Litšila tse tsoang lits'ebetsong tsa ho qetela tsa tšepe hangata ke seretse (silt) se nang le litšepe tse qhibilihisitsoeng ka har'a maro.Ts'ebetso ea ho etsa tšepe ea tšepe, ho qeta tšepe le boto e hatisitsoeng ea potoloho (PCB) e hlahisa silt e ngata e nang le li-hydroxide tsa tšepe tse kang ferric hydroxide, magnesium hydroxide, nickel hydroxide, zinc hydroxide, copper hydroxide le aluminium hydroxide.Metsi a litšila a ho qeta ka tšepe a tlameha ho hloekisoa hore a ikamahanye le melaoana eohle e sebetsang ka lebaka la tšusumetso ea tikoloho le batho / liphoofolo tsa litšila tsena.
Liaparo tsa indasteri
Indasteri ea litšebeletso tsa masela ea khoebo e sebetsana le liaparo tse ngata selemo se seng le se seng, 'me liaparo tsena, lithaole, MATS ea fatše, joalo-joalo, li hlahisa metsi a litšila a tletseng oli, wadding, lehlabathe, grit, litšepe tse boima le metsoako ea lintho tse phelang e tlamehang ho phekoloa. pele ho phefumoloha.
Indasteri ea merafo
Mehatla ya morafo ke motswako wa metsi le majwe a matle a pshatlehileng a setseng ho tloswa ha diminerale tse tsepamisitsweng, tse kang kgauta kapa silifera, nakong ya tshebetso ya merafo.Ho lahleha ka katleho ha mesaletsa ea merafo ke phephetso e kholo bakeng sa lik'hamphani tsa merafo.Lithako ke molato oa tikoloho hammoho le phephetso e kholo ea litšenyehelo le monyetla oa ho fokotsa litšenyehelo tsa lipalangoang le tsa ho lahla.Merero e nepahetseng ea kalafo e ka felisoa matangoaneng a li-tailings.
Ho qhekella ha oli le khase
Metsi a litšila a tsoang ho cheka khase ea shale a nkoa e le litšila tse kotsi ebile a letsoai haholo.Ho feta moo, metsi a kopantsoeng le lik'hemik'hale tsa indasteri ka liente tsa Wells ho thusa ho cheka ho ne ho e-na le sodium e ngata, magnesium, tšepe, barium, strontium, manganese, methanol, chlorine, sulfate le lintho tse ling.Nakong ea ho cheka, lisebelisoa tsa radioactive tse hlahang ka tlhaho li khutlela holimo hammoho le metsi.Metsi a fracking a ka boela a ba le li-hydrocarbon, ho kenyelletsa le chefo e kang benzene, toluene, ethylbenzene le xylene e ka lokolloang nakong ea ho cheka.
Setsi sa ho hloekisa metsi / litšila
Sehlahisoa se seng sa lifeme tsa likhoerekhoere ke tlhahiso ea litšila tse nang le lintho tse ngata tse ka silafatsang.Esita le metsi a hloekisitsoeng ka chlorine a ka ba le lihlahisoa tse thibelang likokoana-hloko tse kang trihalomethane le haloacetic acid.Masalla a tiileng a tsoang litsing tsa ho hloekisa likhoerekhoere, tse bitsoang biosolids, li na le menontsha e tloaelehileng, empa hape li ka ba le litšepe tse boima le metsoako ea maiketsetso e fumanoang lihlahisoa tsa ntlo.
