Umthengisi weeFlocculants zePolelectrolyte eMzantsi Afrika
Ii-polymer flocculants ezinobunzima obuphezulu beemolekyuli zokuqokelelana ngokukhawuleza kunye nokutsalwa kwezinto eziqinileyo ezixhonyiweyo emanzini, emanzini amdaka, kunye nokucutshungulwa kwezimbiwa — ii-polyelectrolytes zidibanisa amasuntswana ukuze zenze i-floc enkulu, exineneyo, nehlala ngokukhawuleza.

Zithini iiPolelectrolytes?
IiPolelectrolytes (iiflocculants ezisekwe kwi-polyacrylamide, i-PAM) ziipolymers ezenziwe ngemolekyuli ezinobunzima obuphezulu ezithwala amaqela e-ionisable charge — i-anionic (echajiwe kakubi, evela kwi-acrylic acid co-monomers), i-cationic (echajiwe kakuhle, evela kwi-quaternary ammonium okanye i-amine monomers), okanye i-non-ionic (engathathi cala, i-polyacrylamide engenamaqela atshajiweyo). Zisebenza njengeeflocculants ngendlela yokudibanisa: itshaneli nganye ye-polymer ye-high-MW inamathela kumphezulu wee-particles ezininzi ngaxeshanye, idibanisa ngokwasemzimbeni phakathi kwazo ukuze yenze ii-floc aggregates ezinkulu, ezivulekileyo, nezihlala ngokukhawuleza. IiPolelectrolytes zisetyenziswa njengesigaba sesibini senkqubo ye-coagulation-flocculation enamanqanaba amabini — emva kokuba i-inorganic coagulant (i-alum, i-ferric, i-PAC) iphazamisa i-colloidal charge, i-polyelectrolyte idibanisa i-microfloc ephumayo ibe yi-macro-floc enkulu, ehlala ngokukhawuleza.
Ukukhethwa kweeGrade ze-Anionic, zeCationic, kunye nezingezizo ze-ionic
Ukukhetha uhlobo lwe-polyelectrolyte kuxhomekeke kwisicelo: ii-anionic polyacrylamides zisetyenziswa ekucutshungulweni kwezimbiwa (ukulungiswa kwezakhi), ukucaciswa kwamanzi kamasipala (ukubopha i-floc egayiweyo), kunye nokupholisha ukungcola - amanqanaba e-anionic afunxa kwiindawo ezitshajwe kakuhle kwiindawo ze-floc; ii-cationic polyacrylamides zisetyenziselwa ukususa amanzi kwi-sludge (i-activated sludge, i-primary sludge) nakwiinkqubo ezitshajwe kakuhle; ii-non-ionic polyacrylamides zisetyenziswa apho i-pH okanye amandla e-ionic enza ukuba i-charge ingaqinisekanga, kunye nasekucutshungulweni kwezimbiwa kwiinkqubo ezithile zodongwe kunye ne-slime. Kwimigodi kunye nokucubungula izimbiwa, ii-anionic polyelectrolytes zisetyenziswa kakhulu kwi-tailings thickeners, i-paste thickeners, i-clarifiers, kunye nee-wash circuits ukuze kuhlaliswe amasuntswana amancinci eeminerali kunye nokubuyisela amanzi kwinkqubo.
Ukusetyenziswa kwiNgcali yamanzi kunye neMigodi
Kwinkqubo yamanzi kamasipala neyemizi-mveliso, ii-polyelectrolytes zongezwa kwinqanaba lokuxuba kancinci (i-flocculation) emva kokongeza i-coagulant, kwiidosi ze-polymer esebenzayo ye-0.1–2 mg/L. Ziphucula kakhulu ubungakanani be-floc, amandla, kunye nesantya sokuhlala, zonyusa ukugqitha kwe-clarifier kwaye zinciphisa ukuxinana kokugcwala. Kwinkqubo yokususa amanzi kwi-sludge, ii-polyelectrolytes ze-cationic (itshaja ephezulu, i-MW ephantsi) zibeka i-sludge esebenzayo okanye i-sludge ephambili etyebileyo ngaphambi kokuba kucinezelwe isihluzi sebhanti okanye i-centrifuges, nto leyo ephucula ukoma kwekhekhe kunye nomgangatho we-filtrate. Kwimigodi, ii-polyelectrolytes ze-anionic zezona flocculant ziphambili kwimisebenzi ye-tailings thickener - idosi ye-flocculant kunye nokukhetha kulungele uhlobo ngalunye lwe-slurry yeminerali. I-Terracore Chemicals inikezela ngamanqanaba e-anionic, cationic, kunye ne-non-ionic polyelectrolyte kwiingxowa zepowder kunye nee-emulsion drums.
