Izicelo ze-UV-C ze-LED kwi-Disinfection yamanzi

Iiteknoloji ezahlukeneyo zokunyanga amanzi kuquka Isifo samanzi e-UV  ziye zaphuhliswa ngenxa yokunyuka kwemfuno yamanzi okusela acocekileyo. Kwiminyaka yakutshanje, iteknoloji ye-LED ye-Ultraviolet-C (UV-C) ifumene umdla obalulekileyo kwizicelo ezinokuthi zisetyenziswe kunyango lwamanzi aphathwayo. Le teknoloji inenani leenzuzo ngaphezu kwezibane ze-UV eziqhelekileyo ezisekelwe kwi-mercury, kubandakanywa nokusebenza kakuhle kwamandla, iindleko eziphantsi zokusebenza, kunye nendawo encinci yokusingqongileyo. Eli nqaku libonelela ngesikhokelo esibanzi kwizicelo ze-UV-C ze-LED ekulungisweni kwamanzi okusela.

UV-C LED Technology

Imitha ye-UV-C luhlobo lwemitha ye-electromagnetic radiation enobude obusuka kuma-200 ukuya kuma-280 eenanomitha. Ngokususa i-DNA yeentsholongwane ezifana neebhaktheriya, iintsholongwane, kunye neprotozoa, iyasebenza kakhulu ekubulaleni iintsholongwane emanzini. Izibane ze-UV zesiNtu zivelisa ukukhanya kwe-UV-C kusetyenziswa umphunga wemekyuri. Izibane ezisekelwe kwi-Mercury zinemiqobo emininzi, kubandakanywa ukusetyenziswa kwamandla aphezulu, iingozi zokusingqongileyo, kunye nesidingo sokutshintshwa ngamaxesha athile.

Ngokwahlukileyo, itekhnoloji ye-UV-C ye-LED isebenzisa imathiriyeli ye-semiconductor ukuvelisa imitha ye-UV-C. Ii-LED zisebenza ngamandla kwaye zihlala ixesha elide kunezibane ze-UV eziqhelekileyo. Ukongeza, ezi LED azinamekyuri, nto leyo ezenza zithandeke ngakumbi kokusingqongileyo. Ukongeza, zinokuthi ziyilelwe ukuba zikhuphe ubude obuthile, ukuvumela ulawulo olukhulu kwinkqubo yokubulala iintsholongwane.

Ukusetyenziswa kwe-UV-C LEDs kunyango lwamanzi okusela

I-teknoloji ye-UV-C ye-LED inezicelo ezininzi kunyango lwamanzi okusela, kuquka:

Ukubulala iintsholongwane

Ukubulala iintsholongwane sesona sicelo sixhaphakileyo sobu buchwepheshe kulungiso lwamanzi okusela. Isebenza ngakumbi kunezinye Isifo samanzi e-UV Imitha ye-UV-C isebenza ngokugqwesileyo ekutshabalaliseni iDNA yeentsholongwane ezinje ngebhaktheriya, iintsholongwane, kunye neprotozoa, ibenza bangakwazi ukuzala kunye nokwenzakala. Imitha ye-UV-C ingena kwi-microorganisms cell membranes kwaye yonakalise iDNA yazo, ibathintele ekubeni baphindaphindeke kwaye basasaze izifo.

Imitha ye-UV-C ayivelisi i-disinfection by-products eyingozi (DBPs) kwaye ayitshintshi incasa, umbala, okanye ivumba lamanzi, ngokungafaniyo neklorine, eqhele ukusetyenziselwa ukubulala iintsholongwane emanzini. Imitha ye-UV-C isebenza ngokubonakalayo ngokuchasene ne-chlorine-resistant pathogens emanzini njengeCryptosporidium kunye ne-Giardia. Iinkqubo ze-UV-C ze-LED zinokuyilwa ukuhambisa idosi eyimfuneko yokubulala iintsholongwane emanzini.

I-TOC iyancipha

Itotali ye-organic carbon (TOC) yamanzi ngumlinganiselo womxholo wayo we-organic. Uxinzelelo oluphezulu lwe-TOC lunokubangela ukubunjwa kwe-DBPs, eyonakalisa impilo yabantu.
