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/ft
2
to over 2.5 gpm/ft

.
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.

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.
