MAINTENANCE TheSulLoggersensorhasnoactivefoulinghandling,andthe sensor head therefore needs periodic cleaning. The necessary cleaningfrequencydependsverymuchonthetypeofwastewater andontheturbulencearoundthesensor. Stagnantwatergives idealconditionsforbiofouling,andwhenchoosingamountingpo-

sitionitisthereforeadvisabletolookforapositionwithrelatively highow/turbulence. For new installations it is recommended to clean and calibrate thesensoronetimeperweektoensurestableoperations. When moreexperiencehasbeengainedontheactualfoulingrateatthe installationsite,thismaintenancefrequencymaybechanged. CLEANING TheSulLoggersensorsdurabledesignmakescleaningeasy.

CALIBRATION TheSulLoggersensorcomesfactorycalibratedandisassuch ready to use immediately as received. However, calibration in 7

ommended to calibrate the sensor before installation and sub-

sequently once every month, but this can be subject to specic installationconditions. Thecalibrationprocedureissimpleandhasnodemandforaccess toSCADAvaluesorconnectionofcomputer/laptoporotherdata viewingdevices. ThecalibrationroutinereliesontheSulLogger sensors internal detection capability of the calibration gas and on the presence of a magnetic switch which is activated by the calibrationcap. Anumberofdifferentindicatorlightmodesgives signal to the operator of what to do during the calibration, as described below. The position of the indicator light is shown in Figure1.

SULFILOGGERSENSORSEWER INSTALLATIONS-TIPSANDTRICKS When installing the SulLogger sensor for monitoring hydro-

gensuldeinsewernetworksthefollowingnotesmayserveas guidelinesforamonitoringcampaign:

Hydrogen Sulde (H2S) is created under oxygen free con-

ditionsinthesewerwhichtypicallyoccursinForceMains

(pumpedsewerlines). TheconcentrationofdissolvedH2S increaseswhentheresidencetimeand/ortemperatureof thewastewaterincrease.

Thiscanbeasimpleoverowtogravitationalsewer lines,apumpsumpforasubsequentForceMainspumpline, abuffertankorsimilar. The easiest and recommended way of deploying the Sul-

LoggersensorforH2Smonitoringinsewernetworksis toinstallthesensorwithaconnectingpipeprotectingthe cables. Thepipemustbesecuredtoeitherthesewerwallor atthetop/inletscreen. ThedissolvedH2Sisreleasedtogasphaseduringtherst stretchofanaeratedsewer. Theexactdistanceofrelease dependsonmanydifferentparameterssuchasturbulence andventilationconditions,butingeneralitisadvisableto measure as close to the end-of-pipe of the Force Main as possibletogetarealisticmeasureoftheinitialH2Sconcen-

tration. TheSulLoggerS1/X1-1120-5mgLsensorcanbemounted ataccesspointsdirectlyontheForceMain. Thiscaneither 20



be done by attaching the sensors threaded tting to the pressure pipe or through a dedicated load-lock system at thechosenpositiononthepipe. Notehowever,thatliquid velocities are often high in pressurized pipes, and hence thereisanincreasedriskofsensordamageassociatedwith thistypeofmeasurements. IngeneralitisrecommendedthattheSulLoggersensor ismountedinawaywhereitiseitheralwayssubmergedor alwaysoutofthewater(intheheadspace). Interpretation ofdatacanbedifcultiftheSulLoggersensorisintermit-

tently submerged. Furthermore, a mounting at a position wheretheSulLoggersensorgetsinandoutofthewater often leads to an increased risk of biofouling and scaling, whichsignicantlylimitsthetimewithreliabledatainaeld deployment. 21



TROUBLESHOOTING Problem: The SulLogger App does not recognize the SulLog-

gersensorwhenitisconnected(version1010only). Solution: TrychargingthebatteryofthePowerComBox,ortry disconnectingthewirefromthePowerComBoxtothesensorand reconnectitsubsequently. Problem: TheSulLoggersensorisshowingvaluesclosetozero all the time even though grab sample analysis of the medium showssignicantsuldeconcentrations. Solution: TheinletoftheSulLoggersensormybeblockedby fouling. Tryrinsingthesensorandgentlywipingthefrontwitha wetcloth,takingcarenottoapplyforcearoundtheinletsofthe sensingelements. Ifthemeasurementsareperformed inliquid phase(e.g. inwastewater),checkthe pH-valueoftheliquid. Ifthe mediumisalkaline(above pH-8)thenthedissolvedsuldeispri-

marilyonthe HS-form,whichisnotdetectedbytheSulLogger sensor. For slightly alkaline pH-values (pH-7-8), the pH-effect can be corrected for, but for higher pH-values, we recommend usingtheSulLoggersensorinalow-volumesidestreamreac-

tor,wherethewastewaterisacidiedtoensurethatalldissolved suldeisontheH2S-form. Problem: TheSulLoggersensordoesnotmeasurecorrectval-

uesaccordingtoourstandardtests. Solution: When judging the accuracy of the SulLogger sen-

sor we always recommend to apply a gas phase measurement withgasfromapre-mixedgasbottlecontainingaknownH2Scon-

centration. Please note that the accuracy (grade) of gas bottle 22
