Iinkonzo zamanzi zaseMelika ziyaphelelwa ngabasebenzi. Ubudala obuqhelekileyo bomqhubi wezityalo zokunyanga amanzi eziqinisekisiweyo eMelika bungaphezulu kwama-50, kwaye i-American Water Works Association ibhale phantsi inani elifanayo leendawo zokusasaza amanzi, izitishi zokunyusa amanzi, kunye nezibonelelo zonyango kufuneka zigcinwe ngabantu abambalwa, abadala, nababiza kakhulu.
Ukubeka iliso kwi-chlorine ngokwembali kube ngomnye wemisebenzi enzima kakhulu kwinkqubo yamanzi. I-analyzer ye-intanethi esekwe kwi-DPD eqhelekileyo ifuna ingcali ukuba izalise ii-reagents rhoqo emva kweveki e-1 ukuya kwezi-4, kuxhomekeke ekusetyenzisweni. I-sensor ye-amperometric egqunywe yi-membrane ifuna ukuphinda ifake ii-electrolyte kunye nokutshintshwa kwe-membrane rhoqo. Kwinkampani esebenza kwizikhululo ze-chlorination ezingama-40 ezixhasa i-chlorination kulo lonke isixeko, loo mthwalo wokulungisa uguqulela ekubeni ingcali enye ichithe malunga neentsuku ezimbini ngeveki iqhuba phakathi kwezikhululo - ukutshintsha ii-reagents, ukutshintsha ii-membranes, ukulinganisa kwakhona.
Iintsuku ezimbini ngeveki zexesha lomqhubi we-$45 ngeyure, qho ngeveki, ubomi benkqubo. Elo lixabiso eliphantsi kwemeko yokuthobela imithetho ye-EPA yeMethod 334.0. Yiyo loo nto inani elikhulayo leenkonzo zaseMelika zitshintshela kwi-sensor ye-chlorine engena-reagent, engena-membrane.
1Ingcamango yeMveliso: Susa into esetyenziswayo, Susa utyelelo
I-Honde online residual chlorine sensor isebenzisa i-voltage engaguqukiyo kwiiringi ezimbini zeplatinum ezifakwe ngqo kumsinga wamanzi. I-free chlorine esabela kumphezulu we-electrode ivelisa umsinga ohambelana noxinzelelo lwayo. I-sensor iguqula oku kube kukufunda kwi-mg/L, iyikhuphe ngaphezulu kwe-RS485 Modbus-RTU, kwaye ihlawulela ubushushu ngokuzenzekelayo.
- Akukho reagent yokuzalisa kwakhona
- Akukho membrane enokutshintshwa
- Akukho electrolyte yokugcwalisa
- Utyelelo lwekota xa kuthelekiswa nolweveki nganye
- Ukonga imali yonyaka kwe-$600 kwisitishi ngasinye
- Ixesha lomqhubi eli-1,000 leeyure elibuyiselweyo
Kuthungelwano losasazo lwezikhululo ezingama-40, oko kuthetha ukuba yi-$24,000 ngonyaka kwizinto ezisetyenzisiweyo ezisusiweyo kunye neeyure eziqikelelwa kwi-1,000 ngonyaka zexesha lomqhubi elibuyiselweyo.
2Imeko 1: Ukusasazwa kweChlorin yeMunicipal Distribution Booster
Iinkqubo zokusasazwa kwe-US ziyafuneka ukugcina intsalela ye-chlorine ebonwayo kuzo zonke iindawo kwinethiwekhi - uMthetho we-EPA weTotal Coliform ufuna uvavanyo lwentsalela kwindawo nganye yesampulu eqhelekileyo, kwaye uMthetho weSigaba sesi-2 seZibulali-ntsholongwane kunye neZinto eziHlanganisiweyo umisela ubuninzi be-4.0 mg/L. Phakathi kwe-"ebonwayo" kunye ne-"4.0 mg/L" kukho ibhendi yokusebenza apho izixhobo zilawula khona ngokwenene: ngesiqhelo i-0.5 ukuya kwi-1.2 mg/L, ihlengahlengiswa ngokwexesha lonyaka.
Izitishi ze-booster chlorination zilapho le band ilawulwa khona. Izitishi ze-booster zongeza i-chlorine emanzini ahambe iiyure ezininzi ukusuka kwisityalo sonyango kwaye alahlekelwe yintsalela ngenxa yemfuno yombhobho kunye nomthwalo wendalo. I-sensor yesitishi isoloko ilinganisa intsalela kwaye iqhuba ipompo yedosi ukubamba indawo emiselweyo.
Imfuneko ye-EPA Method 334.0 yisango lokuthobela imithetho: ii-analyzer ze-chlorine ezikwi-intanethi ezisetyenziselwa ukuthobela imithetho kufuneka zihlangabezane nemigangatho yokwamkelwa kwale ndlela. Umgaqo wokulinganisa i-amperometric we-sensor ye-Honde kunye nokuchaneka okubhaliweyo (±1% FS) ziwubeka kwindawo yokufakela ehambelana ne-Method 334.0 kwizityalo zonyango nakwiindawo zokusasaza.
Isensa iqhagamshela ngqo kwi-SCADA yesikhululo nge-RS485 Modbus interface — zonke iinkonzo zamanzi zaseMelika zisebenzisa i-SCADA, kwaye i-Modbus lulwimi lwenkobe lwazo zonke ii-RTU kunye ne-PLC kwishishini.
3Imeko yesi-2: Iinqaba Zokupholisa Izakhiwo Zorhwebo
I-engile yeLegionella yeyona nto ibangela imfuno ekhula ngokukhawuleza. I-ASHRAE Standard 188-2021 ifuna ukuba abanini bezakhiwo baphumeze iNkqubo yoLawulo lwaManzi esemthethweni kwiinqaba zokupholisa — kwaye amagunya amaninzi ase-US, kuquka neSixeko saseNew York, aye ahambela phambili ngemithetho yasekuhlaleni eyalela ukubhaliswa kweenqaba zokupholisa kunye nokuhlolwa komgangatho wamanzi.
Inqaba yokupholisa yindawo efanelekileyo yeLegionella: amanzi afudumeleyo, ama-30–40°C, atyebileyo kwizakha-mzimba ezivela kuthuli lomoya, kunye nokuveliswa kwe-aerosol okusasaza naluphi na ungcoliseko kulo lonke ummandla. Icebo lokulawula kukuthatha i-chlorine okanye i-bromine ukuze kugcinwe intsalela kwi-tower sump, kudityaniswe nokubeka esweni rhoqo.
Imarike yobunjineli bezakhiwo ibisoloko isebenzisa uvavanyo olulula lwe-test-strip okanye i-DPD-kit — umphathi wesakhiwo ufaka i-strip veki nganye aze abhale umbala ofanayo kwi-clipboard. Loo ndlela iyasilela xa ibaluleke kakhulu: phakathi kovavanyo lweveki nolulandelayo, inqaba inokutshintsha ukusuka kwi-0.3 mg/L (ekhuselekileyo) ukuya kwi-0.0 mg/L (engalawulwayo) ngexesha lobushushu obonyusa imfuno yamanzi kunye nokusetyenziswa kwe-chlorine.
I-sensor engena-reagent itshintsha uqoqosho lwesakhiwo. Ifakwe kumgca wokujikeleza kwesakhiwo senqaba, iqhagamshelwe kwinkqubo yolawulo lwesakhiwo nge-RS485, i-sensor ixela i-chlorine eseleyo rhoqo. I-BMS iyalumkisa xa i-residual iwela ngaphantsi kobuncinci obucetyiswa yi-ASHRAE.
Uyilo lweSisombululo seMisebenzi yase-US
I-sensor ifakwa kwi-bypass loop kwindawo ye-chlorination. I-Data logger enesikrini kwisikhululo ngasinye ibonisa i-current residual kunye ne-trend yeeyure ezingama-24. Ilabhoratri ye-utility isebenzisa i-Handmeter ngexesha lokuqinisekiswa kwekota - isampulu yokubamba ehlalutywe ngesalathiso esiphathwayo kwaye ithelekiswa ne-sensor efakiweyo.
Isiphumo se-RS485 Modbus-RTU siqhagamshela ngqo kwi-PLC okanye kwi-RTU yesikhululo. Kwiimpahla ezisasaziweyo, izinzwa zithumela nge-GPRS, 4G, WIFI, LoRa, okanye iimodyuli ezingenazingcingo zeLoRaWAN, ezipakishwe kwifomathi ye-MQTT Json, ukuya kwi-SCADA ephakathi okanye kwinkqubo yolawulo lwesakhiwo.
I-Cloud server kunye nesoftware zidibanisa idatha ye-chlorine kuzo zonke iindawo ezijongiweyo. Inkqubo ye-Alarm relay isebenza kwi-control loop: xa intsalela iwela ngaphantsi kwe-0.5 mg/L ubuncinci, i-relay ilungisa ipompo yedosi kwaye inyuse ii-alamu ziye kumqhubi okhoyo ukuba kuyimfuneko.
Iziphumo zasentsimini: Uncedo lwamanzi oluseMzantsi-mpuma we-US, ngo-2026
Inkonzo kamasipala ephakathi kumzantsi-mpuma we-United States, ekhonza abathengi abangama-380,000 kwiindawo ezintathu, ithathe indawo yabahlalutyi be-DPD-reagent ngee-sensors zeHonde ezingenazo ii-reagent kwizikhululo ezingama-28 ze-booster chlorination kunye neendawo ezimbini zamanzi ezigqityiweyo zezityalo zonyango.
Iziphumo zokusebenza emva kweenyanga ezi-4:
- Izikhululo zokunyusa amandla ezingama-28 ziye zayeka ukutyelela kwazo rhoqo ngeveki ukuze zizalise i-reagent, zatshintsha zaba yimijikelo yokuhlola yekota. Le nkampani ifumene iiyure zomsebenzi eziqikelelwa kwi-880.
- Iindleko ezisetyenziswayo kwizikhululo eziguquliweyo zehle ukusuka kwi-$16,800 ukuya kwi-zero ngelo xesha.
- Inkqubo yokudlulisa i-Alarm ifumanise ukusilela kwe-dosing-pump kwimizuzu embalwa emva kokuhla okushiyekileyo - ngaphambili, ezi ntsilelo beziza kubonwa kutyelelo lwesikhululo lweveki elandelayo.
- Akukho kwaphulwa kwemithetho ebhaliweyo. Iqela lenkampani yokuthobela imithetho likhankanye idatha eseleyo eqhubekayo njengephakheji yamaxwebhu enamandla kakhulu eyakha yaveliswa ukuze kuhlolwe urhulumente.
- Izinzwa ezimbini zezityalo zonyango ziphumelele uphononongo lokuqala lokwamkelwa kwelizwe ngaphandle kokukhetha.
