Nyeoe Jeremane: Metsi a pompo a hlokahala bakeng sa ho sefa bakeng sa ho nooa ka kotloloho
Le hoja metsi a mangata a pompo linaheng tse tsoetseng pele a sireletsehile, boholo ba oona ha a joalo, joalo ka Jeremane. Taolo e sa lekaneng ea metsi a litšila a litoropong, indastering le temong e bolela hore metsi a nooang a batho ba limilione tse makholo a silafalitsoe ka tsela e kotsi kapa a silafalitsoe ke lik'hemik'hale.
Litšila tse ka bang teng metsing a mohloli li kenyelletsa:
Lintho tse silafatsang, tse kang livaerase le libaktheria, tse ka tsoang litsing tsa likhoerekhoere, tsamaiso ea likhoerekhoere, mesebetsi ea liphoofolo tsa temo le liphoofolo tse hlaha.
Lintho tse silafatsang, tse kang matsoai le tšepe, tse ka bang teng ka tlhaho kapa ka lebaka la ho phalla ha metsi a sefefo metseng ea litoropo, metsi a litšila a indasteri kapa a malapeng, tlhahiso ea oli le khase, merafo kapa temo.
Meriana e bolaeang likokoanyana le litlama, e ka tsoang mehloling e fapaneng e kang temo, metsi a likhohola a phallang litoropong, le lits'ebeliso tsa bolulo.
Lintho tse silafatsang tsa lik'hemik'hale tsa tlhaho, ho kenyelletsa le lik'hemik'hale tsa tlhaho le tse feto-fetohang, tse hlahisoang ke lits'ebetso tsa indasteri le tlhahiso ea peterole, hape li ka tsoa liteisheneng tsa khase, ho phalla ha metsi a sefefo sa litoropo le lits'ebetso tsa septic.
Litšila tsa mahlaseli a kotsi, tse ka bang teng ka tlhaho kapa tsa bakoa ke tlhahiso ea oli le khase le mesebetsi ea merafo.
Kahoo, ho molemo haholo ho hlomella sehloekisi sa metsi bakeng sa metsi a pompo ea hau e le metsi a hau a nooang ka kotloloho.
Litšilafatso tse tloaelehileng metsing a pompo
Tsena ke tse ling tsa lik'hemik'hale le litšila tse ka bakang mathata:
Likokoana-hloko (Baktheria le Likokoana-hloko)
Haeba u noa metsi a pompo a tala ka kotloloho ho tsoa selibeng se senyenyane sa thaba ho ka etsahala hore ebe o na le libaktheria tse kang coliform. Sena se tloaelehile ka ho feletseng 'me ha ho bonolo hore se u kulise ka tekanyo e nyenyane.
Leha ho le joalo, bakeng sa phepelo ea metsi a lipompo tsa sechaba, ho bohlokoa hore ho se be le coliform ho kenyelletsa e.coli.
Ka lehlohonolo, metsi a pompo linaheng tse tsoetseng pele a entsoe ka chlorine, chloramine kapa ozone ho bolaea likokoana-hloko tsohle. Linaheng tse ngata tse futsanehileng likokoana-hloko e ntse e le bothata bo boholo. Ho phaella tabeng ena ea khale le e sa hlokomeloe hantle litanka tsa metsi mehahong le li-filters tsa metsi li ka etsa hore libaktheria li hōle le ho silafatsa metsi a nooang a sebakeng seo.
Chlorine le chlorine by-products
Mokhoa o tloaelehileng oa ho bolaea likokoana-hloko o kenyelletsa mofuta o itseng oa chlorine kapa metsoako ea eona e kang chloramine kapa chlorine dioxide. Chlorine ke oxidant e matla e bolaeang ka potlako likokoana-hloko tse ngata tse kotsi. Kaha chlorine ke khase e chefo, ho na le kotsi ea ho lokolloa ho amanang le tšebeliso ea eona. Bothata bona bo qojoa ka tšebeliso ea sodium hypochlorite, e leng tharollo e batlang e le theko e tlaase e sebelisoang ka bleach ea malapa e ntšang chlorine ea mahala ha e qhibiliha metsing.
Maemo a chlorine ho fihla ho limiligrama tse 4 ka litara (likarolo tse 4 ho milione) a nkoa a bolokehile metsing a nooang. Mefuta eohle ea chlorine e sebelisoa haholo, ho sa tsotellehe mefokolo ea bona. Phello e 'ngoe ke hore chlorine e tsoang mohloling ofe kapa ofe e kopana le metsoako ea tlhaho ea tlhaho ka metsing ho etsa lihlahisoa tsa lik'hemik'hale tse ka bang kotsi. Lihlahisoa tsena, trihalomethanes (THMs) le haloacetic acid (HAAs), ka bobeli li na le kankere ka bongata 'me li laoloa ke United States Environmental Protection Agency (EPA), EU le WHO. Ho thehoa ha li-THM le li-haloacetic acid ho ka fokotsoa ka ho tlosoa ka katleho ha lintho tse ngata tse phelang metsing ka hohle kamoo ho ka khonehang pele chlorine e eketsoa. Le hoja chlorine e atleha ho bolaea libaktheria, e boetse e na le katleho e fokolang khahlanong le pathogenic protozoa e etsang li-cysts metsing a kang Giardia lamblia le Cryptosporidium.
OLANSI metsi a hloekisang a tla rarolla bothata bohle ba metsi a pompo ka holimo, ho netefatsa hore lelapa la Majeremane le ka noa metsi a phetseng hantle.
OLANSI e thehiloe ka 2009, moetsi ea nang le boiphihlelo bo fetang lilemo tse 10+. Re fektheri e hloahloa ea ho hloekisa metsi le mochini o fanang ka metsi, re fana ka litšebeletso tsa lefats'e tsa OEM le ODM. Ho fana ka potlako, theko ea tlhōlisano, boleng bo phahameng, le tšebeletso ea nako e telele ho bareki ba rona.
