AccuPac® Vertical Flow Media

AccuPac® Vertical Flow Media Modules are designed to remove carbonaceous and nitrogenous BOD while providing anti-fouling characteristics for biodegradation of municipal and industrial wastewaters in trickling filters, anaerobic reactors, and similar biosystems. The modules are fabricated from rigid PVC sheets, which are UV-protected and resistant to rot, fungi, bacteria, acids, and alkalis commonly found in municipal wastewater.

Superior Solids Flushing
The open geometry and vertical orientation of the AccuPac Vertical Flow Media is designed to shear away excess biosolids, thereby reducing the potential for plugging. Without sharp angles or pockets where excess biomass might accumulate, a thinner biofilm is retained, minimizing loss of effective surface area.

Vertical Flow Advantage
The mid-module splash slope distributes the wastewater onto the thin biofilm, ensuring superior process performance. This unique flow pattern increases redistribution, oxygen transfer, and substrate removal rates.

Enhanced Structural Integrity
Each AccuPac vertical flow sheet is a combination of flat and corrugated segments, improving the structural integrity of the assembled modules. Brentwood’s patented “dedicated glue joints” feature ensures a precise and complete solvent bonding of the sheets for a uniform and homogenous module with superior structural strength. The AccuPac VF-5000 module consists of 12 sheets per one-foot module width as compared to a 60° crossflow module with similar surface area and voids which consists of 10 sheets. This higher material content per unit of surface area further enhances the module’s structural integrity.
