HowToSelecttheChlorineSolutionStrengthandPumpSetting

Thegoalofaproperlyfunctioningchlorineinjectionsystemistohaveafree‐chlorineresidualof0.2to1.0

ppmaftersufficientcontacttime,beforeanycarbonfiltersystem.Orifnocarbonfilterorotherde‐

orfurthestpointintheplumbing.

ThiscanbeaccomplishedbyadjustingthechlorinebleachsolutionstrengthandsettingtheStennerFeed

RateControlDialuntilyouachievethedesiredresidual.



Indeterminingyourmeteringpumpssettingsandsolutionstrength,keepinmindthatitsbesttomakeup

freshsolutiononceevery1to3months.Thechlorinesolutionlosesstrengthasitages,andissensitiveto

heatandlight.Generally,keepsolutiontankoutofthesunandusefreshsolutionregularlyforbestresults.



StepOne:Determineflowrateofthewaterstreamyouareinjectinginto,inGallonsPerMinute(GPM)

1.Openanyhosebiborfaucetuntilpumpturnson.

2.Closehosebiborfaucetandletpumpfilluppressuretankuntilitturnsoff.

3.Usinga1or5gal.bucket,openfaucet,collectandmeasureallwaterdischargeduntilpumpturnson.

4.Whenpumpturnson,immediatelyclosefaucetandstarttimingpumpcycle.

5.Whenpumpturnsoff,recordpumpcycletimetorefillpressuretankinseconds.

6.DividethenumberofgallonscollectedinStep3bythenumberofsecondsinStep5.

7.MultiplytheanswerfromStep6by60.

8.TheanswerinStep7istheaveragepumpingcapacityofthepumpingallonsperminute(GPM).



StepTwo:HowMuchChlorineShouldBeInjected?Determinethepartspermillionofchlorineyouare

tryingtoachieveinpartspermillion(PPM).



Chlorineisinjectedinpartspermillion('ppm')whichisthesameassayingmilligramsperliter('mg/L').The

amountofchlorinetoadddependsonthe“chlorinedemand”ofthewater.Chlorinedemandistheamount

ofvariouscontaminantsinthewaterthatcombinewiththechlorineafterthechlorinehasbeeninjectedand

sufficientcontacttimehasoccurred.Afterthechlorinehascombinedwiththevarioussubstancessuchas

bacteria,iron,manganeseandodor,somelevelofuncombinedor“free”chlorinewillexist.Thegoalisto

havesomesmallamountoffree‐chlorine,usuallyaround0.2to0.4ppmoffree‐chlorine,uptoamaximumof

1.0ppmoffree‐chlorine.

Forbacteriayouwanttoinject1–2ppmofchlorinewithapproximately10minutesofcontacttime.Ifthe

wateriscolderthan50F(10C)and/orthepHishigherthan7.5youmayneedlongercontacttimeorahigher

residual.

Foreachpartpermillionofironormanganesegenerallyyouwanttoinject1ppmofchlorine.Foreach1.0

ppmofhydrogensulfidegas(whichcausestherotteneggsmellinwater)youwanttoinject2to3ppmof

chlorine.Sosayyouhavebacteriaand2.0ppmofiron.Forourexamplehere,wewillassumeyouwantto

inject3ppmofchlorine.

StepThree:Determinewhatsolutionstrengthofbleachtouse



Householdbleachisapproximately5%chlorine;poolchlorineis10to12%.5%isthesameassaying50,000

partspermillion(PPM)and10%isthesameassaying100,000PPM.

Regardingthesolutionstrength:Ifyoudilutethebleachbyusing1gallonsofpurewaterto1gallonof

householdbleach,youendupwithsolutionstrengthofapproximately2.5%or25,000ppm.Inotherwords,

householdbleachhasasolutionstrengthof50,000ppm,andifyoudiluteitwith1gallonofwater,youend

upwithsolutionstrengthof25,000ppm.

Regardingsettingtheoutputofthemeteringpump:Youcanvarytheapplieddosageofchlorinebyadjusting

thechlorinebleachsolutionstrengthandsettingtheStennerFeedRateControlDialuntilyouachievethe

desiredresidual.

Afteryouusetheformulabelowtocomputethegallonsperdayadjustthepumptoendupwiththedesired

applieddosage.Theformulaissimple,youonlyhaveto:

MultiplytheFlowRate(ingallonsperminute)timestheAppliedDosageinPartsPerMillionDesiredtimes

1440.ThendividebytheSolutionStrengthinPPMthatisbeingused.



Example:Assumethatyouhaveawellpumpthathasaflowrateof12gallonsperminute(12GPM)and

thatyouwanttoinject3.0ppmofchlorineintothewater.Youhavedecidedtouseasolutionstrengthof

25,000ppmor1gallonof5%bleachtoonegallonofpurifiedoratleastsoftenedwater.Thereare1440

minutesin24hourperiod,andtheformulawilltellyouhowmanygallonsofchlorineyouwilluseforevery

24hoursthewellpumpruns.

Theformulais:12GPMx3.0PPMx1440andthendividedby25,000=2.07GallonsPerDay

Thismeansthatyouneedameteringpumpthathasanoutputof2.0gallonsperday.Youcanusethe

Stenner45MHP2,whichhasamaximumoutputof3gallonsperday,andsetthepumpatthe66%level,since

2is66%of3,themaximumoutputofthepump.Theoreticallythiswillgiveyouanappliedchlorinedoseof

3.0ppm,andyoucanadjustitlateronceyoudetermineyouractualfree‐chlorineresidual.TheStennerpump

hasaFeedRateControlDialwithnumbersfrom1to10.Ifyousetthepumpat6orbetween6and7,youwill

havethedesiredadjustmentof66%.


