Tšebeliso ea PAC Lefapheng la ho Etsa Lipampiri

Polyaluminium Chloride (PAC) ke k'hemik'hale ea bohlokoa indastering ea ho etsa pampiri, e bapala karolo ea bohlokoa methating e fapaneng ea ts'ebetso ea ho etsa pampiri. PAC ke coagulant e sebelisoang haholo ho ntlafatsa ho bolokoa ha likaroloana tse ntle, li-filler le likhoele, ka hona ho ntlafatsa katleho le boleng ba tlhahiso ea pampiri.

Coagulation le Flocculation

Mosebetsi oa mantlha oa PAC ho etsa lipampiri ke thepa ea eona ea coagulation le flocculation. Nakong ea mosebetsi oa ho etsa pampiri, metsi a kopantsoe le likhoele tsa cellulose ho etsa slurry. Seretse sena se na le palo e kholo ea likaroloana tse ntle le lintho tse phelang tse qhibilihisitsoeng tse hlokang ho tlosoa ho hlahisa pampiri ea boleng bo phahameng. PAC, ha e kenyelletsoa ho slurry, e fokotsa litefello tse mpe ho likaroloana tse emisitsoeng, e leng se etsang hore li kopane hammoho ho ba lihlopha tse kholoanyane kapa lihlopha. Ts'ebetso ena e thusa haholo ho tlosoa ha likaroloana tsena tse ntle nakong ea ts'ebetso ea metsi, e leng se etsang hore ho be le metsi a hlakileng le ho ntlafatsa ho boloka fiber.

Ntlafatso ea ho boloka le ho ntša metsi

Ho boloka likhoele le li-filler ho bohlokoa ho etsa pampiri kaha ho ama ka kotloloho matla a pampiri, sebopeho le boleng ka kakaretso. PAC e ntlafatsa ho bolokoa ha thepa ena ka ho etsa lihlopha tse kholoanyane tse ka bolokoang habonolo terateng ea mochini oa pampiri. Sena ha se matlafatse feela matla le boleng ba pampiri empa hape se fokotsa palo ea tahlehelo ea thepa e tala, e lebisang ho bolokeng litšenyehelo. Ho feta moo, tsamaiso e ntlafetseng ea drainage e tsamaisoang ke PAC e fokotsa metsi a pampiring, ka hona e fokotsa matla a hlokahalang bakeng sa ho omisa le ho matlafatsa ts'ebetso e akaretsang ea mosebetsi oa ho etsa pampiri.

Ntlafatso ea Boleng ba Pampiri

Tšebeliso ea PAC ho etsa pampiri e kenya letsoho haholo ntlafatsong ea boleng ba pampiri. Ka ho ntlafatsa ho bolokoa ha likotlo le li-filler, PAC e thusa ho hlahisa pampiri e nang le sebopeho se betere, se ts'oanang, le thepa ea bokaholimo. Sena se etsa hore pampiri e hatisoe hantle, e be boreleli le ponahalo e akaretsang ea pampiri, e leng se etsang hore e tšoanelehe bakeng sa lisebelisoa tsa boleng bo holimo tsa khatiso le ho paka.

Phokotso ea BOD le COD ho Phekolo ea Metsi a Litšila ka Pampiri

Biochemical Oxygen Demand (BOD) le Chemical Oxygen Demand (COD) ke litekanyo tsa palo ea lintho tse phelang tse teng metsing a litšila a hlahisoang ke mokhoa oa ho etsa pampiri. Maemo a phahameng a BOD le COD a bontša boemo bo phahameng ba tšilafalo, bo ka senyang tikoloho. PAC e atleha ho fokotsa maemo a BOD le COD ka ho kopanya le ho tlosa litšila tse tsoang metsing a litšila. Sena ha se thuse feela ho finyella melao ea tikoloho empa hape se fokotsa litšenyehelo tsa ho hloekisa tse amanang le tsamaiso ea metsi a litšila.

Ka kakaretso, polyaluminium chloride ke tlatsetso ea bohlokoa indastering ea ho etsa pampiri, e fanang ka melemo e mengata e ntlafatsang katleho ea mokhoa oa ho etsa pampiri le boleng ba sehlahisoa sa ho qetela. Karolo ea eona ea ho kopanya le ho phalla, ho boloka le ho phalla ha metsi, phokotso ea BOD le COD, le ntlafatso e akaretsang ea boleng ba pampiri e etsa hore e be karolo ea bohlokoa ho etsa pampiri ea sejoale-joale.
