Polyaluminium chlorideke flocculant e sebetsang hantle haholo, e atisang ho sebelisoa ho hloekisa likhoerekhoere tsa masepala le ho hloekisa metsi a litšila a indasteri. E na le litšobotsi tsa ts'ebetso e phahameng le botsitso. Ha re bua ka PAC, e ‘ngoe ea li- indicator tseo hangata ho buuoang ka tsona ke basicity . Joale motheo ke eng? Basicity e na le phello efe boleng ba polyaluminium chloride? Ho utloisisa mohopolo ona ho tla ba le tšusumetso e kholo khethong ea polyaluminium chloride.
Motheo oa polyaluminium chloride ke eng?
Ho PAC, basicity e bua ka karolelano ea molar ea lihlopha tsa hydroxyl ho li-ion tsa aluminium. Hangata e hlalosoa e le motheo (B):
B = [OH-] / [Al3+]
Basicity ke e 'ngoe ea matšoao a bohlokoa ka ho fetisisa a ts'ebetso ea polyaluminium chloride. E ama ka kotloloho phello ea flocculation ea PAC.
Khamphani ea rona e fana ka mefuta e fapaneng ea PAC ka motheo ho tloha ho 40% ho isa ho 90%.
Mokhoa oa tšusumetso ea motheo ho polyaluminium chloride
Basicity e ama ts'ebetso ea PAC ka ho ama polymer morphology le kabo ea litefiso ea PAC. Alkalinity e etsa qeto ea tekanyo ea polymerization ea aluminium hydroxyl complexes ho PAC. Taba ea mantlha e phahameng e thusa ho thehoeng ha PAC e nang le degree e phahameng ea polymerization mme e ntlafatsa phello ea eona ea flocculation. 'Me motheo o tla ama kabo e ntle ea tefiso ea PAC le bokhoni ba eona ba ho bapatsa bakeng sa lintho tse qosoang hampe.
Phello ea motheo ho PAC:
Boleng bo nepahetseng bo ka ntlafatsa phello ea flocculation ea polyaluminium chloride. Boemo bo tlase haholo bo tla lebisa ho hydrolysis e sa lekaneng ea PAC le ho fokotsa phello ea flocculation.
Basicity e tla ama boholo, sekhahla le sekhahla sa sedimentation sa li-condensed flocs tsa polyaluminium chloride. Bohlokoa bo loketseng bo ka sebetsana le ntlha ena hantle haholo.
Ka hona, ho bohlokoa haholo ho khetha mofuta o nepahetseng oa PAC ho latela litlhoko tsa hau.
Re ka fana ka mefuta e latelang ea PAC:

Re tsamaisa taolo e tiileng ea boleng lifemeng tsa rona tsa balekane ba polyaluminium chloride mme re ka etsa likhothaletso tse nepahetseng tsa mohlala ho latela litlhoko tse fapaneng tsa bareki, re fa bareki PAC ea boleng bo holimo e fihlelang litlhoko tsa bona. Sehlopha sa rona sa thekiso se na le boiphihlelo bo bongata khethong ea lihlahisoa mme se ka fa bareki boeletsi ba litsebi le lisampole tse tšoanelehang haholo bakeng sa bareki ho etsa liteko tsa beaker.
Haeba u batla e ka tšeptjoangMofani oa PACbakeng sa ho hloekisa metsi a nooang, ho hloekisa metsi a litšila a indasteri kapa lisebelisoa tse ling, re ka fana ka tloaelo ea PAC ho finyella litlhoko tsa hau. Ikopanye le rona hona joale ho ithuta haholoanyane ka lihlahisoa tsa rona tsa PAC tse sebetsang hantle haholo le ho fumana qotsulo ea tlholisano!
