Ingxaki yokunqongophala kwamanzi kunye nokunyuka kwembalela kunwenwa kwihlabathi liphela. Yeyona ngxaki inkulu nokusingqongileyo, kuba sifuna amanzi kuyo yonke into. Ngaphandle kwamanzi besingenakuphila.
Ukongeza kwingxaki yokunqongophala kwamanzi yenye ingxaki yokusingqongileyo ekwehlisa isixa samanzi akhoyo: Ungcoliseko lwamanzi. Ungcoliseko lwamanzi sesinye seziphumo eziphambili zomsebenzi wezemizi-mveliso. Ukusukela oko kwafika uguquko kwimizi-mveliso, ungcoliseko lwamanzi lonyuke ngokumangalisayo. Zonke iikhemikhali, i-petrochemical, amayeza, iinkampani zentsimbi kunye nezokukhupha zishiye umthwalo omkhulu onetyhefu kwimizimba yamanzi kwihlabathi liphela. Nangona kunjalo, amashumi amabini eminyaka itekhnoloji evela kwindalo enye iyindlela yokuphuma kule ngxaki. Sithini esi sisombululo?
I-Microalgae njengesisombululo kungcoliseko lwamanzi
Isisombululo ekunciphiseni iingxaki zongcoliseko lwamanzi silele ekusetyenzisweni kwe-algae ukuzonakalisa. Le teknoloji yavela ngaphezulu kweminyaka eli-17 eyadlulayo. Iprojekthi esebenzisa imicroalgae ukungcolisa amanzi ibizwa ngokuba yi-bioremediation. Kufunyenwe kubulelwa into yokuba nanini na kukho amanzi angcolileyo kwindalo, ii-microalgae ziyayiphendula loo nto, kuba zinako ukuguqula izinto ezinobuthi zibe zezinye ezingenatyhefu, ezinje ngeeproteni.
Ezi algae zahlukile kwinto esiyaziyo. Zizinto eziphilayo ezingafaniyo nezinye, azinangcambu okanye isiqu. Zincinci kakhulu kangangokuba zibonakala kuphela kwimicroscope. Ezi algae zikhona kwihlabathi liphela kwaye yi-30% kuphela yeentlobo ezinokubakho ezaziwayo.
Angcoliseka njani amanzi?
Ezi microalgae zisebenza njengohlobo lokucoca ulwelo. Banee-glucopolysaccharides kumphezulu wazo ezisebenza njenge-velcro ukubambisa iimolekyuli ezingcolisayo ezikhoyo emanzini. Njengoko i-microalgae isenza ezi zinto zingcolisayo, ijika ibe yi-biomass. Into encomekayo yeyokuba i-microalgae iyamelana neentsholongwane kwaye ayizibulali ezinye izinto esele zingene kwindalo eza kungenelela.
Oku kunokwenzeka ukuba ukwazi ukuthatha inyathelo ekunciphiseni kwamanzi akhoyo kwihlabathi kunye nokunciphisa iingxaki zamanzi.
Molo sithandwa.
Zeziphi iintlobo okanye iintlobo ezisebenza njengezinto eziphilayo.
