Sengisho nje,imfucumfucuibhekisela kuimfucumfucukwamanzi.Ngokuqondile, kusho ukuthi umzimba wamanzi uqukethe izinto ezimisiwe, futhi lezi
izinto ezimisiwe zizothikazwa lapho ukukhanya kudlula.Leli zinga lokuvinjelwa libizwa ngokuthiimfucumfucuinani.Okuqinile okumisiwekanye nama-colloids
njengenhlabathi, udaka, i-organic matter, i-inorganic matter, kanye ne-plankton emanzini kungenza amanzi aguge futhi alethe udaka oluthile.
Ngokusho kweukuhlaziywa kwekhwalithi yamanzi, iimfucumfucueyakhiwe ngo-1 mg SiO2 emanzini ayi-1L iyiZinga elilodwaimfucumfucuiyunithi, ebizwa ngokuthi yi-1 degree.
Ngokuvamile, ukuphakama kwe-imfucumfucu, ikhambi eliguquguqukayo.
Umgomo wokulinganisa we-turbidity:
Ukukhanya okuhambisanayo kusakazeka oketshezini olubonisa ngale.Uma zingekho izinhlayiya ezimisiwe oketshezini, ugongolo ngeke lushintshe indlela lapho luhamba
emgqeni oqondile;noma cha).Lokhu kwakha lokho okwaziwa ngokuthi ukukhanya okuhlakazekile.Izinhlayiya eziningi (eziphezuluimfucumfucu) kubi kakhulu ukuhlakazeka kokukhanya.I-Turbidity
kukalwa ngensimbi ebizwa ngokuthi i-nephelometer.I-nephelometer ithumela ukukhanya engxenyeni yesampula futhi ikala ukuthi kungakanani ukukhanya okuhlakazeke ngakho
izinhlayiya emanzini nge-engeli engu-90° ekukhanyeni kwesigameko.Le ndlela yokulinganisa ukukhanya okuhlakazekile ibizwa ngokuthi indlela yokuhlakaza.Noma yiliphi iqinisoimfucumfucukumele
kukalwe ngale ndlela.Iimitha ye-turbidityifaneleka kokubili izilinganiso zensimu nezaselabhorethri, kanye nokuqapha okuqhubekayo ubusuku nemini.Ama-turbidimeters
ingasethwa ukuze ikhale i-alamu uma ikalwaimfucumfucuamanani eqa amazinga okuphepha.
Izindlela zokulinganisa:
1. I-Turbidityingalinganiswa ngendlela ye-nephelometric noma indlela yokukhanya ehlakazekile.E-China, i-turbidimetry ngokuvamile isetshenziselwa ukuzimisela.Isampula lamanzi liyaqhathaniswa
ngeimfucumfucuisisombululo esijwayelekile esilungiselelwe nge-kaolin, kanye neimfucumfucuAlikho phezulu, futhi kubekwe ukuthi i-1 mg ye-silicon dioxide ilitha elilodwa lamanzi acwecwe
aimfucumfucu iyunithi.NgobaIzindlela zokulinganisa ezihlukene noma izinto ezijwayelekile ezihlukile, amanani okulinganisa uthuthuva awahambisani ngempela.Izinga le
imfucumfucungokuvamileangekechaza ngokuqondile izinga lokungcoliswa kwezinga lamanzi, kodwa ukwanda kweimfucumfucuokubangelwa ukuphila komuntu kanye nendle yezimboni kubonisa
ukuthi izinga lamanzi liye lehla.
2. I-Turbiditykungabuye kukalwa nge-turbidimeter.I-nephelometer ithumela ukukhanya engxenyeni yesampula futhi ikala ukuthi kungakanani ukukhanya okuhlakazwe yizinhlayiya emanzini.
ngo 90°i-angle ekukhanyeni kwesigameko.Le ndlela yokulinganisa ukukhanya okuhlakaziwe ibizwa ngokuthi indlela yokuhlakaza.Noma yiliphi iqinisoimfucumfucukufanele kulinganiswe ngale ndlela.Iimitha ye-turbiditykuyinto
kufanelekile kokubiliizilinganiso zensimu nezaselabhorethri, kanye nokuqapha okuqhubekayo ubusuku nemini.Ama-turbidimetersingasethwa ukuze ikhale i-alamu uma ikalwa
imfucumfucu amanani eqa amazinga okuphepha.
3. I-Turbiditykungase futhi kulinganiswe ngokusebenzisa i-colorimeter noma i-spectrophotometer ukukala izinga lokuncishiswa kokukhanya okudlulisiwe okubangelwa ukuvinjelwa.
kweizinhlayiya kuisampula.Kodwa-ke, ama-ejensi alawulayo awakuboni ukufaneleka kwale ndlela, futhi ayihlangabezani nencazelo ye-American Public Health Association yokuthi
imfucumfucu.
4. Isilinganiso sokudlulisa ukukhanya sithikamezeka kalula njengokumuncwa kombala noma ukumuncwa kwezinhlayiyana.Ngaphezu kwalokho, kwakungekho ukuhlobana phakathi kokudluliswa kokukhanya nemiphumela elinganiswa ngezilinganiso zokukhanya ezihlakazekile.Noma kunjalo, kwesinye isikhathi izilinganiso ze-colorimeter ne-spectrophotometer zingasetshenziswa ukunquma ubukhuluimfucumfucuezinhlelweni zokuhlanza amanzi noma ukulawula inqubo.
