Thaum lub sij hawm coagulation, thaum PFS muab cov nucleohydroxy complexes ntawm ntau yam Cheebtsam, txhua feem pib exert ntau coagulation teebmeem ntawm microparticles nyob rau hauv slurry los yog colloidal hais nyob rau hauv dej. Cov siab -valence complex ions nrog me me molecular luj yog attracted rau lub compact txheej los ntawm tsis zoo nqi colloidal hais thiab tshem tawm cov khib nyiab nyob rau hauv cov dej nyoos, compressing hluav taws xob ob txheej ntawm cov colloidal hais thiab txo cov zeta muaj peev xwm, ua rau cov colloidal hais kom sai destabilize thiab aggregate. Cov inorganic polymeric coagulant muaj qhov sib npaug ntawm qhov hnyav molecular, nce extensibility, thiab ntau cov ntsiab lus sib cuag, uas ua rau muaj kev cuam tshuam ntau ntxiv.
Hauv kev daws, PFS muab ntau cov macromolecular complexes thiab hydrophobic hydroxide polymers, nthuav tawm cov khoom zoo adsorption. Txawm li cas los xij, ntau yam nucleohydroxy complexes hauv PFS cov tshuaj sib txawv ntawm cov organic polymeric flocculants; Qhov sib txheeb molecular hnyav ntawm cov polymers no ntau me dua li cov organic flocculants. Lawv qhov loj me me thiab cov yam ntxwv ntawm cov qauv muab cov ions nyuaj no ua rau muaj zog adsorption thiab neutralization nyhuv thaum coagulation. Yog li ntawd, qhov tseem ceeb ntawm qhov siab -valence macromolecular complex ions nyob rau hauv PFS tov rau coagulation yog lub adsorption thiab neutralization ntawm tus nqi ntawm colloidal hais, nrog rau cov interparticle aggregation. PFS flocs muaj thaj chaw loj loj thiab lub zog saum npoo av, thiab cov qauv compact thiab ntom nrog qee lub zog. Thaum lub sij hawm sedimentation, lawv muaj peev xwm adsorption loj rau colloidal hais, nthuav tawm adsorption co- nag lossis daus thiab yooj yim cheb deposition. Lub precipitate muaj me me ntim thiab ceev sedimentation tus nqi, uas zoo heev txhim kho cov coagulation nyhuv ntawm PFS.
