Installation
MARPAK is installed so that the sheets of all
modules in a particular layer are parallel.
Special care should be taken during installation
of the media to protect the modules from
damage. Where necessary, cutting and
trimming of the modules may be performed
within the fixed film reactor. Adequate
protection and precaution should be taken to
insure that no damage is done to the placed
media and that no debris from the cutting
process is allowed to lodge in the placed
media.
Warranty
The media supplier shall certify to the general
contractor and the engineer in writing that
the media to be supplied will meet or exceed
the specifications. Limited warranty shall be
provided by the manufacturer for a period of
one year after installation against defects in
material and workmanship.
For a more detailed specification for your
specific application, please contact
SPX Cooling Technologies at 800 462 7539
and ask for MARPAK.
Media
MARPAK is a Modular PVC media specifically
designed for fixed film biological treatment
applications.
MARPAK is available in both the highly
efficient 60° cross flow design (MXF Series) for
complete secondary treatment and nitrification
and the vertical flow design (MCR Series) for
treating high strength industrial wastewater.
MARPAK media is available in specific surface
areas from 30 to 74 square feet per cubic foot
with a 95% void to volume ratio.
The MARPAK modules are manufactured in
various PVC sheet thicknesses to meet specific
structural requirements.
Material
MARPAK polyvinyl chloride (PVC) sheets are
resistant to rot, fungi, bacteria growth and other
forms of microorganisms and are chemically
resistant to normal concentrations of sewage
acids, alkalis, organic solvents and organic
compounds.
The PVC compound is UV resistant and
specifically formulated to resist long-term
fatigue cracking under continuous loading.
