Qhov zoo ntawm dej ntws raug soj ntsuam los ntawm Lub Chaw Haujlwm Ib Puag Ncig los ntawm qhov kev pab cuam Kev Ntsuam Xyuas Qhov Zoo Dav Dav (GQA) thiab nws yog ib qho tseem ceeb uas yuav tsum tswj cov tshuaj lom neeg uas muaj peev xwm ua rau muaj kev phom sij hauv dej. Ammonia yog ib qho khoom noj khoom haus tseem ceeb rau cov nroj tsuag thiab cov algae uas nyob hauv dej ntws. Txawm li cas los xij, thaum qhov kub ntawm dej ntws hloov pauv, cov ammonia ionized hloov mus rau cov pa roj ammonia uas tsis yog ionized. Qhov no ua rau cov ntses thiab lwm yam tsiaj txhu hauv dej tuag taus, yog li nws yog ib qho tseem ceeb uas yuav tsum saib xyuas cov ammonia tas li.
Qhov zoo ntawm dej kuj tseem ceeb rau cov chaw kho dej uas siv dej ntawm tus dej ntws ua lawv qhov chaw. Cov ammonia ntau hauv dej tuaj yeem ua rau muaj teeb meem loj rau cov txheej txheem tua kab mob. Los ntawm kev ntsuas cov ammonia hauv dej ntawm qhov nkag ntawm lub chaw kho dej kom zoo, lub koom haum tuaj yeem tiv thaiv cov dej nkag. Hauv qee qhov kev siv, qhov nkag tuaj yeem kaw thaum cov ammonia nce mus txog qib siab tsis txaus siab.
Cov txheej txheem saib xyuas ammonia tam sim no kim thiab nyuaj, siv cov electrodes xaiv ion thiab cov tshuaj reagents kim, muaj tshuaj lom thiab nyuaj rau tuav. Cov saib xyuas no kuj tsis tshwj xeeb thiab xav tau kev kho kom haum rau ntau yam kev xav tau, xws li kev kho dej khib nyiab, kev kho dej haus thiab ntsuas cov ammonia hauv dej ntws. Cov electrodes xaiv ion feem ntau xav tau kev xoom thiab kev kho kom haum txhua hnub nrog cov tshuaj reagents.
Lub HONDE ammonia monitor zam cov teeb meem ntawm cov tshuaj ammonia ib txwm muaj los ntawm kev siv txoj hauv kev tshwj xeeb kiag li. Cov ammonia raug hloov mus rau hauv cov khoom siv monochloramine ruaj khov ntawm qhov concentration sib npaug rau qib ammonia thawj. Qhov concentration ntawm chloramine ces ntsuas siv lub sensor polarographic membrane nrog kev teb xaiv linear rau chloramine. Cov tshuaj tiv thaiv ua rau lub monitor zoo heev txawm tias nyob rau qib ammonia qis heev (ppb).
Cov tshuaj reagent yooj yim, tus nqi qis thiab siv tsawg. Yog li tus nqi ntawm kev muaj yog qis heev.
Cov tuam txhab dej loj hauv UK thiab qee lub chaw soj nstuam uas tau lees paub los ntawm Environment Agence twb siv cov neeg saib xyuas HONDE los saib xyuas cov dej ammonia hauv dej ntws. Lub tshuab ammonia tshiab no los ntawm Analytica Technologies muab cov neeg siv nrog lub monitor uas yooj yim rau kev khiav lag luam, pheej yig rau kev yuav khoom, qis khiav thiab tsis muaj kev cuam tshuam kev ntsuas.
