
1.6.1Mechanicalcleaningofthemembrane

Itneedstobedetermined,basedontheamountofsludgepresentinthebottomofthebioreactor,
whetherafullexternalspray‐downofthemembranesis
necessaryatmaintenancetime.
Checkthesludgelevel,andifsludgecanbeeasilyseen,or
measures1cmormoreonthebottomofthetankthenthe
systemshouldbeshutdown,themembranestationwith
membranesattachedremovedfromthetank,andthe
membranesdetachedfromthemembranestationand
cleanedasdescribedinthischapter.
CAUTION:TakecarenottoloseanyoftheOringsorfibre
Washersthatareconnectedateachendofthemembranes

Sludgethathasaccumulatedontheoutsideofthefibres
(insidethebluecartridge)canbemechanicallywashedwitha
jetofwater.
TheouterringisrotatedfromtheLOCKpositiontotheOPEN
position(counterclockwise)toopenthecartridge.Thegrey
undersideofthemembranemustbeheldsecure.



TheoutergreyringcanberemovedintheOPENposition.
Thentheblueexternalcoverisfreetoberemovedfromthe
top.





Attention:
a.)Donotloosenthelargedarkgreynutslocatedatthetoptoopenthemembrane.Thereassemblingof
thecartridgeisverydifficultwithoutspecialisedtools.

b.)Aftercleaningpleasecheck,thattheexternalringislockedintheLOCKposition!


Thehollowfibresarenowexposedandcanbecarefullywashedwithawaterjet.

Note:
DamagedorcrackedfiberscansimplybeknottedbytheInstallertosealthemandthemembranewill
thenpasstheleakagetestforqualityassurance.

1.6.2.1In‐Situcleaninginthebioreactor(usualmethod)

Description:
TheAQUALOOPmembranestationremainsinthebioreactor.Foreachmembrane,2litresofcleaning
solutionarepouredintothebackwashtank.Withasemi‐automaticcleaningprocesscontrolledbythe
controller,themembranesarecleanedforonehour.Afterflushingwithclearwater,thecleaningprocess
isfinished(seeprocessbelow).

Note:
Throughoutthechemicalcleaningcycle,thegrowthbodiescanremaininthetank,theamountof
chlorineuseddoesnotaffectthebacteriaonthegrowthmedia,asitremovesonlythebiologicalbuild‐up
withinthemembrane.However,itisimportantthattheamountofchlorineusedshouldnotbehigher
thandirected(s.section1.6.3).

ChemicalcleaningroutinefortheAQUALOOPsystem:
AcleaningoptionisavailableonthecontrolmenuoftheAQUALOOPcontroller.Asemi‐automatic
cleaningofmembranecartridgescanbeperformedwithouttheneedtodismountthemembranes.

Menustepsforcleaningroutine:

Proceedtomenu11



1.) Confirmationforstartingthecleaningroutine


2.) Controllerautomaticallystartsthesludgepumpuntilthe
minimumlevelofwaterisreachedinthebioreactor(BRmin).

Note:Ifnointernalsludgepumpisconnected,thenthebioreactor
shouldbepumpedoutwithanexternal(submersible)pumpuntil
"BRmin‐"appearsinthedisplay(withasimultaneoussoundof5
beeptones)
Attention:Thesuctionpump(lowerpump)mustnotbeallowed
torundry!
Also,loweringthewaterlevelbelowwillmeanthatthesystemwill
notre‐startuntilthebioreactorlevelfillsup.

3.) Whenthecontrollershows"BRmin‐",thenabackwashprocessis
automaticallyperformedtoemptythebackwashtank.This
procedureendsautomaticallyorcanalsobeterminatedmanually.


4.) Nowthecleaningsolution(s.section11.6.3)canbeaddedthrough
thecleaningconnection.Insmalltanksystemswithgood
accessibility(e.g.AL‐GW200)thecleaningsolutioncanbefilled
directlyintothebackwashtank.
Note:Thecleaningsolutionmustberefilledduringthecleaning
processinthecasemorethanthreemembranesareinstalled,as
thebackwashtankhasonly6Lofcapacityandeachmembrane
requires2Lofcleaningsolution.

5.) Whenthecleaningsolutionisfilled,thenthecleaningcyclestarts
withENTER.Apre‐setcleaningroutinenowruns.Theroutine
takesaboutonehour.

6.) Afterthecompletionofthecleaningroutineaclearwaterflush
mustbestarted.Atleasttwolitresofclearwatermustbefilled
intothebackwashtankforeachmembrane.




7.) PressENTERtoconfirmtheclearwaterflush.Theroutinetakes

1.6.2.2Intensivecleaninginseparatecleaningtank

Description:
TheAQUALOOPmembranestationistakencompletelyoutofthebioreactorandputinaseparate
cleaningcontainer.(Ifthemembranestationiscoveredinsludgeitmustfirstbecleaned(s.section
11.6.1).Thecleaningcontainerisfilledwiththecleaningsolution(40LforAL‐CTank60Land160LforAL‐
CTank350L)andwateruptothetopofthepumpunit(700mm).Pleaseseethecleaningconcentration
described(s.section11.6.3)!
Thepumpunitisconnectedwiththecontrolunitinthestandardmanner.Thegoalistocirculatethe
cleaningsolutionundernormalpressureandflowratefor24hours.
Therefore,thestarttimesT1andT2andfiltrationcycleshavetobesetasfollows:

Starttimes:T1/T2=16:00/04:00
Suctioncycles:A1/A2=30/30

Afterthecleaningprocessthecleaningsolutionisdisposedofandclearwaterisfilledintothecleaning
containertothetopofthepumpunit(700mm).Afterflushingwithclearwaterforonehourtheused
clearwaterisdisposedof.Asecondcleaningwithclearwaterismadeinthesameway,afterwhichthe

1.7Bioreactor

PeriodiccleaningofthebioreactoritselfcontainingtheAQUALOOPisnotrequired.Theremovalofthe
sludgeisdonebythesludgepumpwhichiscontrolledbytheAQUALOOPcontroller.

However,thebioreactorcanbeinspectedbysightandsmell.
AQUALOOPisanaeratedmovingbedtreatmentandfiltrationsystem.Ifastrongodourisnoticedi.e.like
sulphur(rotteneggs),theaerationprocessmaynotbeoperatingcorrectlyorthesystemmaybe
overloadedandthebiologicaltreatmentisnotoptimal.Checktheaerationandperhapsincreasethe
aerationsetting(dissolvedoxygencontentshouldbe>4mg/Lwitharangeupto8mg/L).
TheAQUALOOPsystemtreatedoutflowshouldbeclearliketapwater.Iftheeffluentisnotclearplease
checkthetightnessofallmembranestationconnections(s.section9.1).
Shouldthebioreactorneedcleaningthetanksludgeshouldbedischargedbyasludgepump–this
processcanbedonemanuallyinthetestmode4.



1.7.1Collectingeffluentsamples

Effluentsamplescanbecollectedthroughthecleaningconnection.

Steps:
‐ disconnectthehosetothecleanwatertank
‐ decontaminatetheoutletincaseyouwanttomeasuremicrobiologicalparameters(e.g.by
disinfectionfluidorbyheat)
‐ Startfiltrationinthetestmenu“suction”.
