Phapang lipakeng tsa polyaluminium chloride le polyaluminium ferric chloride

Aluminium chloride (Pac) le polyaluminium ferric chloride (PAFC) ke li-polymer flocculants tse peli tse sebelisoang ka tloaelo, liphapang tse kholo ke tse latelang:

1. Liphapang tsa sebopeho le ponahalo

● Polyaluminium chloride (PAC)
● Haholo-holo e entsoe ka aluminium, 'me boholo ba eona ke' mala o mosehla, beige kapa o mosoeu (sekhahla sa metsi a nooang a hloekileng haholo).
● Polyaluminium ferric chloride (PAFC)
● Aluminium le tšepe (litekanyo tsa tšepe tse ka bang 2-10%) li teng 'me li bonahala li le bofubelu bo sootho kapa bo sootho.

2. Lisebelisoa tse tala le mokhoa oa tlhahiso

● PAC e tala
● Kereiti ea metsi a nooang e hloka phofo ea aluminium hydroxide, sehlopha sa indasteri se ka sebelisa molora oa aluminium, slag ea aluminium le lisebelisoa tse ling tsa litšila.
● PAFC lihlahisoa tse tala
● E etsoa ka ho sebelisa phofo ea aluminium calcium kapa thepa e tala e nang le tšepe (e kang ferric chloride) ha e kopane.
● boenjiniere ba tlhahiso
● PAC e atisa ho sebelisoa mokhoa oa ho omisa (bohloeki bo phahameng), PAFC e sebelisoa haholo ka mokhoa oa ho omisa moropa.

3. Sebaka sa kopo le phello ea phekolo

● Maemo a kopo ea PAC
● Ho noa Tlhoekiso ea Metsi: metsi a hloekisitsoeng a bonolo 'me ha ho na kotsi e setseng ea ion ea aluminium.
● Moferefere o tlaase Phekolo ea Metsi: joalo ka tlhoekiso ea metsi a noka, thibela ho thatafala ha lesela.
● maemo a kopo ea PAFC
● Metsi a litšila a phahameng a liindasteri: liloala tsa tšepe, limilone tsa pampiri, limela tsa likhoerekhoere, joalo-joalo, lebelo la flocculation le potlakile, phello ea sedimentation e bohlokoa.
● Mocheso o tlase oa metsi a turbid: element ea tšepe e ntlafatsa ho ikamahanya le mocheso o tlase.

4. Ts'ebetso le litšenyehelo

● Molemo oa PAC
● Tšireletseho e phahameng, e loketseng ho hloekisa metsi a nooang;
● Phello ea ho tlosa lintho tse phelang le chromaticity e molemo.
● Molemo oa PAFC
● Ho beha palesa ho teteaneng le ka potlako ho loketse metsi a litšila a thata haholo;
● Theko e tlase, e boloka 10-20% ea litšenyehelo tsa moemeli ha e bapisoa le PAC.

5. Litlhokomelo

● Moeli oa PAC: phello ea phekolo ea mocheso o tlaase le metsi a tlaase a mongobo a futsanehile.
● Tekanyetso ea PAFC: likahare tsa tšepe li ka ama 'mala oa litšila hanyenyane 'me ha lia lokela metsi a nooang.

Akaretsa likhothaletso

● Khetha PAC: metsi a nooang, metsi a litšila a tlaase kapa libaka tse hlokang taolo e tiileng ea aluminium.
● Khetha PAFC: metsi a litšila a indasteri, moferefere o phahameng kapa liketsahalo tse hlokang sedimentation e potlakileng.
