These two courses are to introduce the basics of solid/liquid separation (or called liquid filtration) from the industrial application perspective. Practical information and examples will be used to relate to fundamentals. It is designed for people who are new to the filtration industry either in technical, sales, or business functions. It is also a very good course for those who have been in this industry for a while to get a better understanding of correlating fundamentals to practical applications. With the wide spectrum of solids/liquid separation technology and to meet the audience’s interests, this course is designed into two parts, I & II. Each part can be taken independently but it is recommended to take both.

In part, I, simple underlining principles of key solid/liquid separation technologies, types of liquid filter and selection criteria will be presented. Technologies to improve filtration and separation such as filter aid, coagulation and flocculation are also part of the curriculum.

In part II, key types of solid/liquid separation equipment will be discussed individually, including all types of filters, gravity settlers and centrifugal separators. Basic operation principles, application guidelines and key testing and evaluation methods will be presented.
