Accordingly,CUNO provides a wide variety of Filter products that meet thevarying needs of the advocated by the InternationalBottled Water Association (IBWA),CUNO supports the concept of Multi-Barrier practice. Theschematics to the right for drinkingwater and spring Water encompassmultiple points of all Filter applications may bepresent in any single facility, butare included here for This CatalogFor the purpose of this catalog,filtration applications in waterbottling operations are groupedinto the three functional categoriesas shown in the system diagram:particulate reduction, equipmentprotection, and microbiologicalcontrol.

As differential pressure builds, these com-pressible Filter structures unload particles into the Water causing an increase in ProblemSince the particle content of thesource Water can vary greatly, thesefilters must feature a high contam-inant holding capacity to addressthe range of particle loadingencountered, exhibit the structuralstability required to eliminate particle unloading under rapidchange in differential pressure,and be comprised of materialsthat will not alter the original tasteand smell.

5 To compound the particle reduction problem,variation in particle loading canbe caused by seasonal changes,such as Water table particles can consist of: Sand, silt, and general organic matter from springs or other sources, Pipe scale, rust or other particulate from transfer piping or hoses, and Debris from holding tanksand tanker car surfacesWater source filtration is requiredfor two main reasons. The first isto remove particulate from thewater to ensure the product meetsturbidity specification and target. The second reason is to protect the downstreamprocess from contamination withparticulate and organic installation locations includethe exit of the spring, bore hole,or other Water source, as well astanker filling or off-loading intothe bottling facility.

Filtration at this stage ensures product clarity that is demanded by the end 1 - Differential Pressure (psid) Turbidity control,first and foremost,is the primary concern of successful and profitable bottledwater companies. 4 Particulate ReductionThe unique rigid, graded-porosityconstruction of the Beta-Klean Filter cartridge provides efficientremoval of particulate and generalorganic debris resulting in crystalclear product manufacturing tech-niques result in a Filter that providessubstantially longer service life,and lower running costs, thancompetitive offerings. ImportantBeta-Klean benefits include thefollowing:Figure 4 -The grooves increasesurface by 65% and prevent premature blinding of the outersurface by large particles.

Additionally, the Beta-Klean Filter cartridge is rigid, andwill not unload particulate as differential pressure increases dur-ing the life of the Filter .

The condition of the system s piping and equipment, and seasonal differences further influencethe source Water s contaminant content. For this reason, CUNO offersalternative Filter selections to help meet individual user s Econo-Klean series of Filter cartridges offer consistent filtrationperformance while maintaining an economical turbidity reducing compressible string-wound or melt-blown filters, Econo-Klean filters will not deform under high differential pressure eliminating bypassand unloading of contaminants while providing long on-stream servicelife.

10 Econo-Klean filters the performance leader in cost effective filters not only outperform string-wound and melt-blowncartridges, they last longer. Figure 7 shows the amount of contaminantadded to for each Filter to reach 20 psid.
