Mokhoa o akaretsang oa kalafo ea metsi o sebelisa coagulation, sedimentation, filtration le lits'ebetso tse ling. Ts'ebetso tsena li ka hloekisa mohloli oa metsi, empa mohloli oa metsi o boetse o na le lintho tse phelang le likokoana-hloko. Hajoale, mekhoa ea kalafo ea metsi le ho thibela likokoana-hloko e kenyelletsa khase ea chlorine, phofo e soeufatsang, sodium hypochlorite, chloramine, lebone la ultraviolet le ozone. Mokhoa o mong le o mong oa ho thibela likokoana-hloko o na le litšobotsi tse fapaneng.
Chlorine disinfection e ntle, empa e hlahisa likokoana-hloko. Phofo e soeufatsang le hypochlorite ea sodium li bonolo ho bola, li hloka botsitso, chloramine ea sterilization e mpe, UV disinfection e na le meeli, hajoale ozone ke mokhoa o loketseng oa ho bolaea mafu.
Joaloka ts'ebetso e tebileng ea kalafo ea metsi, ozone e na le phello e matla ea baktheria. E ka bolaea mefuta e mengata ea likokoana-hloko le likokoana-hloko, 'me ea bolaea likokoana-hloko tse kotsi tse kang Escherichia coli, Staphylococcus aureus, spores ea baktheria, Aspergillus niger le tomoso.
Ho fapana le mekhoa e meng ea ho thibela likokoana-hloko, ozone e itšoara ka lisele tsa baktheria, e kenella kahare ho lisele, e sebetsa ka taba e tšoeu le lipopolysaccharide, mme e fetola ho kenella ha lisele, e lebisang lefung la sele. Ka hona, ozone e ka bolaea libaktheria ka kotloloho. Ozone e na le monyetla o moholo oa hore ha ho na masala. Kamora ho bolaoa ka tšoaetso, ozone e senyeha ho ba oksijene, e ke keng ea baka tšilafalo ea bobeli.
Melemo ea ozone e ea kalafo ea metsi:
1. E na le phello e matla ea ho bolaea likokoana-hloko tse fapaneng tsa pathogenic;
2, ka potlako disinfection, ka hang-hang bola lintho tse phelang ka metsing;
3. Ozone e na le mefuta e mengata e fapaneng ea ho ikamahanya le maemo le matla a matla a oxidation;
4, ha ho na tšilafalo ea bobeli, ho bola ha ozone le ho bola ha oksijene;
5, e ke ke ea hlahisa li-product tsa trihalomethane le tse ling tsa chlorine disinfection;
6. Ha e ntse e bolaea likokoana-hloko, e ka ntlafatsa semelo sa metsi mme ea hlahisa tšilafalo e tlase ea lik'hemik'hale.
7. Ha e bapisoa le mekhoa e meng ea ho thibela likokoana-hloko, potoloho ea ozone ea ho thibela likokoana-hloko e khutšoanyane ebile e baballa chelete.
