Design and Operation of Membrane Systems in Municipal, Mining and Industrial Applications

IWES, University of Queensland, WaterAid membrane systems

Target Audience

Chemists, engineers, planers and operators involved in water and wastewater treatment using membrane processes. The modules are based on recent case studies and developments in membrane equipment. Numbers will be limited.

Description

A selection of courses on design and operation of membrane plants in a range of applications that can be taken as single days or multi-day modules. Each day is self-contained and offers a practical, problem based approach to design and operation of membrane systems in municipal, industrial and mining applications. (Discounts apply for multi-day enrollment, 3 -5 day registration options available).

Each module (course day) includes a design problem covering water quality, equipment selection and sizing, data collection and interpretation, operating strategies, trouble shooting and cost estimating. Participants will receive detailed notes for each module, including worked solutions and copies of design software for design of ultra-filtration, reverse osmosis and membrane bioreactors. Additional activities include demonstration of membrane repair, membrane module displays and a visit to a full scale membrane plant.
