`Background
`FillerTEK technology allows paper-
`makers to increase the sheet ash
`content up to five points without
`compromising quality of their prod-
`uct and operations. Controlled size
`distribution and excellent stability of
`
`filler flocs provides strength, while
`other sheet and printing properties
`are well maintained. At the same
`time, the drying energy is substan-
`tially reduced. Increased content of

`Essential Expertise
`for Water, Energy and Air
`
`Background
`FillerTEK technology effectively
`delivers cost efficiency to paper
`producers by allowing them to
`utilize less expensive raw materials.
`This patent-pending technology is
`based on preflocculation of filler in a
`controlled manner to produce flocs
`with a defined size distribution and
`improved shear stability. The net
`result is that the treated filler can be
`incorporated at higher levels in the
`sheet without a loss of strength or
`optical properties. This technology
`was demonstrated on a world class
`coated, woodfree machine in Asia,
`enabling the mill to increase the
`base sheet ash level three to five
`percent, resulting in a total of over
`
`a combined $16 MM savings in raw
`material and energy cost.
`
`Business Situation
`The world class paper machine at
`this mill was producing coated, base
`paper at 60-120 gsm basis weight
`that contained approximately 17
`percent sheet ash, using a mixture
`of PCC and GCC filler. At this mill,
`the key business driver for the use
`of FillerTEK technology was overall
`raw material cost savings. The mill
`had been purchasing market pulp
`at a cost of about $650/ton, using
`both GCC and PCC filler on-site,
`with the cost of filler being less than
`$100/ton. Therefore, a one percent

`
`
`
`filler content increase meant more
`than $5.50/ton in raw material cost
`savings to the mill. In the past, mill
`personnel had made many attempts
`to raise the filler content. With
`increased filler content, sheet
`quality, especially strength
`properties, suffered, and the
`overall machine runnability also
`decreased.
`
` Program Design
`
`After a careful review of this mill, it
`was determined that FillerTEK
`technology would be an ideal fit
`to help this facility meet its over-
`all goals and business objectives
`through a program combining
`chemicals and equipment. As
`illustrated in Figure 1, Nalco
`provided the facility with a filler
`preflocculation skid. The skid
`effectively mixed two Nalco filler
`preflocculation agents with filler
`slurry and then produced stable
`filler flocs in a defined particle size
`distribution. The preflocculated filler
`flocs were then sent to the filler daily
`tank before feeding to the paper
`machine.

`
`Program Results
`The implementation of FillerTEK
`technology helped this mill increase
`its base sheet ash level from 17
`to 22 percent. The critical sheet
`properties, including internal bond
`strength, tensile strength, stiffness,
`optical properties, porosity and
`roughness were all maintained after
`the five percent ash increase, as
`illustrated in Table 1. Trial samples
`also passed the mill’s print test
`evaluations.
`
`The mill started to utilize FillerTEK
`technology across all grades in
`2010. Since then, it has been re-
`ported that filler content of all grades
`increased three to five percent,
`while keeping good machine
`runnability. Due to filler content
`increases, steam consumption
`was also reduced significantly.
`The average steam consump-
`tion per ton of base paper in every
`month is illustrated in Figure 2.
`The average steam consumption
`was 1.6 tons per ton of base paper
`before the full implementation of
`FillerTEK technology, and this was
`reduced to about 1.25 tons with
`FillerTEK technology. This meant
`that 0.35 ton steam was saved per
`ton of base paper with FillerTEK
`technology.

`
`Conclusion
`With an average of 4 percent filler
`content increase in the base sheet,
`the mill was able to realize $22/ton
`savings in raw material cost, or over
`$14.0 MM of cost savings annually.
`Additionally, the mill benefitted from
`energy savings due to the reduc-
`tion of steam consumed in the dryer
`section. On average, 0.35 tons of
`steam were saved for every ton
`base paper produced, or 455,000
`MM BTU annual energy savings.
`Since less fiber was being used, the
`energy to refine the fiber was also
`reduced. With a 4 percent filler con-
`tent increase from 17 percent to
`21 percent, or fiber content reduc-
`tion from 83 to 79 percent, it is
`estimated that about 5 percent of
`refining energy will be saved, or
`8.6 MM kwh in annual electricity
`savings. The annual cost savings
`was estimated to be $1.7 MM due
`to steam consumption reduction,
`and $0.6 MM due to refining energy
`saving. Overall, FillerTEK
`technology helped the mill to
`realize over $16.0 MM total cost
`savings. The chemical cost to the
`mill is about $3.5 MM, resulting in a
`ROI of over 450 percent.
`
`As a result of this successful
`technology program integration,
`this mill was able to successfully
`meet their goals and improve their
`overall operating efficiency,

`cost, saves drying energy costs and
`effectively increases a mill’s profit-
`ability. The treatment of fresh filler
`is done directly in the process with
`no holding time required before use
`and with minimal adjustments to
`typical wet-end and papermaking
`processes.
`
`Business Situation
`A European Specialty Free Sheet
`producer needed to improve its
`cost position to remain a viable
`entity in their market space. The
`paper machine at this facility used
`market pulp as a main component
`of papermaking furnish. Recent
`years’ increase in pulp prices from
`€350/ton to approximately €600/ton
`dramatically reduced the mill’s fi-
`nancial performance. The customer
`believed that increased filler loading
`would help return their mill to a more
`profitable position with the substitu-
`tion of high-cost fiber with five times
`lower filler cost. A recommendation
`by Nalco to implement FillerTEK
`technology was made to help this
`customer’s mill achieve their goals.

`
` Program Design
`
`Based on the current machine fur-
`nish and ash levels, Nalco recom-
`mended to run a FillerTEK technol-
`ogy trial to help increase base sheet
`ash by five points. The mill’s current
`filler addition strategy was to add all
`fresh filler in the suction side of the
`thick stock pump. Nalco proposed
`installing its preflocculation equip-
`ment into the process to treat the
`filler and then add the treated filler
`to the thin stock before the head-
`box fan pump. During the machine
`trials, the amount of broke was kept
`constant; the sheet ash content
`originating from broke was approxi-
`mately 50 percent of the total ash.
`The higher sheet ash target was
`then obtained by adding fresh filler
`to achieve the increased levels.
`
`The preflocculation equipment was
`installed in the vicinity of the mill’s
`filler supply tank with minimum
`installation work. After the treatment,
`the preflocculated filler was trans-
`ferred into the run tank and from
`there dosed into the process by
`using a low shear feed pump. Good
`floc size and proper shear stability
`were also maintained from the treat-
`ment up to the dosing point.
`
`Controlled floc size and shear stabil-
`ity are typically monitored using
`particle size measurement instru-
`ments to ensure proper treatment
`is occurring while running FillerTEK
`technology. Properly treated filler
`will usually increase in size, as indi-
`cated in Figures 2 and 3.

`
`Program Results
`The implementation of FillerTEK
`technology helped this mill increase
`its base sheet ash level on average
`from 15 to 19 percent. The critical
`sheet properties, including internal
`bond strength, tensile strength,
`stiffness, optical properties, poros-
`ity and roughness were all main-
`
`tained after the ash increase. Trial
`samples also passed the mill’s print
`test evaluations. Table 1 illustrates a
`summary of the results from 80 gsm
`grade used in offset printing.
`
`With an average of four points ash
`increase in paper, direct savings in
`fiber replacement are estimated to

`
`Key Performance Indicators
`(KPIs)
`This customer agreed to run several
`trials of the FillerTEK technology
`program. Prior to chemical evalua-
`tion, Nalco worked with the mill to
`establish KPI’s for the trial, which
`included:
`
`•
`
`Increase sheet ash by four to five
`percent.
`
`• Maintain sheet quality, strength,
`and optical properties
`
`• Maintain production quality
`
`• Maintain printability on offset and
`rotogravure grades
`
`
`
`Conclusion
`This producer of specialty
`free sheet products needed to
`improve its cost effectiveness
`through increased filler loading.
`The machine had been running
`at 15 percent sheet ash and was
`producing 150 tpd. The mill ran
`several successful filler loading
`increase trials over a two month
`period utilizing FillerTEK tech-
`nology. With the help of Nalco,
`the customer now has the ability
`to increase sheet ash 5 points
`without negative impacts to sheet
`quality or machine runability.
`Implementation of FillerTEK
`technology also met the Key
`Performance Indicators and
`provided for achievement of the
`primary drivers for this machine.
