Are you dealing with difficult-to-filter materials, such as colloids, fine, flocculated, or gel-like particles, or highly viscous fluids? These types of materials tend to cause problems such as low filtration rate, poor filtrate quality, wet filter cake, a quick increase of pressure drop, short filtration time in a filtration cycle, and difficult cake release. The problems are normally due to high filtration resistance either from filter media clogging, or the formation of highly resistant, or highly compactible filter cakes, which can be solved by using a filter aid. This course focuses on using filter aid to solve problems when filtering difficult-to-filter materials. Mechanisms, characteristics, and types of filter aid will be introduced, followed by filter aid selection, lab tests, plant trials, and case applications. Basic filtration principles such as cake filtration will be discussed so attendees can have a better understanding of the use of filter aids.
