Ikhwalithi yamanzi omfula ihlolwa yi-Environment Agency ngohlelo lwe-General Quality Assessment (GQA) futhi kubalulekile ukuthi amakhemikhali angaba yingozi emfuleni alawulwe. I-Amonia iyisakhi esibalulekile sezitshalo kanye nolwelwe oluhlala emanzini omfula. Kodwa-ke, lapho izinga lokushisa lomfula lishintsha, i-ammonia ene-ion ishintsha ibe yigesi ye-ammonia engeyona i-ion. Lokhu kuyabulala izinhlanzi nezinye izinto eziphilayo zasemanzini emfuleni, ngakho-ke kubalulekile ukuqapha njalo amazinga e-ammonia.
Ikhwalithi yamanzi ibalulekile nasezitshalweni zokuhlanza amanzi ezisebenzisa amanzi omfula njengomthombo wazo. Amazinga aphezulu e-ammonia emanzini angabangela izinkinga ezinkulu enkambisweni yokubulala amagciwane. Ngokulinganisa ngempumelelo amazinga e-ammonia emanzini omfula endaweni yokungena yesitshalo sokuhlanza amanzi, inhlangano iyakwazi ukuvikela ukunikezwa kokungena. Kwezinye izinhlelo zokusebenza, indawo yokungena ingavalwa lapho amazinga e-ammonia efinyelela amazinga aphezulu ngendlela engamukeleki.
Amasu okuqapha i-ammonia amanje ayabiza futhi ayinkimbinkimbi, asebenzisa ama-electrode akhetha ama-ion kanye nama-reagent abizayo, anobuthi futhi kunzima ukuwaphatha. Lawa ma-monitha nawo awacacisiwe futhi adinga ukulinganiswa okuqhubekayo ukuze avumelane nezidingo ezahlukene, njengokwelashwa kwamanzi angcolile, ukwelashwa kwamanzi okuphuza kanye nokulinganisa amazinga e-ammonia emanzini omfula. Ama-electrode akhetha ama-ion ngokuvamile adinga ukulinganisa nsuku zonke kanye nokulinganiswa ngama-reagent.
I-monitor ye-ammonia ye-HONDE igwema izinselele zama-monitor e-ammonia endabuko ngokusebenzisa indlela eyingqayizivele ngokuphelele. I-ammonia iguqulwa ibe yi-monochloramine compound ezinzile ekugxilweni okulingana nezinga lokuqala le-ammonia. Ukugxilwa kwe-chloramine kwabe sekulinganiswa kusetshenziswa inzwa ye-polaragraphic membrane enempendulo eqondile ekhethiwe ku-chloramine. I-chemistry yokusabela inikeza i-monitor ukuzwela okuhle kakhulu ngisho nasemazingeni aphansi kakhulu e-ammonia (ppb).
I-reagent ilula, intengo iphansi futhi izinga lokusetshenziswa liphansi. Ngakho-ke izindleko zobunikazi ziphansi kakhulu.
Izinkampani ezinkulu zamanzi zase-UK kanye namanye amalabhorethri agunyazwe yi-Environment Agence asevele esebenzisa ama-monitor e-HONDE ukuqapha ngempumelelo amazinga e-ammonia emanzini omfula. Lolu hlelo olusha lwe-ammonia oluvela ku-Analytica Technologies lunikeza abasebenzisi i-monitor elula ukuyisebenzisa, engabizi ukuyithenga, ephansi ukuyisebenzisa futhi engenakho ukuphazamiseka kokulinganisa.
