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.

Advantages of MARPAK MXF Series 60° flow media:

1. Superior oxygen transfer

The MXF Series geometry allows for the continuous and uniform horizontal redistribution of air and water (Fig. 4-1) maximizing oxygen uptake.

2.High Efficiencies at shallow depths

The MXF Series 60° cross corrugated geometry maximizes hydraulic retention time compared to other media types (Fig. 4-2 &

4-3). MXF Series media can provide effective treatment at media depths as low as 3 ft MXF Series media can be used as a direct replacement for rock media to increase both capacity and efficiency of existing trickling filters (Fig. 7-1).

3. Wide hydraulic range

MXF Series is effective in reducing BOD and nitrification at hydraulic wetting rates of below 0.2 gpm/ft2 to over 2.5 gpm/ft2.

MARPAK MCR Series

MARPAK MCR Series is a vertically corrugated clog resistant media designed to minimize the potential for excessive solids buildup. The geometry is ideally suited for treating high strength wastewater. Typical applications are shown in Figure 5-1. MCR Series media is available in modules 2 ft wide,

2 ft, 4 ft, 6 ft or 8 ft high and 4 ft long.
