Required Courses

Introduction to Global Filtration Market

From the air we breathe to the water we drink, filtration has affected almost all aspects of our daily life and industrial processes, such as power generation, food & beverage, pharmaceutical, environmental protection, data centers, high-tech devices, and transportation, etc. This course aims to provide the audience with an overall understanding of the global filtration market, current increasing demands, challenges, opportunities, and trends.


Air Filtration

This course will give you a fundamental understanding of air filtration principles, technologies, and applications in various market segments, such as HVAC, transportation, industrial dust removal, gas turbines, paint spray booths, clean rooms, hot gas filtration, air purification, personal protection, etc. The current emerging high demands for air filtration associated with COVID and healthier environments will also be discussed, along with new developments and trends in the global filtration market.


Air Filter Design

This is an advanced course in air filtration to discuss air filter design principles and processes, including key product characteristics, customer requirements, filter media and configuration selection, prototype and lab testing, field test and validation for various applications, such as HVAC, transportation, industrial dust removal, gas turbines, paint spray booths, clean rooms, hot gas filtration, air purification, personal protection, etc. The new product designs, evaluation standards, and trends for future development will also be discussed.


Nonwovens in Filtration

This course will provide an overall understanding as to what nonwovens are and how they are different from other fabrics. The topics that will be covered include: (i) Nonwoven products and markets; (ii) Polymers and fibers used in nonwovens; (iii) Nonwoven production – web formation and Bonding; (iv) Dry-laid and Wet-laid formation of webs; (v) Direct web formation from polymers; (vi) Web bonding technologies – mechanical, thermal and chemical; (vii) Finishing of nonwovens; and (viii) Nonwovens testing and characterization. Advantages and disadvantages of these processes, as well as their flexibilities and  limitations will be deliberated. Because of the enormous opportunities and continuing innovation, nonwoven sector continues to enjoy sustainable growth for foreseeable future. Recent innovations and developments, as well as the options available for the industry to develop new products in filtration will be discussed.


Particulate/Air Separation

This course will discuss the techniques of particle removal from air streams not covered in air filtration, but also popularly used in solid/gas separation processes, such as gravity and momentum separation equipment, centrifugal separators, Wet scrubber, electrostatic precipitators, etc.. Outline 1. Gravity and momentum separation equipment 2. Centrifugal separators 3. Wet scrubber 4. Electrostatic precipitators 5. Others


FIlter Media Technologies

Filter media technology is the core and competitive edge of modern filtration technologies. From nonwovens, membranes, ceramics, metallics, adsorbents, wovens, to nanofibers and other porous materials, this course aims to provide you an overall understanding of the filter media market and products used in various areas of air and liquid filtration. Emerging technologies, challenges, and trends for future development will also be discussed.


Gas Phase Filtration

The objective of this course is to help you get an overall understanding of gas phase filtration market and technologies for air purification in terms of removing harmful gases, VOCs, and odors, etc. It covers basic principles, different types of adsorbents and their functions in use, delivery systems of adsorbents, products in different application markets, such as HVAC, odor control, environmental exhaust, toxic gas protection, and the product evaluation methods and standards. The new opportunities and trends for future development will be also discussed.


Air Filter Evaluation and Testing Methods

This course is intended to provide a broad understanding of the test methodologies and techniques used in developing non-woven air filtration media and manufactured end products. Specific focus is given to a wide variety of application driven developments and covers HVAC, automotive, industrial, clean spaces and medical applications, among others. The course also covers elements concerning the use and abuse of published testing protocols and how they interact with global market needs. Additionally, emphasis will be given on how the data quality must be assessed and utilized for meaningful project outcomes.


Facemask Market and Technologies (elective)

The objective of this course is to provide the audience with the latest update on facemask market analysis and a depth understanding of the technologies used to make facemasks, especially meltblown electrostatic changing technologies, as a primary method used for making core facemask filtration layers. We will also discuss new updates on test methods and certification standards for the facemasks, as well as nanofiber technologies used in facemask applications, emerging new developments, opportunities, and trends.


Clean Air Strategies for Public Health (elective)

This education webinar aims to provide you with the latest developments in filtration clean air strategies for public health. It discusses Air filtration technologies for clean indoor & outdoor air, what the requirements are for IAQ control and healthy buildings,  value propositions of smart buildings and how technology can be leveraged to ensure IAQ, wellness, and decarbonization, how residental filters and air purifiers impact the air quallity at home and some recent updates from ASHRAE ETF for filtration/air cleaning recommendations.
