranes and elements. Single
and multiple staging.
– Summarizing process design of RO systems with spiral
wound elements. Osmotic pressure,Net driving pressure.
Permeate quality and flux.
– Normalizing data in RO and NF systems in practice.
– Fouling in RO and NF systems. Spacer and bundle fouling.
Suspended and colloidal matter, iron and manganese,
biofouling, organic fouling and scaling.
– Conventional pre-treatment techniques for RO and NF.
Media filtration, coagulation, sedimentation and flotation.
Particulate fouling and pre-treatment
– Fouling due to suspended and colloidal matter. Mechanisms of fouling.
Parameters to predict fouling. SDI/MFI (0.45) and MFI-UF.
– Value of fouling predictions with SDI/MFI (0.45) in RO/NF and UF systems.
