Ukwenziwa inzala kubhekiselele ekusetyenzisweni kwezinto ezomeleleyo zomzimba kunye neekhemikhali ukwenza zonke iintsholongwane ngaphakathi nangaphandle kwayo nayiphi na into ziphulukane nokukhula kunye nokukwazi ukuzala ngonaphakade.Iindlela ezixhaphakileyo zokuvala inzala ziquka ukuvala inzala kwikhemikhali, ukuvala inzala ngemitha, ukuvala ubushushu obomileyo, ukuvala ubushushu obumanzi kunye nesihluzo.Iindlela ezahlukeneyo zinokusetyenziswa ngokweemfuno ezahlukeneyo.Umzekelo, indawo ephakathi ivalwa bubushushu obufumileyo, kwaye umoya ucolwa ngokucoca.
Isibane sentsimbi ye germicidal sisisibane esinoxinzelelo oluphantsi lwemercury.Isibane esiphantsi soxinzelelo lwe-mercury sikhupha ukukhanya kwe-ultraviolet ngokuvuyiswa nguxinzelelo oluphantsi lwe-mercury vapor (<10-2Pa).Kukho imigca emibini engundoqo yokukhupha i-spectral: enye yi-253.7nm wavelength;enye yi-185nm wavelength, omabini angamehlo e-ultraviolet imitha yelanga engabonakaliyo.Isibane se-germicidal yensimbi engenastainless akufuneki ukuba siguqulwe sibe kukukhanya okubonakalayo, kwaye ubude be-253.7nm bunokudlala isiphumo esihle sokuvala inzala.Oku kungenxa yokuba iiseli zinesiqhelo kwi-spectrum yokufunxa amaza okukhanya.Imitha ye-Ultraviolet kwi-250 ~ 270nm inokufunxeka okukhulu kwaye iyafunxa.Ukukhanya kwe-ultraviolet ngokwenene kusebenza kwizinto zofuzo zeseli, eyi-DNA.Idlala uhlobo lwempembelelo ye-actinic.Amandla eefoton ze-ultraviolet afunxwa zizibini ezisisiseko kwi-DNA, ebangela ukuba izinto zofuzo ziguquke, zibangele ukuba iibhaktheriya zife ngokukhawuleza okanye zingakwazi ukuvelisa inzala yazo.Ukufezekisa injongo yokuvala inzala.
