Ukugquma kwamanzi angaphezulu kwamanzi
Yintoni i-turbidity? I-turbidity ibhekisa kwiqondo lothintelo lwesisombululo kwindlela yokukhanya, ebandakanya ukusasazwa kokukhanya ngezinto ezimisiweyo kunye nokufunxwa kokukhanya ngamamolekyuli e-solute. I-turbidity yiparameter echaza inani lamasuntswana amisiweyo kwi-li...Funda ngokugqithisileyo -
Yintoni i-chlorine eseleyo emanzini kunye nendlela yokuyifumanisa?
Ingqikelelo ye-chlorine eshiyekileyo I-chlorine eshiyekileyo sisixa seklorin ekhoyo eseleyo emanzini emva kokuba amanzi ekloriniwe kwaye abulawa iintsholongwane. Le nxalenye yeklorini yongezwa ngexesha lenkqubo yokunyanga amanzi ukubulala ibhaktheriya, i-microorganisms, izinto eziphilayo kunye ne-inorganic matt ...Funda ngokugqithisileyo -
Isishwankathelo seendlela zokuhlalutya kwizalathi ezilishumi elinesithathu ezisisiseko zokucocwa kwamanzi amdaka
Uhlalutyo kwizityalo zokucocwa kwamanzi amdaka yindlela ebaluleke kakhulu yokusebenza. Iziphumo zohlalutyo zisisiseko sokulawulwa kwamanzi amdaka. Ngoko ke, ukuchaneka kohlalutyo kufuna kakhulu. Ukuchaneka kwamaxabiso ohlalutyo kufuneka kuqinisekiswe ukuqinisekisa ukuba ukusebenza okuqhelekileyo kwenkqubo ku ...Funda ngokugqithisileyo -
Intshayelelo ye-BOD5 yokuhlaziya kunye nobungozi be-BOD ephezulu
Imitha ye-BOD sisixhobo esisetyenziselwa ukufumanisa ungcoliseko lwendalo kwimizimba yamanzi. Iimitha ze-BOD zisebenzisa ubungakanani beoksijini esetyenziswa zizidalwa ukudiliza izinto eziphilayo ukuvavanya umgangatho wamanzi. Umgaqo wemitha ye-BOD usekelwe kwinkqubo yokubola ukungcola kwezinto eziphilayo emanzini nge-bac...Funda ngokugqithisileyo -
