i-pH yendle
Inani le-pH lokukhucululwa kwendle linethonya elikhulu kumphumela we-flocculants.Inani le-pH lendle lihlobene nokukhethwa kwezinhlobo ze-flocculant, umthamo we-flocculants kanye nomphumela wokugoqa kanye ne-sedimentation.Lapho inani le-pH likhona<4, umphumela we-coagulation mubi kakhulu.Uma inani le-pH liphakathi kuka-6.5 no-7.5, umphumela wokuhlangana uba ngcono.Ngemuva kwe-pH value >8, umphumela we-coagulation uba mubi kakhulu futhi.
I-alkalinity emanzini inomthelela othile wokubhafa kunani le-PH.Lapho i-alkalinity yendle inganele, kufanele kwengezwe umcako namanye amakhemikhali ukuze kwengezwe.Lapho inani le-pH lamanzi liphezulu, kuyadingeka ukwengeza i-asidi ukulungisa inani le-pH lingabi hlangothi.Ngokuphambene, ama-polymer flocculants awathintwa kancane yi-pH.
izinga lokushisa lendle
Izinga lokushisa lokukhucululwa kwendle lingathinta isivinini se-flocculation se-flocculant.Lapho indle isezingeni eliphansi lokushisa, i-viscosity yamanzi iphezulu, futhi inani lokungqubuzana phakathi kwezinhlayiya ze-colloidal ezithambile kanye nezinhlayiya zokungcola emanzini ziyancipha, okuvimbela ukunamathelana kwe-flocs;ngakho-ke, nakuba umthamo we-flocculants wanda, ukwakheka kwama-flocs Kusahamba kancane, futhi kukhululekile futhi kuhlanjululwe kahle, okwenza kube nzima ukususa.
ukungcola endle
Ubukhulu obungalingani bezinhlayiya zokungcola emanzini anenzuzo ku-flocculation, ngokuphambene nalokho, izinhlayiya ezinhle nezifanayo zizoholela kumphumela ompofu we-flocculation.Ukugxila okuphansi kakhulu kwezinhlayiya zokungcola kuvame ukuba yingozi ekujimbeni.Ngalesi sikhathi, i-refluxing sediment noma ukwengeza izinsiza zokuhlanganisa kungathuthukisa umphumela wokuhlangana.
Izinhlobo ze-flocculants
Ukukhethwa kwe-flocculant ikakhulukazi kuncike emvelweni nasekugxiliseni kwezinto eziqinile ezimisiwe emanzini angcolile.Uma izinto eziqinile ezimisiwe emanzini zifana nejeli, ama-inorganic flocculants kufanele ancanyelwe ukuwohloka nokubumbana.Uma ama-flocs amancane, ama-polymer flocculants kufanele angezwe noma izinsiza zokuhlanganisa ezifana nejeli ye-silica ecushiwe kufanele isetshenziswe.
Ezimweni eziningi, ukusetshenziswa okuhlangene kwe-inorganic flocculants kanye ne-polymer flocculants kungathuthukisa kakhulu umphumela wokuhlanganisa futhi kwandise ububanzi bokusebenza.
Umthamo we-flocculant
Uma usebenzisa i-coagulation ukwelapha noma yimaphi amanzi angcolile, kukhona ama-flocculants angcono kakhulu kanye nomthamo ongcono kakhulu, ovame ukunqunywa ukuhlolwa.Umthamo oweqile ungase ubangele ukuzinzisa kabusha kwe-colloid.
Ukulandelana komthamo we-flocculant
Lapho kusetshenziswa ama-flocculants amaningi, ukulandelana kwedosi okufanelekile kudinga ukunqunywa ngokuhlolwa.Ngokuvamile, lapho ama-flocculants e-inorganic kanye nama-organic flocculants esetshenziswa ndawonye, ama-inorganic flocculants kufanele afakwe kuqala, bese kwengezwa ama-organic flocculants.
