DURA-PAC
Trickling Filter Media
DURA-PACis a self-supporting PVC sheetmedia, capable ofwithstanding loadsin excess of industrystandards. DURA-PACmodules are availablein various sizes and
specific surface areasof 30, 31, 48 or 68 ft2/ft3.
DURA-PAC is a plastic sheet mediaavailable in two basic designs. DURA-PACXF is a cross flow media recommendedfor low to medium BOD loadingapplications. DURA-PAC VF is a verticalflow media recommended for high BODloading applications. DURA-PAC's
volumetric void ratios of at least 95% allowfor uniform redistribution of wastewaterand air while maximizing contact betweenthe biomass and the wastewater.
DURA-PAC is available in specific surfaceareas of 30, 31, 48 and 68 ft2/ft3. 31 ft2/ft3
media is typically used for BOD removaland 48 ft2/ft3 media can be used fornitrification to reduce the size of newnitrifying trickling filters.
The DURA-PAC media is non-toxic tomicroorganisms and immune to rot. Itis resistant to degradation by ultravioletlight, fungi, bases and acids, and othercompounds normally found in wastewater.
DURA-PAC consists of thermoformed flatPVC sheets. Sheets are sized in variedthicknesses indexed to applications. Forcross flow applications (DURA-PAC XF)these sheets are corrugated horizontally
and bonded to one another in a
honeycomb pattern module. Vertical flowmedia modules (DURA-PAC VF) areformed by alternating flat and corrugatedsheets. DURA-PAC modules typicallymeasure 2' x 4' x 2'. Custom modulesizes are available. DURA-PAC sheetscan also be shipped to the job site forassembly, if the application requires.
DURA-PAC is one of five trickling filtermedia designs from JaegerEnvironmental. Jaeger Environmental hamanufactured trickling filter media since1979, with system installations worldwideWe offer random and structured media fomunicipal and industrial applications.
Product specifications for DURA-PACare detailed on the reverse side of thispresentation. For further information,or to discuss your application, contactJaeger Environmental via phone, fax ore-mail.

DURA-PAC TRICK LI NG FILTER MEDIA
A. Standard Product Specifications1. The media shall be fabricated from rigid PVC
sheets completely corrugated forming across-corrugated pattern with adjacent sheetsto permit continuous horizontal redistributionof both the air and wastewater throughout thedepth of the media. The PVC roll stock sheetsshall be of uniform thickness with no sectionsless than 0.002 inch manufacturingtolerance. The media shall be specificallydesigned for use in the biological oxidationof municipal and industrial wastewater.
2. The polyvinyl chloride used in the media shallbe resistant to degradation from ultravioletradiation, rot, fungi, bacteria and other formsof microorganisms. The media shall bechemically resistant to concentrations ofcommon inorganic mineral acids or alkaliesand organic solvents or compounds normallyexperienced in sewage.
3. Each module shall consist of several
PVC sheets, bonded together to form a
structurally self-supporting block measuring24'' wide x 24'' high x 48'' or 72" long. Themodules shall be designed with a minimumspecific surface area of 30 (or 31, 48 or 68)square feet per cubic foot with a minimum95% void volume ratio. Each module shallbe capable of withstanding a minimum load
of 35 pounds per square foot per foot ofmedia depth. Maximum allowable deflectionshall be limited to 2%.
4. The manufacturer shall submit test reportsfor the mil thicknesses to be supplied.Testreports shall comply with the requirementsof paragraph C. If there are no test reportsor if there are any alterations to the mediain respect to materials or design, themanufacturer shall test the modules inaccordance with paragraph C.
5. Individual sheets used in the manufactureof the media shall conform to commercialstandards ANSI/ASTMD1784-78:12454C withthe following physical properties when testedin accordance with the method indicated:
B. Installation1. The media shall be placed inside the filter by
crane or mechanical conveyor. The mediamodules shall be transported by cranes orplaced on wooden slides or conveyors to theworking level. The media modules shall beplaced by hand in their final location.
2. Use 1/2 inch thick plywood, pegboard or othersuitable temporary planking to protect themedia from foot traffic. Do not allow workersto directly walk or stand on the media.
3. Place each module as close as possible toeach other while avoiding damage to themodules. The sheets of all modules in a layershall be placed parallel to each other in orderto maximize uniform and continuous horizontalmovement of air and water.
4. Modules in each layer shall be rotated 900
to the layer immediately below to enhancewater redistribution and to maximizeself-supporting of the media.
5. The media modules shall be carefullytrimmed or cut to fit within 2 inches (50.8 mm)or less of the center column. Cut or trimmodules to fit within 2 inches (50.8 mm) orless of the filter perimeter wall.
6. Shaping, trimming and cutting of the mediamay be done in the filter provided appropriatemeasures are taken to prevent any chips,broken pieces or similar debris from fallinginto the media. Canvas or similar workingmaterials shall be used to cover the mediamodules. Before a new layer of modules isadded, the existing layer shall be cleared ofall construction material or objects that mayhave fallen on it. The top layer of media shallalso be protected from damage caused byfalling material due to any subsequent workuntil start-up of the system.
7. The media modules in the bottom layer shallbe placed on the supports provided. Supportledge (a minimum of 4 inches wide) shouldbe provided around the center column andthe tank perimeter wall. The top of the supportbeams and ledges should be at the sameelevation and within a maximum tolerance
of 1/8 inch (3.18 mm) in their elevation.
C. Module Testing1. Structural testing of fabricated modules sha
be performed by an independent testinglaboratory approved by the engineer.
2. All tests shall simulate service conditions anconform to the following criteria.
a. The test samples shall consist of a stackof modules at least two modules high. Tarrangement of the stack shall simulatethe geometry as placed in the filter towe
b. Modules intended for the base layer shabe tested on a simulation of the supportsystem. Modules intended for all otherlayers shall be tested on a flat base.
c. Test loads shall be the design loads of tmedia specified.
d. The test load shall be uniformly applied a temperature of 75F, ( 2F) and thedesign load shall be applied as follows:
1. A pre-load, equal to 10 percent of thdesign load, shall be applied for 1 hoto seat modules and to establish abaseline flexural condition.
2. The loading shall be increased in 10pound-per-square-foot intervals. Eacloading shall be held for a minimum
5 minutes and the deflection recordeat the end of the 5-minute period.
3. Incremental loading shall continue urecorded deflections are 1 percent asubsequently, 2 percent.
e. Maximum allowable compressive deflecof the individual modules shall be 2percent.
f. If more than 10 percent of the modulestested in any strength gradation exhibita compressive deflection of greater than2.0 percent, or if any one module exhibia deflection greater than 4.0 percent,additional testing may be required asconsidered necessary to determine thestructural suitability of the media. If thetests indicate the media is structurallyunsuitable for its intended use, the medimay be replaced with new media meetinthe specifications and passing thestructural testing.
D. Product Handling And Storage1. If storage is required, assembled media
modules shall be stored on a flat, cleansurface to prevent damage to the moduleedges.
2. Modules should be checked at least once pweek. Modules that may have fallen shall beinspected for any damage and undamagedmodules should be restacked and secured.Damaged modules should be either repairedor discarded.
3. During shipment and storage, modules shaalways be stacked on their long face with thplastic sheets in a vertical position. Modulesshall not be stacked more than four high,and modules in each layer shall be set atright angles to those below. Weathered orotherwise damaged media are not acceptaband will be replaced as deemed necessary oappropriate.
E. CleaningAs installation of each module layer is completemodules surfaces should be inspected for thepresence of debris or other construction materiaAny foreign material detected should be removeand all surfaces cleaned. Upon completion of thmedia installation, a final check of the mediasurface should be conducted for the presence oforeign material and any material detectedremoved prior to the application of water. Followcompletion of the inspection and the removal of foreign material, the media should be thoroughly
flushed with clean water.
