Metsi ke mohloli oa bophelo, re ke ke ra phela ntle le metsi, leha ho le joalo, ka lebaka la tsoelo-pele e feteletseng ea batho le tšilafalo ea mehloli ea metsi, libaka tse ngata li tobane le khaello e tebileng ea metsi le ho theoha ha boleng ba metsi. Ho rarolla mathata ana, bo-rasaense ba bangata le baenjiniere ba inehela ho etsa lipatlisiso le nts'etsopele ea mahlale a ho hloekisa metsi. Har'a bona, Polyaluminium Chloride (PAC), e le moemeli oa bohlokoa oa ho hloekisa metsi, e sebelisoa haholo tšimong ea ho hloekisa metsi le ho hloekisa likhoerekhoere.
Mosebetsi
Ketso ea PAC e finyelloa ka likarolo tse 'ne tsa sehlahisoa sa eona sa hydrolysis se hatelitsoeng, ho se nke lehlakore ha motlakase, ho ts'oara marang-rang, le borokho ba adsorption.
E potlakisa le ho sefa ntho e ka tšeloang ke oxidizer ho baka COD, ka hona ho fokotsa COD, le pula e nang le li-particulate matter.PAC ke sehlahisoa se bolokehileng, se bolokang tikoloho, le se sebetsang hantle sa ho hloekisa metsi a litšila. Ho ke ke ha feela ka katleho ho fokotsa mahloriso a lintho tse phelang, liminerale le likokoana-hloko ka likhoerekhoere, empa hape ka fokotsa chromaticity le turbidity ea likhoerekhoere, ka katleho fokotsa tšilafalo, ntlafatsa monko oa likhoerekhoere, fokotsa acidity le alkalinity ea likhoerekhoere, e le hore ka katleho ho ntlafatsa tšilafalo ea likhoerekhoere. PAC ke tlatsetso e sebetsang bakeng sa ho hloekisa likhoerekhoere, e nang le karolo ea bohlokoa ho hloekisa likhoerekhoere.
Litšobotsi
PAC ke inorganic polymer coagulant. E ka thefula likaroloana tse ntle tse emisitsoeng le li-ion tsa colloidal metsing, aggregate, flocculate, coagulate le precipitate ka compression ea double layer, adsorption le motlakase neutralization, adsorption le bridging, le precipitate catching net, joalo-joalo, e le ho finyella tlhoekiso le melemo e meng ea phekolo: PAC e na le melemo e mengata. mefuta e mengata ea lisebelisoa le ho ikamahanya le mefuta e mengata ea metsi.Ho bonolo ho theha palesa e kholo ea alum ka potlako 'me e na le ts'ebetso e ntle ea pula. E na le mefuta e mengata e fapaneng ea boleng bo loketseng ba PH (5-9), 'me boleng ba PH le alkalinity ea metsi a hloekisitsoeng li nyane. Ha thempereichara ea metsi e le tlase, e ntse e khona ho boloka boemo ba pula bo tsitsitse. Alkalinity ea eona e phahame ho feta matsoai a mang a aluminium le tšepe, 'me e na le phello e fokolang ea khoholeho ea thepa.
Kopo
PAC ke mofuta o mocha oa macromolecule coagulant e sebetsang hantle haholo. E sebelisoa haholo ka metsi a nooang, tlhoekiso ea metsi a indasteri, ts'ebetso ea likhoerekhoere tsa masepala tse litšila tsa indasteri.Ho ka lebisa ho popeho e potlakileng ea mohlape ka boholo bo boholo le pula e potlakileng. E na le maemo a fapaneng a ho ikamahanya le metsi a mocheso o fapaneng le ho qhibiliha ho hotle. PAC e senya hanyenyane 'me e loketse bakeng sa dosing ea othomathike ebile e loketse ts'ebetso.
Qetello
PAC ke coagulant ea bohlokoa tšimong ea tlhoekiso ea metsi. E na le phello e sebetsang ea tlhoekiso mochesong o tlase, moferefere o tlase le metsi a phahameng a turbidity. Leha ho le joalo, kaha monoma ea eona e sebetsana le lintho tse phelang ho hlahisa lintho tse kotsi bophelong ba batho, ho bohlokoa ho netefatsa bohloeki ba PAC tlhoekisong ea metsi.
