Course Objective
The biggest challenge of liquid filtration is in its vast variety and applications of equipment used. Liquid filters, although all use for liquid filtration, their designs, operations and applications can be very different. This course follows the “Liquid Filtration” course and provides a more detailed understanding of major types of equipment used in liquid filtration with the focus on industrial applications. Practical information and examples based on the instructor’s extensive field experiences are used to help the audience understand these liquid filters.
The contents are designed for people who are new to the filtration industry either in technical, sales or business functions. It is also a very good refreshing course for those who have been involved in filtration for a while, especially in relating fundamental principles to practical operations.
After the course, participants will have the basic knowledge and practical insights to select, design, and evaluate filtration processes across various industries, including water treatment, food & beverage, pharmaceuticals, energy, electronics and more.
