E le ho lefa tšehetso ea bareki ba bacha le ba khale, khamphani ea rona e tla qala ketsahalo ea theolelo ea Keresemese ea khoeli e le 'ngoe kajeno, 'me lihlahisoa tsohle tsa k'hamphani ea rona li tla theoleloa ho 10%. Haeba u na le thahasello, ka kopo ikopanye le 'na.
Ha re tsebiseng bohle ka bokhutšoanyane lihlahisoa tsa rona tsa metsi a hloekileng. Lihlahisoa tsa rona tse ka sehloohong ke mefuta e felletseng ea lik'hemik'hale tsa kalafo ea likhoerekhoere, lihlahisoa tse ka sehloohong li kenyelletsa:Moemeli oa ho Tlosa 'Mala Metsing、Poly DADMAC、Polyacrylamide、 Polyamine,PolyAluminium Chloridele lihlahisoa tse ling.
Lik'hemik'hale tsa kalafo ea metsi li ka aroloa ka mekhahlelo e meraro:
1. Lik'hemik'hale tsa kalafo ea likhoerekhoere
2. Lik'hemik'hale tsa kalafo ea metsi tse potolohang indastering
3. moemeli oa karohano ea oli le metsi
Likarolo tsa lik'hemik'hale tse ncha tsa kalafo ea metsi
1. Lebelo la karabelo le potlakile, 'me ho nka halofo ea hora ho isa lihora tse' maloa feela ho hloekisa metsi a litšila a tloaelehileng a indasteri.
2. E na le ditlamorao tse fapaneng hodima ditshila tsa tlhaho, mme e na le phello e ntle ya ho senyeha ha dintho tsa tlhaho tse thata ho di senya.
3. Ts'ebetso e bonolo, matsete a manyane, bophelo ba ts'ebeletso bo bolelele, ts'ebetso le tlhokomelo li bonolo, phello ea kalafo e loketse, 'me reagent ea micro-electrolysis e sebelisoang nakong ea kalafo e nyane.
4. Kamora hore metsi a litšila a phekoloe ka micro-electrolysis, li-ion tsa pele tsa ferrous kapa tsa tšepe li tla thehoa ka metsing, e leng se nang le phello e betere ea ho hoama ho feta li-coagulant tse tloaelehileng. Ha ho hlokahale hore ho eketsoe li-coagulant tse kang letsoai la tšepe, 'me sekhahla sa ho tlosoa ha COD se phahame, 'me se ke ke sa baka tšilafalo ea bobeli metsing.
5. E na le phello e ntle ea ho hoama, e ka tlosa chroma le COD ka katleho, 'me e ntlafatsa haholo ho bola ha metsi a litšila.
Setlhare sa tlhaho sa kalafo ea likhoerekhoere tsa liminerale se na le litšobotsi tse hlano: ho monya metsi, phapanyetsano ea li-ion, ho petsoha ha catalytic, phetoho ea lik'hemik'hale le monono oa 'mele. Melemo ea ts'ebeliso:
(1) Molemo oa bohlokoa ka ho fetisisa ke hore e ka phekola mefuta eohle ea likhoerekhoere tse thata ho li phekola, haholo-holo likhoerekhoere tse chefo;
(2) Ho ka tlosoa karolo e nyenyane ea lintho tse phaphametseng;
(3) Ho phaphamala ka potlako le lebelo la ho senyeha ha mobu, mongobo o tlase oa mobu, ho ba le bongata bo phahameng, ho felloa ke metsi hantle, le kalafo e bonolo ea ho sefa;
(4) Mehaho le mekhoa ea ho hloekisa likhoerekhoere li bonolo, li bonolo ho li sebelisa, e leng se fokotsang haholo matsete a hang feela kahong ea projeke, 'me litšenyehelo tsa ts'ebetso ha li holimo;

Indastering ea kalafo ea metsi, ha se feela mefuta e fapaneng ea lisebelisoa tsa kalafo ea metsi e sebelisoang haholo, lik'hemik'hale tsa kalafo ea metsi le tsona li etsa menehelo e meholo liindastering tse fapaneng. Lik'hemik'hale tsa kalafo ea metsi li kenyelletsa lithibela-mafome le sekala, li-flocculant, li-reducer, li-bactericides, li-catalyst, li-cleaner agents, jj., tseo e 'ngoe le e 'ngoe ea tsona e nang le mesebetsi le litšobotsi tsa eona.
