Amanzi ayimithombo ebalulekile empilweni yabantu, ekukhiqizweni kwezimboni kanye nokulinganisela kwemvelo. Ukugxila okukhula emhlabeni wonke ekuvikelweni kwemvelo, amanzi okuphuza aphephile kanye nezindinganiso zokukhishwa kwamanzi angcolile ezimbonini kuye kwafaka abahlaziyi bekhwalithi yamanzi endaweni ebalulekile ezinhlelweni zokuphathwa kwamanzi zesimanje. Lezi zinsimbi zokulinganisa ezihlakaniphile zihlanganisa ubuchwepheshe bokuzwa kwe-electrochemical kanye ne-optical ukuze kutholakale njalo izinkomba zamanzi ezibalulekile kufaka phakathi i-pH, i-oxygen encibilikisiwe (DO), ukuqhuba, i-TDS, i-turbidity kanye ne-chlorine esele, okuletha idatha yesikhathi sangempela nethembekile yezitshalo zamanzi zikamasipala, ukwelashwa kwendle, amafektri amakhemikhali, ukufuywa kwezinhlanzi kanye nokuqapha amanzi okugcina amanzi emvelo. Ngokungafani nokuhlola isampula kwelebhu ngezikhathi ezithile, izinzwa zekhwalithi yamanzi eziku-inthanethi zithola ukuqapha okunganakiwe amahora angama-24, okuvumela isixwayiso sangaphambi kokungcola kanye nokulawulwa kwenqubo okunembile.
Yesimanjeabahlaziyi bekhwalithi yamanzizithembele emigwaqweni emibili yobuchwepheshe evuthiwe: ama-electrode e-electrochemical kanye namayunithi okuthola i-optical. Izinzwa ze-electrochemical zihlanganisa i-pH, i-conductivity, i-DO kanye ne-ammonia nitrogen. Inzwa ye-conductivity ye-electrode ezine, emelelwa uchungechunge lwe-WQS-EC, isebenzisa i-voltage eshintshanayo phakathi kwama-electrode e-graphite ukukala ukuhlushwa kwe-ion, nge-electrode yokubhekisela eyakhelwe ngaphakathi eqeda ukuphazamiseka kwe-polarization. I-algorithm yayo yangaphakathi ye-interpolation yamaphuzu amahlanu iguqula ngokuzenzakalelayo ukufundwa kwe-conductivity kube amanani e-TDS kanye nosawoti, ivumelana ngokuphelele nezimo zamanzi angcolile endwangu anosawoti omningi kanye namanzi olwandle. Ama-electrode engilazi ye-pH alandelela i-acidity yamanzi kanye ne-alkalinity, ipharamitha ebalulekile yokunciphisa amakhemikhali kanye nokwelashwa kwe-biochemical yendle. Izinzwa ze-optical zamukela izimiso zokusabalalisa nge-laser kanye nokucima i-fluorescence zokulinganisa i-turbidity kanye ne-oxygen encibilikisiwe, zigwema ukushintshwa kwe-membrane njalo futhi zinciphise umsebenzi wokulungisa wesikhathi eside. Izinzwa eziningi ezijwayelekile zisekela ukuxhumana kwe-RS485 Modbus-RTU, okungaxhunywa ngqo ku-PLC, amapulatifomu okulawula ezimboni kanye nezinhlelo zokuqoqa idatha ezikude ngaphandle kokuguqulwa kwesignali okuyinkimbinkimbi.
Abahlaziyi bekhwalithi yamanzi basebenzela izimo eziningi zikamasipala nezemvelo kuqala. Izitshalo zokuhlanza amanzi empompini zifaka izinzwa zamapharamitha amaningi ezindaweni zokungenisa amanzi ezingavuthiwe, amathangi okuhlunga kanye nezindawo zokukhipha amanzi eziqediwe ukuqapha i-chlorine esele, ukungcola kanye ne-pH, ukuqinisekisa ukuthi amanzi empompini ahlangabezana nezindinganiso zokuphepha zokuphuza zikazwelonke. Iziteshi zokuqapha amanzi angaphezulu nangaphansi komhlaba zisebenzisa izinzwa ezingaphansi komhlaba ukulandelela ikhwalithi yamanzi emfuleni nasemachibini, zisheshe zithole ukungcola okungazelelwe njengokuvuza kwamakhemikhali noma ukugeleza komanyolo wezolimo. Izitshalo zokuhlanza amanzi amdaka zasemadolobheni zithembele kakhulu kulezi zinsimbi ukulungisa ukungenisa umoya kanye nomthamo wokulinganisa ngokulandelela i-DO, i-pH kanye ne-COD, ukuqinisekisa ukuthi ukungcola okulungisiwe kuhambisana nemithethonqubo yokukhishwa kwamanzi kanye nokugwema izinhlawulo ezinkulu zemvelo.
Ukuqapha amanzi amdaka ezimbonini kwakha enye insimu enkulu yokusetshenziswa, ikakhulukazi emabhizinisini ezindwangu, amakhemikhali, ukudla kanye nokufaka ama-electroplating. Amanzi amdaka okunyathelisa izindwangu athwala izinga lokushisa eliphezulu, i-pH eguquguqukayo kanye ne-TDS ephezulu kakhulu enezinhlayiya zodayi kanye nezinsalela zefayibha. Izinzwa zokuqhuba ezimelana nokugqwala kanye ne-pH ezilinganisa ngokulinganisela ukuguquguquka kukasawoti kanye nesisekelo se-asidi ukuze ziqondise izinqubo zokunciphisa amanzi amdaka kanye nokuhlunga. Izitshalo zamakhemikhali ezikhiqiza i-asidi, i-alkali kanye ne-brine zisebenzisa izinzwa ze-tantalum noma ze-titanium electrode ukuze zimelane nokuguguleka koketshezi olubolayo. Izimboni zokudla nezemithi zisebenzisa ama-probe ekhwalithi yamanzi ahlanzekile ukuze ziqaphe amanzi ahlanzekile emigqeni yokukhiqiza, zivimbele ukungcoliswa kwamagciwane kanye nemikhiqizo engafaneleki. Ukumba amanzi amdaka ngama-ion ensimbi esindayo kanye nezinto eziqinile ezimisiwe nakho kudinga ukuhlaziywa okuqhubekayo kwe-inthanethi ukulawula ukuna kwensimbi esindayo ngaphambi kokukhishwa.

Ukufuywa kwezinhlanzi kuyimakethe yesicelo ekhula ngokushesha yabahlaziyi bekhwalithi yamanzi. Izinhlanzi, ama-shrimp kanye nama-shellfish anezidingo eziqinile ku-oxygen encibilikisiwe, i-pH kanye ne-ammonia nitrogen. I-DO ephansi izoholela ekufeni okukhulu emanzini, kuyilapho i-ammonia nitrogen eningi ibangela ukuntuleka kwamanzi. Izinzwa ezintantayo ezinamapharamitha amaningi zithumela idatha yesikhathi sangempela kuma-terminals eselula abalimi, zibangele ngokuzenzakalelayo imishini yomoya noma yokushintshana kwamanzi lapho izinkomba zidlula imingcele, zikhuphula kakhulu umkhiqizo wokuzalanisa futhi zinciphise izindleko zokudla nezidakamizwa.
Ngaphezu kokusebenza okuzinzile kokulinganisa, kwanamuhlaamathuluzi ekhwalithi yamanziifaka ukuthuthukiswa okuhlakaniphile okuhlanganisa ama-data logger akhelwe ngaphakathi, isinxephezelo sokushisa okuzenzakalelayo kanye nezesekeli zebhulashi ezizihlanzayo ukuze kuncishiswe imvamisa yokuhlanza ngesandla. Ngokuxhumana okujwayelekile kwe-Modbus, zihlanganiswa kalula nezinkundla zokulondolozwa kwamanzi ezihlakaniphile kanye ne-IoT yezimboni, zenza ukufunda imitha ekude, ukugcinwa kwedatha kanye ne-alamu engaphezu komkhawulo.
Ekuphetheni, abahlaziyi bekhwalithi yamanzi basebenza “njengabahloli bamanzi” abanembile kuzo zonke izimboni ezihlobene namanzi. Ukuqhathaniswa kwezinto zabo zezinzwa eziguquguqukayo, imingcele yokulinganisa ehlukahlukene kanye nokuxhumana kwedijithali okulula kuzenza zingathathelwa indawo ukuqapha ukuphepha kwamanzi kanye nokulawula inqubo yezimboni okucwengekile. Njengoba ukuphathwa kwemithombo yamanzi emhlabeni wonke kuba nzima, izinzwa zekhwalithi yamanzi eziku-inthanethi ezinamapharamitha amaningi zizogcina ukwanda kwemakethe okuzinzile futhi zibe imishini yokusekela ejwayelekile yabo bonkeukwelashwa kwamanzikanye namaphrojekthi okuqapha imvelo.
