- Page 4 Modular Biological Treatment Media MARPAK is a modular PVC corrugated media specifically designed for biological treatment applications. MARPAK media is manufactured from rigid PVC sheets that are UV protected and resistant to rot, fungi, bacteria, acids and alkalies commonly found in wastewater. MARPAK modules are manufactured in various sheet thicknesses to meet specific structural requirements.
- Page 5 MARPAK MXF Series MARPAK MXF Series incorporates the well established 60° cross-corrugated (cross flow) design (Fig. 4-1). This geometry has proven to be the most efficient for reducing BOD (biochemical oxygen demand) and for nitrification. Typical applications are shown in Figure 5-1. MXF Series media is available in modules 2 ft wide, 2 ft or 4 ft high and 4 ft or 6 ft long.

Page 6: General Design Information
General Design Information Municipal Wastewater Numerous empirical equations have been developed in an attempt to mathematically describe the reaction taking place in the trickling filter. The most common and generally accepted empirical equation in use today for predicting trickling filter performance in secondary treatment applications is the modified Velz equation. - Page 7 Applications Upgrading Existing Rock Trickling Filters MARPAK MXF 4800 with its 60° cross fluted geometry and high surface and void ratio is ideal for upgrading the performance of existing rock trickling filters. With a surface area and void ratio more than three times greater than rock, upgrading with MARPAK MXF 4800 can more than double the organic capacity and improve effluent quality of...

- Page 10 The MARPAK Advantage Fixed film media has traditionally been made in 2 ft height increments due to production limitations (sizes of thermoformers and molds to create the media sheets). Marley cooling tower fill has been produced for over 30 years and the advantage of taller fill heights has been recognized.
