PAM bakeng sa Phekolo ea Metsi
Selelekela
Polyacrylamide (PAM)ke sesebelisoa se sebetsang hantle haholo sa ho hloekisa metsi se etselitsoeng ho matlafatsa ts'ebetso ea ho hlakisa metsi le lits'ebetso tsa tlhoekiso.PAM ea rona bakeng sa Phekolo ea Metsi ke tharollo ea sejoale-joale e etselitsoeng ho fihlela litlhoko tse fapaneng tsa liindasteri tse itšetlehileng ka taolo e sebetsang ea metsi, ho kenyeletsoa limela tsa ho hloekisa metsi a litšila, lits'ebeletso tsa indasteri le lits'ebetso tsa ho hloekisa metsi a masepala.

Likarolo tsa Bohlokoa
Ts'ebetso e ikhethang ea Flocculation:
Sehlahisoa sa rona sa PAM se ipabola ho khothaletse flocculation, ts'ebetso ea bohlokoa kalafong ea metsi.E kopanya ka potlako likaroloana tse emisitsoeng, ho nolofatsa ho tlosoa ha tsona habonolo ka sedimentation kapa filtration.Sena se lebisa ntlafatsong ea ho hlaka le boleng ba metsi.
Mefuta-futa ea Mehloli ea Metsi:
Hore na re hloekisa metsi a litšila a indasteri, metsi a masepala, kapa metsi a sebetsoang, PAM ea rona ea Phekolo ea Metsi e bonts'a mekhoa e mengata e fapaneng.Ho ikamahanya le maemo ho mehloli e fapaneng ea metsi ho etsa hore e be khetho e tšepahalang bakeng sa mefuta e mengata ea lits'ebetso.
Tharollo e Sebeletsang Litšenyehelo:
E etselitsoe ho sebetsa hantle, PAM ea rona e thusa ho ntlafatsa ts'ebetso ea ho hloekisa metsi ka kakaretso, ho fokotsa tlhokahalo ea lik'hemik'hale tse feteletseng le tšebeliso ea matla.Sena, ka lehlakoreng le leng, se fetolela ho boloka litšenyehelo bakeng sa bareki ba rona ha re ntse re boloka maemo a holimo a ts'ebetso.
Tlhokahalo ea Tekanyetso e Tlase:
Ka tlhokahalo e tlase ea litekanyetso, PAM ea rona bakeng sa Phekolo ea Metsi e netefatsa ts'ebetso ea kalafo e baballang chelete e ngata.Karolo ena ha e thuse feela melemo ea moruo empa e boetse e fokotsa tšusumetso ea tikoloho e amanang le tšebeliso e feteletseng ea lik'hemik'hale.
Ho qhibiliha ka potlako le ho kopanya:
Sehlahisoa se etselitsoe ho qhibiliha ka potlako le ho kopanya habonolo, ho etsa bonnete ba hore ho kopantsoe ka mokhoa o se nang moeli ho mekhoa e teng ea ho hloekisa metsi.Tšobotsi ena e lumella mokhoa oa phekolo o sebetsang hantle le o bonolo.
Ho lumellana le Coagulants:
PAM ea rona e tsamaisana le li-coagulants tse fapaneng, e ntlafatsang ts'ebetso ea eona e tsamaisanang le lik'hemik'hale tse ling tsa ho hloekisa metsi.Ho ikamahanya le maemo ho netefatsa ts'ebetso e nepahetseng maemong a fapaneng a kalafo ea metsi.
Lisebelisoa
Phekolo ea Metsi ea Masepala:
PAM ea rona bakeng sa Phekolo ea Metsi e loketse litsi tsa masepala tse hloekisang metsi, e thusa ho tlosa litšila le litšila, kahoo e netefatsa phano ea metsi a nooang a bolokehileng le a hloekileng metseng.
Phekolo ea metsi a litšila a indasteri:
Liindasteri li rua molemo ho bokhoni ba sehlahisoa sa ho rarolla mathata a rarahaneng a metsi a litšila, ho khothaletsa karohano e nepahetseng ea lintho tse tiileng le tse metsi, le ho kopana le litekanyetso tsa taolo bakeng sa ho tsoa.
Phekolo ea Metsi:
Ntlafatsa boleng ba metsi a sebetsang lifemeng tsa tlhahiso, ho netefatsa hore lits'ebetso tsa indasteri li tsamaea hantle ka litšenyehelo tse fokotsehileng tsa nako le tlhokomelo.
Merafo le Ts'ebetso ea Liminerale:
PAM ea rona e atleha ho hlakisa metsi a sebelisoang merafong le ts'ebetsong ea liminerale, ho thusa ho tlosoa ha likaroloana tse emisitsoeng le litšila.
