TB-023 Filter Change-out : Law of Diminishing Returns

To optimize a filtration system, achieving the right balance between economy and performance is crucial. Factors such as particle characteristics, media type, and fluid properties play a significant role in determining this balance. The choice of filters involves considering filtration efficiency and dirt handling capacity. Different types of filters like membrane filters, pleated surface filters, or non-pleated depth filters may be needed based on filtration objectives. Multiple filter types might be necessary to achieve the filtration goal in complex processes.

Key highlights:

• Minimum Core Requirement: Baseline value to determine the minimum number of filters needed based on flow demand.

• Flow per Ten Inch Equivalent (TIE): Optimize flux with recommended maximum flow rates per ten inches for different filter media types.

• Filter Flow Rate: Evaluate the number of filters required based on actual filter data, viscosity, and clean delta P.

• Actual Test Data: Realistic values obtained through testing, challenging to achieve but provides accurate results for batch processes.

• Relationship between Pressure, Flow, and Surface Area: Proportionate relationship affecting filtration efficiency as particulates block media pores.

Understanding and considering these factors are essential for effectively optimizing a filtration system in terms of flow, throughput, and cost-effectiveness. Defining operational parameters is critical before making any recommendations.
