Mehloli e Tloaelehileng ea Lerōle le Khomarelang
Seretse se khomarelang hangata se hlaha liindastering tse kang:
Mabaka a Bohlokoa
Liprotheine, mafura le lik'habohaedreite li eketsa ho teteana ha seretse.
Lintho tse ngata tse tsoang kantle ho polymeric (EPS) tse hlahisoang ke libaktheria li etsa matrix e khomarelang.
Li-flocculant tse sa lekaneng kapa tse sa tsamaellaneng li lebisa ho li-floc tse fokolang kapa tse thellang haholo.
Likaroloana tsa seretse tse nang le tjhaja e sa lokelang hodima metsi di thibela ho kopana ho sebetsang hantle.
Hobaneng ha seretse se khomarelang e le bothata
Seretse se khomarelang se ka ama ts'ebetso ea kalafo ea metsi a litšila hampe:
- Bokgoni ba ho Fokotsa ho Ntša Metsi Seretse se boloka metsi a mangata, e leng se fellang ka: Ho fokotsa dikahare tsa dikuku tse tiileng, ho eketseha ha bongata ba seretse, le ditjeo tse hodimo tsa ho lahla.

Qetello
Seretse se khomarelang ke bothata bo rarahaneng empa bo ka rarolloang kalafong ea metsi a litšila. Ka ts'ebeliso e nepahetseng ea Polyacrylamide (PAM), liindasteri li ka ntlafatsa haholo ts'ebetso ea ho tlosa metsi a litšila, tsa fokotsa litšenyehelo tsa ts'ebetso, le ho ntlafatsa ts'ebetso ea sistimi ka kakaretso.
Senotlolo se ho:
- Ho utloisisa litšobotsi tsa seretse
- Ho khetha mofuta o nepahetseng oa PAM
- Ho ntlafatsa tekanyo le ts'ebeliso
- Ho beha leihlo le ho lokisa ts'ebetso ka ho tsoelang pele
Ka ho kenya tshebetsong maano ana, dibaka tsa kalafo ya metsi a ditshila di ka fetola seretse se kgomarelang, se thata ho se tshwara hore e be tlhahiso e laolehang le e theko e tlase.
Haeba o na le bothata ba ho tlosa metsi a mangata a seretse, re fana ka:
- Tšehetso ea teko ea nkho ea mahala
- Litharollo tsa polyacrylamide tse ikhethileng
- Phepelo e tsitsitseng bakeng sa tšebelisano-'moho ea nako e telele
ho fumana tharollo e etselitsoeng uena le ho ntlafatsa katleho ea kalafo ea seretse sa hao.
