    Iingenelo zemibhobho edibeneyo ejikelezayo kwimibhobho ephambili yokuhambisa amanzi:

    1. Amandla nokuqina okwandisiweyo:

    Itekhnoloji yokudibanisa i-spiral esetyenziswa kwezi mbhobho idala isakhiwo esiqhubekayo, esingenamthungo esinamandla aphezulu kunye nokumelana noxinzelelo oluphezulu lwangaphakathi nolwangaphandle. Ukongeza, i-spiral seams ezifakwa ngokuqinileyo zonyusa ukuthembeka kombhobho, zinciphisa umngcipheko wokuvuza okanye ukugqabhuka. Oku kuhlala ixesha elide kuqinisekisa ubomi benkonzo ende kwimibhobho yakho yamanzi, kunciphisa iindleko zokugcinwa kunye nokutshintshwa.

    2. Ukumelana nokugqwala:

    Imigca yamanzi ephambili ivezwa kwiimeko ezahlukeneyo zokusingqongileyo, kubandakanya ukufuma, iikhemikhali kunye nomhlaba. Iipayipi ezidityanisiweyo ezijikelezayo zihlala zenziwe ngezinto ezimelana nokugqwala ezifana nentsimbi engagqwaliyo, ukuqinisekisa ukhuseleko oluhle kakhulu kumhlwa, ukukhukuliseka, kunye nezinye iintlobo zokugqwala. Olu xhathiso lwandisa ubomi beepayipi, luthintela ukuwohloka kwaye lugcina umgangatho wamanzi uphezulu.

    3. Ukusebenza kakuhle kweendleko:

    Ukutyala imali kwiipayipi ezidityanisiweyo ezijikelezayoumbhobho wamanzi ophambiliszingabonakala ziyindlela engabizi kakhulu ekuhambeni kwexesha. Ulwakhiwo lwayo oluqinileyo kunye nokumelana nokugqwala kunciphisa amaxesha okulungiswa nokutshintshwa, ngaloo ndlela konga iindleko ezinkulu zolondolozo. Ukongeza, kulula ukuzifaka, zilula, kwaye zinciphisa isidingo senkxaso eyongezelelweyo, nto leyo eyenza zibe lukhetho olulula nolungabizi kakhulu kwiiprojekthi ezinkulu zombhobho.

    4. Ukuguquguquka kunye nokuguquguquka:

    Umbhobho odibeneyo ojikelezayo unika ukuguquguquka okuphezulu kunye nokuguquguquka kwiindlela zokusebenza zawo. Zingaveliswa ngobubanzi obahlukeneyo, ubude kunye nobukhulu, okuvumela ukuba zenziwe ngokwezifiso ukuhlangabezana neemfuno ezithile zeprojekthi. Oku kuguquguquka kuvumela ukuba zilungelelanise imihlaba eyahlukeneyo kunye neemeko ezahlukeneyo zomhlaba, nto leyo eyenza ukuba zibe lukhetho oluhle kakhulu kwimibhobho ephambili yokuhambisa amanzi kwiindawo zasezidolophini nasemaphandleni.

    5. Uzinzo lwendalo esingqongileyo:

    Ukongeza kwiingenelo zayo zokusebenza, iipayipi ezidityanisiweyo ezijikelezayo zikwanegalelo elihle ekuzinzeni kwendalo. Izinto ezisetyenziswa ekwakhiweni kwayo ziyaphinda zisetyenziswe, nto leyo enciphisa umonakalo wekhabhoni iyonke. Ukongeza, uyilo lwayo olungenamthungo lunciphisa ukulahleka kwamanzi ngenxa yokuvuza, ngaloo ndlela lukhusela esi sixhobo sibalulekileyo.

    a. Indlela yokususa ioksijini ichazwe ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha initrogen ngobuninzi obaneleyo ukubopha initrogen ekhoyo (umz. ubuncinci be-0,020% iyonke ye-Al okanye i-0,015% ye-Al enyibilikayo).

    b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukwakheka kweekhemikhali kubonisa umxholo opheleleyo we-Al ongama-0,020% kunye nomlinganiselo ophantsi we-Al/N oyi-2:1, okanye ukuba kukho ezinye izinto ezaneleyo zokubopha i-N. Izinto zokubopha i-N mazirekhodwe kuXwebhu loHlolo.

    Ukuququmbela:

    Ukuqinisekisa ukusebenza kakuhle nokuqina kwemibhobho yakho yamanzi ephambili kubalulekile ukuqinisekisa ukufumaneka kwamanzi okuthembekileyo. Ukusetyenziswa kwemibhobho edibeneyo ejikelezayo kweziumbhobho imigcaInika iingenelo ezininzi, kuquka ukomelela okwandileyo, ukumelana nokugqwala, ukusebenza kakuhle kweendleko, ukuguquguquka kunye nokuzinza kokusingqongileyo. Njengoko sisebenzela ukwakha iziseko zamanzi eziqinileyo nezisebenzayo, ukutyala imali kubuchwepheshe obuphambili obufana nombhobho odibeneyo ojikelezayo kubalulekile.
