Increasing Media Surface Area

High-specific-surface-area media, such as random plastic packings (np., Pall rings, siddles) and structured plastic sheets, were developed to provide more attachment sites. The goal was to offer microbes a larger footprint per unit volume of te filter. For example, corrugate sheet media can accee surface areas exceeding 200 m ² / m ³.

Optimizing Hydraulic Loading andFlow Distribution

Hydraulic loading rate (HLR) directly influences the e shear forces that affect biofilm squats andd detachment.
