Inkinga yokushoda kwamanzi nesomiso esandayo iyasabalala emhlabeni wonke. Kuyinkinga enkulu futhi enkulu yezemvelo, ngoba sidinga amanzi cishe kukho konke. Ngaphandle kwamanzi besingeke siphile.
Kungezwe enkingeni yokushoda kwamanzi kungenye inkinga yemvelo ephinde inciphise inani lamanzi atholakalayo: Ukungcoliswa kwamanzi. Ukungcoliswa kwamanzi kungenye yemiphumela emikhulu yemisebenzi yezimboni. Kusukela ekuguqulweni kwezimboni, ukungcoliswa kwamanzi kuye kwanda kakhulu. Zonke izinkampani zamakhemikhali, zepetrochemical, ezemithi, ezensimbi nezikhiqizayo zishiye umthwalo omkhulu onobuthi emzimbeni wamanzi emhlabeni jikelele. Kodwa-ke, sekuyiminyaka engamashumi amabili ubuchwepheshe obuvela kohlobo olufanayo buyindlela yokuphuma kule nkinga. Liyini leli khambi?
I-Microalgae njengesixazululo sokungcola kwamanzi
Isixazululo sokunciphisa izinkinga zokungcola kwamanzi silele ekusetshenzisweni kwe-algae ukuze kungcoliswe zona. Lobu buchwepheshe buvele eminyakeni engaphezu kwengu-17 edlule. Iphrojekthi esebenzisa ama-microalgae ukonakalisa amanzi ibizwa ngokuthi yi-bioremediation. Kutholwe sibonga iqiniso lokuthi noma nini lapho kunamanzi angcolile ku-ecosystem, ama-microalgae ayaphendula kulokho, ngoba anamandla okuguqula izinto ezinobuthi zibe ezinye ezingezona ezinobuthi, njengamaprotheni.
Lawa ma-algae ahlukile kulokho esikwaziyo. Ziyizinto eziphilayo ezinama-unicellular, azinampande noma isiqu. Mancane kakhulu kangangokuba abonakala kuphela ngaphansi kwesibonakhulu. Lawa ma-algae akhona emhlabeni wonke futhi angama-30% kuphela ezinhlobo ezingaba khona ezaziwayo.
Amanzi angcoliswa kanjani?
Lawa ma-microalgae asebenza njengohlobo lokuhlunga. Banobuso babo kukhona ama-glucopolysaccharides asebenza njenge-velcro ukubamba ama-molecule angcolisayo akhona emanzini. Njengoba i-microalgae icubungula lokhu kungcola, iyiguqula ibe yi-biomass. Okuncomekayo ukuthi ama-microalgae amelana kakhulu namabhaktheriya futhi awabulali ezinye izidalwa esezivele zihlala ezintweni ezizongenelela.
Lokhu kungenzeka ukuthi ukwazi ukuthatha igxathu ekunciphisweni kwamanzi akhona emhlabeni nokunciphisa izinkinga zamanzi.
Sawubona Sthandwa.
okuyizizukulwane noma izinhlobo ezisebenza njengama-bioremediators.
