HPPC Filters: High Capacity Positively Charged, Dual Layered PES Membrane

By Critical Process Filtration

High-capacity filtration is essential when processing liquids with elevated particulate or biological loads, where standard approaches can quickly lead to fouling and inefficiency. Dual-layer membrane design addresses this challenge by combining a high-capacity prefilter with a sterilizing-grade final layer, enabling extended service life and consistent filtration performance.

Positively charged membrane technology enhances removal of negatively charged contaminants such as endotoxins, viruses, and cell debris, supporting improved purity outcomes in demanding applications. At the same time, low binding characteristics help preserve sensitive compounds like proteins and preservatives, reducing product loss and maintaining formulation integrity. With validated bacteria retention and compatibility across a wide pH range, this approach supports reliable performance in process water and high-purity environments.

To cut changeouts and improve throughput, teams need to understand how capacity and charge-based filtration work in tandem to boost efficiency. Access the datasheet to learn more.
