pH yogutyulo
Ixabiso le-pH lamanzi amdaka linempembelelo enkulu kwisiphumo se-flocculants.Ixabiso le-pH yamanzi amdaka linxulumene nokukhethwa kweentlobo ze-flocculant, i-dosage of flocculants kunye nefuthe le-coagulation kunye ne-sedimentation.Xa ixabiso le-pH li<4, i-coagulation effect imbi kakhulu.Xa ixabiso le-pH liphakathi kwe-6.5 kunye ne-7.5, umphumo we-coagulation ungcono.Emva kwexabiso le-pH>8, i-coagulation effect iba yimbi kakhulu kwakhona.
I-alkalinity kugutyulo inesiphumo esithile sokuthintela kwixabiso le-PH.Xa i-alkalinity yelindle ingonelanga, i-lime kunye nezinye iikhemikhali kufuneka zongezwe ukongeza kuyo.Xa ixabiso le-pH lamanzi liphezulu, kuyimfuneko yokongeza i-asidi ukulungisa ixabiso le-pH ukungathathi hlangothi.Ngokwahlukileyo, ii-polymer flocculants azichatshazelwa kangako yi-pH.
ubushushu belindle
Ukushisa kwamanzi amdaka kunokuchaphazela isantya se-flocculation ye-flocculant.Xa amanzi amdaka ephantsi kweqondo lokushisa eliphantsi, i-viscosity yamanzi iphezulu, kwaye inani lokungqubuzana phakathi kweengqungquthela ze-flocculant colloidal kunye neengqungquthela ezingcolileyo emanzini ziyancipha, ezithintela ukubambelela ngokubambisana kweeflocs;ngoko ke, nangona i-dosage ye-flocculants yanda, ukubunjwa kwee-flocs Kusacotha, kwaye ikhululekile kwaye icolile, okwenza kube nzima ukuyisusa.
ukungcola kwilindle
Ubungakanani obungalinganiyo bamasuntswana okungcola kumanzi amdaka bunenzuzo kwi-flocculation, ngokuchaseneyo, i-fine and uniform particles iya kukhokelela kwisiphumo esibi se-flocculation.Ukuxinana okuphantsi kakhulu kwamasuntswana okungcola kudla ngokuba yingozi ekujimeni.Ngeli xesha, i-refluxing sediment okanye ukongeza i-coagulation aids inokuphucula i-coagulation effect.
Iintlobo zeeflocculants
Ukukhetha i-flocculant ikakhulu kuxhomekeke kubume kunye nokuxinana kwezinto eziqinileyo ezimisiweyo kugutyulo.Ukuba izinto eziqinileyo ezimisiweyo kugutyulo zifana nejeli, i-inorganic flocculants kufuneka ikhethwe ukuze ingazinzi kwaye ijiyane.Ukuba iiflocs zincinci, i-polymer flocculants kufuneka yongezwe okanye i-coagulation aids efana ne-silica gel esebenzayo kufuneka isetyenziswe.
Kwiimeko ezininzi, ukusetyenziswa okudibeneyo kwe-inorganic flocculants kunye ne-polymer flocculants kunokuphucula kakhulu umphumo we-coagulation kunye nokwandisa umda wokusetyenziswa.
Umthamo we-flocculant
Xa usebenzisa i-coagulation ukunyanga nawaphi na amanzi amdaka, kukho ezona flocculants zibalaseleyo kunye nedosi egqwesileyo, edla ngokumiselwa yimifuniselo.Ukugqithiswa kwedosi kunokubangela ukuzinzisa kwakhona kwe-colloid.
Ulandelelwano lwethamo lwe-flocculant
Xa kusetyenziswa iiflocculants ezininzi, ulandelelwano lwedosi olulolona lufanelekileyo lufuna ukumiselwa ngemifuniselo.Ngokuqhelekileyo, xa iiflocculants ze-inorganic kunye ne-organic flocculants zisetyenziswa kunye, i-inorganic flocculants kufuneka yongezwe kuqala, kwaye emva koko i-organic flocculants kufuneka yongezwe.
