Ha re ke re tsebiseng lihlahisoa tsa rona tsa cleanwat ka bokhutšoanyane ho motho e mong le e mong.Lihlahisoa tsa rona tse ka sehloohong ke mefuta e mengata ea lik'hemik'hale tsa likhoerekhoere, lihlahisoa tse kholo li kenyelletsa:Metsi Decoloring Agent,Poly DDMAC,PolyacrylamidePolyamine,PolyAluminium Chloridele lihlahisoa tse ling.
Lik'hemik'hale tse hloekisang metsi li ka aroloa ka mekhahlelo e meraro:
1. Lik'hemik'hale tsa ho hloekisa likhoerekhoere
2. Lik'hemik'hale tsa phekolo ea metsi tse potolohang indastering
3. moemeli oa karohano ea metsi a oli
Likarolo tsa lik'hemik'hale tse ncha tsa ho hloekisa metsi
1. Lebelo la karabelo le potlakile, 'me ho nka halofo ea hora ho isa ho lihora tse' maloa feela ho hloekisa metsi a litšila a tloaelehileng a indasteri.
2. E na le mefuta e mengata ea liphello ho litšila tse phelang, 'me e na le phello e ntle ea ho senya lintho tse thata ho senya lintho tse phelang.
3. Mokhoa ona o bonolo, matsete a manyenyane, bophelo ba tšebeletso bo bolelele, ts'ebetso le tlhokomelo li bonolo, phello ea phekolo e loketse, 'me reagent ea micro-electrolysis e sebelisoang nakong ea phekolo e fokotseha.
4. Ka mor'a hore metsi a litšila a tšoaroe ke micro-electrolysis, li-ion tsa pele tsa ferrous kapa tšepe li tla thehoa metsing, tse nang le phello e ntle ea ho kopanya ho feta li-coagulants tse tloaelehileng.Ha ho na tlhoko ea ho eketsa li-coagulants tse kang matsoai a tšepe, 'me sekhahla sa ho tlosoa ha COD se phahame,' me E ke ke ea baka tšilafalo ea bobeli metsing.
