Brentwood Trickling Filter Media is a structured-sheet media that is largely responsible for the success of performing trickling filters. Unlike outdated rock fill, PVC modules have superior compressive strength and higher void volumes, which are necessary for stacking. Greater specific surface area allows for higher organic loadings and process efficiencies. All Brentwood trickling filter media is fabricated from rigid, self-extinguishing, un-plasticized PVC sheets with UV protection. The material is resistant to rot, fungi, bacteria, acids, and alkalis commonly found in wastewater.
Combining high surface area with maximum mixing points per unit volume of media, cross flow media facilitates superior process performance in a wide range of hydraulic wetting rates.
The open geometry and vertical orientation of this media is designed to shear away excess biosolids, thereby reducing the potential for plugging.
As the optimal configuration of media in deep towers, mixed media combines the superior distribution of cross flow media and the reduced plugging potential of vertical flow media, yielding consistent and efficient biological wastewater treatment.
