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 
an existing trickling filter. A significant amount of 
nitrification can also be achieved, depending on 
the organic loading.

Unlike rock or random plastic media, MARPAK 
MXF 4800 provides continuous and uniform 
horizontal redistribution of air and water, with 
no short-circuiting. In addition, MARPAK MXF 
4800 has no horizontal surfaces, thus minimizing 
the potential for excessive solids buildup and 
plugging.

MARPAK MXF 4800 modules can be placed 
directly on rows of supports (Fig. 7-1) Removal 
of the existing clay tile along with the rock media 
is recommended. Modifications to the existing 
trickling filter structure are generally not required.
