Izisombululo zeZisombululo zeZityalo zokucocwa kwaManzi ezinexabiso elisebenzayo kwiifektri: Yonga imali kwaye uhlale uthobela

Imigca yemveliso kuwo wonke amashishini ijongene noxinzelelo olwandayo lokunyanga amanzi amdaka ngokufanelekileyo ngeli lixa iindleko ziphantsi kwaye zihlala zithobela ulawulo lokusingqongileyo. Ukwenza kube nexabiso eliphantsi Ucoceko lokucoca amanzi amdaka Amalungiselelo abalulekile kumaziko emizi-mveliso ajonge ukwandisa ukusebenza kwawo kwaye agcine amawonga ezoqoqosho. Eli nqaku liphanda i-commonsense kunye nemigaqo yokulawula amanzi amdaka afanelekileyo anokunceda izityalo zokuvelisa zonge imali ngelixa indibano ifuna imilinganiselo yokuthotyelwa. Ukusuka kukhetho lonyango oluphantsi kweendleko eziphantsi ukuya kwizikhokelo zohlobo oluhlukeneyo kunye neendlela zokuphucula, siza kujonga ukuba inguqulelo ephucukileyo kunye nocwangciso olunolwazi olunokuwatshintsha njani amanzi amdaka ukusuka kumthwalo ukuya kwithuba lemveliso kunye nolawulo lokusingqongileyo.

Zeziphi iindlela zokucocwa kwamanzi amdaka ngexabiso eliphantsi ezidla ngokusetyenziswa ziifektri?

Iifektri zineendlela ezininzi zokonga iindleko zokucocwa kwamanzi amdaka ezinokunciphisa kakhulu iindleko zokusebenza ngaphandle kokubeka esichengeni kumgangatho wonyango. Ezinye zeendlela eziqhelekileyo ziquka:

Ukucolwa kwe-Anaerobic

I-Anaerobic assimilation yinkqubo yendalo eqhekeza into yendalo ngokungabikho kwe-oxygen. Esi sicwangciso siphumelele ngakumbi kumanzi amdaka endalo aphezulu asuka kumashishini ezondla kunye nokuhlaziya. Umqheba hayi njengokuba uphatha amanzi amdaka kodwa uvelisa igesi ephilayo, enokuthi isetyenziswe njengomthombo wamandla ahlaziyekayo, ukuhlawula iindleko zonyango.

Imigxobhozo eyakhiweyo
