Ukuthuthukiswa okuyimpumelelo kweprosesa lamanzi kuzothatha indawo yemishini yokuhlanza amanzi kusetshenziswa indlela yamakhemikhali kanye nendlela yokuhlunga.Kuphephile futhi kulula ukuyisebenzisa, ngokuyisisekelo ngaphandle kwezindleko, futhi umphumela usufinyelele inkomba efanelekile.
Ngemuva kokufakwa nokusetshenziswa epayipini, lingabulala inzalo, libulale ulwelwe, lishintshe ikhwalithi yamanzi futhi lisuse isikhunta sangempela epayipini.(i-organic scaling).
