Coagulation thiab Flocculation, txawm hais tias koom nrog tib txoj kev kho dej, ua haujlwm sib txawv kiag li.

Coagulation yog lub luag haujlwm rau kev ua kom tiav cov nqi nruab nrab kom ua kom cov khoom colloidal poob stability; Flocculation, los ntawm kev sib xyaw qeeb, tso cai rau micro-flocs kom tsis tu ncua sib tsoo, choj, thiab loj hlob mus rau hauv cov khoom loj loj uas yooj yim rau kev sib haum xeeb.

Raws li kev ua haujlwm zoo inorganic polymer coagulant,Polyaluminium chloride (PAC)Tsis tuaj yeem ua kom tiav Coagulation sai sai tab sis tseem txhawb nqa kev loj hlob ntawm floc thaum lub sij hawm Flocculation. Los ntawm kev tsim tsim nyog ntawm kev sib xyaw sai, qeeb flocculation, thiab ua ke PAC thiab PAM dosing schemes, turbidity tshem tawm tus nqi, tshem tawm cov khib nyiab tshem tawm, thiab tag nrho kev ua haujlwm ruaj khov tuaj yeem txhim kho tau zoo.

Rau kev lag luam xws li kev lim dej haus, kev kho dej hauv nroog, kev kho dej khib nyiab, kev kho cov dej khib nyiab, nrog rau cov ntaub ntawv thiab textile dyeing, kev nkag siab tob txog kev ua haujlwm ntawm Coagulation thiab Flocculation yog lub hauv paus tseem ceeb rau optimizing PAC daim ntawv thov cuam tshuam, txo cov nqi khiav lag luam, thiab txhim kho kev kho mob.
